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 ...

Copper and Copper Proteins in Parkinson’s Disease [PDF]
Oxidative Medicine and Cellular Longevity, 2014 Copper is a transition metal that has been linked to pathological and beneficial effects in neurodegenerative diseases. In Parkinson’s disease, free copper is related to increased oxidative stress, alpha-synuclein oligomerization, and Lewy body formation. Decreased copper along with increased iron has been found insubstantia nigraand caudate nucleus of
