The loss of catalytic activity (irreversible denaturation) of α -chymotrypsin (EC 3.4.21.1) as a function of pH between 6 and 13 is described. Around neutrality the irreversible denaturation is second ...

This article discusses the use of the high-temperature reaction cell for studying the processes occurring on a novel catalyst surface. Silica supported Co(OH) 2 was studied before and after ...

Following the discovery of graphene, its two-dimensional (2D) structure and its electronic and mechanical properties have gained much attention from the research community. Graphene is extensively ...

Two dry solids --- barium hydroxide and ammonium nitrate --- are mixed to produce an endothermic reaction. The temperature of the mixture drops approximately 45oC and is cold enough to freeze the ...
