The design of nanocomposites as a light-capturing system applied in photocatalytic water splitting is an emerging area research. In our study, simple situ photodeposition method was proposed for the synthesis CdS nanoflowers modified by nickel-based bifunctional, i.e., Ni/Ni(OH)2, cocatalysts. introduction cocatalysts has demonstrated notable enhancement hydrogen evolution efficiency CdS. quantity supported on played important role governing light absorption capability and efficacy....
Saturn-like (SL) N-doped VS2 as a cathode material for aqueous zinc-ion batteries (ZIBs) is synthesized into hollow mesoporous carbon spheres via confinement growth strategy. SL VS2@CS shows novel three-step deintercalation process at wide voltage range (0–1 V), which efficiently enhances the Zn2+ storage capacity. In addition, confined effect of can emphatically inhibit pulverization and volume induced by massive insertion, finite element simulation confirms that structure alleviate stress...
We investigate the Cooper pair splitting based on crossed Andreev reflection in a two-dimensional narrow superconductor coupled to two leads, where leads are van der Waals (vdW) spin valves formed by inserting bilayer graphene (BLG) between antiparallel insulating ferromagnetic layers. In this BLG-based $n$-type vdW valve/superconductor/$p$-type valve junction with edge-contact geometry, when controlling Fermi energy and interlayer electric field BLG independently top- bottom-gate voltages...
The catalytic activity of single-layer ZnGeN<sub>2</sub> is better and the band edge positions can be effectively tuned to match with redox potentials water by biaxial strain.
Abstract The structural, dynamical, and thermodynamics properties of InX (X = P, As, Sb) with zinc‐blende structure are investigated by performing first‐principles calculations within the local density approximation (LDA). phonon‐dispersion curves along several high‐symmetry lines at Brillouin zone together corresponding phonon states determined using density‐functional perturbation theory (DFPT). It is found that lattice constants frequencies Γ , X points were in very good agreement other...
Using the density functional theory, we investigate electronic properties of ZnO nanowires (NWs) and faceted nanotubes (NTs) under a transverse electric field. We find that band gap nanostructures tends to decrease as field is increased, variation dependent upon diameter wall thickness. Furthermore, applied could induce semiconductor-metal transition enhance electron effective mass. These results provide valuable guide for future application in microelectronic optoelectronic materials nanodevices.
The effects of the electric field on radial deformation and electronic properties armchair zigzag single-walled ZnO nanotubes are investigated by density functional theory. Under transverse field, circular cross-sections deformed to elliptic. In addition, bandgap nanotube gradually reduced with increasing strength. Such field-induced modulation effect is enhanced in larger tube diameter, but not sensitive chirality. mechanisms variations bandgaps analyzed.

The adsorption of carbon on Ni (111) surface is studied with density functional theory in this paper. energy and states calculated. We analyzed the diamond adsorbed Ni(111) surface, result shows that they have similar electronic structure, namely, both nonbonding bonding sp3 hybridized electrons. Furthermore, it found atoms those are prone to form a diamond-like structure.
