TL;DR: This work reports on a novel and simple hydrothermal approach for the cutting of GSs into surface-functionalized GQDs, which were found to exhibit bright blue photoluminescence (PL), which has never been observed in GSs and GNRs owing to their large lateral sizes.

TL;DR: In this article, the effect of alloying FA0.85Cs0.15PbI3 with CsPbIsI3 was investigated, and it was shown that the effective tolerance factor can be tuned and the stability of the photoactive α-phase of the mixed solid-state perovskite alloys FA1-xCsxPbisI3 is enhanced.

TL;DR: Graphene applications are just starting, and current investigations are on a number of areas such as composites, nanoelectronics, and transparent electrodes, where a continuous single-layer graphene fi lm could retain high conductivity at very low (atomic) thickness, and avoid contact resistance that occurs in a carbon nanotubes between interconnected nanotube bundles.

TL;DR: A new physical and chemical entrapment strategy is based on a highly efficient sulfur host, namely hollow carbon nanofibers filled with MnO2 nanosheets, which efficiently prevents polysulfide dissolution in Lithium-sulfur batteries.

TL;DR: A new deep learning method that predicts contacts by integrating both evolutionary coupling (EC) and sequence conservation information through an ultra-deep neural network formed by two deep residual neural networks that greatly outperforms existing methods and leads to much more accurate contact-assisted folding.
