2D layered molybdenum disulfide (MoS) has garnered considerable attention as an attractive electrode material in sodium-ion batteries (SIBs), but sluggish mass transfer kinetic and capacity fading make it suffer from inferior cycle capability. Herein, hierarchical MoS nanosheets decorated porous TiO nanofibers (MoS NSs@TiO NFs) with rich oxygen vacancies are engineered by microemulsion electrospinning method and subsequent hydrothermal/heat treatment. The MoS NSs@TiO NFs improves ion/electron transport kinetic and long-term cycling performance through distinctive porous structure and heterogeneous component. Consequently, the electrode exhibits excellent long-term Na storage capacity (298.4 mAh g at 5 A g over 1100 cycles and 235.6 mAh g at 10 A g over 7200 cycles). Employing NaV(PO) as cathode, the full cell maintains a desirable capacity of 269.6 mAh g over 700 cycles at 1.0 A g. The stepwise intercalation-conversion and insertion/extraction endows outstanding Na storage performance, which yields valuable insight into the advancement of fast-charging and long-cycle life SIBs anode materials.

Two-dimensional (2D) materials have been identified as promising candidates for future electronic devices. However, high dielectric constant (κ) materials, which can be integrated with 2D semiconductors, are still rare. Here, we report a hydrate-assisted thinning chemical vapor deposition (CVD) technique to grow manganese oxide (MnO) single crystal nanosheets, enabled by a strategy to minimize the substrate lattice mismatch and control the growth kinetics.

Edge contact is essential for achieving the ultimate device pitch scaling of stacked nanosheet transistors with monolayer 2-dimensional (2D) channels. However, due to large edge-contact resistance between 2D channels and contact metal, there is currently a lack of high-performance edge-contact device technology for 2D material channels. Here, we report high-performance edge-contact monolayer molybdenum disulfide (MoS) field-effect transistors (FETs) utilizing well-controlled plasma etching techniques.

A biosensor based on solid-state nanochannels of anodic aluminum oxide (AAO) membrane for both electrochemical and naked-eye detection of microRNA-31 (MiR-31) is proposed. For this purpose, MoS nanosheets, which possess different adsorption capabilities to single-stranded and double-stranded nucleic acids, are deposited onto the top surface of the AAO membrane. Moreover, multi-functional DNA nanostructure have been designed by linking a G-rich sequence for folding to a G-quadruplex at three vertices and a complementary sequence of MiR-31 at the other one vertex of a DNA tetrahedron.

Constructing wide and narrow band gap heterogeneous semiconductors is a method to improve the activity of photocatalysts. In this paper, CMS/ZnO heterojunctions were prepared by solvothermal loading of ZnO particles on the surface of CuMoS nanosheets. The photocatalytic H precipitation rate is about 545 μmol·g·h, which is 6.

Currently, the development of high-performance adsorbents for the removal of nanoplastics in complex aquatic environments is challenging. In this study, a functionalized polyethyleneimine-phosphorylated microcrystalline cellulose/MoS (PEI-PMCC/MoS) hybrid aerogel was prepared and applied to remove carboxyl-modified polystyrene (PS-COOH) nanoplastics from the aqueous solution. Benefiting from the introduced functional groups and the expanded lamellar structure in MoS nanosheets as well as the highly porous 3D structure of the aerogel, PEI-PMCC/MoS demonstrated high efficiency in PS-COOH nanoplastics removal, achieving a 402.
