The discharge of heavy metals into aquatic ecosystems has become a matter of concern in India over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. Industrialization in India gained a momentum with initiation of five year developmental plan in the early 50's. The pollutants of concern include lead, chromiu...

In this paper the use of laser-induced plasma spectrometry has been shown to occur in reduced-pressure laser-induced plasmas from brass (Cu–Zn) samples, the vapour pressures of (LIPS) for the quantitative analysis of Al, Cu, Fe, Pb and Sn components in solid zinc alloys is evaluated. Laser-induced Cu and Zn being di erent by several orders of magnitude.6 As a result, when using internal standar...

Oxygen Electrocatalysis In article number 2202215, Xuerong Zheng, Xiaopeng Han, and co-workers report a class of Janus homologous heterostructures (metal alloys/sulfides) via an ultrafast high-temperature shock strategy. Benefiting from the synergistic effect metallic sites in interfaces, exhibit enhanced oxygen catalytic performance impressive durability as efficient air cathode electrocatalys...

To reduce greenhouse gas emissions and fuel consumption, it is important to utilize lighter materials in vehicles. Magnesium the lightest structural metal, but corrosion resistance of magnesium alloys limited. The powder thermal diffusion alloying method can enhance surface by fabricating a metallic coating. huge consumption powders potential environmental pollution problems should be controlle...
