Fracture mechanical behavior of polymers: 1. Amorphous glassy state [PDF]
Theoretical analyses and experiments have been carried out to investigate fracture behavior of glassy polymers. Our birefringence measurements quantify the local stress buildup at cut tip during different stages of drawing. Based on polymethyl methacrylate (PMMA), bisphenol A polycarbonate (PC) and polyethylene terephthalate (PET), we find several key ...

Influence of BPA exposure, measured in saliva, on childhood weight
IntroductionEndocrine disruptors such as bisphenol A (BPA), BPA glycidyl methacrylate, and other BPA acrylate–based derivatives have been related to type 2 diabetes, the metabolic syndrome, and obesity, among other metabolic disorders.

Immediate Hypersensitivity Reaction to Composite Restorations
Restorative materials used in dentistry are constantly exposed to salivary components like enzymes that have a high impact on the degradation of these materials and subsequent leaching of some of their constituents which may be harmful to the oral ...

Annealing Free, Clean Graphene Transfer using Alternative Polymer Scaffolds [PDF]
We examine the transfer of graphene grown by chemical vapor deposition (CVD) with polymer scaffolds of poly(methyl methacrylate) (PMMA), poly(lactic acid) (PLA), poly(phthalaldehyde) (PPA), and poly(bisphenol A carbonate) (PC). We find that optimally reactive PC scaffolds provide the cleanest graphene transfers without any annealing, after extensive ...
