The biodegradation of plasticizers has been previously shown to result in the accumulation of metabolites that are more toxic than the initial compound. The present work shows that the pattern of degradation of di-2-ethylhexyl adipate by Bacillus subtilis can be

2-Ethyl-1-hexanol (2E1H) is a possible causative chemical for sick building symptoms; however, thus far, we do not have a clear understanding of the indoor air pollution levels caused by it. In this study, first, airborne 2E1H concentrations were measured during

The dielectric spectra of most simple liquids are characterized by two relaxation processes: (i) the alpha-process, an intense, broad non-Debye relaxation with a non-Arrhenius temperature dependence and (ii) a beta process, evident mainly below the glass transition and having nearly
The feasibility of using native lipase A from Candida antarctica (CAL-A) to esterify fatty acids with water-insoluble alcohols in the presence of excess water was investigated in stirred-tank reactors. For high reaction rates, a ratio of water:substrates of 0.6-1.4:1 (v/v)

Many hydrogen-bonded liquids, especially glass-forming cases, display a dielectric relaxation behavior that differs qualitatively from that of other simple liquids. The majority of models aimed at explaining this unusual dielectric behavior associate the prominent Debye process with structural relaxation, viscous
Mesoporous materials, such as aerogels, offer advantages for practical hydrogen storage. They have large surface areas, open porosity, small pore sizes, and the ability to coat the surface with one or more compounds.
