The absorption spectra of the mixture of SO2 and CO2 at different partial pressures of both gases have been recorded at room temperature in the 4 µm region using the Bruker IFS 125 HR FTIR spectrometer. The multispectrum fitting procedure has been applied to these spectra to recover the CO2-bro...

Renowned for its high theoretical specific energy, lithium-sulfur (Li–S) batteries still suffer from the shuttle effect of polysulfides, the insulating nature of sulfur and severe volumetric variations, especially for cathodes with high sulfur contents. Herein, S microsphere encapsulated within...

Being lack of core data and measured data, although the marine oil & gas exploration in the South Yellow Sea Basin has been going on for 57 years, no commercial hydrocarbon reservoirs have been found so far. The quantitative source rocks evaluation based on geochemical data and fluid inclusions ...

The conformational, magnetic and electronic study of one and two sulfur atoms doping on multivacancy graphene systems, using first principles calculations is presented. The location for the addition of the sulfur atoms is ruled by the presence of pentagonal figures in the optimized multivacancy ...

Double metal phosphide NiCoP with hollow quasi-polyhedron structure was rationally designed and synthesized via acidic etching, precipitation of ZIF-67 polyhedra and further phosphorization treatment. The outer and inside shells of the hollow quasi-polyhedral structure were formed by many interc...

Sulfur adsorption on gold surfaces has been extensively studied because of the key role of sulfur species in heterogeneous catalysis, and, more recently, due to the interest in the synthesis of anisotropic gold nanoparticles with potential applications in medicine that involves sulfide reduction...

The CO2/CH4 adsorption behaviors in brown coal at the temperatures of 298, 313, and 373 K and in the pressure range of 0.005–10 MPa were investigated by molecular dynamics (MD), density functional theory (DFT), and grand canonical Monte Carlo (GCMC) simulations. The absolute adsorption isotherm...

Sulfur transformation and distribution during pyrolysis of an industrial coking coal blend with a high organic-sulfur fat coal was studied in a fixed-bed reactor. Sulfur K-edge X-ray absorption spectroscopy was used to study the sulfur speciation in cokes. Two coals with high volatiles were sele...

The thioflavine S technique for delineating blood flow patterns in central nervous system tissue has been reviewed. Electron microscopic studies of the microvasculature of the feline spinal cord after intravascular administration of the thioflavine S demonstrated no fine structural alterations i...

Blocking a selected wavelength range from the light spectrum can have multiple benefits. Ultra-violet (UV) radiation is detrimental to the retina, necessitating its blocking through sunglasses and contact lenses. The near-visible light also has enough energy to cause damage but, is typically not...

Molecular surrounding environment is one of the important factors that can modify nonlinear properties of materials. For precise investigation, in this paper, single beam Z-scan technique was used for measuring the third order nonlinear responses of Basic Blue 55 molecules in different solvent m...

Acetan is an anionic bacterial polysaccharide. The chemical repeat unit consists of a cellobiose unit solubilished by attachment of a charged pentasaccharide sidechain to one of the glucose residues. The repeat unit contains two sites of acetylation. 1H and 13C NMR studies, coupled with both bas...

Novel aceQ and aceR genes involved in the acetan biosynthesis of Acetobacter xylinum were newly isolated. The homology search with DNA Data Bank of Japan indicated that aceQ and aceR were glycosyltransferases. Their gene-disrupted mutants were obtained by homologous recombination using the tetra...

Kozakia baliensis NBRC 16680 produces a heteropolysaccharide (HePS), whose biosynthesis is similar to the biosynthesis of the exopolysaccharide acetan. To elucidate structural components and macromolecular properties of this HePS, we carried out methylation analysis, NMR spectroscopy, rheologica...

Twenty-four stereoisomers of 5-amino- and 5-amino-C-(hydroxymethyl)-1,2,3,4-cyclopentanetetraols and twenty-six of the corresponding N-phenyl cyclic isourea derivatives were assayed for inhibitory activity against six glycosidases. Among them, as has been expected for structure mimics of putativ...

IntroductionSeveral studies have reported increased oxidation of lipids, proteins and DNA in the brains of patients with Alzheimer disease (AD). Moreover, these patients display differences in the activity and polymorphisms of the genes encoding the enzymes GST (T1, M1) and MnSOD. For these reas...

The effects of the neurokinin NK2 receptor agonist [Lys5,MeLeu9,Nle10]-NKA(4–10) (LMN-NKA) on bladder and colorectal function were examined in minipigs. In anesthetized animals, subcutaneous (SC) administration of 30–100 μg/kg increased peak bladder and colorectal pressures. Increases in blad...

The application of manure may result in contamination of the environment with antimicrobials, antimicrobial-resistant bacteria, resistance genes and plasmids. The aim of this study was to investigate the impact of the administration of colistin and of manure management on (i) the presence of col...

Rheological measurements as a function of temperature have been carried out on a micellar-ionic liquid (4.45 wt% sodium dodecylsulfate (SDS) in 1-butyl-3-methylimidazolium chloride (BmimCl)) with 18.7 wt% lithium chloride (LiCl). We report here for the first time, the formation of a “weak gel”...

Heterocyclic compounds containing pyrazolyl-oxopropyl-quinazolin-4(3H)-one are reported to possess significant biological activity. Syntheses of 6-bromo-2-(3-chloro-2-oxopropyl)-3-(4-fluorophenyl)quinazolin-4(3H)-one 2 6-bromo-3-(4-fluorophenyl)-2-(3-hydrazinyl-2-oxopropyl)quinazolin-4(3H)-one 3...
