Good for your bones and good for art conservation: calcium

The statues on Easter Island, the Great Wall of China, Egyptian pyramids, MesoAmerican pyramids, castles in Europe and other structures made of stone are deteriorating and now comes another approach to halting the destruction. (I have covered other approaches to the problem in two previous postings, a December 5, 2017 posting, Europe’s cathedrals get a ‘lift’ with nanoparticles, and an October 21, 2014 posting, Heart of stone.)

An August 7, 2019 news item on ScienceDaily announces the latest in conserving stone monuments and structures,

When it comes to cultural heritage sites, there are few things historians wouldn’t do to preserve them for future generations. In particular, stone buildings and sculptures made of plaster and marble are increasingly at risk of damage from air pollution, acid rain and other factors. Researchers now report a new, calcium-based conservation treatment inspired by nature that overcomes many drawbacks of currently used methods.

An August 7, 2019 American Chemical Society (ACS) news release, which originated the news item, provides a bit more technical detail,

Historically, conservation scientists have turned to alkoxysilanes, silicon-based molecules used to consolidate stone and other artworks, in their preservation efforts. However, alkoxysilane treatments do not bond properly with non-silicate surfaces, are prone to cracking and are limited in their ability to repel water. Adding other compounds to this treatment have helped overcome these effects, but only to a point. Instead Encarnación Ruiz Agudo and colleagues looked to nature for inspiration, and found that calcium could be the answer. As a major element of strong, natural structures like bone and kidney stones, the researchers theorized that nanoparticles made from calcium could bolster alkoxysilanes and provide the desired protective effects to conserve historical artifacts.

The researchers made calcium carbonate and calcium oxalate nanoparticles and included polydimethylsiloxane (PDMS) as a stabilizer. PDMS also likely helps the nanoparticles bond to surfaces. The team added the nanoparticles to traditional alkoxysilane treatments, then applied them to samples of three different building materials: white marble, calcarenite limestone and gypsum plaster, and put the samples through a battery of tests. Overall, the results showed enhanced hydrophobicity, less cracking and improved surface adhesion compared to alkoxysilane treatments alone, with calcium oxalate providing a marked improvement in acid resistance. A minimal color effect was observed, but the researchers say this change was within acceptable values for conservation efforts.

More of the ‘blackest black’

There’s a very good November 11, 2019 article by Natalie Angier for the New York Times on carbon nanotubes (CNTs) and the colour black,

On a laboratory bench at the National Institute of Standards and Technology was a square tray with two black disks inside, each about the width of the top of a Dixie cup. Both disks were undeniably black, yet they didn’t look quite the same.

Solomon Woods, 49, a trim, dark-haired, soft-spoken physicist, was about to demonstrate how different they were, and how serenely voracious a black could be.

“The human eye is extraordinarily sensitive to light,” Dr. Woods said. Throw a few dozen photons its way, a few dozen quantum-sized packets of light, and the eye can readily track them.

Dr. Woods pulled a laser pointer from his pocket. “This pointer,” he said, “puts out 100 trillion photons per second.” He switched on the laser and began slowly sweeping its bright beam across the surface of the tray.

On hitting the white background, the light bounced back almost unimpeded, as rude as a glaring headlight in a rearview mirror.

The beam moved to the first black disk, a rondel of engineered carbon now more than a decade old. The light dimmed significantly, as a sizable tranche of the incident photons were absorbed by the black pigment, yet the glow remained surprisingly strong.

Finally Dr. Woods trained his pointer on the second black disk, and suddenly the laser’s brilliant beam, its brash photonic probe, simply — disappeared. Trillions of light particles were striking the black disk, and virtually none were winking back up again. It was like watching a circus performer swallow a sword, or a husband “share” your plate of French fries: Hey, where did it all go?

N.I.S.T. disk number two was an example of advanced ultra-black technology: elaborately engineered arrays of tiny carbon cylinders, or nanotubes, designed to capture and muzzle any light they encounter. Blacker is the new black, and researchers here and abroad are working to create ever more efficient light traps, which means fabricating materials that look ever darker, ever flatter, ever more ripped from the void.

The N.I.S.T. ultra-black absorbs at least 99.99 percent of the light that stumbles into its nanotube forest. But scientists at the Massachusetts Institute of Technology reported in September the creation of a carbon nanotube coating that they claim captures better than 99.995 of the incident light.

… The more fastidious and reliable the ultra-black, the more broadly useful it will prove to be — in solar power generators, radiometers, industrial baffles and telescopes primed to detect the faintest light fluxes as a distant planet traverses the face of its star.

Psychology and metaphors

It’s not all technical, Angier goes on to mention the psychological and metaphorical aspects,

Psychologists have gathered evidence that black is among the most metaphorically loaded of all colors, and that we absorb our often contradictory impressions about black at a young age.

Reporting earlier this year in the Quarterly Journal of Experimental Psychology, Robin Kramer and Joanne Prior of the University of Lincoln in the United Kingdom compared color associations in a group of 104 children, aged 5 to 10, with those of 100 university students.

The researchers showed subjects drawings in which a lineup of six otherwise identical images differed only in some aspect of color. The T-shirt of a boy taking a test, for example, was switched from black to blue to green to red to white to yellow. The same for a businessman’s necktie, a schoolgirl’s dress, a dog’s collar, a boxer’s gloves.

Participants were asked to link images with traits. Which boy was likeliest to cheat on the test? Which man was likely to be in charge at work? Which girl was the smartest in her class, which dog the scariest?

Again and again, among both children and young adults, black pulled ahead of nearly every color but red. Black was the color of cheating, and black was the color of cleverness. A black tie was the mark of a boss, a black collar the sign of a pit bull. Black was the color of strength and of winning. Black was the color of rage.

Art

Then, there is the world of art,

For artists, black is basal and nonnegotiable, the source of shadow, line, volume, perspective and mood. “There is a black which is old and a black which is fresh,” Ad Reinhardt, the abstract expressionist artist, said. “Lustrous black and dull black, black in sunlight and black in shadow.”

So essential is black to any aesthetic act that, as David Scott Kastan and Stephen Farthing describe in their scholarly yet highly entertaining book, “On Color,” modern artists have long squabbled over who pioneered the ultimate visual distillation: the all-black painting.

Was it the Russian Constructivist Aleksandr Rodchenko, who in 1918 created a series of eight seemingly all-black canvases? No, insisted the American artist Barnett Newman: Those works were very dark brown, not black. He, Mr. Newman, deserved credit for his 1949 opus, “Abraham,” which in 1966 he described as “the first and still the only black painting in history.”

But what about Kazimir Malevich’s “Black Square” of 1915? True, it was a black square against a white background, but the black part was the point. Then again, the English polymath Robert Fludd had engraved a black square in a white border back in 1617.

Clearly, said Alfred H. Barr, Jr., the first director of the Museum of Modern Art, “Each generation must paint its own black square.”

Structural colour

Solomon and his NIST colleagues and the MIT scientists are all trying to create materials with structural colour, in this case, black. Angier goes on to discuss structural colour in nature mentioning bird feathers and spiders as examples of where you might find superblacks. For anyone unfamiliar with structural colour, the colour is not achieved with pigment or dye but with tiny structures, usually measured at the nanoscale, on a bird’s wing, a spider’s belly, a plant leaf, etc. Structural colour does not fade or change . Still, it’s possible to destroy the structures, i.e., the colour, but light and time will not have any effect since it’s the tiny structures and their optical properties which are producing the colour . (Even after all these years, my favourite structural colour story remains a Feb. 1, 2013 article, Color from Structure, by Cristina Luiggi for The Scientist magazine. For a shorter version, I excerpted parts of Luiggi’s story for my February 7, 2013 posting.)

The examples of structural colour in Angier’s article were new to me. However, there are many, many examples elsewhere,. You can find some here by using the terms ‘structural colour’ or ‘structural color’ in the blog’s search engine.

Angier’s is a really good article and I strongly recommend reading it if you have time but I’m a little surprised she doesn’t mention Vantablack and the artistic feud. More about that in a moment,

Massachusetts Institute of Technology and a ‘blacker black’

According to MIT (Massachusetts Institute of Technology), they have the blackest black. It too is courtesy of carbon nanotubes.

The Redemption of Vanity, is a work of art by MIT artist in residence Diemut Strebe that has been realized together with Brian L. Wardle, Professor of Aeronautics and Astronautics and Director of necstlab and Nano- Engineered Composite aerospace STructures (NECST) Consortium and his team Drs. Luiz Acauan and Estelle Cohen. Strebe’s residency at MIT is supported by the Center for Art, Science & Technology (CAST). Image: Diemut Strebe

What you see in the above ‘The Redemption of Vanity’ was on show at the New York Stock Exchange (NYSE) from September 13 – November 29, 2019. It’s both an art piece and a demonstration of MIT’s blackest black.

There are two new releases from MIT. The first is the more technical one. From a Sept. 12, 2019 MIT news release,

With apologies to “Spinal Tap,” it appears that black can, indeed, get more black.

MIT engineers report today that they have cooked up a material that is 10 times blacker than anything that has previously been reported. The material is made from vertically aligned carbon nanotubes, or CNTs — microscopic filaments of carbon, like a fuzzy forest of tiny trees, that the team grew on a surface of chlorine-etched aluminum foil. The foil captures at least 99.995 percent* of any incoming light, making it the blackest material on record.

The researchers have published their findings today in the journal ACS-Applied Materials and Interfaces. They are also showcasing the cloak-like material as part of a new exhibit today at the New York Stock Exchange, titled “The Redemption of Vanity.”

The artwork, conceived by Diemut Strebe, an artist-in-residence at the MIT Center for Art, Science, and Technology, in collaboration with Brian Wardle, professor of aeronautics and astronautics at MIT, and his group, and MIT Center for Art, Science, and Technology artist-in-residence Diemut Strebe, features a 16.78-carat natural yellow diamond from LJ West Diamonds, estimated to be worth $2 million, which the team coated with the new, ultrablack CNT material. The effect is arresting: The gem, normally brilliantly faceted, appears as a flat, black void.

Wardle says the CNT material, aside from making an artistic statement, may also be of practical use, for instance in optical blinders that reduce unwanted glare, to help space telescopes spot orbiting exoplanets.

“There are optical and space science applications for very black materials, and of course, artists have been interested in black, going back well before the Renaissance,” Wardle says. “Our material is 10 times blacker than anything that’s ever been reported, but I think the blackest black is a constantly moving target. Someone will find a blacker material, and eventually we’ll understand all the underlying mechanisms, and will be able to properly engineer the ultimate black.”

Wardle’s co-author on the paper is former MIT postdoc Kehang Cui, now a professor at Shanghai Jiao Tong University.

Into the void

Wardle and Cui didn’t intend to engineer an ultrablack material. Instead, they were experimenting with ways to grow carbon nanotubes on electrically conducting materials such as aluminum, to boost their electrical and thermal properties.

But in attempting to grow CNTs on aluminum, Cui ran up against a barrier, literally: an ever-present layer of oxide that coats aluminum when it is exposed to air. This oxide layer acts as an insulator, blocking rather than conducting electricity and heat. As he cast about for ways to remove aluminum’s oxide layer, Cui found a solution in salt, or sodium chloride.

At the time, Wardle’s group was using salt and other pantry products, such as baking soda and detergent, to grow carbon nanotubes. In their tests with salt, Cui noticed that chloride ions were eating away at aluminum’s surface and dissolving its oxide layer.

“This etching process is common for many metals,” Cui says. “For instance, ships suffer from corrosion of chlorine-based ocean water. Now we’re using this process to our advantage.”

Cui found that if he soaked aluminum foil in saltwater, he could remove the oxide layer. He then transferred the foil to an oxygen-free environment to prevent reoxidation, and finally, placed the etched aluminum in an oven, where the group carried out techniques to grow carbon nanotubes via a process called chemical vapor deposition.

By removing the oxide layer, the researchers were able to grow carbon nanotubes on aluminum, at much lower temperatures than they otherwise would, by about 100 degrees Celsius. They also saw that the combination of CNTs on aluminum significantly enhanced the material’s thermal and electrical properties — a finding that they expected.

What surprised them was the material’s color.

“I remember noticing how black it was before growing carbon nanotubes on it, and then after growth, it looked even darker,” Cui recalls. “So I thought I should measure the optical reflectance of the sample.

“Our group does not usually focus on optical properties of materials, but this work was going on at the same time as our art-science collaborations with Diemut, so art influenced science in this case,” says Wardle.

Wardle and Cui, who have applied for a patent on the technology, are making the new CNT process freely available to any artist to use for a noncommercial art project.

“Built to take abuse”

Cui measured the amount of light reflected by the material, not just from directly overhead, but also from every other possible angle. The results showed that the material absorbed at least 99.995 percent of incoming light, from every angle. In other words, it reflected 10 times less light than all other superblack materials, including Vantablack. If the material contained bumps or ridges, or features of any kind, no matter what angle it was viewed from, these features would be invisible, obscured in a void of black.  

The researchers aren’t entirely sure of the mechanism contributing to the material’s opacity, but they suspect that it may have something to do with the combination of etched aluminum, which is somewhat blackened, with the carbon nanotubes. Scientists believe that forests of carbon nanotubes can trap and convert most incoming light to heat, reflecting very little of it back out as light, thereby giving CNTs a particularly black shade.

“CNT forests of different varieties are known to be extremely black, but there is a lack of mechanistic understanding as to why this material is the blackest. That needs further study,” Wardle says.

The material is already gaining interest in the aerospace community. Astrophysicist and Nobel laureate John Mather, who was not involved in the research, is exploring the possibility of using Wardle’s material as the basis for a star shade — a massive black shade that would shield a space telescope from stray light.

“Optical instruments like cameras and telescopes have to get rid of unwanted glare, so you can see what you want to see,” Mather says. “Would you like to see an Earth orbiting another star? We need something very black. … And this black has to be tough to withstand a rocket launch. Old versions were fragile forests of fur, but these are more like pot scrubbers — built to take abuse.”

[Note] An earlier version of this story stated that the new material captures more than 99.96 percent of incoming light. That number has been updated to be more precise; the material absorbs at least 99.995 of incoming light.

Here’s an August 29, 2019 news release from MIT announcing the then upcoming show. Usually I’d expect to see a research paper associated with this work but this time it seems to an art exhibit only,

The MIT Center for Art, Science &Technology (CAST) and the New York Stock Exchange (NYSE) will present The Redemption of Vanity,created by artist Diemut Strebe in collaboration with MIT scientist Brian Wardle and his lab, on view at the New York Stock Exchange September 13, 2019 -November 25, 2019. For the work, a 16.78 carat natural yellow diamond valued at $2 million from L.J.West was coated using a new procedure of generating carbon nanotubes (CNTs), recently measured to be the blackest black ever created, which makes the diamond seem to disappear into an invisible void. The patented carbon nanotube technology (CNT) absorbs more than 99.96% of light and was developed by Professor Wardle and his necstlablab at MIT.

“Any object covered with this CNT material loses all its plasticity and appears entirely flat, abbreviated/reduced to a black silhouette. In outright contradiction to this we see that a diamond,while made of the very same element (carbon) performs the most intense reflection of light on earth.Because of the extremely high light absorbtive qualities of the CNTs, any object, in this case a large diamond coated with CNT’s, becomes a kind of black hole absent of shadows,“ explains Strebe.“The unification of extreme opposites in one object and the particular aesthetic features of the CNTs caught my imagination for this art project.”

“Strebe’s art-science collaboration caused us to look at the optical properties of our new CNT growth, and we discovered that these particular CNTs are blacker than all other reported materials by an order of magnitude across the visible spectrum”, says Wardle. The MIT team is offering the process for any artist to use. “We do not believe in exclusive ownership of any material or idea for any artwork and have opened our method to any artist,” say Strebe and Wardle.“

The project explores material and immaterial value attached to objects and concepts in reference to luxury, society and to art. We are presenting the literal devaluation of a diamond, which is highly symbolic and of high economic value.It presents a challenge to art market mechanisms on the one hand, while expressing at the same time questions of the value of art in a broader way. In this sense it manifests an inquiry into the significance of the value of objects of art and the art market,” says Strebe. “We are honored to present this work at The New York Stock Exchange, which I believe to be a most fitting location to consider the ideas embedded in The Redemption of Vanity.”

“The New York Stock Exchange, a center of financial and technological innovation for 227 years, is the perfect venue to display Diemut Strebe and Professor Brian Wardle’s collaboration. Their work brings together cutting-edge nanotube technology and a natural diamond, which is a symbol of both value and longevity,” said John Tuttle, NYSE Group Vice Chairman & Chief Commercial Officer.

“We welcome all scientists and artists to venture into the world of natural color diamonds. The Redemption of Vanity exemplifies the bond between art, science, and luxury. The 16-carat vivid yellow diamond in the exhibit spent millions of years in complete darkness, deep below the earth’s surface. It was only recently unearthed —a once-in-a-lifetime discovery of exquisite size and color. Now the diamond will relive its journey to darkness as it is covered in the blackest of materials. Once again, it will become a reminder that something rare and beautiful can exist even in darkness,”said Larry West.

The “disappearing” diamond in The Redemption of Vanity is a $2 Million Fancy Vivid Yellow SI1 (GIA), Radiant shape, from color diamond specialist, L.J. West Diamonds Inc. of New York.

The Redemption of Vanity, conceived by Diemut Strebe, has been realized with Brian L. Wardle, Professor of Aeronautics and Astronautics and Director of necstlab and Nano-Engineered Composite aerospace STructures (NECST) Consortium and his team Drs. Luiz Acauan and Estelle Cohen, in conjunction with Strebe’s residency at MIT supported by the Center for Art, Science & Technology (CAST).

An artistic feud (of sorts)

Earlier this year, I updated a story on Vantablack. It was the blackest black, blocking 99.8% of light when I featured it in a March 14, 2016 posting. The UK company making the announcement, Surrey NanoSystems, then laid the groundwork for an artistic feud when it granted exclusive rights to their carbon nanotube-based coating, Vantablack, to Sir Anish Kapoor mentioned here in an April 16, 2016 posting.

This exclusivity outraged some artists notably, Stuart Semple. In his first act of defiance, he created the pinkest pink. Next, came a Kickstarter campaign to fund Semple’s blackest black, which would be available to all artists except Anish Kapoor. You can read all about the pinkest pink and blackest black as per Semple in my February 21, 2019 posting. You can also get a bit of an update in an Oct. 17, 2019 Stuart Semple proffile by Berenice Baker for Verdict,

… so I managed to hire a scientist, Jemima, to work in the studio with me. She got really close to a super black, and we made our own pigment to this recipe and it was awesome, but we couldn’t afford to put it into manufacture because it cost £25,000.”

Semple launched a Kickstarter campaign and was amazed to raise half a million pounds, making it the second most-supported art Kickstarter of all time.

The ‘race to the blackest’ is well underway, with MIT researchers recently announcing a carbon nanotube-based black whose light absorption they tested by coasting a diamond. But Semple is determined that his black should be affordable by all artists and work like a paint, not only perform in laboratory conditions. He’s currently working with Jemima and two chemists to upgrade the recipe for Black 3.2.

I don’t know how Semple arrived at his blackest black. I think it’s unlikely that he achieved the result by working with carbon nanotubes since my understanding is that CNTs aren’t that easy to produce.

Finally

Interesting, eh? In just a few years scientists have progressed from achieving a 99.8% black to 99.999%. It doesn’t seem like that big a difference to me but with Solomon Woods, at the beginning of this post, making the point that our eyes are very sensitive to light, an artistic feud, and a study uncovering deep emotions, getting the blackest black is a much more artistically fraught endeavour than I had imagined.

Collider Cafe in Vancouver on December 4, 2019

I think they were tired when they (CuriosityCollider.org) came up with the title for the upcoming Collider Cafe December 2019 event. Unfortunately, the description isn’t too exciting either. On the plus side, their recent Invasive Systems Collisions Festival was pretty interesting and one of the exhibits from that festival is being featured (artist: Laara Cerman; scientist: Scott Pownell)..

Here’s more about the upcoming Collider Cafe from their November 27, 2019 announcement (received via email),

Art. Science. Analogies.

Also, CC Creative Director Char Hoyt will share highlights from our annual art-science festival Collisions Festival: Invasive Systems.

Head to the Facebook event page – let us know you are coming and share this event with others! Follow updates on Instagram via @curiositycollider or #ColliderCafe. 

Back to me, I’m still struggling with this hugely changed Word Press, which they claim is an ‘improvement’. In any case, for this second event, I decided that choosing a larger font size was superior to putting everything into a single block as I did for the Science Slam event. Please let me know if you have any opinions on the matter in the comments section.

Moving on, don’t expect Chris Dunnett’s presentation ‘Poetry of Technology’ to necessarily feature any poetry, if his website is any indication of his work. Also, I notice that Vance Williams is associated with 4D Labs at Simon Fraser University. At one time, 4D Labs was a ‘nanotechnology’ lab but at this time (November 29, 2019), it seems they are a revenue-producing group selling their materials expertise and access to their lab equipment to industry and other academic institutions. Still, Williams may feature some nanoscale work as part of his presentation.

Smartphone as augmented reality system with software from Brown University

You need to see this,

Amazing, eh? The researchers are scheduled to present this work sometime this week at the ACM Symposium on User Interface Software and Technology (UIST) being held in New Orleans, US, from October 20-23, 2019.

Here’s more about ‘Portal-ble’ in an October 16, 2019 news item on ScienceDaily,

A new software system developed by Brown University [US] researchers turns cell phones into augmented reality portals, enabling users to place virtual building blocks, furniture and other objects into real-world backdrops, and use their hands to manipulate those objects as if they were really there.

The developers hope the new system, called Portal-ble, could be a tool for artists, designers, game developers and others to experiment with augmented reality (AR). The team will present the work later this month at the ACM Symposium on User Interface Software and Technology (UIST 2019) in New Orleans. The source code for Andriod is freely available for download on the researchers’ website, and iPhone code will follow soon.

“AR is going to be a great new mode of interaction,” said Jeff Huang, an assistant professor of computer science at Brown who developed the system with his students. “We wanted to make something that made AR portable so that people could use anywhere without any bulky headsets. We also wanted people to be able to interact with the virtual world in a natural way using their hands.”

An October 16, 2019 Brown University news release (also on EurekAlert), which originated the news item, provides more detail,

Huang said the idea for Portal-ble’s “hands-on” interaction grew out of some frustration with AR apps like Pokemon GO. AR apps use smartphones to place virtual objects (like Pokemon characters) into real-world scenes, but interacting with those objects requires users to swipe on the screen.

“Swiping just wasn’t a satisfying way of interacting,” Huang said. “In the real world, we interact with objects with our hands. We turn doorknobs, pick things up and throw things. So we thought manipulating virtual objects by hand would be much more powerful than swiping. That’s what’s different about Portal-ble.”

The platform makes use of a small infrared sensor mounted on the back of a phone. The sensor tracks the position of people’s hands in relation to virtual objects, enabling users to pick objects up, turn them, stack them or drop them. It also lets people use their hands to virtually “paint” onto real-world backdrops. As a demonstration, Huang and his students used the system to paint a virtual garden into a green space on Brown’s College Hill campus.

Huang says the main technical contribution of the work was developing the right accommodations and feedback tools to enable people to interact intuitively with virtual objects.

“It turns out that picking up a virtual object is really hard if you try to apply real-world physics,” Huang said. “People try to grab in the wrong place, or they put their fingers through the objects. So we had to observe how people tried to interact with these objects and then make our system able accommodate those tendencies.”

To do that, Huang enlisted students in a class he was teaching to come up with tasks they might want to do in the AR world — stacking a set of blocks, for example. The students then asked other people to try performing those tasks using Portal-ble, while recording what people were able to do and what they couldn’t. They could then adjust the system’s physics and user interface to make interactions more successful.

“It’s a little like what happens when people draw lines in Photoshop,” Huang said. “The lines people draw are never perfect, but the program can smooth them out and make them perfectly straight. Those were the kinds of accommodations we were trying to make with these virtual objects.”

The team also added sensory feedback — visual highlights on objects and phone vibrations — to make interactions easier. Huang said he was somewhat surprised that phone vibrations helped users to interact. Users feel the vibrations in the hand they’re using to hold the phone, not in the hand that’s actually grabbing for the virtual object. Still, Huang said, vibration feedback still helped users to more successfully interact with objects.

In follow-up studies, users reported that the accommodations and feedback used by the system made tasks significantly easier, less time-consuming and more satisfying.

Huang and his students plan to continue working with Portal-ble — expanding its object library, refining interactions and developing new activities. They also hope to streamline the system to make it run entirely on a phone. Currently the infrared sensor requires an infrared sensor and external compute stick for extra processing power.

Huang hopes people will download the freely available source code and try it for themselves. 
“We really just want to put this out there and see what people do with it,” he said. “The code is on our website for people to download, edit and build off of. It will be interesting to see what people do with it.

Co-authors on the research paper were Jing Qian, Jiaju Ma, Xiangyu Li, Benjamin Attal, Haoming Lai, James Tompkin and John Hughes. The work was supported by the National Science Foundation (IIS-1552663) and by a gift from Pixar.

Art/science and a paintable diagnostic test for cancer

[downloaded from https://news.artnet.com/art-world/carbon-nanotube-cancer-paint-1638340?utm_content=from_&utm_source=Sailthru&utm_medium=email&utm_campaign=Global%20September%202%20PM&utm_term=artnet%20News%20Daily%20Newsletter%20USE%20%2830%20Day%20Engaged%20Only%29]

The artist credited with the work seen in the above, Joseph Cohen, has done something remarkable with carbon nanotubes (CNTs). Something even more remarkable than the painting as Sarah Cascone recounts in her August 30, 2019 article for artnet.com (Note: A link has been removed),

Not every artist can say that his or her work is helping in the fight against cancer. But over the past several years, Joseph Cohen has done just that, working to develop a new, high-tech paint that can be used not only on canvas, but also to detect cancers and medical conditions such as hypertension and diabetes.

Sloan Kettering Institute scientist Daniel Heller first suggested that Cohen come work at his lab after seeing the artist’s work, which is often made with pigments that incorporate diamond dust and gold, at the DeBuck Gallery in New York.

“We initially thought that in working with an artist, we would make art to shed a little light on our science for the public,” Heller told the Memorial Sloan Kettering blog. “But the collaboration actually taught us something that could help us shine a light on cancer.”

For Cohen, the project was initially intended to develop a new way of art-making. In Heller’s lab, he worked with carbon nanotubes, which Heller was already employing in cancer research, for their optical properties. “They fluoresce in the infrared spectrum,” Cohen says. “That gives artists the opportunity to create paintings in a new spectrum, with a whole new palette of colors.”

Because human eyesight is limited, we can’t actually see infrared fluorescence. But using a special short-wave infrared camera, Cohen is able to document otherwise invisible effects, revealing the carbon nanotube paint’s hidden colors.

“What you’re perceiving as a static painting is actually in motion,” Cohen says. “I’m creating paintings that exist outside of the visible experience.”

Art Supplies—and a Diagnostic Tool

That same imaging technique can be used by doctors looking for microalbuminuria, a condition that causes the kidneys to leak trace amounts of albumin into urine, which is an early sign of of several cancers, diabetes, and high blood pressure.

Cohen helped co-author a paper published this month in Nature Communications about using the nanosensor paint in litmus paper tests with patient urine samples. The study found that the paint, when viewed through infrared light, was able to reveal the presence of albumin based on changes in the paint’s fluorescence after being exposed to the urine sample.

“It’s easy to detect albumen with a dipstick if there’s a lot of levels in the urine, but that would be like looking at stage four cancer,” Cohen says. “This is early detection.”

What’s more, a nanosensor paint can be easily used around the world, even in poor areas that don’t have access to the best diagnostic technologies. Doctors may even be able to view the urine samples using an infrared imaging attachments on their smartphones.

Amazing, eh? If you have the time, do read Cascone’s article in its entirety and should your curiosity be insatiable, there’s also an August 22, 2019 posting by Jim Stallard on the Memorial Sloan Kettering Cancer Center blog,

Here’s a link to and a citation for the paper,

P.S. I’m sorry I wasn’t able to post this in a more timely fashion.

Transmissions; a multimedia installation in Vancouver, September 6 -28, 2019

Here’s a description for the multimedia installation, Transmissions, in the August 28, 2019 Georgia Straight article by Janet Smith,

Lisa Jackson is a filmmaker, but she’s never allowed that job description to limit what she creates or where and how she screens her works.

The Anishinaabe artist’s breakout piece was last year’s haunting virtual-reality animation Biidaaban: First Light. In its eerie world, one that won a Canadian Screen Award, nature has overtaken a near-empty, future Toronto, with trees growing through cracks in the sidewalks, vines enveloping skyscrapers, and people commuting by canoe.

All that and more has brought her here, to Transmissions, a 6,000-square-foot, immersive film installation that invites visitors to wander through windy coastal forests, by hauntingly empty glass towers, into soundscapes of ancient languages, and more.

Through the labyrinthine multimedia work at SFU [Simon Fraser University] Woodward’s, Jackson asks big questions—about Earth’s future, about humanity’s relationship to it, and about time and Indigeneity.

Simultaneously, she mashes up not just disciplines like film and sculpture, but concepts of science, storytelling, and linguistics [emphasis mine].

“The tag lines I’m working with now are ‘the roots of meaning’ and ‘knitting the world together’,” she explains. “In western society, we tend to hive things off into ‘That’s culture. That’s science.’ But from an Indigenous point of view, it’s all connected.”

Transmissions is split into three parts, with what Jackson describes as a beginning, a middle, and an end. Like Biidaaban, it’s also visually stunning: the artist admits she’s playing with Hollywood spectacle.

Without giving too much away—a big part of the appeal of Jackson’s work is the sense of surprise—Vancouver audiences will first enter a 48-foot-long, six-foot-wide tunnel, surrounded by projections that morph from empty urban streets to a forest and a river. Further engulfing them is a soundscape that features strong winds, while black mirrors along the floor skew perspective and play with what’s above and below ground.

“You feel out of time and space,” says Jackson, who wants to challenge western society’s linear notions of minutes and hours. “I want the audience to have a physical response and an emotional response. To me, that gets closer to the Indigenous understanding. Because the Eurocentric way is more rational, where the intellectual is put ahead of everything else.”

Viewers then enter a room, where the highly collaborative Jackson has worked with artist Alan Storey, who’s helped create Plexiglas towers that look like the ghost high-rises of an abandoned city. (Storey has also designed other components of the installation.) As audience members wander through them on foot, projections make their shadows dance on the structures. Like Biidaaban, the section hints at a postapocalyptic or posthuman world. Jackson operates in an emerging realm of Indigenous futurism.

The words “science, storytelling, and linguistics” were emphasized due to a minor problem I have with terminology. Linguistics is defined as the scientific study of language combining elements from the natural sciences, social sciences, and the humanities. I wish either Jackson or Smith had discussed the scientific element of Transmissions at more length and perhaps reconnected linguistics to science along with the physics of time and space, as well as, storytelling, film, and sculpture. It would have been helpful since it’s my understanding, Transmissions is designed to showcase all of those connections and more in ways that may not be obvious to everyone. On the plus side, perhaps the tour, which is part of this installation experience includes that information.

I have a bit .more detail (including logistics for the tours) from the SFU Events webpage for Transmissions,

TRANSMISSIONS is a three-part, 6000 square foot multimedia installation by award-winning Anishinaabe filmmaker and artist Lisa Jackson. It extends her investigation into the connections between land, language, and people, most recently with her virtual reality work Biidaaban: First Light.

Projections, sculpture, and film combine to create urban and natural landscapes that are eerie and beautiful, familiar and foreign, concrete and magical. Past and future collide in a visceral and thought-provoking journey that questions our current moment and opens up the complexity of thought systems embedded in Indigenous languages. Radically different from European languages, they embody sets of relationships to the land, to each other, and to time itself.

Transmissions invites us to untether from our day-to-day world and imagine a possible future. It provides a platform to activate and cross-pollinate knowledge systems, from science to storytelling, ecology to linguistics, art to commerce. To begin conversations, to listen deeply, to engage varied perspectives and expertise, to knit the world together and find our place within the circle of all our relations.

Her Story: Canadian Women Scientists (short film subjects); Sept. 13 – 14, 2019

Curiosity Collider, producer of art/science events in Vancouver, is presenting a film series featuring Canadian women scientists, according to an August 27 ,2019 press release (received via email),

Her Story: Canadian Women Scientists,” a film series dedicated to sharing the stories of Canadian women scientists, will premiere on September 13th and 14th at the Annex theatre. Four pairs of local filmmakers and Canadian women scientists collaborated to create 5-6 minute videos; for each film in the series, a scientist tells her own story, interwoven with the story of an inspiring Canadian women scientist who came before her in her field of study.

Produced by Vancouver-based non-profit organization Curiosity Collider, this project was developed to address the lack of storytelling videos showcasing remarkable women scientists and their work available via popular online platforms. “Her Story reveals the lives of women working in science,” said Larissa Blokhuis, curator for Her Story. “This project acts as a beacon to girls and women who want to see themselves in the scientific community. The intergenerational nature of the project highlights the fact that women have always worked in and contributed to science.

This sentiment was reflected by Samantha Baglot as well, a PhD student in neuroscience who collaborated with filmmaker/science cartoonist Armin Mortazavi in Her Story. “It is empowering to share stories of previous Canadian female scientists… it is empowering for myself as a current female scientist to learn about other stories of success, and gain perspective of how these women fought through various hardships and inequality.”

When asked why seeing better representation of women in scientific work is important, artist/filmmaker Michael Markowsky shared his thoughts. “It’s important for women — and their male allies — to question and push back against these perceived social norms, and to occupy space which rightfully belongs to them.” In fact, his wife just gave birth to their first child, a daughter; “It’s personally very important to me that she has strong female role models to look up to.” His film will feature collaborating scientist Jade Shiller, and Kathleen Conlan – who was named one of Canada’s greatest explorers by Canadian Geographic in 2015.

Other participating filmmakers and collaborating scientists include: Leslie Kennah (Filmmaker), Kimberly Girling (scientist, Research and Policy Director at Evidence for Democracy), Lucas Kavanagh and Jesse Lupini (Filmmakers, Avocado Video), and Jessica Pilarczyk (SFU Assistant Professor, Department of Earth Sciences).

This film series is supported by Westcoast Women in Engineering, Science and Technology (WWEST) and Eng.Cite. The venue for the events is provided by Vancouver Civic Theatres.

Event Information

Screening events will be hosted at Annex (823 Seymour St, Vancouver) on September 13th and 14th [2019]. Events will also include a talkback with filmmakers and collab scientists on the 13th, and a panel discussion on representations of women in science and culture on the 14th.

ETA September 4, 2019 at 1607 hours PDT: That last comment is even truer than I knew when I published earlier. I missed a Vancouver event, Maker Faire Vancouver will be hosted at Science World on Saturday, September 14. Here’s a little more about it from a Sept. 3, 2019 at Science World at Telus Science World blog posting,

Earlier last month [August 2019?], surgeons at St Paul’s Hospital performed an ankle replacement for a Cloverdale resident using a 3D printed bone. The first procedure of its kind in Western Canada, it saved the patient all of his ten toes — something doctors had originally decided to amputate due to the severity of the motorcycle accident.

Maker Faire Vancouver Co-producer, John Biehler, may not be using his 3D printer for medical breakthroughs, but he does see a subtle connection between his home 3D printer and the Health Canada-approved bone.

“I got into 3D printing to make fun stuff and gadgets,” John says of the box-sized machine that started as a hobby and turned into a side business. “But the fact that the very same technology can have life-changing and life-saving applications is amazing.”

When John showed up to Maker Faire Vancouver seven years ago, opportunities to access this hobby were limited. Armed with a 3D printer he had just finished assembling the night before, John was hoping to meet others in the community with similar interests to build, experiment and create. Much like the increase in accessibility to these portable machines has changed over the years—with universities, libraries and makerspaces making them readily available alongside CNC Machines, laser cutters and more — John says the excitement around crafting and tinkering has skyrocketed as well.

“The kind of technology that inspires people to print a bone or spinal insert all starts at ground zero in places like a Maker Faire where people get exposed to STEAM,” John says …

… From 3D printing enthusiasts like John to knitters, metal artists and roboticists, this full one-day event [Maker Faire Vancouver on Saturday, September 14, 2019] will facilitate cross-pollination between hobbyists, small businesses, artists and tinkerers. Described as part science fair, part county fair and part something entirely new, Maker Faire Vancouver hopes to facilitate discovery and what John calls “pure joy moments.”

Hopefully that’s it.

Computers made of gold embroidery and an Organic Bioelectronics conference (ORBITALY) in Naples, Italy

Spend enough time reading about emerging technologies and, at some point, you will find yourself questioning some of your dearly held beliefs. It gives a whole new meaning to term, mind altering (also, mind blowing or mind expanding), which in the 1960s was used to refer to the effects of LSD and other hallucinogens. Today <September 1, 2019 (Labour Day in Canada and elsewhere), I have two news bits that could be considered mind expanding, sans hallucinogens.

Gold-embroidered computers

The Embroidered Computer. Artists: Irene Posch and Ebru Kurbak .[downloaded from http://www.ireneposch.net/the-embroidered-computer/]

If you look closely, you’ll see the beads shift position and that’s how the ones and zeroes make themselves known on this embroidered computer. An August 23, 2019 article (updated from a March 8, 2019 article) on the CBC’s (Canadian Broadcasting Corporation) Radio, Spark programme web space, provides insight into the work,

A beautiful ’embroidered computer’ may explode our categories of what computers are supposed to look like.

After all, we may think the design of a computer is permanent, but what a computer ‘looks like’ depends a lot on what era it’s from.

“We use gold-coloured copper wire to form a coil, in a donut shape” Posch told Spark host Nora Young. “Then we have a magnetic bead that sits in the middle of this coil, and when this coil is [connected to] power, the magnetic bead is either attracted or pushed away….

Depending on how we power… the embroidered coil, we can direct the magnetic bead in different positions.”

More gold embroidery on top of the bead will flip one way or another, based on the bead [above].

The process is analogous to the zeros and ones of computation.

As well as being an artist, Posch is a professor at the University for Art and Industrial Design in Linz, Austria. Much of her work and research uses textile art to explore digital technology.

In this case, it’s not like Irene expects people to start doing today’s heavy-duty computing on a two-metre-long, eight-bit golden embroidered fabric computer. But The Embroidered Computer project opens up space to question the design of computers in particular, but also our technologies in general

“I understand The Embroidered Computer as an alternative, as an example, but also a critique of what we assume a computer to be today, and how it technically could be different,” Posch said. “If this is actually what we want is a whole different question, but I think it’s interesting to propose an alternative.”

Bringing together textiles and electronics, which are normally seen as worlds apart, can bring new insights. “Going into the history of computing we very soon become aware that they’re not that apart as we sometimes think they are, if you think of the Jacquard weaving loom as one of the predecessors of computing today.”

You can find our more about the artists (Ebru Kurkak here) and (Irene Posch here). Finally, you can hear the Spark radio interview with Irene Posch here.

ORBITALY 2019

I don’t have a lot of information about this event but what I do have looks intriguing. From the ORBITALY 2019 conference home page,

OrBItaly (Organic BIoelectronics Italy) is an international conference, organized by the Italian Scientific Community and attended by scientists of the highest reputation, dedicated to the most recent results in the field of bioelectronics, with a particular focus on the employment of organic materials.

OrBItaly has attracted in the years a growing interest by scientists coming from all over the world. The 2019 edition is the fifth one of this cross-disciplinary conference, and will be held in Naples, on October 21st-23rd, 2019, at the Congress Center of the University Federico II

This year the conference will be preceded by the first edition of the Graduate School in Organic Bioelectronics, that will be held at the Congress Center of the University of Naples Federico II in Naples (Italy), on October 20th, 2019. The school is mainly targeted to PhD students, post-docs and young researchers as well as to senior scientists and industry-oriented researchers, giving them the opportunity to attend an overview of the latest advances in the fields of organic bioelectronics presented by leading scientists of the highest international repute. Invited lecturers will provide highly stimulating lessons at advanced levels in their own field of research, and closely interact with the attendees during platform discussions, outreach events and informal meetings.

Café Scientifique: From tadpole tails to diagnosing disease – the evolution of protease research, August 27, 2019

From an August 14, 2019 Café Scientifique announcement (received via email),

Our next café will happen on Tuesday, August 27th at 7:30pm in the back room at Yagger’s Downtown (433 W Pender). Our speaker for the evening will be  Dr. Georgina Butler from the Centre for Blood Research at UBC [University of British Columbia].


From tadpole tails to diagnosing disease – the evolution of protease research  
 
Proteases are enzymes that cut other proteins. Humans have 560 different proteases – why so many? what are they doing? We know that too much protease activity can be detrimental in diseases such as cancer and arthritis, but failed efforts to stop cancer spread by blocking proteases has contributed to the realization that some cuts are essential. In the era of “big data”, at UBC we have developed new techniques (degradomics) to study proteases on a global scale to determine what they really do in health and disease. Hopefully this information will enable us to identify new drug targets as well as novel biomarkers to diagnose or monitor disease.

Dr. Butler completed her undergraduate degree in Biochemistry (with Studies in Italy) at the University of Kent at Canterbury, and her PhD in Biochemistry at the University of Leicester in the UK. She came to UBC as a Wellcome Trust Travelling Fellow in 1999 for 2 years. Still here, she is a Research Associate at the Centre for Blood Research and in Oral, Biological and Medical Sciences at UBC, where she studies novel roles of proteases in health and disease. 

We hope to see you there!
