New findings reveal that organosulfate groups, not carboxyls, control graphene oxide's surface charge in water, challenging long-standing models and reshaping its chemical profile. (Nanowerk Spotlight ...
Researchers at the National University of Singapore (NUS) have observed a doping-tunable charge density wave (CDW) in a single-layer semiconductor, Chromium(III) selenide (Cr 2 Se 3), extending the ...
