Click reactions have become very common and powerful ligation techniques, of which 1,3-dipolar cycloadditions have most frequently been employed. Since metal-mediated cycloadditions are incompatible in biomedical applications ...

The charge-transfer interaction of different nucleobases with Cu2+has been investigated by means of ESR and optical absorption studies. It could be shown that cytosine forms the strongest complex. The greatest reduction ...

One of today's megatrends in the industrial environment is additive manufacturing. Faster prototyping, customized products like hearing devices, integrated functions like heatsinks and many other opportunities are offered ...

To understand the mobility of heavy metals during oxidative weathering of sulfides, we investigated weathering processes of tetrahedrite [(Cu,Fe,Zn,Hg)12(Sb,As)4S13] in an oxidation zone with abundant siderite (FeCO3) and ...

Background: The oxidative modification of LDL is believed to be an initial step in atherosclerosis. Thus, antioxidative substances such as carotenoids may have a role in the prevention of coronary heart disease. We examined ...

In Escherichia coli, cytoplasmic copper ions are toxic to cells even at the lowest concentrations. As a defense strategy, the cuprous oxidase CueO is secreted into the periplasm to oxidize the more membrane-permeable and ...
