This is one of three pieces by Rita Letendre that underwent chemical mapping according to an August 5, 2020 CLS news release by Victoria Martinez (also received via email),

Research undertaken at the Canadian Light Source (CLS) at the University of Saskatchewan was key to understanding how to conserve experimental oil paintings by Rita Letendre, one of Canada’s most respected living abstract artists.

The work done at the CLS was part of a collaborative research project between the Art Gallery of Ontario (AGO) and the Canadian Conservation Institute (CCI) that came out of a recent retrospective Rita Letendre: Fire & Light at the AGO. During close examination, Meaghan Monaghan, paintings conservator from the Michael and Sonja Koerner Centre for Conservation, observed that several of Letendre’s oil paintings from the fifties and sixties had suffered significant degradation, most prominently, uneven gloss and patchiness, snowy crystalline structures coating the surface known as efflorescence, and cracking and lifting of the paint in several areas.

Kate Helwig, Senior Conservation Scientist at the Canadian Conservation Institute, says these problems are typical of mid-20th century oil paintings. “We focused on three of Rita Letendre’s paintings in the AGO collection, which made for a really nice case study of her work and also fits into the larger question of why oil paintings from that period tend to have degradation issues.”

Growing evidence indicates that paintings from this period have experienced these problems due to the combination of the experimental techniques many artists employed and the additives paint manufacturers had begun to use.

In order to determine more precisely how these factors affected Letendre’s paintings, the research team members applied a variety of analytical techniques, using microscopic samples taken from key points in the works.

“The work done at the CLS was particularly important because it allowed us to map the distribution of materials throughout a paint layer such as an impasto stroke,” Helwig said. The team used Mid-IR chemical mapping at the facility, which provides a map of different molecules in a small sample.

For example, chemical mapping at the CLS allowed the team to understand the distribution of the paint additive aluminum stearate throughout the paint layers of the painting Méduse. This painting showed areas of soft, incompletely dried paint, likely due to the high concentration and incomplete mixing of this additive. 

The painting Victoire had a crumbling base paint layer in some areas and cracking and efflorescence at the surface in others.  Infrared mapping at the CLS allowed the team to determine that excess free fatty acids in the paint were linked to both problems; where the fatty acids were found at the base they formed zing “soaps” which led to crumbling and cracking, and where they had moved to the surface they had crystallized, causing the snowflake-like efflorescence.

AGO curators and conservators interviewed Letendre to determine what was important to her in preserving and conserving her works, and she highlighted how important an even gloss across the surface was to her artworks, and the philosophical importance of the colour black in her paintings. These priorities guided conservation efforts, while the insights gained through scientific research will help maintain the works in the long term.

In order to restore the black paint to its intended even finish for display, conservator Meaghan Monaghan removed the white crystallization from the surface of Victoire, but it is possible that it could begin to recur. Understanding the processes that lead to this degradation will be an important tool to keep Letendre’s works in good condition.

“The world of modern paint research is complicated; each painting is unique, which is why it’s important to combine theoretical work on model paint systems with this kind of case study on actual works of art” said Helwig. The team hopes to collaborate on studying a larger cross section of Letendre’s paintings in oil and acrylic in the future to add to the body of knowledge.

There are many presentations focused on COVID-19 and.or health.

There doesn’t seem to be much focus on cyber security and, given that we just lost two ice caps (see Brandon Spektor’s August 1, 2020 article [Two Canadian ice caps have completely vanished from the Arctic, NASA imagery shows] on the Live Science website), it’s surprising that there are no presentations concerning the Arctic.

International Symposium on Electronic Arts (ISEA) 2020

According to my latest information, the early bird rate for ISEA 2020 (Oct. 13 -18) ends on August 13, 2020. (My June 22, 2020 posting describes their plans for the online event.)

You can find registration information here.

Margaux Davoine has written up a teaser for the 2020 edition of ISEA in the form of an August 6, 2020 interview with Yan Breuleux. I’ve excerpted one bit,

Finally, thinking about this year’s theme [Why Sentience?], there might be something a bit ironic about exploring the notion of sentience (historically reserved for biological life, and quite a small subsection of it) through digital media and electronic arts. There’s been much work done in the past 25 years to loosen the boundaries between such distinctions: how do you imagine ISEA2020 helping in that?

The similarities shared between humans, animals, and machines are fundamental in cybernetic sciences. According to the founder of cybernetics Norbert Wiener, the main tenets of the information paradigm – the notion of feedback – can be applied to humans, animals as well as the material world. Famously, the AA predictor (as analysed by Peter Galison in 1994) can be read as a first attempt at human-machine fusion (otherwise known as a cyborg).

The infamous Turing test also tends to blur the lines between humans and machines, between language and informational systems. Second-order cybernetics are often associated with biologists Francisco Varela and Humberto Maturana. The very notion of autopoiesis (a system capable of maintaining a certain level of stability in an unstable environment) relates back to the concept of homeostasis formulated by Willam Ross [William Ross Ashby] in 1952. Moreover, the concept of “ecosystems” emanates directly from the field of second-order cybernetics, providing researchers with a clearer picture of the interdependencies between living and non-living organisms. In light of these theories, the absence of boundaries between animals, humans, and machines constitutes the foundation of the technosciences paradigm. New media, technological arts, virtual arts, etc., partake in the dialogue between humans and machines, and thus contribute to the prolongation of this paradigm. Frank Popper nearly called his book “Techno Art” instead of “Virtual Art”, in reference to technosciences (his editor suggested the name change). For artists in the technological arts community, Jakob von Uexkull’s notion of “human-animal milieu” is an essential reference. Also present in Simondon’s reflections on human environments (both natural and artificial), the notion of “milieu” is quite important in the discourses about art and the environment. Concordia University’s artistic community chose the concept of “milieu” as the rallying point of its research laboratories.

ISEA2020’s theme resonates particularly well with the recent eruption of processing and artificial intelligence technologies. For me, Sentience is a purely human and animal idea: machines can only simulate our ways of thinking and feeling. Partly in an effort to explore the illusion of sentience in computers, Louis-Philippe Rondeau, Benoît Melançon and I have established the Mimesis laboratory at NAD University. Processing and AI technologies are especially useful in the creation of “digital doubles”, “Vactors”, real-time avatar generation, Deep Fakes and new forms of personalised interactions.

I adhere to the epistemological position that the living world is immeasurable. Through their ability to simulate, machines can merely reduce complex logics to a point of understandability. The utopian notion of empathetic computers is an idea mostly explored by popular science-fiction movies. Nonetheless, research into computer sentience allows us to devise possible applications, explore notions of embodiment and agency, and thereby develop new forms of interaction. Beyond my own point of view, the idea that machines can somehow feel emotions gives artists and researchers the opportunity to experiment with certain findings from the fields of the cognitive sciences, computer sciences and interactive design. For example, in 2002 I was particularly marked by an immersive installation at Universal Exhibition in Neuchatel, Switzerland titled Ada: Intelligence Space. The installation comprised an artificial environment controlled by a computer, which interacted with the audience on the basis of artificial emotion. The system encouraged visitors to participate by intelligently analysing their movements and sounds. Another example, Louis-Philippe Demers’ Blind Robot (2012),  demonstrates how artists can be both critical of, and amazed by, these new forms of knowledge. Additionally, the 2016 BIAN (Biennale internationale d’art numérique), organized by ELEKTRA (Alain Thibault) explored the various ways these concepts were appropriated in installation and interactive art. The way I see it, current works of digital art operate as boundary objects. The varied usages and interpretations of a particular work of art allow it to be analyzed from nearly every angle or field of study. Thus, philosophers can ask themselves: how does a computer come to understand what being human really is?

I have yet to attend conferences or exchange with researchers on that subject. Although the sheer number of presentation propositions sent to ISEA2020, I have no doubt that the symposium will be the ideal context to reflect on the concept of Sentience and many issues raised therein.

For the last bit of news.

HotPopRobot, one of six global winners of 2020 NASA SpaceApps COVID-19 challenge

I last wrote about HotPopRobot’s (Artash and Arushi with a little support from their parents) response to the 2020 NASA (US National Aeronautics and Space Administration) SpaceApps challenge in my July 1, 2020 post, Toronto COVID-19 Lockdown Musical: a data sonification project from HotPopRobot. (You’ll find a video of the project embedded in the post.)

Here’s more news from HotPopRobot’s August 4, 2020 posting (Note: Links have been removed),

Artash (14 years) and Arushi (10 years). Toronto.

We are excited to become the global winners of the 2020 NASA SpaceApps COVID-19 Challenge from among 2,000 teams from 150 countries. The six Global Winners will be invited to visit a NASA Rocket Launch site to view a spacecraft launch along with the SpaceApps Organizing team once travel is deemed safe. They will also receive an invitation to present their projects to NASA, ESA [European Space Agency], JAXA [Japan Aerospace Exploration Agency], CNES [Centre National D’Etudes Spatiales; France], and CSA [Canadian Space Agency] personnel. https://covid19.spaceappschallenge.org/awards

15,000 participants joined together to submit over 1400 projects for the COVID-19 Global Challenge that was held on 30-31 May 2020. 40 teams made to the Global Finalists. Amongst them, 6 teams became the global winners!

The 2020 SpaceApps was an international collaboration between NASA, Canadian Space Agency, ESA, JAXA, CSA,[sic] and CNES focused on solving global challenges. During a period of 48 hours, participants from around the world were required to create virtual teams and solve any of the 12 challenges related to the COVID-19 pandemic posted on the SpaceApps website. More details about the 2020 SpaceApps COVID-19 Challenge:  https://sa-2019.s3.amazonaws.com/media/documents/Space_Apps_FAQ_COVID_.pdf

We have been participating in NASA Space Challenge for the last seven years since 2014. We were only 8 years and 5 years respectively when we participated in our very first SpaceApps 2014.

We have grown up learning more about space, tacking global challenges, making hardware and software projects, participating in meetings, networking with mentors and teams across the globe, and giving presentations through the annual NASA Space Apps Challenges. This is one challenge we look forward to every year.

It has been a fun and exciting journey meeting so many people and astronauts and visiting several fascinating places on the way! We hope more kids, youths, and families are inspired by our space journey. Space is for all and is yours to discover!

If you have the time, I recommend reading HotPopRobot’s August 4, 2020 posting in its entirety.

NANOART Research Tool offers affordable paint analysis

There’s some encouraging news for art conservators and authenticators, an affordable nanotech-based kit for greater accuracy analyzing ancient (or old)  paint is one step closer according to a Jan. 11, 2016 notice on CORDIS,

Developed through the EU-funded NANOART project, the new testing kit has already been applied to identify binders such as collagen and ovalbumin in ancient paint, not only in model samples painted in the lab but also in real samples collected from works of art.

‘Once fully completed, our new tool will be made available to conservation scientists from around the world at an affordable cost (an assay can cost around EUR 0.5 per target), which will facilitate greater knowledge about historical works of art and help international museums, restoration art studios and laboratories to plan the best conservation and preventive strategies,’ explains NANOART project coordinator Dr Jesus de la Fuente from the CSIC/University of Zaragoza, Spain.

In addition, the sensitiveness of the project’s new nanotechnology-based methods means that smaller samples are required to be taken from the artwork for analysis. This in itself will help to better preserve our cultural heritage.

In order to characterise ancient paints, experts have often relied on conventional molecular biology methodologies that were developed decades ago. The concept behind the NANOART project was that these techniques could be substituted by more sensitive, inexpensive and faster techniques that take advantage of emerging nanotechnologies.

Furthermore, conventional methods – apart from being expensive – are also only available at a few laboratories, and require specialised personnel and equipment. A key objective of the NANOART project has been to address the cost issue by applying techniques developed for clinical diagnosis. In this way, the project is also highly original as it aims to take latest developments in clinical medicine and apply them to the conservation and preservation of cultural heritage.

‘The innovative nature of the project is also denoted by the fact that there is currently no method or kit available that can be easily used at point-of-care to analyse paints without requiring expensive equipment and extensive training,’ says Ana Claro, research fellow from the INA/University of Zaragoza. ‘With the NANOART kit, the final user will be able to conduct an affordable analysis (in some cases at the cost of only a few euros) by simply following the instructions. Within a four-hour period, the results will be available.’

The potential opportunities opened up by the new analytical nanotechnology are huge. For example, developed in parallel with the NANOART kit, a spin-off company called NanoImmunotech has been launched in order to develop devices to detect bacterial infection in meat using the same technology as used in NANOART.

‘This opens our technology to other applications far from cultural heritage applications,’ says de la Fuente. ‘However, we would like to continue further developing novel uses of NANOART technology for other applications in cultural heritage, and our next step will be to look for funding to develop an even more user friendly device.’

This announcement comes just as the NANOART project is scheduled to be completed (Jan. 31, 2016) according to its webpage on CORDIS.

For those with Spanish language skills, there’s this Jan. 11, 2016 news item on the Catalunya Vanguardista website (I believe the English language version above is a machine translation with this being the original text),

Nanotecnología para analizar pinturas históricas de forma barata y precisa

Empleando nanotecnologías, se ha creado un equipo de diagnóstico clínico destinado a analizar capas de pintura antiguas que podría ahorrar costes a los profesionales de la conservación y permitirles alcanzar mayor precisión.

Cordis / El nuevo equipo de ensayo, desarrollado mediante el proyecto financiado con fondos europeos NANOART, ya se ha empleado en la identificación de aglutinantes como el colágeno y la ovoalbúmina en pinturas históricas. Además, los resultados se han obtenido tanto con muestras pintadas en el laboratorio como con otras extraídas de obras de arte.

«Una vez completemos su desarrollo, nuestra herramienta quedará a disposición de científicos de todo el mundo dedicados a la conservación por un módico precio (cada ensayo costará cerca de medio euro por objetivo). De este modo se obtendrá un conocimiento más profundo sobre las obras de arte históricas y tanto museos como talleres de restauración y laboratorios podrán plantear las estrategias de conservación y prevención idóneas», explicó el coordinador del proyecto, el Dr. Jesús de la Fuente del Instituto de Ciencia de los Materiales —centro mixto dependiente del CSIC y la Universidad de Zaragoza (España)—.Además, la sensibilidad ofrecida por los métodos nanotecnológicos propuestos por el proyecto permite extraer muestras de menor tamaño de las obras de arte, lo cual contribuirá a conservar mejor el patrimonio cultural.Para caracterizar pinturas antiguas, hasta ahora los expertos solían emplear metodologías convencionales de la biología molecular desarrolladas hace decenios. La propuesta del proyecto NANOART pasa por sustituir estas técnicas por otras más sensibles, baratas y rápidas que se valen de las nanotecnologías emergentes.

Es más, los métodos convencionales, además de resultar caros, sólo están a disposición de unos pocos laboratorios que cuentan con equipos y personal especializados. NANOART se propuso sobre todo abaratar los costes mediante el empleo de técnicas de diagnóstico del ámbito clínico. La originalidad de este planteamiento es notoria, pues aprovecha los últimos progresos logrados en medicina clínica para aplicarlos a la conservación y la protección del patrimonio cultural.

«La naturaleza innovadora del proyecto también obedece a la carencia hoy en día de un método o equipo que pueda emplearse con facilidad in situ para analizar pinturas sin necesidad de equipos caros ni formación exhaustiva», afirmó Ana Claro, investigadora del INA de la Universidad de Zaragoza. «Gracias al equipo de NANOART, el usuario final podrá ejecutar ensayos asequibles, en algunos casos por valor de tan sólo unos pocos euros, siguiendo las instrucciones proporcionadas. Los resultados estarán disponibles en cuatro horas».

Las oportunidades que ofrece la nueva nanotecnología analítica son enormes. Por ejemplo, la empresa derivada NanoImmunotech se ha puesto en marcha en paralelo al desarrollo del equipo de NANOART para que cree servicios con los que detectar infecciones bacterianas en la carne mediante los mismos métodos empleados por el proyecto en el ámbito del arte.

«De esta forma se amplían las aplicaciones de la tecnología a otros campos muy alejados del patrimonio cultural», afirmó de la Fuente. «No obstante, seguiremos indagando en nuevos usos de la tecnología de NANOART relacionados con el patrimonio cultural y procederemos ya a buscar fuentes de financiación que nos permitan crear un dispositivo aún más fácil de usar».

I expect the folks at the Canadian Conservation Institute (CCI) and other such insitutions are keeping a close eye on developments of this nature. The institute was mentioned here in the context of a series I wrote on attempts to authenticate a painting, Autumn Harbour, as a Lawren Harris (one of Canada’s Group of Seven painters). My July 14, 2014 post was devoted to a response from Marie-Claude Corbeil to a query about scientific investigation of visual art,

… [the response],

The Canadian Conservation Institute (CCI) has been conducting research into the materials and techniques of Canadian artists (mainly 20th-century artists) since the early 1990s. Databases were created for each artists. At the moment CCI has no such database on Harris.

The CCI is the only institution in Canada carrying out this kind of research. I would add that European conservation institutes or laboratories have a long tradition of conducting this type of research focusing mainly on European art, basically because many were created long before North-American conservation institutes or laboratories were established.

I was quite fascinated by the whole thing and wrote a four-part series about Autumn Harbour, Lawren Harris, and much more, as well as, the July 14, 2014 post, which has links to the Autumn Harbour series along with the response from the CCI and links to articles recommended by Corbeil.
