Removing tritium produced by D-D fusion and recycling part of it after it decays to He-3 significantly reduces the fraction of fusion energy carried by neutrons in a D-D system. For a catalyzed D-D system (no tritium removal), the peak dpa rate in candidate structural materials is 25-35% lower than that in an equivalent D-T system with the same fusion power wall loading. The gas production and ...

Presently in India, about 960 million tonnes of solid waste is being generated annually as by-products during industrial, mining, municipal, agricultural and other processes. Of this 350 million tonnes are organic wastes from agricultural sources; 290 million tonnes are inorganic waste of industrial and mining sectors and 4.5 million tonnes are hazardous in nature. Advances in solid waste manag...

Abstract To date, the highest certified efficiency has reached 25.7% for laboratory‐scale perovskite solar cells (PSCs). Breakthroughs in commercialization of PSCs is achieved continuously. Therefore, recovery decommissioned devices that are closely related to extremely urgent. More importantly, lead (Pb) and other materials ecotoxic biotoxic. Due improper disposal devices, serious heavy metal ...
