TL;DR: A comprehensive joint experiment–theory investigation of point defects in monolayer molybdenum disulphide prepared by mechanical exfoliation, physical and chemical vapour deposition and influence of defects on electronic structure and charge-carrier mobility is predicted by calculation and observed by electric transport measurement.

TL;DR: A suite of methods to acquire atomic-resolution TEM images of several metal organic frameworks that are generally recognized as highly sensitive to electron beams and identify individual metal atomic columns, various types of surface termination, and benzene rings in the organic linkers are developed.

TL;DR: An atomic resolution study of the structure and composition of the grain boundaries in polycrystalline Sr0.6K 0.4Fe2As2 superconductor was performed in this paper, showing that a large fraction of grain boundaries contain amorphous layers larger than the coherence length.

TL;DR: In this paper, the authors provide insight into the mechanisms that govern highly reproducible controlled resistive switching via a nanofilament by using an asymmetric metal-insulator-semiconductor structure.

TL;DR: The translocation of spherelike con.A and the prolate bovine serum albumin under an electric field by a solid-state nanopore is investigated and could be characterized and differentiated due to their intrinsic shape difference by analyzing the ionic current.
