Abstract The physical and chemical structure of activated carbon (AC) varies with the carbonization temperature, activation process and time. The texture and toughness of the starting raw material also determine the morphology of AC produced. The Bru

Enzymes reign over inorganic and organometallic catalysts in aspects of conversion and product selectivity. Natural products are always produced in small quantities and to mimic such biological setups for large-scale production requires harsh solvent

Abstract: The activity and selectivity of W110G Thermoanaerobacter ethanolicus secondary alcohol dehydrogenase were altered by cosubstrate and cosolvent at varying temperatures. A sharp drop in the enantiomeric excess (ee) was observed at 60 oC in th

Maternal breast milk, which is a complete food for the infant's growth, development, and health, contains fats and lipids making it susceptible to accumulation of lipophilic compounds like polycyclic aromatic hydrocarbons (PAHs). This study aimed at

We developed a single-enzyme-mediated two-step approach for deracemization of secondary alcohols. A single mutant of Thermoanaerobacter ethanolicus secondary alcohol dehydrogenase enables the nonstereoselective oxidation of racemic alcohols to ketone
