3 webinars worth a look: Vetting building materials, understanding DSC and measuring thermal conductivity

Ben Welter - Wednesday, September 02, 2015

Three on-demand webinars might be of interest to Phase Change Matters readers:

"Deep Material Vetting," offered through the U.S. Green Building Council, is aimed at designers struggling to find detailed toxicity data on building components. Instructors Chris Lee and Scott Kelly of Re:Vision Architecture share their "no-more-tears research strategies and time-saving workflows." Continuing education units are available: 1 GBCI CE hour, 1 AIA LU/HSW, 1 LFA hour. $45.

"Differential scanning calorimetry," offered by Mettler-Toledo International, explains the basic principles of DSC. For visual learners, it's a good companion to "Understanding the differential scanning calorimetry of PCMs." Free, but registration is required. 

"Enhancing Phase Change Materials," sponsored by C-Therm Technologies, takes a look thermal characterization tools. The presentation focuses on a South Korean study which found that adding exfoliated graphene nanoplatelets to phase change material can increase a PCM's thermal conductivity. Free, but registration is required.
