ZnO and SnO2-doped ZnO nanoparticles were prepared by a sol–gel method for the first time. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the ZnO and SnO2-doped ZnO samples. Advanced oxidation processes (AOPs) have proved very effective in treatment of the various hazardous organic pollutants such as surfactants and pharmaceuticals...

The paper reports the preparation and photocatalytic activity of ZnO doped SnO2 nanoparticles. These nanoparticles were synthesized by hydrothermal method. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Their grain sizes are about 50-100 nm. The characterization results revealed that the synthesized nanoparticles possess just cr...

This study is an investigation of high-humidity aging effects on the total volatile organic compound (T-VOC) gas-sensing properties of platinum, palladium, and gold-loaded tin oxide (Pt,Pd,Au/SnO(2)) thick films. The sensor responses of the high-humidity aged Pt,Pd,Au/SnO(2), a non-aged Pt,Pd,Au/SnO(2), and a high-humidity aged Pt/SnO(2) to T-VOC test gas have been measured. The high-humidity a...

Tin oxide thin films were deposited on the R-cut sapphire substrate by the electron-beam evaporation of a ceramic SnO2 source. X-ray diffraction and transmission electron microscopy studies revealed that the films deposited at lower temperatures were amorphous while those grown at temperatures above 350◦C consisted of the α-SnO phase with the PbO type structure. Epitaxial α-SnO films on the R-c...

A nanoscale coating of a Si layer on the pore walls of SnO(2) nanotubes (Si-coated SnO(2)) leads to very good electrochemical performance in coulombic efficiency, rate capability and capacity retention compared with untreated SnO(2) nanotubes.

Nitric oxide (NO) effects are often mediated via S-nitrosothiol (SNO) formation; SNO uptake has recently been shown to be mediated in some cell types via system L-type amino acid transporters (LAT-1, 2). Inhaled NO therapy may exert some biological effects via SNO formation. We therefore sought to determine if pulmonary epithelial SNO uptake depended on LAT or peptide transporter 2 (PEPT2). Bot...

It is proposed that the bond between nitric oxide (NO) and the Hb thiol Cys-beta(93) (SNOHb) is favored when hemoglobin (Hb) is in the relaxed (R, oxygenated) conformation, and that deoxygenation to tense (T) state destabilizes the SNOHb bond, allowing transfer of NO from Hb to form other (vasoactive) S-nitrosothiols (SNOs). However, it has not previously been possible to measure SNOHb without ...

A novel heterostructure is developed by grafting 1D SnO(2) nanorods onto both sides of pre-grown 2D Fe(2)O(3) nanoflakes, forming a comb-like rather than tree-like branched nanostructure. The SnO(2) nanorod branches are determined to grow along the [001] direction on the (±001) planes of Fe(2)O(3) nanoflakes. The resulting SnO(2)@Fe(2)O(3) nanocombs show stabilized cycling performance and impro...
