Fucosylated chondroitin sulfates are complex polysaccharides extracted from sea cucumber. They have been extensively studied for their anticoagulant properties and have been implicated in other biological activities. While nuclear magnetic resonance spectroscopy has been used to extensively characterize fucosylated chondroitin sulfate oligomers, we herein report the first detailed mass characte...

Aqueous Zinc-Ion Batteries In article number 2203542, Chuan Wu, Ying Bai, and co-workers develop a unique strategy to achieve aqueous Zn metal anodes with long lifespan, deep plating/stripping ability high current tolerance. A microporous artificial layer alleviates the side reactions by repelling sulfate groups, inducing deposition preferred orientation homogenizing ion flux dendrite-free morp...

In the title compound, [Zn(SO4)(C12H8N2)2]·C3H8O2, the Zn(II) ion is in a distorted square-pyramidal coordination environment composed of four N atoms from two chelating 1,10-phenanthroline ligands and one O atom from a monodentate sulfate ligand. The Zn(II) ion lies on a twofold rotation axis. The sulfate ligand and propane-1,2-diol mol-ecules are disordered across the twofold rotation axis. T...

Fine aerosol particles were analyzed by time-of-flight secondary ion mass spectrometry with high lateral resolution. After sulfate particles with a diameter of about 1 μm were sputtered by gallium primary ions (a gallium focused ion beam), solid materials with a diameter of about 100 nm were occasionally found inside the particles. Since the mass spectrum for the solid material was almost the s...

With the objective of developing an odorless biodegradation process for dimethyl sulfoxide (DMSO), Hyphomicrobium sp. WU-OM3 was isolated. During the cultivation of strain WU-OM3 cells with 20 mM dimethyl sulfone (DMSO2) as the sole carbon source, DMSO2 was completely consumed within 48 h and sulfate ion accumulated in the culture broth. Methanesulfonate was also detected as an intermediate of ...

The biodegradable polysaccharide chitosan possesses protonated and natural amino groups at medium pH values and has therefore been used as an adsorbing material for nickel salts in water treatment. Nickel is a problematic heavy metal ion which can cause various diseases and disorders in living organisms. Here, we show the influence of oxyanions (e.g., nitrate and sulfate) to the adsorption of n...

A sulfate-encapsulating complex, [Cu(1)L(6)]·3[Cu(2)L(2)(DMF)(4)](SO(4))(4) (1, L = N-(1-naphthyl)-N'-(3-pyridyl)urea) is synthesized in which two C(3)-clefts of the octahedral complexes interdigitate to form a cavity to encapsulate the sulfate ion by six urea groups.

Sulfate is bound firmly to Salmonella typhimurium. The binding ability is repressible. The binding site is located near the cell surface, and has been suggested as playing a role in active transport of sulfate. A simple procedure for obtaining the sulfate-binding material in homogeneous form is reported here. The material has a molecular weight of 32,000 and is of typical amino acid composition...
