American Institute Of Conservation Conference
05/29/2018 11:31 to 06/02/2018 11:32 (America/Montreal)
Host: Rez Mani did an M.Eng in Engineering Physics focused on optical properties of semiconductors from McMaster University in Hamilton, Ontario. This was followed by a Ph.D. in Earth and Space Science focused on satellite optical instrumentation from York University in Toronto, Ontario. After working in the industry for 10 years, where he participated in a multitude of optical/laser/spectroscopic projects, he returned to York University as a contract faculty and a research associate in 2011. He has also worked for Allied Scientific Pro as a consultant since 2011 and as an application scientist since 2017.
Webinar Description: The webinar begins by explaining the fundamental differences between the near IR and mid-IR spectroscopy methods. The fundamental absorption bands exist in the mid-IR region, however overtones which are weaker can be found in the near IR region. Mid-IR instruments such as FTIR are expensive and bulky. Several industries are now turning to near IR spectroscopy for quality control since it is a fast and inexpensive method which uses light-weight portable spectrometers. NIR can be used to find the ingredients of food such as sugar, protein, moisture and fat, find ingredients of drugs, sort plastics for recycling, detect influenza virus in nasal fluid, detect Zika virus in mosquitoes, find polyester content of fabrics, and many other applications. Instead of using an array detector which is more expensive, a new method called Digital Light Processing (DLP) uses micro-mirrors to shine different parts of the spectrum one after another onto a single element detector and builds the spectrum. The technology and its applications are very promising. Use of chemometrics methods such as Partial Least Square (PLS) to make quantitative predictions is also discussed. .

About: Papers were solicited that demonstrate the impact of material studies – or studies of materials – on the conservation profession, including the emergence of innovative treatments, new ways of “looking” and “seeing,” shifts in decision-making and desired outcomes, and changes in collection care strategies. Also welcome were explorations of the impact of trending “materiality” studies on related disciplines including archaeology, museum and curatorial fields, and art history among others. Topics include, but are not limited to: cutting-edge imaging and analysis techniques of materials, new materials having conservation applications, revelations about the meaning and significance of materials within an artist’s work, and improved methods of authentication. Four concurrent general session sub-themes have been identified with more to be identified based on the submissions
When: May 29th - June 2nd, 2018
