Summary: In this study, a facile approach for controlled one step Rhenium doping in multilayer Molybdenum Disulphide (MoS2) was developed. The morphology of MoS2 was found to be dependent on the dopant concentrations, with a flower-like morphology observed at higher doping concentrations. A clear correlation between the shift in PL and Raman peaks as a function of Re doping concentrations was demonstrated, indicating potential applications of controllably doped thin layers of MoS2 in unexplored areas.

Summary: The control of crystal polymorphism and exploration of metastable, two-dimensional, 1T' phase, transition-metal dichalcogenides (TMDs) have been the focus of research due to their potential applications in various fields. However, the high energy difference and phase change barrier between 1T' and 2H phases make it difficult to obtain monolayer 1T' phase TMDs. In this study, we successfully grew 1T' phase WS2 atomic layers using chemical vapor deposition (CVD) with alkali metal assistance. The resulting high-quality crystals showed superconductivity and hold promise for applications such as quantum computing and energy storage devices. The alkali metal assisted gas-source CVD growth method provides a viable approach to realizing large-scale, high-quality TMD atomic layers.

Summary: Hydrogen production through water splitting is a promising alternative to traditional fossil fuels, but the high cost of precious metal catalysts is a challenge. Two-dimensional transition metal dichalcogenides (TMDs) have attracted attention as non-precious metal catalysts, but their poor electron conductivity and limited active sites restrict their catalytic performance. This study demonstrates the direct growth of TMDs on a conductive carbon paper substrate, improving their catalytic activity for water splitting.

Summary: Engineering interfacial interactions is crucial for manipulating the properties and applications of two-dimensional (2D) materials. In this study, a self-relaxation vapor-liquid-solid (SRVLS) growth method for 2D transition metal dichalcogenides (TMDs) was proposed and investigated. The growth process involves coordination between the precipitation of metal oxides and the capture of chalcogens, resulting in loose interface adhesion and strain relaxation in the as-grown TMD layers. The SRVLS-grown TMDs exhibit significantly reduced adhesion energy compared to traditional vapor-solid (VS) growth, and the growth features allow for curl-free delamination and reverse transfer of TMD layers onto target substrates through water-dissolving the solidified droplets.

Summary: The interaction between molybdenum disulfide (MoS2) and light is investigated in this study, with the aim of constructing highly integrated optoelectronics in communication and wearable healthcare. The researchers fabricate a MoS2-based phototransistor using polyvinylidene fluoride and 1-ethyl-3-methyl-imidazolium bis(trifluoromethylsulfonyeimide) ion-gel as a replacement for oxide. They find that the photoelectrical effect of the phototransistor can be greatly tuned by the gate voltage, resulting in a large tunability of carrier concentration. By tuning the carrier concentration, the photoresponse can be extended from the visible region to the short infrared region.

Summary: This article introduces a self-powered near-infrared detector that can work without an external power source, which has important applications in various fields. A self-powered near-infrared detector with a metal-semiconductor-metal structure was fabricated by attaching a hydrothermal synthesized Te microwire to Ti electrodes. Under 1550 nm illumination, the detector exhibits a responsivity of 3.47 x 10(5) V/W and 170 mA/W and a detectivity of 4 x 10(9) Jones at room temperature. The competitive performance is attributed to the asymmetric Schottky barrier-induced built-in electric fields. The highly anisotropic structure of the Te microwire allows the device to achieve a polarization dichroic ratio of up to 2.1 under 1550 nm irradiation. This work provides a simple strategy for realizing polarization-sensitive self-powered near-infrared detection in a wide temperature range.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
