TL;DR: This work reports a high-yield exfoliation process using lithium, potassium and sodium naphthalenide where an intermediate ternary Li(x)MX(n) crystalline phase (X=selenium, sulphur, and so on) is produced.

TL;DR: The preparation of a 2D conjugated aromatic polymer synthesized via C-C coupling reactions between tetrabromopolyaromatic monomers is reported, which allows a fast charge/discharge of sodium ions, with impressive reversible capacity, rate capability and stability metrics.

TL;DR: Transmission electron microscopy studies reveal that the interconnected MoS2 nanocrystals created during the phase change process are reformable even after multiple cycles of galvanostatic charging/discharging, which allows them to play important roles in the long term cycling performance of the chemically intercalated TMD materials.

TL;DR: By hydrogenating the intercalated Li to form lithium hydride (LiH), unprecedented long-term air stability of the 1T' phase can be achieved and this passivation method has wide applicability for other alkali metals and TMDs.

TL;DR: High-quality large-sized hexagoal WSe2 crystals can be grown on dielectric substrates using atmospheric chemical vapor deposition in the presence of hydrogen gas and have a photoresponsivity comparable to that of exfoliated flakes.
