The second annual Physics and Astronomy Chili cook-Off will be held Tuesday, Jan 20th in room N304. We’ll be putting the video feed for the inauguration of President Barack Obama on the big screen, so come by to eat some spicy stew and watch history being made.
Prof. Samuel Amanuel and Anna Gaudette ’09 co-authored a paper with Prof. Sandy Sternstein of RPI in the December issue of the JOURNAL OF POLYMER SCIENCE PART B-POLYMER PHYSICS. The paper, titled “Enthalpic Relaxation of Silica-Polyvinyl Acetate Nanocomposites” was based on work done by Gaudette in Prof. Amanuel’s lab at Union. They studied the effect on of adding nanoparticles on the glass transition in a rubber compound.
The paper shows that nano particles substantially reduce physical aging in polymers, which has immediate application in industry such as determining shelf life, and predicting and enhancing long-term reliability of polymer products. The paper also provides crucial evidence to understand the underlying mechanism of reinforcement in polymer composites and polymer nanocomposites.
