Copper induces cell death by targeting lipoylated TCA cycle proteins
Science, 2022 Copper is an essential cofactor for all organisms, and yet it becomes toxic if concentrations exceed a threshold maintained by evolutionarily conserved homeostatic mechanisms. How excess copper induces cell death, however, is unknown.

Design and material based Sustainable Mobility – Copper vs. REE [PDF]
E3S Web of Conferences, 2022 Carbon neutrality by 2050 is one of the greatest challenges of our society. Hence, the electrification of the mobility sector belongs to those to focus on, due to their high carbon intensity, when based on combustion engines.

Color of Copper/Copper Oxide [PDF]
Advanced Materials, 2021 AbstractStochastic inhomogeneous oxidation is an inherent characteristic of copper (Cu), often hindering color tuning and bandgap engineering of oxides. Coherent control of the interface between metal and metal oxide remains unresolved. Coherent propagation of an oxidation front in single‐crystal Cu thin film is demonstrated to achieve a full‐color ...

The Behaviour of Low Arsenic Copper Anodes at High Current Density in Electrorefining [PDF]
Archives of Metallurgy and Materials, 2023 Arsenic is the only beneficial impurity for copper electrorefining through inhibiting anode passivation and the formation of floating slimes. The behaviour of copper anodes with different content of arsenic were studied at high current density (>280 A/m ...

Copper-dependent autophagic degradation of GPX4 drives ferroptosis
Autophagy, 2023 Ferroptosis is a type of iron-dependent regulated cell death characterized by unrestricted lipid peroxidation and membrane damage. Although GPX4 (glutathione peroxidase 4) plays a master role in blocking ferroptosis by eliminating phospholipid ...
