TL;DR: It is shown that by modulating the thicknesses of underlying substrates and capping layers, the interference caused by substrate can significantly enhance the light absorption and emission of WSe2, resulting in a ∼11 times increase in Raman signal and a ∼30 times increased in the photoluminescence intensity of W Se2.

TL;DR: A self-powered and fully integrated smartwatch that consists of flexible photovoltaic cells and rechargeable batteries in the forms of a "watch strap", electrochemical glucose sensors, customized circuits, and display units integrated into a "dial" platform is successfully fabricated for real-time and continuous monitoring of sweat glucose levels.

TL;DR: It is shown that the PL QY of CVD-grown monolayers can be improved from ∼0.1% in the as-grown case to ∼30% after treatment, with enhancement factors ranging from 100 to 1500× depending on the initial monolayer quality.

TL;DR: A transient-mode electroluminescent device based on transition-metal dichalcogenide monolayers is demonstrated to bypass the requirement of ohmic contacts for electrons and holes, and millimetre-scale light emission from a transparent 2D display is observed.

TL;DR: Ni-Mo alloy is demonstrated as an alternative low-cost catalyst with onset potential and saturation current similar to those obtained with platinum, which is a highly promising photocathode for solar hydrogen production.
