TL;DR: In this paper, a general approach to a series of monodispersed atomic transition metals (for example, Fe, Co, Ni) embedded in nitrogen-doped graphene with a common MN4C4 moiety, identified by systematic X-ray absorption fine structure analyses and direct transmission electron microscopy imaging, was reported.

TL;DR: A general approach to preparing highly uniform, solution-processable, phase-pure semiconducting nanosheets is reported, which involves the electrochemical intercalation of quaternary ammonium molecules into 2D crystals, followed by a mild sonication and exfoliation process.

TL;DR: In this article, a single-atom tailoring strategy was proposed to boost the activity of Pt nanocatalysts with minimal loss in surface active sites, and the single-nickel-atom-modified Pt nanowires with an optimum combination of specific activity and ECSA for the hydrogen evolution, methanol oxidation and ethanol oxidation reactions.

TL;DR: In this article, the fundamental kinetics of the electrocatalytic sulfur reduction reaction (SRR), a complex 16-electron conversion process in lithium-sulfur batteries, is investigated.

TL;DR: This study designed and synthesized hyperbolic architectured ceramic aerogels with nanolayered double-pane walls with a negative Poisson’s ratio and a negative linear thermal expansion coefficient that display robust mechanical and thermal stability and are ideal for thermal superinsulation under extreme conditions, such as those encountered by spacecraft.
