Symbiosis (science education initiative) in British Columbia (Canada)

Is it STEM (science, technology, engineering, and mathematics) or is it STEAM (science, technology, engineering, arts, and mathematics)?

It’s STEAM as least as far as Dr. Scott Sampson is concerned. In his July 6, 2018 Creative Mornings Vancouver talk in Vancouver (British Columbia, Canada) he mentioned a major science education/outreach initiative taking place in the province of British Columbia (BC) but intended for all of Canada, Symbiosis There was some momentary confusion as Sampson’s slide deck identified it as a STEM initiative. Sampson verbally added the ‘A’ for arts and henceforth described it as a STEAM initiative. (Part of the difficulty is that many institutions have used the term STEM and only recently come to the realization they might want to add ‘art’ leading to confusion in Canada and the US, if nowhere else, as old materials require updating. Actually, I vote for adding the humanities too so that we can have SHTEAM.)

You’ll notice, should you visit the Symbiosis website, that the STEM/STEAM confusion extends further than Sampson’s slide deck.

Sampson,  “a dinosaur paleontologist, science communicator, and passionate advocate for reimagining cities as places where people and nature thrive, serves (since 2016) as president and CEO of Science World British Columbia” or as they’re known on their website:  Science World at TELUS World of Science. Unwieldy, eh?

The STEM/STEAM announcement

None of us in the Creative Mornings crowd had heard of Symbiosis or Scott Sampson for that matter (apparently, he’s a huge star among the preschool set due to his work on the PBS [US Public Broadcasting Service] children’s show ‘Dinosaur Train’). Regardless, it was good to hear  of this effort although my efforts to learn more about it have been a bit frustrated.

First, here’s what I found: a May 25, 2017 Science World media release (PDF) about Symbiosis,

Science World Introduces Symbiosis
A First-of Its-Kind [sic] Learning Ecosystem forCanada

We live in a time of unprecedented change. High-tech innovations are rapidly transforming 21st century societies and the Canadian marketplace is increasingly dominated by novel, knowledge-based jobs requiring high levels of literacy in science, technology, engineering and math (STEM). Failing to prepare the next generation to be STEM literate threatens the health of our youth, the economy and the places we live. STEM literacy needs to be integrated into the broader context of what it means to be a 21st century citizen. Also important is inclusion of an extra letter, “A,” for art and design, resulting in STEAM. The idea behind Symbiosis is to make STEAM learning accessible across Canada.

Every major Canadian city hosts dozens to hundreds of organizations that engage children and youth in STEAM learning. Yet, for the most part, these organizations operate in isolation. The result is that a huge proportion of Canadian youth, particularly in First Nations and other underserved communities, are not receiving quality STEAM learning opportunities.

In order to address this pressing need, Science World British Columbia (scienceworld.ca) is spearheading the creation of Symbiosis, a deeply collaborative STEAM learning ecosystem. Driven by a diverse network of cross-sector partners, Symbiosis will become a vibrant model for scaling the kinds of learning and careers needed in a knowledge-based economy.

Today [May 25, 2017], Science World is proud to announce that Symbiosis has been selected by STEM Learning Ecosystems, a US-based organization, to formally join a growing movement. In just two years, the STEM Learning Ecosystems  initiative has become a thriving network of hundreds of organizations and thousands of individuals, joined in regional partnerships with the objective of collaborating in new and creative ways to increase equity, quality, and STEM learning outcomes for all youth. Symbiosis will be the first member of this initiative outside the United States.

Symbiosis was selected to become part of the STEM Learning Ecosystem initiative because of a demonstrated [emphasis mine] commitment to cross-sector collaborations in schools and beyond the classroom. As STEM Ecosystems evolve, students will be able to connect what they’ve learned, in and out of school, with real-world, community-based opportunities.

I wonder how Symbiosis demonstrated their commitment. Their website doesn’t seem to have existed prior to 2018 and there’s no information there about any prior activities.

A very Canadian sigh

I checked the STEM Learning Ecosystems website for its Press Room and found a couple of illuminating press releases. Here’s how the addition of Symbiosis was described in the May 25, 2017 press release,

The 17 incoming ecosystem communities were selected because they demonstrate a commitment to cross-sector collaborations in schools and beyond the classroom—in afterschool and summer programs, at home, with local business and industry partners, and in science centers, libraries and other places both virtual and physical. As STEM Ecosystems evolve, students will be able to connect what is learned in and out of school with real-world opportunities.

“It makes complete sense to collaborate with like-minded regions and organizations,” said Matthew Felan of the Great Lakes Bay Regional Alliance STEM Initiative, one of the founding Ecosystems. “STEM Ecosystems provides technical assistance and infrastructure support so that we are able to tailor quality STEM learning opportunities to the specific needs of our region in Michigan while leveraging the experience of similar alliances across the nation.”

The following ecosystem communities were selected to become part of this [US} national STEM Learning Ecosystem:

  • Arizona: Flagstaff STEM Learning Ecosystem
  • California: Region 5 STEAM in Expanded Learning Ecosystem (San Benito, Santa Clara, Santa Cruz, Monterey Counties)
  • Louisiana: Baton Rouge STEM Learning Network
  • Massachusetts: Cape Cod Regional STEM Network
  • Michigan: Michigan STEM Partnership / Southeast Michigan STEM Alliance
  • Missouri: Louis Regional STEM Learning Ecosystem
  • New Jersey: Delran STEM Ecosystem Alliance (Burlington County)
  • New Jersey: Newark STEAM Coalition
  • New York: WNY STEM (Western New York State)
  • New York: North Country STEM Network (seven counties of Northern New York State)
  • Ohio: Upper Ohio Valley STEM Cooperative
  • Ohio: STEM Works East Central Ohio
  • Oklahoma: Mayes County STEM Alliance
  • Pennsylvania: Bucks, Chester, Delaware, Montgomery STEM Learning Ecosystem
  • Washington: The Washington STEM Network
  • Wisconsin: Greater Green Bay STEM Network
  • Canada: Symbiosis, British Columbia, Canada

Yes, somehow a Canadian initiative becomes another US regional community in their national ecosystem.

Then, they made everything better a year later in a May 29, 2018 press release,

New STEM Learning Ecosystems in the United States are:

  • California: East Bay STEM Network
  • Georgia: Atlanta STEAM Learning Ecosystem
  • Hawaii: Hawai’iloa ecosySTEM Cabinet
  • Illinois: South Suburban STEAM Network
  • Kentucky: Southeastern Kentucky STEM Ecosystem
  • Massachusetts: MetroWest STEM Education Network
  • New York: Greater Southern Tier STEM Learning Network
  • North Carolina: STEM SENC (Southeastern North Carolina)
  • North Dakota: North Dakota STEM Ecosystem
  • Texas: SA/Bexar STEM/STEAM Ecosystem

The growing global Community of Practice has added: [emphasis mine]

  • Kenya: Kenya National STEM Learning Ecosystem
  • México: Alianza Para Promover la Educación en STEM (APP STEM)

Are Americans still having fantasies about ‘manifest destiny’? For those unfamiliar with the ‘doctrine’,

In the 19th century, manifest destiny was a widely held belief in the United States that its settlers were destined to expand across North America.  …

They seem to have given up on Mexico but the dream of acquiring Canadian territory rears its head from time to time. Specifically, it happens when Quebec holds a referendum (the last one was in 1995) on whether or not it wishes to remain part of the Canadian confederation. After the last referendum, I’d hoped that was the end of ‘manifest destiny’ but it seems these 21st Century-oriented STEM Learning Ecosystems people have yet to give up a 19th century fantasy. (sigh)

What is Symbiosis?

For anyone interested in the definition of the word, from Wordnik,

symbiosis

As for this BC-based organization, Symbiosis, which they hope will influence Canadian STEAM efforts and learning as a whole, I don’t have much. From the Symbiosis About Us webpage,

A learning ecosystem is an interconnected web of learning opportunities that encompasses formal education to community settings such as out-of-school care, summer programs, science centres and museums, and experiences at home.

​In May 2017, Symbiosis was selected by STEM Learning Ecosystems, a US-based organization, to formally join a growing movement. As the first member of this initiative outside the United States, Symbiosis has demonstrated a commitment to cross-sector collaborations in schools and beyond the classroom. As Symbiosis evolves, students will be able to connect what they’ve learned, in and out of school, with real-world, community-based opportunities.

  • Is research-based, data-driven
  • Shares stories of success—stories of people/role models using STEAM and critical thinking to make a difference
  • Provides a  variety of access points that are available to all learners

I was looking for more concrete information such as:

  • what is your budget?
  • which organizations are partners?
  • where do you get your funding?
  • what have you done so far?

I did get an answer to my last question by going to the Symbiosis news webpage where I found these,

We’re hiring!

Make of that what you will. Also, there is a 2018 copyright notice (at the bottom of the webpages) but no copyright owner is listed.

There is some Symbiosis information

A magazine known as BC Business (!) offers some details in a May 11, 2018 opinion piece, Note: Links have been removed,

… Increasingly, the Canadian marketplace is dominated by novel, knowledge-based jobs requiring high levels of literacy in STEM (science, technology, engineering and math). Here in B.C., the tech sector now employs over 100,000 people, about 5 percent of the province’s total workforce. As the knowledge economy grows, these numbers will rise dramatically.

Yet technology-driven businesses are already struggling to fill many roles that require literacy in STEM. …

Today, STEM education in North America and elsewhere is struggling. One study found that 60 percent of students who enter high school interested in STEM fields change their minds by graduation. Lacking mentoring, students, especially girls, tend to lose interest in STEM. [emphasis mine]Today, only 22 percent of Canadian STEM jobs are held by women. Failing to prepare the next generation to be STEM-literate threatens the prospects of our youth, our economy and the places we live.

More and more, education is no longer confined to classrooms. … To kickstart this future, a “STEM learning ecosystem” movement has emerged in the United States, grounded in deeply collaborative, cross-sector networks of learning opportunities.

Symbiosis will concentrate on a trio of impacts:

1) Dramatically increasing the number of qualified STEM mentors in B.C.—from teachers and scientists to technologists and entrepreneurs;

2) Connecting this diversity of mentors with children and youth through networked opportunities, from classroom visits and on-site shadowing to volunteering and internships; and

3) Creating a digital hub that interweaves communities, hosts a library of resources and extends learning through virtual offerings. [emphases mine]

Science World British Columbia is spearheading Symbiosis, and organizations from many sectors have expressed strong interest in collaborating—among them K-12 education, higher education, industry, government and non-profits. Several of these organizations are founding members of the BC Science Charter, which formed in 2013.

Symbiosis will launch in fall of 2018 with two pilot communities: East Vancouver and Prince George. …

As for why students tend to lose interest in STEM, there’s a rather interesting longitudinal study taking place in the UK which attempts to answer at least some of that question. I first wrote about the ASPIRES study in a January 31, 2012 posting: Science attitude kicks in by 10 years old. This was based on preliminary data and it seemed to be confirmed by an unrelated US study of high school students also mentioned in that posting (scroll down about 40% of the way).

In short, both studies suggested that children are quite to open to science but when it comes time to think about careers, they tend to ‘aspire’ to what they see amongst family and friends. I don’t see that kind of thinking reflected in any of the information I’ve been able to find about Symbiosis and it was not present in Sampson’s, Creative Mornings talk.

However, I noted during Sampson’s talk that he mentioned his father, a professor of psychology at the University of British Columbia and how he had based his career expectations on his father’s career. (Sampson is from Vancouver originally.) Sampson, like his father, was at one point a professor of ‘science’ at a university.

Perhaps one day someone from Symbiosis will look into the ASPIRE studies or even read my blog 🙂

You can find the latest about what is now called the ASPIRES 2 study here. (I will try to post my own update to the ASPIRES projects in the near future).

Best hopes

I am happy to see Symbiosis arrive on the scene and I wish all the best for the initiative. I am less concerned than the BC Business folks about supplying employers with the kind of employees they want to hire and hopeful that Symbiosis will attract not just the students, educators, mentors, and scientists to whom they are appealing but will cast a wider net to include philosophers, car mechanics, hairdressers, poets, visual artists, farmers, chefs, and others in a ‘pursuit of wonder’.

Aside: I was introduced to the phrase ‘pursuit of wonder’ by a friend who sent me a link to José Teodoro’s May 29, 2018 interview with Canadian filmmaker, Peter Mettler for the Brick. Mettler discusses his film about the Northern Lights and the technical challenges he met along the way.

Getting chipped

A January 23, 2018 article by John Converse Townsend for Fast Company highlights the author’s experience of ‘getting chipped’ in Wisconsin (US),

I have an RFID, or radio frequency ID, microchip implanted in my hand. Now with a wave, I can unlock doors, fire off texts, login to my computer, and even make credit card payments.

There are others like me: The majority of employees at the Wisconsin tech company Three Square Market (or 32M) have RFID implants, too. Last summer, with the help of Andy “Gonzo” Whitehead, a local body piercer with 17 years of experience, the company hosted a “chipping party” for employees who’d volunteered to test the technology in the workplace.

“We first presented the concept of being chipped to the employees, thinking we might get a few people interested,” CEO [Chief Executive Officer] Todd Westby, who has implants in both hands, told me. “Literally out of the box, we had 40 people out of close to 90 that were here that said, within 10 minutes, ‘I would like to be chipped.’”

Westby’s left hand can get him into the office, make phone calls, and stores his living will and drivers license information, while the chip in his right hand is using for testing new applications. (The CEO’s entire family is chipped, too.) Other employees said they have bitcoin wallets and photos stored on their devices.

The legendary Gonzo Whitehead was waiting for me when I arrived at Three Square Market HQ, located in quiet River Falls, 40 minutes east of Minneapolis. The minutes leading up to the big moment were a bit nervy, after seeing the size of the needle (it’s huge), but the experience was easier than I could have imagined. The RFID chip is the size of a grain of basmati rice, but the pain wasn’t so bad–comparable to a bee sting, and maybe less so. I experienced a bit of bruising afterward (no bleeding), and today the last remaining mark of trauma is a tiny, fading scar between my thumb and index finger. Unless you were looking for it, the chip resting under my skin is invisible.

Truth is, the applications for RFID implants are pretty cool. But right now, they’re also limited. Without a near-field communication (NFC) writer/reader, which powers on a “passive” RFID chip to write and read information to the device’s memory, an implant isn’t of much use. But that’s mostly a hardware issue. As NFC technology becomes available, which is increasingly everywhere thanks to Samsung Pay and Apple Pay and new contactless “tap-and-go” credit cards, the possibilities become limitless. [emphasis mine]

Health and privacy?

Townsend does cover a few possible downsides to the ‘limitless possibilities’ offered by RFID’s combined with NFC technology,

From a health perspective, the RFID implants are biologically safe–not so different from birth control implants [emphasis mine]. [US Food and Drug Administration] FDA-sanctioned for use in humans since 2004, the chips neither trigger metal detectors nor disrupt [magnetic resonance imaging] MRIs, and their glass casings hold up to pressure testing, whether that’s being dropped from a rooftop or being run over by a pickup truck.

The privacy side of things is a bit more complicated, but the undeniable reality is that privacy isn’t as prized as we’d like to think [emphasis mine]. It’s already a regular concession to convenience.

“Your information’s for sale every day,” McMullen [Patrick McMullen, president, Three Square Market] says. “Thirty-four billion avenues exist for your information to travel down every single day, whether you’re checking Facebook, checking out at the supermarket, driving your car . . . your information’s everywhere.

Townsend may not be fully up-to-date on the subject of birth control implants. I think ‘safeish’ might be a better description in light of this news of almost two years ago (from a March 1, 2016 news item on CBS [Columbia Broadcasting Service] News [online]), Note: Links have been removed,

[US] Federal health regulators plan to warn consumers more strongly about Essure, a contraceptive implant that has drawn thousands of complaints from women reporting chronic pain, bleeding and other health problems.

The Food and Drug Administration announced Monday it would add a boxed warning — its most serious type — to alert doctors and patients to problems reported with the nickel-titanium implant.

But the FDA stopped short of removing the device from the market, a step favored by many women who have petitioned the agency in the last year. Instead, the agency is requiring manufacturer Bayer to conduct studies of the device to further assess its risks in different groups of women.

The FDA is requiring Bayer to conduct a study of 2,000 patients comparing problems like unplanned pregnancy and pelvic pain between patients getting Essure and those receiving traditional “tube tying” surgery. Agency officials said they have reviewed more than 600 reports of women becoming pregnant after receiving Essure. Women are supposed to get a test after three months to make sure Essure is working appropriately, but the agency noted some women do not follow-up for the test.

FDA officials acknowledged the proposed study would take years to complete, but said Bayer would be expected to submit interim results by mid-2017.

According to a Sept. 25, 2017 article by Kerri O’Brien for WRIC.com, Bayer had suspended sales of their device in all countries except the US,

Bayer, the manufacturer of Essure, has announced it’s halting sales of Essure in all countries outside of the U.S. In a statement, Bayer told 8News it’s due to a lack of interest in the product outside of the U.S.

“Bayer made a commercial decision this Spring to discontinue the distribution of Essure® outside of the U.S. where there is not as much patient interest in permanent birth control,” the statement read.

The move also comes after the European Union suspended sales of the device. The suspension was prompted by the National Standards Authority of Ireland declining to renew Essure’s CE marketing. “CE,” according to the European Commission website signifies products sold in the EEA that has been assessed to meet “high safety, health, and environmental protection requirements.”

These excerpts are about the Essure birth control implant. Perhaps others are safer? That noted, it does seem that Townsend was a bit dismissive of safety concerns.

As for privacy, he does investigate further to discover this,

As technology evolves and becomes more sophisticated, the methods to break it also evolve and get more sophisticated, says D.C.-based privacy expert Michelle De Mooy. Even so, McMullen believes that our personal information is safer in our hand than in our wallets. He  says the smartphone you touch 2,500 times a day does 100 times more reporting of data than does an RFID implant, plus the chip can save you from pickpockets and avoid credit card skimmers altogether.

Well, the first sentence suggests some caution. As for De Mooy, there’s this from her profile page on the Center for Democracy and Technology website (Note: A link has been removed),

Michelle De Mooy is Director of the Privacy & Data Project at the Center for Democracy & Technology. She advocates for data privacy rights and protections in legislation and regulation, works closely with industry and other stakeholders to investigate good data practices and controls, as well as identifying and researching emerging technology that impacts personal privacy. She leads CDT’s health privacy work, chairing the Health Privacy Working Group and focusing on the intersection between individual privacy, health information and technology. Michelle’s current research is focused on ethical and privacy-aware internal research and development in wearables, the application of data analytics to health information found on non-traditional platforms, like social media, and the growing market for genetic data. She has testified before Congress on health policy, spoken about native advertising at the Federal Trade Commission, and written about employee wellness programs for US News & World Report’s “Policy Dose” blog. Michelle is a frequent media contributor, appearing in the New York Times, the Guardian, the Wall Street Journal, Vice, and the Los Angeles Times, as well as on The Today Show, Voice of America, and Government Matters TV programs.

Ethics anyone?

Townsend does raise some ethical issues (Note: A link has been removed),

… Word from CEO Todd Westby is that parents in Wisconsin have been asking whether (and when) they can have their children implanted with GPS-enabled devices (which, incidentally, is the subject of the “Arkangel” episode in the new season of Black Mirror [US television programme]). But that, of course, raises ethical questions: What if a kid refused to be chipped? What if they never knew?

Final comments on implanted RFID chips and bodyhacking

It doesn’t seem that implantable chips have changed much since I first wrote about them in a May 27, 2010 posting titled: Researcher infects self with virus.  In that instance, Dr Mark Gasson, a researcher at the University of Reading. introduced a virus into a computer chip implanted in his body.

Of course since 2010, there are additional implantable items such as computer chips and more making their way into our bodies and it doesn’t seem to be much public discussion (other than in popular culture) about the implications.

Presumably, there are policy makers tracking these developments. I have to wonder if the technology gurus will continue to tout these technologies as already here or having made such inroads that we (the public) are presented with a fait accompli with the policy makers following behind.

Development of US plant to produce cellulosic nanomaterials announced again or is this a new one?

There’s a new announcement from the Secretary of the US Department of Agriculture (USDA) about building a commercial production plant in Wisconsin for producing cellulosic nanomaterials that greatly resembles an earlier announcement in 2012. Let’s start with the new announcement, from the Dec. 11, 2013 USDA press release (h/t AgriPulse Dec. 11, 2013 news item),

U.S. Department of Agriculture (USDA) Secretary Tom Vilsack today announced a public-private partnership to rapidly advance the development of the first U.S. commercial facility producing cellulosic nanomaterial, a wood fiber broken down to the nanoscale. The partnership is between the U.S. Endowment for Forestry and Communities (Endowment) and the U.S. Forest Service.

“We believe in the potential of wood- based nanotechnology to strengthen rural America by creating sustainable jobs and adding timber value while also creating conservation opportunities in working forests,” said Vilsack. “This public- private partnership will develop high-tech outputs from the forest products sector, and promote the invention of renewable products that have substantial environmental benefits.”

The three-year partnership will promote cellulosic nanomaterial as a commercially viable enterprise by building on work done by the Forest Products Laboratory in Madison, Wis. The partnership seeks to overcome technical barriers to large- scale wood-based nanotechnology processing, while filling gaps in the science and technology that are needed for commercialization. Initial funding comes from the Endowment and the Forest Service. The partnership is currently seeking additional public and private sector funding.

Together with partners, this new venture will:

  • Emphasize the potential of wood- based nanotechnology for the economy and the environment.
  • Overcome technical barriers to commercialization of wood- based nanotechnology.
  • Demonstrate commitment to creating high paying jobs in rural America through value- added manufacturing and high value products.
  • Showcase the commitment of USDA and the Forest Service to innovation.

The previous announcement which I covered in my July 27, 2012 posting has some similarities, although they were announcing the expected construction of a pilot plant for a specific forest-derived cellulosic nanomaterial,,

According to the July 25, 2012 article by Rick Barrett originally published by Milwaukee Journal Sentinel McClatchy-Tribune Information Services) on the equities.com website,

The U.S. Forest Products Laboratory, in Madison, says it’s opening a $1.7 million pilot plant that will support an emerging market for wood products derived from nanotechnology.

…The pilot plant will supply nanocrystals to companies and universities that want to make materials from them or conduct their own experiments. For now, at least, it will employ just one person.

But while the Forest Products Laboratory wants to foster the technology, it doesn’t want to compete with businesses interested in producing the materials.

“We are part of the federal government, so we cannot compete against commercial companies. So if someone comes in and starts making these materials on a commercial level, we will have to get out of it,” Rudie said. That’s why, he added, the program has bought only equipment it can use for other purposes.

At a guess I’d say plans were changed (to my knowledge there’ve been no announcements about the opening of a pilot plant) and they decided that a commercial plant in a private/public partnership would be the way to go. I notice they’re very careful to use the term cellulosic nanomaterials, which suggests they will be producing not just the crystals mentioned in the 2012 story but fibrils and more.

On the Canadian side of things,, Alberta gave its pilot cellulose nanocrystal (CNC, aka, nanocrystalline cellulose [NCC]) plant a soft launch in Sept. 2013, as per my Nov. 19, 2013 posting,  and Quebec’s CelluForce plant (a  Domtar/FPInnovations partnership [private/public]) has a stockpile of the crystals and is, to my knowledge (my Oct. 3, 2013 posting), is not producing any additional material.

 

NanoForArt in Mexico

Mexico recently hosted (Feb. 7 – 8, 2013) a pair of conferences focused on nanotechnology and art conservation. The country is part of an international consortium in the European Commision’s Seventh Framework Programme (FP7), NanoForArt project. Before mentioning the conference, here’s a little information about the NanoForArt project from its homepage,

The main objective of the NANOFORART proposal is the development and experimentation of new nano-materials and responsive systems for the conservation and preservation of movable and immovable artworks. [emphasis mine]

While the progress in material science has generated sophisticated nanostructured materials, conservation of cultural heritage is still mainly based on traditional methods and conventional materials that often lack the necessary  compatibility with the original artworks and a durable performance in responding to the changes of natural environment and man-made activities.

The main challenge of NANOFORART is the combination of sophisticated functional materials arising from the recent developments in nano-science/technology with innovative techniques in the restoration and preventive conservation of works of art, with unprecedented efficiency.

Immovable artworks tend to be things like cave art, frescoes, and other forms of wall and rock art. The Feb. 2013 conferences in Mexico as per a Feb. 27, 2013 Agencia EFE news item on the Global Post website featured (Note: Links have been removed),

Baglioni [Piero Baglioni, a researcher and professor at the University of Florence] and Dr. Rodorico Giorgi, also of the University of Florence, traveled to Mexico earlier this month to preside over a conference on Nanotechnology applied to cultural heritage: wall paintings/cellulose, INAH [Instituto Nacional de Antropología e Historia] said.

The project includes specialists from Italy, Spain, Britain, France, Denmark, the Czech Republic, Germany,  Slovenia and Mexico and is coordinated by the CSGI center [Center for Colloids and Surface Science] at the University of Florence.

NANONFORART is set to conclude in December 2014 with the “validation of the technology and the methods developed, as well as training activities,” INAH said.

Until now, preservation of cultural treasures has been carried out using conventional materials that are often incompatible with the works and can, over time, alter the appearance of the object.

Baglioni has worked with INAH personnel to clean and restore pre-Columbian murals at the Cacaxtla, Cholula, Tlatelolco, Mayapan, El Tajin, Monte Alban and Teotihuacan sites.

I have mentioned Baglioni’s work in Mexico previously in a Sept. 20, 2010 posting about  some work at La Antigua Ciudad Maya de Calakmul, an archaeological site which is located in the Campeche state.

Unfortunately, there aren’t too many details about the conferences, the Feb. 7, 2013 conference sported the previously noted title (in the Agencia EFE news item), Nanotechnology Applied to Cultural Heritage: Wall Paintings/Cellulose, and the Feb. 8, 2013 conference was titled, Nanotechnology for the Cleaning of Cultural Heritage.

There’s more information about nanotechnology aspects on the NanoForArt Overall page (Note: Links have been removed),

The work plan will start with design and formulation of nanostructured systems with special functionalities (WP1) such as deacidification of movable artworks (paper, parchment, canvas, leather), cleaning of movable artworks (paper, parchment, canvas paintings), protection of movable artworks (paper, canvas), consolidation of immovable artworks (wall-paintings, plaster and stones), and cleaning of immovable artworks (wallpaintings, plaster and stones). These systems, whose formulation will be optimized according to their functions, will include microemulsions, micellar solutions, gels and dispersions of different kinds of nanoparticles. A physico-chemical characterization of the developed materals (WP2) will constantly support the formulation activity. This will allow to understand and control the nature of interaction mechanisms between these nanostructures and the target substances/supports.

Assessment of the applicability of materials (WP3) will start in the second half of the first year. In this phase the up-scale of the technologies from the laboratory to the market level will be tackled. All the partners will interact in order to clarify and merge the priority from all the points of view. Evaluation of possible human health effects and environmental impacts of developed nanomaterials for restoration (WP7) will also start in the second half of the first year. Special emphasis will be given to potential hazardousness of nanoparticles used for design and formulation of nanostructured systems, as well as environmental impacts associated with the use of these nano-based products.

Nanotechnology developed by NANOFORART will aim also to significantly reduce the use of harmful solvents, as well as to introduce new environmentally friendly nanomaterials. Once the applicability and safety of the developed materials will be assessed, the development of industry process (WP4, WP5) will start in order to transfer technology on the market by the standardization of the applicative protocols and production of the nanomaterials on medium and large scale. Small and Medium Enterprise (SME) partners will have their main competence in this phase, that should start at the beginning of the second year. Safety and health risks of the industry processes will be also assessed. At the end of the first year, a study of the long-term behavior of the products and of the treated works of art (WP6) will be started by means of artificial ageing, in order to avoid damages due to unforeseen phenomena. The partners will have their main competence in ageing, monitoring of environmental pollution, and control of exhibitions and museums conditions.

The project is scheduled for completion in 2014.

The aspect I find most interesting is the ‘immovable art’. There was a controversy in Spain in 2011 over the prospect of opening some caves to tourists, from the Oct. 26, 2011 news item on ScienceDaily,

Plans to reopen Spain’s Altamira caves are stirring controversy over the possibility that tourists’ visits will further damage the 20,000-year old wall paintings that changed views about the intellectual ability of prehistoric people. That’s the topic of an article in the current edition of Chemical & Engineering News, ACS’ weekly newsmagazine. The caves are the site of Stone Age paintings so magnificent that experts have called them the “Sistine Chapel of Paleolithic Art.”

Carmen Drahl, C&EN associate editor, points out in the article that Spanish officials closed the tourist mecca to the public in 2002 after scientists realized that visitors were fostering growth of bacteria that damage the paintings. Now, however, they plan to reopen the caves. Declared a World Heritage Site by the United Nations’ Educational, Scientific and Cultural Organization (UNESCO), Altamira’s rock paintings of animals and human hands made scientists realize that Stone Age people had intellectual capabilities far greater than previously believed.

You can find an Oct. 6, 2011 piece about the Altamira rock paintings by Drahl titled, Keeping Visitors Out To Keep Cave Paintings Safe, on the Chemical and Engineering News (C&EN) blog. For anyone interested in more about rock art, there’s a UNESCO (United Nations Educational, Scientific, and Cultural Organization) World Rock Archives project or, as they call them, activity,

Due to their long sequence chronology, susceptibility to climate changes and vandalism, rock art sites are also among the most vulnerable on the World Heritage List.

Rock art, in the form of paintings and engravings, is a clear and lasting evidence of the transmission of human thoughts and beliefs through art and graphic representations. It functions as a repository of memory, enabling each culture to speak about themselves and their origins in all geographical settings.

I have two more items on cave art. The first is a piece I’ve been wanting to feature for almost two years. It’s an article on Slate by John Jeremiah Sullivan dated March 21, 2011 and titled, America’s Ancient Cave Art
Deep in the Cumberland Plateau, mysterious drawings, thousands of years old, offer a glimpse of lost Native American cultures and traditions. It’s an excerpt of an essay Sullivan wrote for the Paris Review. A fascinating exploration of a cave system that isn’t nearly as well known as France’s Lascaux Caves, here’s a snippet,

Over the past few decades, in Tennessee, archaeologists have unearthed an elaborate cave­-art tradition thousands of years old. The pictures are found in dark­ zone sites—places where the Native American people who made the artwork did so at personal risk, crawling meters or, in some cases, miles underground with cane torches—as opposed to sites in the “twilight zone,” speleologists’ jargon for the stretch, just beyond the entry chamber, which is exposed to diffuse sunlight. A pair of local hobby cavers, friends who worked for the U.S. Forest Service, found the first of these sites in 1979. They’d been exploring an old root cellar and wriggled up into a higher passage. The walls were covered in a thin layer of clay sediment left there during long­ ago floods and maintained by the cave’s unchanging temperature and humidity. The stuff was still soft. It looked at first as though someone had finger­-painted all over, maybe a child—the men debated even saying anything. But the older of them was a student of local history. He knew some of those images from looking at drawings of pots and shell ornaments that emerged from the fields around there: bird men, a dancing warrior figure, a snake with horns. Here were naturalistic animals, too: an owl and turtle. Some of the pictures seemed to have been first made and then ritually mutilated in some way, stabbed or beaten with a stick.

That was the discovery of Mud Glyph Cave, which was reported all over the world and spawned a book and a National Geographic article. No one knew quite what to make of it at the time. The cave’s “closest parallel,” reported the Christian Science Monitor, “may be caves in the south of France which contain Ice Age art.” A team of scholars converged on the site.

The sites range from Missouri to Virginia, and from Wisconsin to Florida, but the bulk lie in Middle Tennessee. Of those, the greater number are on the Cumberland Plateau, which runs at a southwest slant down the eastern part of the state, like a great wall dividing the Appalachians from the interior.

If you do decide to read the excerpt, you may want to reserve 30 to 45 minutes (at least).

For the last tidbit, here’s an introduction to TED (Technology, Entertainment and Design) Fellow, Genevieve von Petzinger’s work on cave art,

Genevieve von Petzinger’s [from the University of Victoria in British Columbia, Canada] database of prehistoric geometric shapes in cave art reveals some startling insights. More than mere doodles, the signs used across geological boundaries suggest there may have been a common iconography before people first moved out of Africa. When did people begin graphic communication, and what was its purpose? Genevieve studies these questions of our common heritage.

A very interesting interview follows that introduction.

As I more often cover movable art, I thought it was time to devote, again, at least part of a posting to immovable art.

SurFunCell project merges nanotechnology and renewable resources (cellulose) to create new materials

Given the current Canadian interest in forest-based cellulose research (ArboraNano; Canadian Forest NanoProducts Network and  CelluForce), this Jan. 11, 2013 news item on Nanowerk seems à propos (Note: A link has been removed),

EU-funded [European Union] scientists are bringing two of the most important fields of research together to develop novel multifunctional materials.

European scientists are merging renewable resources with nanotechnology with EU funding of the ‘Surface functionalisation of cellulose matrices using cellulose embedded nanoparticles’ (Surfuncell) project.

This Jan. 7, 2013 article (on the Cordis website) which originated the news item, provides more details about cellulose and the SurFunCell project,

Cellulose is a polysaccharide, a long-chain sugar that is the main constituent of plant cell walls. Investigators are creating new composite materials (consisting of more than one individual material) composed of nano-scaled polysaccharide layers with embedded nanoparticles. The new class of high-value bio-based materials with tailored functions will be applicable to separation technology, medical devices, sensors and electronic systems.

Surfuncell is focused on modifying the surface of cellulose-based materials with polysaccharide derivatives and nanoparticles. Aside from using renewable materials, the project employs surface modification rather than the conventional practice of using nanoparticles as fillers in a bulk matrix. Scientists are creating demonstrators in the fields of pulp and paper, cellulosic yarns, cellulose films and filter membranes.

Scientists have created numerous nanoparticles and cellulose derivatives that are the source of new materials being produced in pilot tests. Among these are antimicrobial fibres for textiles and separation membranes with reduced clogging behaviour.

The subsequent project phase will focus on implementing pilot plant production of cellophane foils with enhanced barrier properties and of ultraviolet (UV)-protected paper surfaces. Surfuncell is merging nanotechnology and the use of renewable resources to develop novel multifunctional products in a sustainable way.

There was some excitement last year when a CNC (the term cellulose nanocrystals seems to be gaining over nanocrystalline cellulose [NCC]) pilot plant was opened in Wisconsin (July 27, 2012 posting), the official opening of the CelluForce plant in Québec (Jan. 30, 2012 posting), and in 2011, there was the announcement of a pilot plant to be opened in Alberta (July 5, 2011 posting).

More about nanocellulose in Wisconsin (US)

Dr Joseph Jakes, materials engineer at the Forest Produsts Lab in Madison, Wisconsin, has been given a special US presidential award for his work on nanocelluose (from the July 30, 2012 news item  by Rich Christianson on the Woordworking Network,

Research to improve wood adhesives through the use of nanotechnology earned Dr. Joseph Jakes a Presidential Early Career Award for Scientists and Engineers (PECASE).

Jakes is author of Developing Tools to Assess Mechanical Properties of Wood Cell Walls. Jakes’ scientific paper notes,”Nanoindentation is a tool capable of probing mechanical properties at the sub-micrometer level, such as in wood cell walls, individual components in a wood-based composite, coatings, adhesive bond lines, etc.” Using this tool, Jakes writes, will help develop “advanced wood-based nanocomposites and to better understand wood-adhesive interactions.”

While there is mention of nanocellulose elsewhere in the news item, no details about its form(s), e.g. nanocrystalline cellulose (NCC),  are given.

New nanocrystalline cellulose plant in Wisconsin, US?

According to the July 25, 2012 article by Rick Barrett originally published by Milwaukee Journal Sentinel McClatchy-Tribune Information Services) on the equities.com website,

The U.S. Forest Products Laboratory, in Madison, says it’s opening a $1.7 million pilot plant that will support an emerging market for wood products derived from nanotechnology.

It also could boost Wisconsin’s paper industry by offering a new, high-value raw material made from wood pulp.

The pilot plant will supply nanocrystals to companies and universities that want to make materials from them or conduct their own experiments. For now, at least, it will employ just one person.

The first commercialized product to come from the program will likely be a paper coating. That could happen in a year, Rudie [Alan Rudie, a chemist and project leader of the nanotechnology program at the Forest Products Laboratory] said, and it will likely be several years before more advanced products come from the laboratory.

The program will make materials in kilogram quantities, something not readily available now. It will allow companies and universities to ramp up bigger projects because they will have the raw materials.

But while the Forest Products Laboratory wants to foster the technology, it doesn’t want to compete with businesses interested in producing the materials.

“We are part of the federal government, so we cannot compete against commercial companies. So if someone comes in and starts making these materials on a commercial level, we will have to get out of it,” Rudie said. That’s why, he added, the program has bought only equipment it can use for other purposes.

I suppose this nanomaterial from Wisconsin could be another crystalline substance  derived from wood but the description in the article makes it seem similar, if not identical, to the nanocrystalline cellulose (NCC) which is produced by the CelluForce plant in Windsor, Québec in quantities of 1000kg per day, according to publicity. (Information about the CelluForce plant opening, the efforts in Alberta, and other international inanocellulose *efforts *were mentioned in my Dec. 15, 2011 posting.)

I  note Rudie’s emphasis on not competing with commercial interests and wonder  about the situation with the Canadian plants which are funded both by federal and provincial government and commercial enterprises (Canada + Québec + Domtar = CelluForce and Canada +  Alberta+Alberta-Pacific Forest Industries, Inc. = plant production in Alberta).  In any event, I’m hoping the Canadian plants are going to be making their NCC accessible for Canadian innovators, inventors, and entrepreneurs, as well as, the research community. After all, how else does one expect innovation to occur?
