Ultra-thin gold nanowires (GNWs), with uniform surface crystallinity, appear much more active than gold nanoclusters in benzylic compound oxidation. Ethylbenzene oxidation was used as a model reaction and a radical chain reaction mechanism was revealed by the DFT method.
The determination region of solubility of methanol with gasoline of high aromatic content was investigated experimentally at temperature of 288.2 K. A type 1 liquid-liquid phase diagram was obtained for this ternary system. These results were correlated simultaneously by the UNIQUAC model. The values of the interaction parameters between each pair of components in the system were obtained f...

Blood BTEX levels were e...
The work gives estimation of volatile aromatic hydrocarbons content in the water small rivers Khabarovsk December 2021. maximum concentrations benzene, ethylbenzene, xylenes and pseudocumol were noted Kurcha-Murcha river draining refinery area.
BACKGROUND Artificial Neural Networks (ANNs) are introduced as robust and versatile tools in quantitative structure-activity relationship (QSAR) modeling. Their application to the modeling of enzyme reactivity is discussed, along with methodological issues. Methods of input variable selection, optimization of network internal structure, data set division and model validation are discussed. The ...
Organic glass films formed by physical vapor deposition exhibit enhanced stability relative to those formed by conventional liquid cooling and aging techniques. Recently, experimental and computational evidence has emerged indicating that the average molecular orientation can be tuned by controlling the substrate temperature at which these "stable glasses" are grown. In this work, we present a ...
A statistical-mechanical treatment of the solubilization in micelle is presented in combination with molecular simulation. The micellar solution is viewed as an inhomogeneous and partially finite, mixed solvent system, and the method of energy representation is employed to evaluate the free-energy change for insertion of a solute into the micelle inside with a realistic set of potential functio...
A short primer on benzene, toluene, ethylbenzene and xylenes (BTEX) in the environment and in hydraulic fracturing fluids Dr Frederic Leusch and Dr Michael Bartkow, Griffith University – Smart Water Research Centre 17 Nov 2010 1. Some notes about concentrations Concentrations in water in this document are generally given as part‐per‐billion (ppb), equivalent to one microgram per litre (μg/L). ...
