Colloidal quantum dots (QDs) are shown to be effective as light‐harvesting sensitizers of metal oxide semiconductor (MOS) photoelectrodes for photoelectrochemical (PEC) hydrogen (H2) generation. The CdSe/CdS core/shell architecture is widely studied due to their tunable absorption range and band alignment via engineering the size of each composition, leading to efficient carrier separation/transfer...
Precious‐metal single‐atom catalysts (SACs), featured by high metal utilization and unique coordination structure for catalysis, demonstrate distinctive performances in the fields of heterogeneous and electrochemical catalysis. Herein, gold SACs are constructed on hierarchical nitrogen‐doped carbon nanocages (hNCNC) via a simple impregnation‐drying process and first exploited for electrocatalytic...
Restoring immune tolerance is the ultimate goal for rheumatoid arthritis (RA) treatment. The most reported oral or intravenous injection routes for the immunization of autoantigens cause gastrointestinal side effects, low patient compliance, and unsatisfied immune tolerance induction. Herein, the use of a transdermal microneedle patch is for the first time investigated to codeliver CII peptide autoantigen...
Fuel cells offer great promise for portable electricity generation, but their use is currently limited by their low durability, excessive operating temperatures, and expensive precious metal electrodes. It is therefore essential to develop fuel cell systems that can perform effectively using more robust electrolyte materials, at reasonable temperatures, with lower‐cost electrodes. Recently, proton...
Spintronic devices work by manipulating the spin of electrons other than charge transfer, which is of revolutionary significance and can largely reduce energy consumption in the future. Herein, ultrathin two‐dimensional (2D) non‐van der Waals (non‐vdW) γ‐Ga2O3 with room temperature ferromagnetism is successfully obtained by using supercritical CO2 (SC CO2). The stress effect of SC CO2 under different...
Terahertz Spectroscopy
In article number 2306200, Tao Zhao, Tianwu Wang, Guangyou Fang, and co‐workers generated broadband terahertz pulses by dual‐color laser‐induced air plasma. Subsequently, the interaction between terahertz waves and MXene reveals the localized charge carrier effects caused by electron‐phonon scattering. In the image, ‘e’ and ‘p’ represent electrons and phonons, respectively,...
The transport properties of charge carriers in MXene, a promising material, have been studied using terahertz time‐domain spectroscopy (THz‐TDS) to examine its potential applications in optical and electronic devices. However, previous studies have been limited by narrow frequency ranges, which have hindered the understanding of the intrinsic mechanisms of carrier transport in MXenes. To address this...
Aqueous zinc ion batteries (AZIBs) are considered promising energy storage devices because of their high theoretical energy density and cost‐effectiveness. However, the ongoing side reactions and zinc dendrite growth during cycling limit their practical application. Herein, trisodium methylglycine diacetate (Na3MGDA) additive containing the additional inert group methyl is introduced for Zn anode...
Triboelectric nanogenerators (TENGs) have manifested a remarkable potential for harvesting environmental energy and have the prospects to be utilized for various uses, for instance, self‐powered sensing devices, flexible wearables, and marine corrosion protection. However, the potential for further development of TENGs is restricted on account of their low output power that in turn is determined by...
It has been well‐established that light‐matter interactions, as manifested by diverse linear and nonlinear optical (NLO) processes, are mediated by real and virtual particles, such as electrons, phonons, and excitons. Polarons, often regarded as electrons dressed by phonons, are known to contribute to exotic behaviors of solids, from superconductivity to photocatalysis, while their role in materials’...
Electrocatalytic nitrogen reduction reaction (eNRR) is a promising method for sustainable ammonia production. Although the majority of studies on the eNRR are devoted to developing efficient electrocatalysts, it is critical to study the influence of mass transfer because of the poor N2 transfer efficiency. Herein, a novel bubble‐based microreactor (BBMR) is proposed that efficiently promotes the mass...
Magnetic resonance imaging contrast agents are frequently used in clinics to enhance the contrast between diseased and normal tissues. The previously reported poly(acrylic acid) stabilized exceedingly small gadolinium oxide nanoparticles (ES‐GdON‐PAA) overcame the problems of commercial Gd chelates, but limitations still exist, i.e., high r2/r1 ratio, long blood circulation half‐life, and no data...
Functional metamaterials can be constructed by assembling nanoparticles (NPs) into well‐ordered structures, which show fascinating properties at different length scales. Using polymer‐grafted NPs (PGNPs) as a building block, flexible composite metamaterials can be obtained, of which the structure is significantly affected by the property of polymer ligands. Here, it is demonstrated that the crystallization...
Photodynamic therapy (PDT) is extensively investigated for tumor therapy in the clinic. However, the efficacy of PDT is severely limited by the tissue penetrability of light, short effective half‐life and radius of reactive oxygen species (ROS), and the weak immunostimulatory effect. In this study, a glutathione (GSH)‐activatable nano‐photosensitizer is developed to load with arachidonic acid (AA)...
Carrier‐selective passivating contacts using transition metal oxides (TMOs) have attracted great attention for crystalline silicon (c‐Si) heterojunction solar cells recently. Among them, tantalum oxide (Ta2O5) exhibits outstanding advantages, such as a wide bandgap, good surface passivation, and a small conduction band offset with c‐Si, which is typically used as an electron‐selective contact layer...
Stable plating/stripping of Zn metal anode remains a great challenge owing to uncontrollable dendrite growth and side reactions. Ion‐sieving separators is a unique and promising solution, that possess Zn2+ permeability and promote Zn2+ transport, can effectively alleviate the abovementioned problems. Ion‐sieving on glass fiber separator by deposition of oxygen‐deficient SiOx layer via active screen...
The limited ionic conductivity and unstable interface due to poor solid–solid interface pose significant challenges to the stable cycling of solid‐state batteries (SSBs). Herein, an interfacial plasticization strategy is proposed by introducing a succinonitrile (SN)‐based plastic curing agent into the polyacrylonitrile (PAN)‐based composite polymer electrolytes (CPE) interface. The SN at the interface...
Dual‐atom catalysts exhibit higher reactivity and selectivity than the single‐atom catalysts. The pyrolysis of bimetal salt precursors is the most typical method for synthesizing dual‐atomic catalysts; however, the finiteness of bimetal salts limits the variety of dual‐atomic catalysts. In this study, a confined synthesis strategy for synthesizing dual‐atomic catalysts is developed. Owing to the in...
Normally, only noncentrosymmetric structure of the materials can potentially be piezoelectric. Thus, it is limited in the field of piezoelectricity for the centrosymmetric structure of the material. In this work, the performance of piezoelectricity is successfully achieved from centrosymmetric SrFeO3‐x by modulating oxygen vacancies, which have a surface piezoelectric potential up to 93 mV by using...
Dual single‐atom catalysts (DSACs) are promising for breaking the scaling relationships and ensuring synergistic effects compared with conventional single‐atom catalysts (SACs).
