background: polychlorinated biphenyls (pcbs) are occupational and environmental pollutants and hazardous organic compounds that have created major environmental and occupational challenges. pcb compounds have different health effects in humans depending on sex, age, route of entry, intensity, and frequency of exposure. this study was conducted to determine the effect of microwave rays, hydrogen...

Dye-sensitized solar cells (DSSCs) are fabricated using a novel 3C-SiC/TiO(2) nanocomposite as a photoelectrode to enhance the power conversion efficiency. Compared with a pristine nanocrystalline TiO(2) cell, a DSSC based on a 3C-SiC (0.04 wt%)/TiO(2) nanocomposite photoelectrode shows ~115% increase in power conversion efficiency.

TiO(2) loading Pt nanoparticles (Pt@TiO(2)) promote one-pot synthesis of imines from alcohols and amines under UV irradiation at room temperature. This is achieved via a Pt-assisted photocatalytic oxidation of alcohols and a catalytic condensation of the formed aldehydes with amines on the TiO(2) surface.

TiO(+)(CO(2)) is produced by reaction of laser-ablated titanium atoms with CO(2) and subsequent clustering, supersonically cooled, and its electronic spectroscopy was characterized by photofragment spectroscopy, monitoring loss of CO(2). The photodissociation spectrum consists of a vibrationally resolved band in the visible, with extensive progressions in the covalent Ti-O stretch (952 cm(-1) v...

TiO(2) films composed of flower-like TiO(2) microspheres with exposed {001} facets were synthesized by a simple one-pot hydrothermal method and exhibited tunable photocatalytic selectivity towards decomposition of azo dyes in water by modifying the surface of TiO(2) microspheres as well as by varying the degree of etching of {001} facets.

Selective local N-doped TiO(2) electrodes were fabricated using a pulsed laser deposition method. Different from the uniform nitrogen-doping in TiO(2) electrodes showing the diminution of IPCE in the UV light region, the inner nitrogen-doped TiO(2) electrode uniquely enhanced IPCE in the UV light region significantly (up to 95% at 320 nm, 1.23 V vs. SHE).

BACKGROUND Morning symptoms associated with COPD have a negative impact on patients' quality of life. Long-acting bronchodilators with rapid onset may relieve patients' symptoms. In the Symptoms and Pulmonary function in the moRnING study, we prospectively compared the rapid onset bronchodilator profile of glycopyrronium (GLY) and tiotropium (TIO) during the first few hours after dosing in pati...

Evaluation of the potential hazard of man-made nanomaterials has been hampered by a limited ability to observe and measure nanoparticles in cells. In this study, different concentrations of TiO(2) nanoparticles were suspended in cell culture medium. The suspension was then sonicated and characterized by dynamic light scattering and microscopy. Cultured human-derived retinal pigment epithelial c...

Conductive core-sheath TiO(2)-PEDOT nanocables were prepared using electrospun TiO(2) nanofibers as template, followed by vapor phase polymerization of EDOT. Various techniques were employed to characterize the sample. The results reveal that the TiO(2) core has an average diameter of ∼78 nm while the PEDOT sheath has a uniform thickness of ∼6 nm. The as-prepared TiO(2)-PEDOT nanocables display...
