TL;DR: Strongly fluorescent graphene quantum dots have been prepared by one-step solvothermal method with PL quantum yield as high as 11.4%.

TL;DR: In this article, the intrinsic state emission plays a leading role, as opposed to defect state emission in GQDs, and the luminescence mechanism (the competition between both the defect state emissions and intrinsic state emissions) is explored in detail.

TL;DR: It is proved that the chemical modification using N or O dopant significantly enhances the interaction between the carbon hosts and the polysulfide guests via dipole-dipole electrostatic interaction and thereby effectively prevents shuttle ofpolysulfides, allowing high capacity and high coulombic efficiency of Li-S batteries.

TL;DR: In this article, the synthesis and electrocatalytic properties of ruthenium cobalt phosphide hybrid clusters for the hydrogen evolution reaction (HER) were investigated, and two types of catalysts are investigated: wet chemical reduction of Ru3+ on pre-formed cobalt-phosphide (CoP) nanoparticles results in Ru/CoP side-by-side structures (Ru/CP); while phosphorizing chemically reduced RuCo alloy leads to the formation of hybrid ruthensium cobALT phosphide (RuCoP), which shows significantly

TL;DR: In this article, a large number of DFT calculations regarding the chemistry of oxide surfaces are examined and their qualitative conclusions can be predicted by using a few rules derived from the Lewis acid-base properties of the species involved.
