TL;DR: It has been established that a postannealing of N-graphene after gold intercalation causes a conversion of the N environment from pyridinic to graphitic, allowing to obtain more than 80% of all embedded nitrogen in graphitic form, which is essential for the electron doping in graphene.

TL;DR: It is shown by angle-resolved photoemission spectroscopy that a tunable gap in quasi-free-standing monolayer graphene on Au can be induced by hydrogenation, and thereby provides a model system to study hydrogen storage in carbon materials.

TL;DR: In this article, a composite MoS2/carbon nanotubes (CNT) material has been produced by hydrothermal decomposition of a mixture of multiwall CNTs and a water solution of ammonium molybdate and thiourea and X-ray photoelectron spectroscopy revealed a downshift of C 1s peak of the composite as compared to the pristine CNT sample that was related to charge transfer between the components.

TL;DR: The discovery of 505–million-year-old chitin is presented, found in exceptionally well preserved Vauxia gracilenta sponges from the Middle Cambrian Burgess Shale, indicating that, given the right fossilization conditions, chit in is stable for much longer than previously suspected.

TL;DR: In this article, a modified B layer of the Fe3O4100 surface is explained based on density functional theory DFT and ab initio atomistic calculations as a laterally distorted surface layer containing octahedral iron and oxygen.
