Experiments on irradiation of copper alloys Cu-4%Ni and Cu-4%Ni-10%Ga (mass %) by powerful pulsed deuterium plasma (DP) and deuterium ion (ID) flows were carried out in the Plasma Focus (PF) facility. It is noted that the studied ductile copper alloys of the Cu-Ni and Cu-Ni-Ga systems, as well as the previously studied Cu-10% Ga alloy, exhibit a very high crack resistance to the impact of powerful pulsed radiation-thermal loads generated in the PF installation, in comparison with refractory metals - W, Mo, V.

Development of heterojunction materials is an efficient approach for enhancing photocatalytic and photoelectrochemical processes. We develop a ZnO/CuO heterojunction via Cu doping into a ZnO matrix. Structural characterization confirmed that Cu was effectively incorporated into ZnO without any structural changes. The improved optical properties and reduced charge carrier recombination of the doped samples were confirmed ...
