Of course, HSC cannot solve all chemical problems, because it does not take into account the kinetics (rates) of chemical reactions and the non-ideality of solutions. However, in many cases it is a very inexpensive and useful tool which helps to find the optimal reaction conditions and yields...

A hazard of using kinetic information to identify a reaction mechanism, however, is that more than one mechanism might result in the same rate law, especially when approximate solutions are derived. For this reason, proposed reaction mechanism must be supported by additional evidence. Kinetics is...

Weakly hydrated anions bind to polymers but not monomers in aqueous solutions Weakly hydrated anions solubilize macromolecules but cause small molecules that are made from identical chemical constituents to precipitate out of aqueous solutions. Now, this phenomenon has been understood by demonstrating that...
-Electrocatalytic CO2Reduction.Improving the selectivity of the electrocatalytic CO2reduction reaction (CO2RR) over hydrogen evolution in aqueous solutions is greatly needed, but the process is difficult to achieve because the two reactions occur at close th...
Oftentimes, in searching for the shortest, most efficient synthetic route, process chemists must devise creative synthetic solutions that eliminate costly functional group manipulations and oxidation/reduction steps. This article will focus exclusively on the chemical and manufacturing processes associated with...
