Copper leaching with aqueous foams for the processing of electronic waste by Régnier, Emilie, Hubau, Agathe, Touzé, Solène, Guignot, Sylvain, Meyer, Daniel, Diat, Olivier, Bourgeois, Damien

“…Copper is almost exclusively leached during this stage, and the complete mass balance in 5 major metals present in WPCBs (aluminum, iron, zinc, nickel and copper) is detailed. Kinetics of the copper leaching were greatly enhanced through addition of substoechiometric quantity of cupric ions at the beginning of the process, so that extensive grinding of the waste is not necessary.…”

Formation mechanism of multiple spallation and its penetration induced by shear localization in NiTi alloy under implosion loading by Xianye Wu, Xiaoyang Pei, Xiang Chen, Hao Zhang, Jin Wang, Xin Yang, Meizhen Xiang, Shang Gao, Fang Wang

“…This study uses nonequilibrium molecular dynamics simulations to explore the dynamic failures and deformation mechanisms of a cylindrical shell composed of nanocrystalline nickel–titanium alloy under implosion loading. We discover that some individual spall planes are sequentially generated in the material along the propagation of a radial stress wave, indicative of the formation of multiple spallation. …”
