Abstract In this work, CuO-loaded tetragonal SnO 2 nanoparticles (CuO/SnO NPs) were synthesized using precipitation/impregnation methods with varying Cu contents of 0–25 wt% and characterized for H S detection. The material phase, morphology, chemical composition, specific surface area NPs evaluated X-ray diffraction, transmission electron microscopy, scanning energy-dispersive spectroscopy, ph...

Protein S-nitrosation (SNO-protein), the nitric oxide-mediated posttranslational modification of cysteine thiols, is an important regulatory mechanism of protein function in both physiological and pathological pathways. A key first step toward elucidating the mechanism by which S-nitrosation modulates a protein's function is identification of the targeted cysteine residues. Here, we present a s...

We report the analysis of a 36-kbp region of the Neurospora crassa genome, which contains homologs of two closely linked stationary phase genes, SNZ1 and SNO1, from Saccharomyces cerevisiae. Homologs of SNZ1 encode extremely highly conserved proteins that have been implicated in pyridoxine (vitamin B6) metabolism in the filamentous fungi Cercospora nicotianae and in Aspergillus nidulans. In N. ...

Different compositions of Eu doped electrodes were prepared by a pyrolysis method in order to investigate the effect of Eu on the electro-catalytic behavior of Ti-based SnO(2)/Sb electrodes. The electrodes were characterized by SEM, EDS, XRD and their degradation abilities were evaluated using phenol. The electro-catalytic performance of prepared electrodes was strongly influenced by the heat-t...

Polymeric/inorganic nanocomposite films have been fabricated through a combination of flame-spray-pyrolysis (FSP) made inorganic scaffold and surface initiated polymerization of cyanoacrylate. The highly porous structure of pristine SnO(2) films allows the uptake of cyanoacrylate and the polymerization is surface initiated by the water adsorbed onto the SnO(2) surface. Scanning electron microsc...

The role of S-nitrosated hemoglobin (SNO-Hb) in the regulation of blood flow is a central and controversial question in cardiopulmonary physiology. In the present study, we investigate whether intact human red blood cells (RBCs) synthesized to contain high SNO-Hb levels are able to export nitric oxide bioactivity and vasodilate the pulmonary circulation, and whether SNO-Hb dependent vasodilatio...

We studied the structural behavior and electrical transport properties of epitaxial a-SnO thin films grown on the (1̄012) a-Al2O3 ~sapphire! substrate. Hall effect measurements revealed that the epitaxial as-deposited SnO film is a p-type semiconductor. In situ x-ray diffraction studies show that the a-SnO phase is metastable and will transform into SnO2 with the rutile type structure when annea...

We report a new photoanode for flexible dye sensitized solar cells based on a judicious combination of SnO(2) nanoparticles and ZnO nanotetrapods and the development of an effective low temperature fabrication technique of "acetic acid gelation-mechanical press-ammonia activation". A 4.91% efficiency has been achieved on an ITO-coated polyethylenenaphthalate (ITO/PEN) substrate under 1 sun equi...
