Ultrathin MoS2-MoO3-x heterojunction nanosheets with unique features were introduced as biocompatible, non-cytotoxic, and visible light-sensitive stimulator layers for the controlled differentiation of human neural progenitor cells (hNPCs) into nervous lineages. hNPC was also investigated on reduced graphene oxide (rGO)-containing scaffolds, that is, rGO rGO/MoS2-MoO3-x nanosheets.

Two-dimensional (2D) magnetic materials are the key to development of new generation in spintronics technology and engineering multifunctional devices. Herein, electronic, spin-resolved transmission, gas sensing properties 2D g-C4N3/MoS2 van der Waals (vdW) heterostructure have been investigated by using density functional theory with non-equilibrium Green's function method. First, vdW demonstrates ferromagnetic half-metallicity superior adsorption capacity for molecules. The spin-dependent electronic transport g-C4N3/MoS2-based nanodevice is obviously regulated parallel or anti-parallel spin configuration electrodes, leading perfect single-spin conduction behavior a nearly 100% filtering efficiency, negative differential resistance effect, other interesting electrical phenomena. Moreover, exhibits directional dependency strong anisotropic under bias windows, indicating that electric current propagates more easily through vertical direction than horizontal direction. physical mechanisms revealed analyzed presenting bias-dependent transmission spectra combination projected local device states. Finally, sensor sensitive CO, NO, NO2, NH3 molecules chemisorption type. chemical leads formation electrons on scattering center ultimately affects properties, resulting maximum sensitivity reaching 6.45 NO at 0.8 V.

Dissolved gas detection is very important for an oil-immersed transformer fault. We examined the adsorption characteristics and sensitivity processes of monolayer NbSe2 doped with Ag, Pd, Pt on five typical gases (H2, CO, CO2, CH4, C2H2) in using first-principles calculations. While Pd–NbSe2 system only has great desorption properties H2 at high temperature, Ag/Pt–NbSe2 outstanding possessions ambient temperature. Therefore, micro-nanomaterials prepared by Ag/Pd/Pt–NbSe2 are expected to be used as sensors detecting H2. The systems can C2H2 temperature temperatures, but effect not excellent. Micro-nanomaterials Pd/Pt–NbSe2 have excellent performance CH4 CO2 candidates sensors. This paper systematically studies potential application a metal-doped oil dissolution provides theoretical guidance detection. It theoretically proven that scheme dissolved oil.
