The current study both synthesizes and uses four compounds of graphene oxide (GO), nitrogen doped graphene oxide (ND-GO), high nitrogen doped graphene oxide (HND-GO), and three dimensional high nitrogen doped graphene oxide (3D-HND-GO) in order to remove a model anionic dye, Congo red (CR) from wastewaters. It also compares their carbon nano-structure, with regard to removal efficiency and find...

Nitrous oxide has been recognized as a product of denitrifying organisms since the early work of Gayon and Dupetit (1882a, b; 1886). Under some conditions it can be the major initial product (Wijler and Delwiche, 1954). Kluyver and Verhoeven (1954) have investigated the production of nitrous oxide by a large number of denitrifiers and conclude that its production and utilization is characterist...

The effect of nitrogen (N14) implant into dual-doped polysilicon gates was investigated. The electrical characteristics of sub-0.25m dual-gate transistors (both pand n-channel), MOS capacitor quasi-static C V curve, SIMS profile, poly-Si gate Rs, and oxide Qbd were compared at different nitrogen dose levels. A nitrogen dose of 5 10 cm 2 is the optimum choice at an implant energy of 40 KeV in te...

BACKGROUND The endothelium-derived relaxing factor has been shown to be nitric oxide or a related nitroso compound, synthesized by the enzyme nitric oxide synthetase, which oxidizes the guanidono nitrogens of arginine. This enzyme is activated by increases in cytosolic calcium. The effect of the clinically used calcium channel antagonists on this process is controversial. The present study was ...

The paper presents the results of investigations on resistance structures based on graphite oxide (GRO) and graphene oxide (rGO). The subject matter of the investigations was thaw the sensitivity of the tested structures was affected by hydrogen, nitrogen dioxide and carbon dioxide. The experiments were performed at a temperature range from 30 °C to 150 °C in two carrier gases: nitrogen and syn...

Hydrogen-dependent evolution of methane from salt marsh sediments and whole-cell suspensions of Methanobacterium thermoautotrophicum and Methanobacterium fornicicum ceased or decreased after the introduction of nitrate, nitrite, nitric oxide, or nitrous oxide. Sulfite had a similar effect on methanogenesis in the whole-cell suspensions. In salt marsh sediments, nitrous oxide was the strongest i...

1. Nitric oxide that was produced by reducing nitrite with an excess of acidified potassium iodide under nitrogen in Warburg respirometer flasks was rapidly absorbed by a solution of permanganate in sodium hydroxide held in the side arm. A small amount of nitrous oxide (or nitrogen) that was also produced was not absorbed. 2. By using a quantitative method for the recovery of nitrite from sampl...

The nitrogen concentration of ultrathin gate oxides (sub-1.3 nm) was varied in a wide range (from 13 % to 23 %). The threshold voltage and the channel carrier mobility of advanced 65 nm technology CMOSFET transistors fabricated with these oxides were analyzed. It was observed that increasing the nitrogen concentration in the gate oxide results in a negative shift of the threshold voltage for bo...
