TL;DR: In this article, a few-layered WS2 is synthesized by chemical vapor deposition on quartz, which is successfully used as light sensors and the results indicate that the electrical response strongly depends on the photon energy from the excitation lasers.

TL;DR: The findings indicate that liquid phase exfoliation methods can be used to produce large quantities of electrochemically active, two-dimensional layers of MoS2 and can act as an ideal material in several applications related to electrochemistry.

TL;DR: In this paper, the performance of supercapacitor devices fabricated using 1-pyrenecarboxylic acid (PCA)-functionalized graphene electrodes was investigated and the specific capacitances obtained (using 6 M KOH aqueous solution as an electrolyte) were found to be an order of magnitude higher than nonfunctionalized GAs.

TL;DR: This work experimentally determined the adsorption energy of oxygen molecules on graphene and 2D tungsten disulfide using temperature-programmed terahertz (THz) emission microscopy (TPTEM) and introduced TPTEM as a novel and powerful tool for molecular surface science.

TL;DR: The nature of variation of photocurrent with temperature confirms that the trap states are continuously distributed within the mobility gap in these thin film of MoS2, and play a vital role in influencing the overall photo response.
