Dye sensitized solar cell was assembled using TiO2 nanoparticle with argon-nitrogen plasma treatment and CuBi2O4 sputtering electrode prepared by plasma irradiation. The electric property of the solar cell fabricated by plasma treated TiO2 nanoparticle was improved because the physical and chemical property of TiO2 particles affected from the nitrogen plasma treatment

Inflation of an automobile airbag is accomplished by converting sodium azide to nitrogen gas. The bags are vented so that nitrogen and residual byproducts of combustion, such as alkaline gas, are released into the passenger compartment. We report the case of a patient who incurred a chemical keratitis after the driver's-side airbag deployed. The importance of recognition and management is discu...

Synchrotron-based scanning transmission X-ray spectromicroscopy (STXM) was used to characterize the local chemical environment at and around the platinum particles in the membrane (PTIM) which form in operationally tested (end-of-life, EOL) catalyst coated membranes (CCMs) of polymer electrolyte membrane fuel cells (PEM-FC). The band of metallic Pt particles in operationally tested CCM membrane...

Enriched stable isotopes of many elements have been widely used in many aspects and such isotopes have been primarily used as the tracer for agricultural and biochemical studies and the availability of the isotopically labeled compounds have been now extensively increasing. Chemical exchange separation of isotopes is based on the equilibrium fractionation of isotopes between two phases, ion exc...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

An influence of nitrogen incorporation on the chemical composition, bonding structure, surface morphology and activity, adhesion strength, and corrosion resistance of platinum/ruthenium/nitrogen-doped diamond-like carbon PtRuN-DLC thin films deposited on conductive p-Si 100 substrates using dc magnetron sputtering deposition was investigated using X-ray photoelectron spectroscopy, micro-Raman s...

Many chemical models of dense interstellar clouds predict that the majority of gas-phase elemental nitrogen should be present as N(2), with an abundance approximately five orders of magnitude less than that of hydrogen. As a homonuclear diatomic molecule, N(2) is difficult to detect spectroscopically through infrared or millimeter-wavelength transitions. Therefore, its abundance is often inferr...

The spatial variation of soil physical and chemical properties in Funiu Mountain was studied to provide references for identifying soil spatial variation mechanism in bordering land of China warm temperate zone and northern subtropical region. Using vertical gradient sampling and traditional statistics method, the soil samples at the altitude from 1640 m to 1870 m were collected to compare phys...

Two field experiments were carried out to evaluate role and importance of cobalt under different levels of nitrogen on nodules efficiency, growth, yield, minerals composition and chemical characteristics of groundnut plants. The experiments were conducted at Research and Production Station, National Research Centre, El-Nobaria Beheara Governorate, DeltaEgypt, under drip irrigation system during...
