Constructing a powerful photocatalytic system that can achieve the carbon dioxide (CO2 ) reduction half-reaction and water (H2 O) oxidation simultaneously is very challenging but meaningful task. Herein, porous material with crystalline topological network, named viCOF-bpy-Re, was rationally synthesized by incorporating rhenium complexes as reductive sites triazine ring structures oxidative via robust -C=C- bond linkages. The charge-separation ability of viCOF-bpy-Re promoted low polarized...
Abstract Bioproduction of renewable chemicals is considered as an urgent solution for fossil energy crisis. However, despite tremendous efforts, it still challenging to generate microbial strains that can produce target biochemical high levels.

Recycling precious from waste is promising strategy, here we tactfully utilize light irradiation as an environmental‐friendly energy‐saving adjunctive strategy to promote reduction metal ions, thereby improving adsorption capacity kinetics. A newly light‐sensitive covalent organic framework (PP‐COF) was synthesized illustrate effectiveness feasibility this...
Purpose The rapid innovation of artificial intelligence (AI) technology promotes the prosperity AI product market. However, consumers seem to have negative attitudes (e.g. prejudice, aversion) toward products and services. Those are rooted in fear that might replace humans. authors thus propose turning image from substitutes facilitators can alleviate identity threat perception. This paper aims examine how (facilitators vs substitutes) influences consumer evaluation explores underlying...

GaN-based Micro-LED has been widely regarded as the most promising candidate for next generation of revolutionary display technology due to its advantages high efficiency, brightness and stability. However, typical micro-fabrication process would leave a great number damages on sidewalls LED pixels, especially Micro-LEDs, thus reducing light emitting efficiency. In this paper, sidewall passivation methods were optimized by using acid-base wet etching SiO2 layer passivation. The optical...

Abstract A recent theory suggests that electrons enter electron sheaths at an Bohm velocity given by ( T e / m ) 1/2 instead of the thermal as conventionally assumed. To test this theory, flux density ratio Γ e,se /Γ i,se and ions entering their respective was directly measured via almost continuous i area scanning. The value agrees with predictions assuming velocity. associated criterion have not been found. If such theories are true, or ion presheath drops will be very different from...
