Molecular basis for antioxidant enzymes in mediating copper detoxification in the nematode Caenorhabditis elegans.

PLoS ONE, 2014
Antioxidant enzymes play a major role in defending against oxidative damage by copper. However, few studies have been performed to determine which antioxidant enzymes respond to and are necessary for copper detoxification. In this study, we examined both

Electrostatic‐Attraction‐Driven Self‐Assembled Graphene‐Disordered Rocksalt Composite Cathode for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A non‐aqueous, solution‐based graphene‐wrapping strategy is shown to stabilize disordered rocksalt LMTOF cathodes without structural degradation. The graphene‐wrapped cathode suppresses oxygen loss and parasitic interfacial reactions, lowers impedance growth, and delivers improved cycling stability and rate capability compared with conventional ball ...

Mimicking Silent Synapse Recruitment: A SiOx/Cu‐Pancake Memristive Device For Analog Neuromorphic Computing

Advanced Functional Materials, EarlyView.
Electroforming‐free TiN/SiOx/Cu/SiOx/TiN memristive devices exploit pancake‐like Cu nanoparticles embedded in a SiOx double layer to create a heterogeneous Schottky‐barrier landscape. Under bias, oxygen‐vacancy redistribution progressively lowers local barriers and recruits initially inactive Cu‐PC pathways into a parallel conduction ensemble, enabling

Influence of Age and Production Type on Liver Copper Concentrations in Calves [PDF]

, 2004
A retrospective study of necropsy reports was undertaken to assess the relation between liver copper concentration and age, sex, and production class for calves that did not have a history compatible with copper toxicosis or with copper deficiency ...
