Research investigates structural evolution and high-temperature sensing performance of polymer-derived SiAlBCN ceramics
Gang Shao's group from Zhengzhou University, China recently investigated the structural evolution of pentagonal polymer-derived SiAlBCN ceramics (PDCs) and outlined PDC-based sensor technology for high-temperature extreme environments. The high-perfo.....»»
New research employs shutter speed analogies to validate 55-year-old theory about chemical reaction rates
Chemical reactions are commonly depicted as transitions from reactants to products. However, such reactions involve many molecules, and the individual molecules themselves undergo frequently-occurring structural changes as they transform from the rea.....»»
