Copper (Cu) is a transition element, belonging to Group 11 (formerly Group IA) of the Periodic Table. It is an important non-ferrous metal and a micronutrient with two distinct functions - to serve as a plant nutrient by being an activator or by being a part of certain enzymes like tyro...
It’s well known that copper, as one essential trace element, plays an important role in many life processes [40]. However, the disorder of copper ion may cause high cytotoxicity to human beings and lead to some neurodegenerative diseases such as Alzheimer’s and Wilson’s disease [41]. Th...
Copper is an essential trace element for living organisms with many key roles in several metabolic pathways, including respiration, iron metabolism, antioxidant activity, tissue integrity and synaptic function. Cu can exist in two oxidation states Cu+ and Cu2+ in biological systems as it is charact...
The results of this study show that, whilst CuSCN has proved to be an excellent hole-extraction layer for high performance lead-perovskite and organic photovoltaics, it is unsuitable as a hole-transport layer in inverted B-γ-CsSnI3 perovskite photovoltaics processed from solution....

As an essential micronutrient, copper is required for a wide range of physiological processes in virtually all cell types. Because the accumulation of intracellular copper can induce oxidative stress and perturbing cellular function, copper homeostasis is tightly regulated. Recent studies identified a nov...
As outlined above, intracellular copper exists in an immense variety of static forms that involve a multiple oxidation states with favoured ligand speciations (seebelow) or mixed-valent copper complexes. However, it also can change by reacting with “self” (seeEq. 1.) within sub-nanometer dist...
Copper definition: a malleable, ductile, metallic element having a characteristic reddish-brown color: used in large quantities as an electrical conductor and in the manufacture of alloys, as brass and bronze. Symbol: Cu; atomic weight: 63.54; atomic num
Copper is an essential trace element required in various physiological processes in the human body. 2. Dysregulation of copper homeostasis and copper-induced cell death (cuproptosis) are acknowledged as potential contributors to the pathogenesis of atherosclerosis. ...
