Application

Copper (granular) can be used as a catalyst in the hydrogenation of ethylene. It can be impregnated on activated carbon material and used as an adsorbent and also as a catalyst for the removal of SO2 from flue gases.

To assess whether serum copper in Alzheimer disease (AD) correlates with cognitive scores, beta-amyloid, and other CSF markers of neurodegeneration. The authors studied copper, ceruloplasmin, total peroxide, and antioxidants levels (TRAP) in serum; beta-amyloid in plasma; and copper, beta-amyloid, h-tau...

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper modulate tumor growth. Chronic exposure...

Carbon monoxide (CO) produced in many large-scale industrial oxidation processes is difficult to separate from nitrogen (N2), and afterward, CO is further oxidized to carbon dioxide. Here, we report a soft nanoporous crystalline material that selectively adsorbs CO with adaptable...
