The main objective of the present work was to synthesize and characterize three novel lipase-friendly deep eutectic solvents (DESs) using cholinium dihydrogen phosphate (N1112OHDHP) as hydrogen bond acceptor ethylene glycol (EG) and/or glycerol (GL) donors in following proportions: N1112OHDHP:EG (molar ratio 1:2), N1112OHDHP:GL 1:2) N1112OHDHP:EG:GL 1:1:1). FTIR, 1H NMR, TGA DSC were employed s...

Abstract Silicon (Si)‐based anodes have long been viewed as the next promising solution to improve performance of modern lithium‐ion batteries. However, poor cycling stability Si‐based impedes their application and calls for solutions further improvements. In present work, incorporation phosphate groups on surface an amorphous Si‐carbon composite (a‐Si/C) has achieved by a hydrothermal reaction...

Establishment of hydrophilic organic/salt-containing aqueous two-phase system and purification of salvianolic acid B from crude extract of S. miltiorrhiza by counter-current chromatography with said system were studied. Ethanol and n-propanol were selected to constitute biphasic systems with ammonia sulphate, sodium chloride and phosphate separately, and related system characteristics including...

The purpose of the present study was to elucidate differences in actual work environments, mobility and satisfaction between firefighters wearing aluminized and non-aluminized personal protective equipment (PPE), and to suggest a proper standard test method for Japanese firefighters' PPE. A survey from two cities in Japan (City A: aluminized PPE; City B: non aluminized PPE) was undertaken. A to...
