The sensor is made from nano-patterned polycrystalline CuO NWs, which are highly sensitive ... the Cu NWs are converted into copper oxide. During this process, copper atoms diffuse outward to ...

An international group of scientists proposed to use copper oxide (CuO) and iron oxide (Fe2O3) nanofluids to cool down the operating temperatures of photovoltaic-thermal (PVT) systems.

Using a combination of experiments and computer simulations, scientists now understand how oxygen affects the way the catalyst copper oxide (CuO) reacts with hydrogen (H 2) versus carbon monoxide ...

Reduction is the gain of electrons by a substance. It is also the loss of oxygen from a substance. For example, copper(II) oxide can be reduced to form copper when it reacts with hydrogen: ...
