A molecular dynamics model for clays and the oxide minerals is desirable studying kinetics thermodynamics of adsorption processes. To this end, a valence force field aluminous, dioctahedral clay was developed. Novel aspects development include bending potential octahedral O−Al−O angles, which uses quartic polynomial to create double-well with minima at both 90° 180°. Also, atomic point charges were derived from comparisons ab initio electrostatic potentials X-ray diffraction-based...

Organic and microbial contaminants of emerging concern (CECs), even though not yet regulated, are great in reclaimed water reuse projects. Due to the large number CECs their different characteristics, it is useful include only a limited them monitoring programs. The selection most representative still current open question. This study presents new methodology for this scope, particular evaluation performance polishing treatment assessment risk environment irrigated crops. As organic CECs,...

The current study aimed to investigate major knowledge gaps regarding the application of anodic oxidation (AO) process with boron-doped diamond (BDD) anodes for remediation water matrices contaminated per- and polyfluoroalkyl substances (PFAS). This included: (i) degradation ultrashort-chain (C1-C3) long-chain (C9-C13) PFAS in addition short- medium-chain (C4-C8) PFAS, (ii) multi-solute systems different content (0.2 µg L-1 versus 2.0 L-1) diversity (24 C1-C13 8 C1-C8) single-solute systems,...

The molecular structures of four conformations N-acetyl–N′-methyl glycyl amide were refined by geometrically unconstrained ab initio gradient relaxation on the 4–21G level. most stable form I contains a seven-membered ring closed hydrogen bonding. A second local minimum II is less than 1 kcal/mol above and represents fully extended with five-membered bonded ring. two other minima refined, III IV, are open forms which 4–5 I. geometries make it possible to estimate significance geometries, in...

With respect to the investigation of low pressure filament-assisted chemical vapor deposition processes for diamond formation, absolute concentrations atomic hydrogen were determined by two-photon laserinduced fluorescence in vicinity a heated filament an environment containing H(2) or mixtures H(2)and CH(4). Radial H concentration profiles obtained different pressures and temperatures, diameters, materials. The influence addition various amounts methane on atom was examined.
