The average and local glass transition temperatures (Tgs) and physical aging behavior of various confined polymers were studied in order to gain an understanding of these surface/interface effects and their propagation into the polymer. Using a novel multilayer/fluorescence method, the Tgs of layers at the free surface, substrate-polymer interface, and...
PRC is a PGC-1 coactivator family member responsive to serum growth factors and up regulated in proliferating cells. Unlike PGC-1α and PGC-1β, PRC has not been studied extensively and and its function or regulation remains largely unknown. Both PGC-1α and PGC-1β have been shown to be important regulators of mitochondrial...
