Two 28-d experiments were conducted to evaluate the efficacy of low dietary concentrations of Cu as Cu-proteinate compared with 250 ppm Cu as CuSO4 with growth performance, plasma Cu concentrations, and Cu balance of weanling swine as the criteria. In the production study (Exp. 1), 240 crossbred pigs that averaged 19.8 d of age and 6.31 kg BW initially were group-fed (two or three pigs per pen)...

The attractive interactions that exist between d “closedshell” elements of Group 11 have received extensive attention. 2] The term “aurophilicity” has been coined to describe the Au Au bonding interactions that are evident in many molecular and solid-state structures and have been attributed to correlation and relativistic effects. However, relativistic effects cannot be invoked for Cu···Cu int...
The present work highlights recent advances in elucidating the methane oxidation mechanism of inorganic Cu-ZSM-5 biomimic and in identifying the reactive intermediates that are involved. Such molecular understanding is important in view of upgrading abundantly available methane, but also to comprehend the working mechanism of genuine Cu-containing oxidation enzymes.
Juvenile rainbow trout Oncorhynchus mykiss were exposed to diets with low (12.6 nmol g(-1)), normal (50.4 nmol g(-1)) or elevated (4437.5 nmol g(-1)) Cu concentrations in combination with either low (5.8 nmol l(-1)) or normal (48.5 nmol l(-1)) waterborne Cu levels over a 50-day period, during which body mass increased up to fivefold. A nutritional requirement for Cu was demonstrated based on gr...
We demonstrate a template-free synthetic approach for the preparation of a highly conductive Cu/Cu(2)O nanocomposite electrode by a chemical reduction process. Cu(2)O octahedra were prepared through chemical dehydrogenation of as-synthesized Cu(OH)(2) nanowire precursors. To provide a sufficiently electron-conducting network, the Cu(2)O particles were transformed into Cu/Cu(2)O nanocomposites b...
