(2021-10-12)Copper is an essential trace element that can produce reactive oxygen species (ROS). Excess ROS promote oxidative stress, which can lead to hepatic injury. Copper-associated hepatopathy is well-studied in humans and dogs. ...
-
(2021-06-01)Low-molecular-mass (LMM) transition metal complexes are thought to play essential roles in metal ion trafficking, regulation, and signaling in biological systems. Their chemical identities remain largely unknown due to ...
-
(2019-03-18)Graphene and carbon nanotubes exhibit extraordinary and diverse properties, and therefore these nanomaterials are finding an increasing number of applications in many industries. However, the major obstacle in the integration ...
-
(2020-04-16)Copper is required for the assembly and activity of cytochrome c oxidase (CcO), the terminal enzyme of the mitochondrial respiratory chain. As a multi-subunit metalloprotein, CcO biogenesis involves many assembly factors ...
-
(2012-02-14)Sophisticated catalytically active sites of metalloenzymes provide inspiration to synthetic chemists, as the metal coordination environments are often atypical to those found on the chemist's benchtop. Furthermore, ...
-
(2009-05-15)Ultrafine grained (UFG), and nanocrystalline (nc) materials are of interest because of the high strength, compared with coarse grained counterparts. Several current methods to fabricate UFG and nc materials result in samples ...

(2009-05-15)This study was undertaken to compare the absorption and retention of copper and zinc when supplemented to exercising horses in the form of sulfate or organic-chelate mineral supplements. Nine mature horses were used in a ...
-
(1996)The objective of this research is to evaluate the performance of ZrB₂ infiltrated with copper as an alternative material system to the standard electrodes of copper and graphite used in electrical discharged machining ...
-
(2014-10-01)Various proposed metallic nuclear fuel designs for fast reactors may require powder fabrication methods and the reactive nature of uranium metal creates unique challenges. Spherical powder is desired in some fuel concepts ...
-
(1979)Water and sediment samples taken from an area near the discharge of the Galveston Sewage Treatment Plant were analyzed for copper, nickel, lead and zinc. Two twenty-four hour sampling periods were conducted at four hour ...

Little and Large Herbivores as Indicators of Trophic Transfer: Do Trace Nutrients Drive Populations? (2019-10-07)Trace minerals, such as copper, iron, and zinc, are essential for reproduction, growth, and immunity of mammalian herbivores and the growth of their populations. I examined the relationship between supplies of essential ...

(Texas A&M University, 2006-10-30)The primary objectives of this study were: (1) to verify the effectiveness of ECAE to induce equal amounts of strain and grain refinement in bars of different cross-sectional areas, (2) to determine the effectiveness of ...
-
(2009-05-15)The plasma-based etching processes of copper (Cu) and titanium tungsten (TiW) thin films, and the electromigration of the copper lines patterned by above etching processes were studied. Instead of vaporizing the plasma/copper ...

(1988)This paper examines the reaction pathway in which Fe²⁺ displaces the Cu²⁺ of Cu²⁺-ovotransferrin-CO₃²⁻ to yield Fe³⁺-ovotransferrin-CO₃²⁻. Electron paramagnetic was used jointly with stopped flow and regular spectroscopy ...
-
(1978)The equilibria involving gaseous species above the condensed Cu-Sn system have been experimentally investigated at elevated temperatures by the high temperature mass spectrometric technique. The molecules Cu₂, CuSn, Sn₂, ...
-
(1979)Overt poisoning by some trace elements (Cu, Hg, Mn, Pb) is known to cause extensive central nervous system damage which can result in mental retardation. Recent evidence indicates that low, undetectable exposure to lead ...
