We report that vertically aligned molybdenum (Mo) nanowalls can grow on various substrates by simple thermal vapor deposition. Individual nanowalls have a typical thickness of about 50 nm and very good conductivity with a typical average value of about 1.97 × 104 Ω-1 cm-1, i.e., only an order of magnitude less than the value of bulk Mo. The formation process is characterized in detail, and it i...

GaSb inversion-mode PMOSFETs with atomiclayer-deposited (ALD) Al2O3 as gate dielectric are demonstrated. A 0.75-μm-gate-length device has a maximum drain current of 70 mA/mm, a transconductance of 26 mS/mm, and a hole inversion mobility of 200 cm/V · s. The OFF-state performance is improved by reducing the ALD growth temperature from 300 ◦C to 200 ◦C. The measured interface trap distribution sh...

Silver deposited titania (Ag/TiO2) nanocomposite thin films were fabricated by the simple sonochemical deposition of Ag on preformed aerosol-assisted chemical vapor deposited TiO2 thin films. The photelectrocatalytic performance of a newly fabricated Ag/TiO2-modified photoelectrode was studied for methanol oxidation under simulated solar AM 1.5G irradiation (100 mW/cm2). The Ag/TiO2-modified ph...

Low turn-on field of 2.3 V/µm was found for the emission current density of 10 µA/cm2 from 2D porous ZnO nanosheets. High current density of 0.76 mA/cm2 was drawn at an applied field of 4.1 V/µm. The observed low turn-on field of porous ZnO nanosheets has been found to be superior to the other ZnO nanostructures reported in the literature. Also, the emission current stability over a period of 3...

In this study, Chemical Oxygen Demand (COD) removal efficiency from wood processing wastewaters by Fenton Process (FP) and Photo Electro (PEFP) were examined. Important operating parameters such as pH, Fe+2 concentration/(amper for PEFP), H2O2 concentration reaction time optimized. Optimum operation conditions of the FP pH 3.5, 1.4 gr/L Fe2+ 50 150 min. while they 3.00, 9.99 mA/cm2 current dens...

When applied within a low-strength electric field (+/- 12 V/cm) with a low current density (+/- 2.1 mA/cm2), several industrial biocides exhibited enhanced killing action against Pseudomonas aeruginosa biofilms grown on stainless steel studs. Biocide concentrations lower than those necessary to kill planktonic cells of P. aeruginosa (1, 5, and 10 ppm of the active ingredients of kathon, glutara...

Photoanodes comprising Au nanoparticles (GNPs) and thin TiO2 layers with a stacked structure were fabricated by repeating the application of TiO2 paste and GNP solutions on conductive glass to vary the distribution of GNPs in the TiO2 layer. The plasmon-enhanced characteristics of dye-sensitized solar cells (DSSCs) with such photoanodes were investigated. Both the absorption of the TiO2 layer a...

The aim of the present study was to develop and investigate the feasibility of delivering Nebivolol as a transdermal patch by iontophoresis. The passive and electrically assisted transdermal delivery of Nebivolol hydrochloride by iontophoresis will improve the therapeutic efficacy and overcome the difficulties raised in oral drug delivery. Because of its extensive hepatic metabolism and low dos...

Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...

In this paper, the performance of Fe-based redox flow batteries (IRFBs) was dramatically improved by coating N-doped carbon spheres (NDCS) on graphite felt electrodes. NDCS synthesized single-step hydrothermal method using dextrose and ammonia as a precursor coated over electrodes electrostatic spraying. The weight required for modification electrode to achieve effective battery studied electro...
