Spatially resolved structure and dynamics of the hydration shell of Pyridine (cas 110-86-1) in sub- and supercritical water08/27/2019

Molecular dynamics simulations of a pyridine solute in sub- and supercritical water are performed to investigate the organization and dynamics of water molecules at different parts of the solute solvation shell. The radial/angular and spatial orientational functions provide information on the sp...detailed

Periodic mesoporous organosilicas possessing molecularly mixed Pyridine (cas 110-86-1) and benzene moieties in the frameworks08/26/2019

Periodic mesoporous organosilicas (PMOs) were synthesized from precursor mixtures of bridged organosilanes containing various ratios of divinylbenzene (vPh) and divinylpyridine (vPy) under basic conditions. The bifunctional vPh-vPy-PMOs exhibited ordered mesoporous structures and molecular scale...detailed

Bioavailable electron donors leached from leaves accelerate biodegradation of Pyridine (cas 110-86-1) and quinoline08/25/2019

Fallen leaves of Platanus orientalis and Ginkgo biloba linn were separately immersed in water to obtain leachates that were used as exogenous electron donors for accelerating pyridine and quinoline biodegradations. Leachate addition accelerated the pyridine removal rate by up to 4.4% and 3.6% an...detailed
