The reduction of carbon dioxide to valuable chemicals through enzymatic processes is regarded as a promising approach for the reduction of carbon dioxide emissions. In this study, an in vitro multi‐enzyme cascade pathway is constructed for the conversion of CO2 into dihydroxyacetone (DHA). This pathway, known as FFFP, comprises formate dehydrogenase (FDH), formaldehyde dehydrogenase (FaldDH), formolase...
The traditional tris(bipyridine)ruthenium(II) complex suffers from the notorious aggregation‐caused quenching effect, which greatly compromises its electrochemiluminescence (ECL) efficiency, thus hindering further applications in biosensing and clinical diagnosis. Here, the ultrathin tetraphenylethylene‐active tris(bipyridine)ruthenium(II) derivative nanosheets (abbreviated as Ru‐TPE NSs) are synthesized...
The rapid development of wearable biosensing calls for next‐generation devices that allow continuous, real‐time, and painless monitoring of health status along with responsive medical treatment. Microneedles have exhibited great potential for the direct access of dermal interstitial fluid (ISF) in a minimally invasive manner. Recent studies of microneedle‐based devices have evolved from conventional...
Dendrimers are a family of polymers with highly branched structure, well‐defined composition, and extensive functional groups, which have attracted great attention in biomedical applications. Micelles formed by dendrimers are ideal nanocarriers for delivering anticancer agents due to the explicit study of their characteristics of particle size, charge, and biological properties such as toxicity, blood...
The recently developed defective 19‐electron half‐Heusler (HH) compounds, represented by Nb1−δCoSb, possess massive intrinsic vacancies at the cation site and thus intrinsically low lattice thermal conductivity that is desirable for thermoelectric (TE) applications. Yet the TE performance of defective HHs with a maximum figure of merit (zT) <1.0 is still inferior to that of the conventional 18‐electron...
Superlattice Films
Work function difference induces spontaneous charge donation and band bending at the interfaces of superlattices, which causes optimization effects of modulation doping and energy filtering, leading to remarkably enhanced thermoelectric performances. This optimizing strategy is successfully elucidated in 1T′‐MoTe2/Bi2Te3 superlattice films. Meanwhile, the rational manipulation of...
Interfacial charge effects, such as band bending, modulation doping, and energy filtering, are critical for improving electronic transport properties of superlattice films. However, effectively manipulating interfacial band bending has proven challenging in previous studies. In this study, (1T′‐MoTe2)x(Bi2Te3)y superlattice films with symmetry‐mismatch were successfully fabricated via the molecular...
Artificial photosynthesis for CO2 reduction coupled with water oxidation currently suffers from low efficiency due to inadequate interfacial charge separation of conventional Z‐scheme heterojunctions. Herein, an unprecedented nanoscale Janus Z‐scheme heterojunction of CsPbBr3/TiOx is constructed for photocatalytic CO2 reduction. Benefitting from the short carrier transport distance and direct contact...
Hard carbons (HCs) are extensively investigated as the potential anodes for commercialization of sodium‐ion batteries (SIBs). However, the practical deployment of HC anode suffers from the retarded Na+ diffusion at the high‐rate or low‐temperature operation scenarios. Herein, a multiscale modification strategy by tuning HC microstructure on the particle level as well as replenishing extra Na+ reservoir...
Electrocatalytic CO2 reduction reaction (CO2RR) toward formate production can be operated under mild conditions with high energy conversion efficiency while migrating the greenhouse effect. Herein, an integrated 3D open network of interconnected bismuthene arrays (3D Bi‐ene‐A/CM) is fabricated via in situ electrochemically topotactic transformation from BiOCOOH nanosheet arrays supported on the copper...
The judicious design of efficient electron mediators to accelerate the interfacial charge transfer in a Z‐scheme system is one of the viable strategies to improve the performance of photocatalysts for artificial photosynthesis. Herein, ultrathin and small‐size graphene oxide (USGO) nanosheets are constructed and employed as the electron mediator to elaborately exploit an efficient CsPbBr3‐based all‐solid‐state...
Conventional lithium–sulfur batteries often suffer from fatal problems such as high flammability, polysulfide shuttling, and lithium dendrites growth. Here, highly‐safe lithium–sulfur batteries based on flame‐retardant electrolyte (dimethoxyether/1,1,2,2‐tetrafluoroethyl 2,2,3,3‐tetrafluoropropyl ether) coupled with functional separator (nanoconductive carbon‐coated cellulose nonwoven) to resolve...
Conventional liquid electrolytes based lithium‐ion batteries (LIBs) might suffer from serious safety hazards. Solid‐state polymer electrolytes (SPEs) are very promising candidate with high security for advanced LIBs. However, the quintessential frailties of pristine polyethylene oxide/lithium salts SPEs are poor ionic conductivity (≈10−8 S cm−1) at 25 °C and narrow electrochemical window (<4 V)...
Fabrication of clinically translatable nanoparticles (NPs) as photothermal therapy (PTT) agents against cancer is becoming increasingly desirable, but still challenging, especially in facile and controllable synthesis of biocompatible NPs with high photothermal efficiency. A new strategy which uses protein as both a template and a sulfur provider is proposed for facile, cost‐effective, and large‐scale...
