    Monolayer WxMo1−xS2-based field effect transistors are demonstrated for the first time on the monolayer WxMo1−xS2 flake, which is grown by the chemical vapor deposition method under an atmospheric pressure. Carrier transport study on the fabricated WxMo1−xS2 FETs has been analyzed using temperature-dependent current measurement, and a field effect mobility of ≈30 cm2 V−1 s−1 at 300 K is obtained.

  2. Near-Stoichiometric Bulk Graphane from Halogenated Graphenes (X = Cl/Br/I) by the Birch Reduction for High Density Energy Storage

    Bulk graphane is prepared from halogenated graphene precursors (X = Cl/Br/I), giving levels of stored hydrogen in the material close to the theoretical limit. The graphane produced is stable in air and hydrogen can be subsequently desorbed at elevated temperature. High density hydrogen storage makes graphane a possible option for future hydrogen-powered devices.

    Near-infrared laser-triggered nitric oxide (NO) nanogenerators are prepared by combining photothermal agents with heat-sensitive NO donors. NO release is realized via the conversion of light to heat, and excellent controllability is achieved in aqueous solution and multidrug-resistant (MDR) cancer cells under near-infrared laser irradiation. Furthermore, the proposed NO-releasing platform can successfully induce multidrug-resistance reversal and tumor inhibition in a humanized MDR cancer model.

  4. Biocompatible D–A Semiconducting Polymer Nanoparticle with Light-Harvesting Unit for Highly Effective Photoacoustic Imaging Guided Photothermal Therapy

    A water-dispersible and biocompatible D–A semiconducting polymer nanoparticle (PPor-PEG NP) with light-harvesting unit is successfully developed for highly effective photoacoustic imaging guided photothermal therapy. The photothermal conversion efficiency of the PPor-PEG NPs is determined to be as high as 62.3% for achieving 100% tumor elimination.

  5. A Lyotropic Liquid-Crystal-Based Assembly Avenue toward Highly Oriented Vanadium Pentoxide/Graphene Films for Flexible Energy Storage

    A novel lyotropic liquid-crystal-based assembly strategy is developed for the first time to fabricate composite films of vanadium pentoxide nanobelts and graphene oxide sheets with highly oriented layered structures. The resulting films manifest high electrical conductivity, good mechanical stability, and excellent flexibility, which allow them to be utilized as high performance electrodes in flexible energy storage devices.
