We systematically investigate the tunable charge transport in n-channel thin film transistors by n-type doping of graphene electrodes with alkali metal carbonates, which effectively controls the carrier injection from graphene to the channel material, and results in improved electrical characteristics in the devices. Furthermore, the level of contact noise originating from the barrier height fluctuation is analyzed by low-frequency 1/f noise measurements for the first time to understand the tunable charge transport mechanism.

An egg-like Fe3O4@nSiO2-NH2-Fe2O3•xBi2O3@mSiO2 magnetically immobilized nanocatalyst was developed to reduce nitroarenes. The active species, Fe2O3•xBi2O3, was immobilized on the magnetic silica sphere and further encapsulated with a mesoporous silica shell; thus, the catalyst showed such a long lifetime that it maintained its activity for more than 1,500 cycles in a packed-bed continuous microreactor.

We report high-performance field-effect transistors based on solution-derived carbon nanotube films and explore their applications in radio-frequency integrated circuits. The oscillation frequency of the optimized five-stage ring oscillator (RO) based on carbon nanotube film is up to 17.4 MHz. The ROs are used as carrier-wave generators in radio-frequency systems to demonstrate a complete signal transmission process, which suggests that carbon nanotube (CNT) thin-film electronics may soon find their way to radiofrequency applications.

We report a simple electrodeposition method for synthesizing Co3O4 and Co(OH)2 ultrathin nanosheet arrays (UNA) without templates or surfactants; the Co3O4 and Co(OH)2 UNA exhibit high activity for oxygen and hydrogen evolution reactions, respectively, in both alkaline and neutral media.

The biocompatibility of boron nitride (BN) nanosheets was evaluated using osteoblast-like cells (SaOS2). The biocompatibility of BN nanomaterials depends on their size, shape, structure, and surface chemical properties.

Silica materials with one-dimensional pores,ZSM-22,MCM-41, and SBA-15,were chosen to model the inorganic nanopores in shale. Water adsorption does not affect the pore size of ZSM-22 and MCM-41 zeolites,and hence has little influence on the self-diffusivity of methane.However,water reduces the pore size of SBA-15,which retards diffusion of methane.
