Artificially structured boundary plasma trap

This article presents a computer simulation of single-species non-neutral plasma confinement using an artificially structured boundary. The results support the prospect of developing plasma space-charge based confinement, with an unmagnetized plasma of one species of charged particles confined by an electric field produced by an edge-confined plasma of a second species of charged particles.

Multiple levers for overcoming the recalcitrance of lignocellulosic biomass (open access)

Multiple levers for overcoming the recalcitrance of lignocellulosic biomass

The article evaluates the impacts of physical, chemical and genetic interventions to improve biomass processing singly and in combination. Based on their results and literature studies, some form of non-biological augmentation will likely be necessary for the foreseeable future to achieve high total carbohydrate solubilization (TCS) for most cellulosic feedstocks. The results show that this need not necessarily involve thermochemical processing, and need not necessarily occur prior to biological conversion.

Further Analysis on Solubility Measurement and Thermodynamic  Modeling of Benzoic Acid in Monosolvents and Binary Mixtures (open access)

Further Analysis on Solubility Measurement and Thermodynamic Modeling of Benzoic Acid in Monosolvents and Binary Mixtures

Article discussing further analyses of the recent report (by Sandeepa et al.) on the solubility of benzoic acid in six monosolvents (i.e. tributyl phosphate, diacetone alcohol, methyl-n-propyl ketone, methyl acetate, amyl acetate, and isooctane) and five binary systems (i.e. ethanol + hexane, isopropyl alcohol + hexane and chloroform + hexane, acetone + hexane, and acetone + water) along with some numerical analyses. The reported calculations have been reanalyzed based on combined nearly ideal binary solvent/Redlich-Kister, the modified Wilson model, general single model, Jouyban–Acree model and Jouyban–Acree–van’t Hoff model. The investigated models provide good estimation of the solubility behavior of benzoic acid in the binary solvent mixtures at various temperatures.
