Abstract Photoreduction of CO 2 to fuels offers a promising strategy for managing the global carbon balance using renewable solar energy. But decisive process oriented photogenerated electron delivery presents considerable challenge. Here, we report construction intermolecular cascaded π-conjugation channels powering photoreduction by modifying both intramolecular and conjugation conjugated polymers (CPs). This coordination dual is firstly proved theoretical calculations transient...
The performance of donor–acceptor (D–A) conjugated polymer-based photocatalyts for solar hydrogen production is severely limited by poor charge mobility and weak reactive sites. Here, a series D–A polymers with electronegative fluorine atoms on the backbone presented influence fluorination transfer catalytic site activity investigated. Theoretical calculation reveals that sequential A unit benzothiadiazole will activate site, photocatalytic H2 generation process could be illustrated...
Bioabsorbable magnesium alloys are becoming prominent as temporary functional implants, they avoid the risks generated by permanent metallic implants such persistent inflammation and late restenosis. Nevertheless, overfast corrosion of Mg under physiological conditions hinders their wider application medical implant materials. Here we investigate a simple one-step process to introduce cross-linked 3-amino-propyltrimethoxysilane (APTES) silane physical barrier layer on surface Mg-Zn-Y-Nd...
Exploiting an appropriate strategy to prepare fine crystal quality black phosphorus nanosheet (BPNS) catalyst is a major challenge for its practical application in catalysis. Herein, we address this by developing rapid electrochemical expansion scale preparation of BPNSs from bulk phosphorus, which was demonstrated be active cocatalyst photocatalytic nitrogen fixation the presence CdS as photocatalyst. The transient photocurrent and charge density studies show that can efficiently accelerate...
This paper reports that 2D COFs can act as an all-in-one nickel-redox mediated C–O coupling catalyst. Aside from high efficiency and broad substrate compatibility, complete recyclability is another benefit.
Abstract III‐V semiconductor compound crystals are widely used in the advanced infrared detectors and lasers etc. The traveling heater method (THM) vertical Bridgman (VB) two important methods to grow high‐quality, especially low dislocation density bulk single crystals, which furnace temperature gradient G TH , usually plays a key role determining density. This work simulates numerically GaInSb crystal growths with both THM VB, displaying evolutions of field inside crucible domain flow melt...
Bandgap-tunable black phosphorus quantum dots prepared by a liquid exfoliation method in mixture solvent of N-methylpyrrolidone and oleic acid can act as efficient photocatalysts for the degradation rhodamine B. This is first report on solely capable destroying organic pollutants under visible light irradiation.

When pipelines are rapidly filled, dynamic and sometimes dramatic air–water interactions often occur. These interactions, along with their associated pressure temperature oscillations, explored in this paper both experimentally numerically. A computational fluid dynamics (CFD) approach based on a volume of (VOF) formulation is used to simulate the flow field three-dimensions (3D). Thermal conduction convection three different media (air, liquid water, pipe wall) all considered order account...
Phase carried by two orthogonal polarizations can be manipulated independently controlling both the geometric size and orientation of dielectric nanopost. With this characteristic, we demonstrate a novel multifunctional metasurface, which converts part incident linearly polarized light into its cross-polarization encodes phase independently. A beam splitter bifocal metalens were realized in single-layer metasurface approach. We fabricated demonstrated that focal spots separated transversely...
Here, we report the sintering of aggregated submicron cubic boron nitride (sm-cBN) at a pressure 8 GPa. The sintered cBN compacts exhibit hardness values comparable to that single crystal diamond, fracture toughness about 5-fold crystal, in combination with high oxidization temperature. Thus, another way has been demonstrated improve mechanical properties besides reducing grain size nano scale. In contrast other ultrahard similar hardness, sm-cBN aggregates are better placed for potential...
