A strategy of microcrystalline aggregation is proposed to fabricate energy storage electrode with outstanding capacity and stability. Carbon‐rich electrode (BDTG) functionalized with benzo[1,2‐b:4,5‐b′]dithiophene units and butadiyne segments are prepared. The linear conjugate chains pack as microcrystalline nanofibers on nanoscale, which further aggregates to form a porous interpenetrating network...
Although the layered vanadium oxide‐based materials have been considered to be one of the candidates for aqueous Zn‐ion batteries (AZIBs), it still faces inevitable challenges of unsatisfactory capacities and sluggish kinetics because of strong electrostatic interactions between Zn‐ions and structure lattice. This work addresses the strategy of pre‐inserting guest materials to vanadium oxide cathode...
The widespread acceptance of nonaqueous rechargeable metal–gas batteries, known for their remarkably high theoretical energy density, faces obstacles such as poor reversibility and low energy efficiency under high charge–discharge current densities. To tackle these challenges, a novel catalytic cathode architecture for Mg–CO2 batteries, fabricated using a one‐pot electrospinning method followed by...
The unsatisfactory power conversion efficiency (PCE) and long‐term stability of tin perovskite solar cells (TPSCs) restrict its further development as alternatives to lead perovskite solar cells (LPSCs). Considerable research has focused on the negative impacts of O2 and H2O, while discussions about degradation mechanism in an inert atmosphere remains insufficient. Herein, the light‐induced autoxidation...
Covalent organic frameworks (COFs) with precisely controllable structures and highly ordered porosity possess great potential as electrocatalysts for hydrogen evolution reaction (HER). However, the catalytic performance of pristine COFs is limited by the poor active sites and low electron transfer. Herein, to address these issues, the conductive carbon nanotubes (CNTs) are coated by a defined structure...
Cadmium sulfide (CdS) is a photocatalyst widely used for efficient H2 production under visible light irradiation, due to its narrow bandgap and suitable conduction band position. However, the fast recombination of carriers results in their low utilization. In order to improve photocatalytic hydrogen production, it reports the successful introduction of metallic Cd and S vacancies on CdS nanorods (CdS...
Coupling the photoproduction of solar fuel and value‐added chemicals is highly attractive, as it maximizes the utilization of incident sunlight and the economic value of photocatalytic reactions. Constructing intimate semiconductor heterojunction for these reactions is highly desirable due to accelerated charge separation at the interfacial contact, but is challenged by material synthesis. Here, an...
Heteroatoms Fe, F co‐doped NiO hollow spheres (Fe, F‐NiO) are designed, which simultaneously integrate promoted thermodynamics by electronic structure modulation with boosted reaction kinetics by nano‐architectonics. Benefiting from the electronic structure co‐regulation of Ni sites by introducing Fe and F atoms in NiO , as the rate‐determined step (RDS), the Gibbs free energy of OH* intermediates...
High operating temperature (HOT) broadband photodetectors are urgently necessary for extreme condition applications in infrared‐guided missiles, infrared night vision, fire safety imaging, and space exploration sensing. However, conventional photodetectors show dramatic carrier mobility decreases and carrier losses with low photoresponsivity at HOT due to the increased carrier scattering in channels...
Broadband Photodetectors
In article number 2206590, Zemin Zhang, Junru Wang, Qingliang Feng, and co‐workers present large‐area Schottky junction of BP/PtSe2 films‐based nano‐device arrays towards high operating temperature broadband photodetection from 532 to 2200 nm at 470 K via a depletion enhanced photocarrier dynamics strategy. The photodetectors show a state‐of‐the‐art operating temperature up...
Uranium extraction from natural seawater is one of the most promising routes to address the shortage of uranium resources. By combination of ligand complexation and photocatalytic reduction, porous framework‐based photocatalysts have been widely applied to uranium enrichment. However, their practical applicability is limited by poor photocatalytic activity and low adsorption capacity. Herein, atomically...
Dysregulation of microRNAs (miRs) is the hallmark of triple‐negative breast cancer (TNBC), which is closely involved with its growth, metastasis, and recurrence. Dysregulated miRs are promising targets for TNBC therapy, however, targeted and accurate regulation of multiple disordered miRs in tumors is still a great challenge. Here, a multi‐targeting and on‐demand non‐coding RNA regulation nanoplatform...
In this paper, a quaternary dielectric soft‐contact rotary triboelectric nanogenerator (QDSR‐TENG) of low frictional resistance is fabricated for combining TENG with a shape memory alloy (SMA) engine. The introduction of rabbit fur brush and FEP brush results in charge pumps with a partially soft contact structure. Benefiting from the low friction loss of the structure, the QDSR‐TENG can operate stably...
Triboelectric nanogenerators (TENGs) have intrigued scientists for their potential to alleviate the energy shortage crisis and facilitate self‐powered sensors. Triboelectric interfaces containing triboelectric functionalized molecular groups and tunable surface charge densities are important for improving the electrical output capability of TENGs and the versatility of future electronics. In this...
Metal‐organic frameworks (MOFs) fillers are emerging for composite polymer electrolytes (CPEs). Enhancing Lewis acid–base interaction (LABI) among MOFs, polymer and Li‐salt is expected to promote Li+‐transport. However, it is unclear how to customize a strong LABI interface. The large surface‐area of classical MOFs also interferes with clarifying the LABI influence on Li+‐transport. Herein, Bi3+ as...
Severe inflammation and myogenic differentiation disorder are the major obstacles to skeletal muscle healing after injury. MicroRNAs (miRNAs) play an important role as regulatory molecules during the process of muscle healing, but the detailed mechanism of miRNA‐mediated intercellular communication between myoblasts and macrophages remains unclear. Here, it is reported that myoblasts secrete miRNAs‐enriched...
Macrophage Polarization
In article number 2201957, Xiliang Shang, Shiyi Chen, Jiwu Chen, and co‐workers find that myoblast‐derived exosomes modulate macrophage polarization and contribute to muscle fibrosis within the post‐injury inflammatory environment, while the miRNA inhibitor‐loaded liposomes brake the vicious circle, induce M2 polarization, relieve the inflammatory response, and promote the...
Exploring antibacterial nanomaterials with excellent catalytic antibacterial properties has always been a hot research topic.
