Staphylococcus aureus is a commensal human pathogen and a major cause of nosocomial infections. As gaseous signaling molecules, endogenous hydrogen sulfide (H2S) and nitric oxide (NO·) protect S. aureus from antibiotic stress synergistically, which we propose involves the intermediacy of nitroxyl (HNO). Here, we examine the effect of exogenous sulfide and HNO on the transcriptome and the format...

Objective: The purpose of this study was to develop a novel colorimetric system for direct detection of hydrogen sulfide on the tongue dorsum from subjects with complaints of halitosis. Method: An assay system comprised of a cotton swab impregnated with zinc sulfate, attached chromatography paper, stabilizing solution, and coloring reagents for the methylene blue technique was developed. Using ...

ZnS  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  In  this  synthesis, thioacetamide  was  used  as sulfur  source.  The effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  The nanostructures  were  characterized  by ...

The title compound, [ZnI(2)(C(10)H(8)N(2)S)], contains a six-membered chelate ring adopting a boat conformation in which the Zn atom is coordinated by two iodide ions and by the two pyridyl N atoms of a single di-2-pyridyl sulfide ligand within a slightly distorted tetra-hedron. The Zn, S and I atoms are located on a crystallographic mirror plane. As usual for this type of complex, the sulfide ...

The molecule of the title compound, [ZnBr(2)(C(10)H(8)N(2)S)], contains a six-membered chelate ring in a boat conformation in which the Zn atom is coordinated by two Br atoms and by the two pyridyl N atoms of a single di-2-pyridyl sulfide (dps) ligand within a slightly distorted tetra-hedron. The dihedral angle between the pyridine rings is 52.7 (1)°. As is usual for this type of complex, the s...

Copper indium gallium sulfide, CuIn1-xGaxS2 (CIGS2) solar cells prepared with chemical bath deposited heterojunction partner zinc-cadmium sulfide (ZnxCd1-xS) layer has exhibited better blue photon response and in turn, higher currents. This can be attributed to its higher bandgap than that of CdS. The open circuit voltages for CIGS2/ZnxCd1-xS were also higher than those of the CIGS2/CdS devices...

We have performed a rigorous investigation of the structure and composition of individual grains in copper-zinc-tin-sulfide (CZTS) films realized by sulfurization of a sputtered metal stack. Although on average close to the ideal CZTS stoichiometry, elemental analysis shows significant grain-to-grain variations in composition. High-resolution Raman spectroscopy indicates that this is accompanie...
