RF plasma was applied for the reduction of human blood and bovine blood in which essential proteins to lives were included. Atomic oxygen and singlet molecular oxygen are significantly important for the treatment of protein by RF oxygen plasma. The reduction rate of the protein was analysed by FTIR spectra, and the light emitted from oxygen plasma was detected by spectrometer. The ratio of emis...

Molecular oxygen and non-heme iron proteins (NHIPs) are that have an atom bound to one or more atoms, found in bacteria, archaea, some eukaryotes. NHIPs involved a variety of biological processes, such as respiration, electron transfer, catalysis. They can be categorized into two classes: cytochrome proteins, which oxygenases, catalyze the oxidation substrates by utilizing molecular oxygen. cri...

The formation of molecular oxygen from water in photosynthesis is catalyzed by photosystem II at an active site containing four manganese ions that are arranged in di-mu-oxo dimanganese units (where mu is a bridging mode). The complex [H2O(terpy)Mn(O)2Mn(terpy)OH2](NO3)3 (terpy is 2,2':6', 2"-terpyridine), which was synthesized and structurally characterized, contains a di-mu-oxo manganese dime...

The aerobic oxidation of alcohols was efficiently completed in high conversion and selectivity using Cu3/2[PMo12O40]/SiO2 as catalyst under mild reaction condition. This reaction provides a new environmentally friendly rout to the conversion of alcoholic function to carbonyl groups.

We have investigated the formation of ozone by electron impact in solid molecular oxygen ices between 11 and 30K. The amount of ozone formed is shown to be strongly dependent on the sample temperature. As the ice temperature increases, the column density of the ozonemonomer is found to diminish. This is ascribed to the loss of oxygen atoms by recombinationwith a neighboring oxygen atom to ‘‘rec...

Oxygen in air exists in a diatomic molecular form (O2, molecular weight [MW] 16 g/mol) that, at standard temperature and pressure, is a colorless, odorless gas. The diatomic molecular state is the form that we administer to our patients as a respiratory gas, either pure oxygen or in mixtures with air or helium (heliox), and is that form most commonly referred to as oxygen. While the gaseous sta...

collection of multiple processes that increase the chronological age of an organism leading to death is defined as aging, and even though important, it is poorly understood. recent research has shown that aging is due to biochemical and genetic changes, in interaction with environmental effects, including diet and nutrition. most knowledge on aging is based on ge­netic model system, but its mol...

the density functional theory (dft) and the natural bond orbital (nbo) calculations basedmethod b3lyp/6-31g were carried out to study the interaction of dopamine with carbon nanotube.the nanotube used in this study, includes 60 c atoms (6, 6) type. relative and formation energies ofcompounds, muliken charges, occupancy, the highest occupied molecular orbital (homo) and thelowest unoccupied mole...
