Peptidylglycine monooxygenase (PHM) catalyzes the final step in the biosynthesis of amidated peptides that serve as important signaling molecules in numerous endocrine pathways. The catalytic mechanism has attracted much attention because of a number of unique attributes, including the presence of a pair of uncoupled copper centers separated by 11 Å (termed CuH and CuM), an unusual Cu(I)SMet in...

In this paper CuFe2O4, nanocrystalline powders were prepared. Also, the supported Cu ferrite was obtained by impregnation of the supports with Cu and Fe nitrates solutions, for calcination temperature 450 ºC. The samples were characterized by X-ray powder diffraction (XRD) and Fourier transform-infrared spectroscopy (FT-IR). Photocatalytic degradation of acid red 206 in water was studied. CuFe2...

Abstract: materials can be fabricated by sintering of W-Cu composite powders. In this research W-20%wt Cu composite powderswas synthesized via a co-precipitation method. Precipitate obtained from a mixture of copper nitrate and ammoniumparatungstate (APT) in distilled water contained W-Cu compounds. This precipitate was washed, dried and calcinedat 550 of dried precipitate powder was determined...

This research was carried out to determine the levels of Cd, Hg, Pb, As, Al, Cu, Fe and Zn in muscles Trachurus mediterraneus ponticus. The fish samples were collected from Samsun coasts Black Sea between September December both 2021 2022 analysed by using Inductively Coupled Plasma Mass Spectrophotometer. metal values muscle tissues horse mackerel below permissible values. has higher mean conc...

New lead volatilisation rate and activity data in copper mattes containing low levels of Pb were determined through high-temperature experiments. Measurements on from (Cu-Fe-S) carried out at temperatures 1200 to 1570°C by injection nitrogen into shallow baths. The concentration the melts covered a range 200–6 mg.kg−1. exhibited first order behaviour with respect Pb. deduced vapour pressure gas...

to understand the present status of metal contamination along the haiphong-halong coast, the concentrations of as, cd, cr, cu, pb, and zn were seasonally determined in rock oysters from four sites during 2013. the results indicated that a high concentration of heavy metals was found in oysters. the average concentrations of zn and cu were extremely high, ranging from 823.6–3201.6 and 238.1–1597...

The water–gas-shift (WGS) reaction was studied on a series of supported Cu catalysts in which the MgAl2O4 (MAO) support modified by depositing ZnO, CeO2, Mn2O3 and CoO using Atomic Layer Deposition (ALD). Addition one ALD cycle gave rise to with nominally 1-wt% Cu. A 1.1-wt% Cu/MAO catalyst prepared exhibited twice dispersion but ten times WGS activity impregnation, implying that is structure s...

A survey was conducted in certain parts of Haryana to record the prevalence of micro mineral deficiency in buffaloes. The prevalence of soil Cu, Co, Zn and Fe deficiency was 55.26%, 6.9%, 59.12% and 7.89% respectively. While that of fodder Cu, Co, Zn and Fe was 60.64%, 6.7%, 61.22% and 11.37% respectively. The overall prevalence of serum Cu, Co, Zn and Fe deficiency in Haryana was 59.2%, 19.1%,...
