An experimental program was conducted to determine the mechanisms by which phosphorus affects the corrosion and passi~ation behavior of F e Cr P alloys, "lb idcnti~ separately the ell~cts of structure and chemistry on the corrosion behavior, thin tilms of Fe--ItK'r-xP 10 < x < 35 at.%) were I~-epared by ion beam mixing. Films with a phosphorus content greater than approximately 20 at.% were fou...

in this study, nickel-phosphorus coating was prepared by electrodeposition technique on the 304 stainless steel substrate. the effects of current density, phosphorous acid concentration, time and ph on the phosphorous content was investigated using taguchi method. a uniform amorphous-nanocrystalline structure (ni-12%p) was obtained. sem, eds, tem and xrd were used in order to study the surface ...

The abundance and relevance ofAccumulibacter phosphatis (presumed to be polyphosphate-accumulating organisms [PAOs]), Competibacter phosphatis (presumed to be glycogen-accumulating organisms [GAOs]), and tetrad-forming organisms (TFOs) to phosphorus removal performance at six full-scale enhanced biological phosphorus removal (EBPR) wastewater treatment plants were investigated. Coexistence of v...

The phosphate sorption capacity of intertidal vegetated marsh sediments was measured along a salinity gradient in the Cooper River estuary, South Carolina. The phosphate sorption capacity of the surface sediments (0–10 cm) of a freshwater marsh was higher than the sorption capacity of sediments from brackish and saline marshes, and surface sediments had greater sorption capacity than subsurface...

The presented results expand the understanding of normal chemical composition body. study was carried out on basis a pig-breeding farm in Altai Territory 2016-2020 clinically healthy 6-month-old pigs Landrace breed. Chemical analysis pig bristles performed by inductively coupled plasma atomic emission spectrometry. data were processed using Statistica 8 software (StatSoft Inc., USA). A correlat...

Urban surface water runoff typically contains high but varying amounts of organic matter and nutrients that require removal before reuse. Infiltration systems such as sunken lawns can improve water quality. However, there is currently insufficient information describing the treatment efficiency of lawn-based infiltration systems. In this study, novel sunken lawn infiltration systems (SLISs) wer...

A radial p-n junction solar cell based on vertically free-standing silicon nanowire (SiNW) array is realized using a novel low-temperature and shallow phosphorus doping technique. The SiNW arrays with excellent light trapping property were fabricated by metal-assisted chemical etching technique. The shallow phosphorus doping process was carried out in a hot wire chemical vapor disposition chamb...

Plasma-enhanced chemical vapor deposition phosphorus-doped silicon oxynitride SiON layers with a refractive index of 1.505 were deposited from N2O, 2% SiH4/N2, NH3, and 5% PH3/Ar gaseous mixtures. The PH3/Ar flow rate was varied to investigate the effect of the dopant to the layer properties. We studied the compositions and the chemical environment of phosphorus, silicon, oxygen, nitrogen, and ...

Prediction of phosphorus (P) availability from soil-applied composts and manure is important for agronomic and environmental reasons. This study utilized chemical properties of eight composted and two non-composted beef cattle (Bos taurus) manures to predict cumulative phosphorus uptake (CPU) during a 363-d controlled environment chamber bioassay. Ten growth cycles of canola (Brassica napus L.)...

We show how high-resolution NMR spectra can be obtained for solids for which the spectra are normally broadened due to structural disorder. The method relies on correlations in the chemical shifts between pairs of coupled spins. It is found experimentally that there are strong correlations in the chemical shifts between neighboring spins in both phosphorus-31 and carbon-13 spectra. These correl...
