Matter is the physical substance that makes up the universe and is characterized by being made of particles that possess mass. The state of matter refers to the density of the particles and how that affects their properties, typically resulting in matter being a solid, liquid, or gas. ...
The triplet excited state of natural organic matter (~(3)NOM*) is an important reactive intermediate in sensitizing transformation of a wide range of environmentally relevant organic compounds, but the impact of trace metals on the fate and reactivity of ~(3)NOM* is poorly understood. In this...
Copper is found at a concentration of 50 ppm in the earth’s crust, and its concentration in seawater is 0.001–0.02 ppm. Although copper can also be obtained in an almost pure state in nature, about 85% of the copper mined today is derived from low-grade ores containing 2% or less ...
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...
Since the discovery of high temperature copper oxide superconductors nearly thirty years ago, much has been learned about the nature of the superconducting state and the novel forms of quantum matter involved. This Review concentrates on the related issues that have not been resolved, notably the co...

The compression of solids by a ramped pressure pulse, as opposed to shock compression, affords the potential to create states of solid-state matter at pressures greater than those achievable in diamond anvil cells. A fundamental understanding of this process requires a knowledge of the loading condi...
Chilean state-owned copper producer Codelco has made a premium offer of $89/mt to its major Chinese clients for copper cathode supply in 2024, sources familiar with the matter said Nov. 8. The premium, which is charged on the top of the London Metal Exchange copper price, is down 36.4%...
The respective Zn···Zn distance and ZnOZn angle in the dimeric unit of 4 -dimer are 4.025(3) and 148.1(2)°. The 3 -dimer displays axial X-band electron paramagnetic resonance spectral features ( E s = 0) in the powder state at 4 K, giving g ∥ = 2.51 ( A ∥ ,s = (9.6...
