Co-Mo/γ-Al2O3 catalysts with different pore shapes were synthesized for the ex situ upgrading of extra heavy oils by hydrodesulfurization (HDS), hydrodemetallization (HDM), and hydrodeasphaltization (HDA). The using aluminum oxides that prepared various methods. It was found product obtained thermochemical activation gibbsite leads to formation slit-shaped pores in oxide, while application hydr...

To identify the actual substrate of the glutathione-dependent sulfur dioxygenase (EC 1.13.11.18) elemental sulfur oxidation of the meso-acidophilic Acidithiobacillus thiooxidans strains DSM 504 and K6, Acidithiobacillus ferrooxidans strain R1 and Acidiphilium acidophilum DSM 700 was analysed. Extraordinarily high specific sulfur dioxygenase activities up to 460 nmol x min(-1) (mg protein)(-1) w...

Chlorella pyrenoidosa Chick (Emerson strain 3) utilizes thiosulfate for growth as effectively as sulfate, and more effectively than a variety of organic sulfur compounds containing sulfur in various oxidation states. Thiosulfates, differentially labeled with (35)S in either the SH- or SO(3) - sulfur moieties, were used to follow the incorporation of thiosulfate-sulfur into constituents of the i...

Dewatered sludges and biosolids generated from wastewater treatment facilities are known to emit malodorous odors causing public inconvenience. The odors typically comprise of reduced organo sulfur based compounds and nitrogen containing compounds. Lime stabilization is a technique which is commonly used in the wastewater industry to produce biosolids having reduced odors that can be safely lan...

Solid oxide fuel cells (SOFCs) are a rapidly emerging energy technology for a low carbon world, providing high efficiency, potential to use carbonaceous fuels, and compatibility with carbon capture and storage. However, current state-of-the-art materials have low tolerance to sulfur, a common contaminant of many fuels, and are vulnerable to deactivation due to carbon deposition when using carbo...

The addition of various nucleophiles to a vinyl 1,2,4-oxadiazole is described. Following optimisation, individual protocols tuned for the use of each specific class of reagent have been developed to allow the installation of nitrogen, sulfur, oxygen, and carbon nucleophiles, and leading to the preparation of a series of compounds containing the pharmaceutically important oxadiazole motif.

SW-163C and E are novel antitumor antibiotics, which belong to quinomycin family, isolated from the culture broth of Streptomyces sp. SNA15896. These compounds were determined to be cyclic depsipeptides having 3-hydroxyquinaldic acid as a chromophore and a sulfur-containing intramolecular cross linkage through various spectroscopic analyses.
