Chong Ka Shing1, Tam Teck Lip Dexter2 1Student, River Valley High School 2Institute of Materials Research and Engineering, A*STAR ABSTRACT Recent studies have proven that several Cu2-xS compounds display satisfactory figure of merit (ZT values, which evaluate the conversion efficiency of a thermoelectric material. In this study, sulfur rich Cu2-xS nanocrystals were synthesised with dithiooxamide …
Aaron Sarkar ABSTRACT Chemical contamination of drinking water is a major global health issue. While modern water filters treat some major contaminants, not all impurities can be filtered. Moreover, all filters are not cost-efficient and environmentally friendly. The current study aims to explore the effectiveness and efficiency of reduced graphene-oxide-coated sand as a water filter. …
