We have investigated the reaction of peroxynitrite with carbon dioxide in aqueoussolution by means of combined quantum-classical (QM-MM) molecular dynamics simulations.In our QM-MM scheme, the reactant was modeled using ...

Forests play an important role in water and carbon cycles in semiarid regions such as the Mediterranean ecosystems. Previous research in the Chilean Mediterranean forests revealed a break point in 1980 in regional tree-r...

Polyphenol Oxidases (PPOs) catalyze the conversion of phenolic substrates to quinones, leading to the formation of dark-colored precipitates in fruits and vegetables. This process, known as enzymatic browning, is the cau...
