TL;DR: This work intentionally creates atomic-scale defects in the hexagonal lattice of pristine WS2 and MoS2 monolayers using plasma treatments and studies the evolution of their Raman and photoluminescence spectra to determine the defectiveness of 2D semiconducting nanosheets.

TL;DR: It is reported that, contrary to current understanding, chemical vapor deposited transition metal dichalcogenide monolayers exhibit poor long-term stability in air, and a potential solution is demonstrated featuring encapsulation of the monolayer sheet by a 10-20 nm thick optically transparent polymer (parylene C).

TL;DR: Theoretical and experimental studies together show phosphorene as a highly potent polysulfide immobilizer for lithium-sulfur batteries enabling a high capacity, good rate capability, and excellent cycling stability.

TL;DR: The adsorption of red phosphorus into porous carbon provides a composite anode material for lithium-ion batteries that shows highly reversible lithium storage with high coulombic efficiencies and stable cycling capacity.

TL;DR: It is shown that with the right precursors and appropriate tuning of the CVD growth conditions, ReS2 nanosheets can be made to orient perpendicular to the growth substrate and significantly improve their performance as polysulfide immobilizers and electrochemical catalysts in lithium-sulfur (Li-S) batteries and in hydrogen evolution reactions (HER).
