NMR spectroscopy ((1)H, (13)C, (15)N) shows that carbon disulfide reacts spontaneously with 1-butyl-1-methylpyrrolidinium acetate ([BmPyrro][Ac]) in the liquid phase. It is found that the acetate anions play an important role in conditioning chemical reactions with CS2 leading, via coupled complex reactions, to the degradation of this molecule to form thioacetate anion (CH3COS(-)), CO2, OCS, an...

In the title molecular salt, C(5)H(6)ClN(2) (+)·C(7)H(6)NO(2) (-), the cations and anions are connected by cation-to-anion and anion-to-anion N-H⋯O hydrogen bonds into a three-dimensional network. The dihedral angle between the ring and the CO(2) group in the anion is 7.14 (7)°.

The project was planed to study the effect of varying dietary cation-anoin balance on the growth performance of broilers. One hundred and twenty day-old (Hubbard) broiler chicks were purchased from a local hatchery and reared in a group for one week of age. At the start of second week, birds were randomly distributed in 12 pens (10 chicks per pen). Four isonitrogenous and isocaloric starter and...

Using molecular dynamics (MD) simulations in conjunction with the SPC/E water model, we optimize ionic force-field parameters for seven different halide and alkali ions, considering a total of eight ion-pairs. Our strategy is based on simultaneous optimizing single-ion and ion-pair properties, i.e., we first fix ion-water parameters based on single-ion solvation free energies, and in a second s...

Despite the innumerous papers regarding the study of the ionic liquids as a potential candidate for CO2 capture, many details concerning the structure and dynamics of CO2 in the system are still to be revealed, i.e., the correlation between the local environment structure and the dynamic properties of the substance. This present work relied on the performance of molecular dynamics both for the ...

In article number 2006768, Hyukjin J. Kwon, Geunbae Lim, and Minsoo Lee introduce a multiscale-porous anion exchange membrane (MP-AEM), as an easily accessible anion-permselective material for the electrokinetic concentration of cationic species. The MP-AEM's highly streamlined fabrication process enables convenient cation-selective concentrator assembly, its demonstrated scalability shows grea...

In this work, Aliquat 336 ([Aliquat+]) based ionic liquids containing the fluorinated anion bis(trifluoromethylsulfonyl)imide [NTf2−] was successfully prepared by anionic exchange replacement of chloride anion. The reaction lithium with N-Methyl-N,N,N-trioctylammonium ([N1,8,8,8][Cl] in water lead to corresponding IL, namely ([Aliquat+][NTf2−]). obtained liquid characterized using infrared and ...

In the cation of the title solvated mol-ecular salt, C12H14ClN4 (+)·C14H8F3O2S(-)·C2H6OS [systematic name of the cation: 2,4-di-amino-5-(4-chloro-phen-yl)-6-ethyl-pyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chloro-phenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modell...
