Synthesis of Ultrathin FeS Nanosheets via Chemical Vapor Deposition.

Fe-based 2D materials exhibit rich chemical compositions and structures, which may imply many unique physical properties and promising applications. However, achieving controllable preparation of ultrathin non-layered FeS crystal on SiO/Si substrate remains a challenge. Herein, the influence of temperature and molecular sieves is reported on the synthesis of ultrathin FeS nanosheets with a thickness as low as 2.

Band Gaps and Optical Properties of NiO upon Strain: Combining First-Principles Calculations and Machine Learning.

Rare earth nickel-based perovskite oxides (NiO) have been widely studied over recent decades because of their unique properties. In the synthesis of NiO thin films, a lattice mismatch frequently exists between the substrates and the thin films, which may affect the optical properties of NiO. In this paper, the first-principles calculations were employed to study the electronic and optical properties of NiO under strain.

Glial cell adhesive molecule unzipped mediates axon guidance in Drosophila.

Axon guidance needs help from the glial cell system during embryogenesis. In the Drosophila embryonic central nervous system (CNS), longitudinal glia (LG) have been implicated in axon guidance but the mechanism remains unclear. We identified the protein encoded by the Drosophila gene unzipped (uzip) as a novel cell adhesion molecule (CAM).
