We report a new lattice structure of the ionic clathrate hydrate of tetra-n-butylammonium bromide induced by guest CO2 molecules, which is found to provide high CO2 storage capacity. The structure was characterized by a set of methods, including single crystal X-ray diffraction, NMR, and MD simulations.

By the reaction of TBA(4)H(4)[γ-SiW(10)O(36)] (TBA = tetra-n-butylammonium) with AgOAc (OAc = acetate) using dimethylphenylsilane as a reductant in acetone, a unique polyoxometalate containing a discrete octahedrally shaped [Ag(6)](4+) cluster, TBA(8)[Ag(6)(γ-H(2)SiW(10)O(36))(2)]·5H(2)O, could be synthesized, and the molecular structure was determined.

In studies of manganese deficiency in the rabbit,1 a method for the determination of this element in small samples of blood serum and other tissues was needed. The most promising of the organic reagents suitable for manganese appeared to be 4,4’-tetramethyldiaminodiphenylmethane, which has been used by Harry (1) in a calorimetric procedure and by Mellan (2) as a spot test reagent. Preliminary t...

UDP-GlcNAc (UDP-N-acetylglucosamine) and UDP-GlcA (UDP-glucuronic acid) were oxidized by periodate in the ribose ring and utilized as inhibitors for hyaluronate synthase in membrane fractions from the B6 cell line and in cell cultures of B6 cells and human fibrosarcoma HT 1080. Inhibition was irreversible and concentration-dependent and could be prevented in the case of periodate-oxidized UDP-G...

A rapid, simple, precise and accurate method is proposed for the determination of ternary mixtures of periodate-iodate-bromate based on their reaction with iodide ion at different pH values. The absorbance was measured at 352 nm. Three sets of reaction conditions were developed. In the first set of conditions, only periodate reacted with iodide, but in the second set the periodate and iodate re...

Water-soluble sulfonated cellulose (SC) samples were synthesized by oxidizing hardwood kraft pulp with sodium periodate followed by the sulfonation reaction with sodium bisulfite. Six levels of oxidation/sulfonation were obtained by using different mmols (0.93-4.67) of periodate per gram of pulp. The aldehyde and sulfonic acid contents, surface morphology, and water solubility property of these...

Magnetic nanoparticles-supported quaternary ammonium and phosphonium salts were prepared and evaluated as phase-transfer catalysts. Some of them exhibited good activities that were comparable to that of tetra-n-butylammonium iodide. The catalysts were readily separated using an external magnet and reusable without significant loss of their catalytic efficiency.

The molecular mechanism of action of the antitumor drug, methylthioinosine periodate oxidation product, was demon strated. This periodate oxidation product (methylthioinosinedicarboxaldehyde) inhibited bovine pancreatic ribonuclease A. The inhibition was due to Schiffs base formation with e-amino groups of lysine residues, one of which was in close proximity to the catalytic center of the enzyme.

2D Perovskites In article number 2100495, Hua Yu, Xueqing Xu, and co-workers introduced the mixed organic spacer cation n-butylammonium (BA) 1-naphthalenemethylammonium (1-NMA) in perovskites to manipulate interlayer interactions between bulky cations inorganic slabs, leading an efficient air-stable perovskite solar cell.
