Cobalt spinel oxides, which consist of tetrahedral site (AO4) and octahedral site (BO6), are a potential group of transition metal oxides (TMO) for electrocatalytic nitrate reduction reactions to ammonia (NRA). Identifying the true active site in spinel oxides is crucial to designing advanced catalysts. This work reveals that the CoO6 site is the dominant site for NRA through the site substitution...
Nanowire Composites
In article number 2304327, De Gong and co‐workers develop a novel sandwich‐structured assembly strategy to fabricate flexible MXene/AgNW composite thin films with ultrahigh electrical conductivity (up to 27193 S cm−1) and superior multifunctionality. Due to their exceptional temperature‐tolerance and superior versatility, these films demonstrate great potentials in various application...
Flexible composite films have attracted considerable attention due to great potential for healthcare, telecommunication, and aerospace. However, it is still challenging to achieve high conductivity and multifunctional integration, mainly due to poorly designed composite structures of these films. Herein, a novel sandwich‐structured assembly strategy is proposed to fabricate flexible composite thin...
Assembling quantum dots (QDs) into van der Waals (vdW)‐layered superstructure holds great promise for the development of high‐energy‐density metal anode. However, designing such a superstructure remains to be challenging. Here, a chemical‐vapor Oriented Attachment (OA) growth strategy is proposed to achieve the synthesis of vdW‐layered carbon/QDs hybrid superlattice nanosheets (Fe7S8@CNS) with a large...
Micro‐supercapacitors (MSCs) are an important energy storage component for future miniaturized electronic systems, yet their key performance indexes such as high‐frequency response, energy density, and cycle life still have a large room to be improved. Herein, a laser‐processed carbon‐titanium carbide heterostructure (LCTH) electrode is demonstrated, which can excellently address the above key challenges...
“Blockchain‐Like” Interface Moderation Method
Carbon black as a “chain” to guide the charge transfer effectively promotes the F‐ transfer into the metal‐organic framework (MOF), and through the redox reaction stored in the MOF “block”. This interface moderation method effectively improves the fluoride removal performance of the MOF electrode. More details can be found in article number 2205619 by...
Metal‐organic frameworks (MOF) have attracted extensive attention due to their ultra‐high specific surface area and tunable structure, the mechanism of direct utilization for capacitive deionization (CDI) defluorination remains undefined. Here, MIL‐101(Cr) with ultra‐high specific surface area, high water stability, and open metal sites (OMSs) is prepared by a hydrothermal method for defluorination...
Poor stability of nanostructured electrocatalysts at rigorous industrial conditions significantly inhibits their performances in practical electrolyzers. Although many substrate‐supported nanostructured electrocatalysts present attractive performance at small currents, they cannot sustain industry‐level high current densities for long‐term operation. Herein, by chemically organizing nanoscale electrocatalysts...
Macrophages play essential roles in the progression of rheumatoid arthritis (RA), which are polarized into the pro‐inflammatory M1 phenotype with significant oxidative stress and cytokines excretion. Herein, an active targeting nanomedicine based on metal‐organic frameworks (MOFs) to re‐educate the diseased macrophages for RA therapy is reported. The MOFs are prepared via coordination between tannic...
Additives are often used to adjust the morphology of the active layer to improve the performance of organic solar cells (OSCs). Here, taking typical high‐efficiency non‐fullerene systems as examples, the effect of the additive on the device performance in non‐fullerene OSCs is systematically investigated. Surprisingly, an unpresented VOC change is observed in the opposite direction of the two typical...
Lithium (Li) metal has been generally noticed as the most prospective anode for next‐generation batteries attributed to its outstanding theoretical capacity and low electrochemical potential. Nevertheless, the unstable solid‐electrolyte interphase (SEI) and uncontrollable dendrite growth cause poor reversibility and fetter the practical application of Li metal anodes. Herein, a new organic–inorganic...
Uniform deposition and distribution of lithium ion (Li+) on the surface of lithium metal anode is crucial for long‐life and high‐safety lithium metal batteries. However, the preparation of stable solid–electrolyte interphase (SEI) is mostly based on trial and error in the absence of guideline. Herein, covalent organic framework (COF) with high Young's modulus and low surface work function is in situ...
Clinically, inhibition of both bacterial infection and excessive inflammation is a crucial step for improved wound treatments. Herein, the fabrication of near‐infrared‐light (NIR)‐activatable deoxyribonuclease (DNase)–carbon monoxide (CO)@mesoporous polydopamine nanoparticles (MPDA NPs) is demonstrated for efficient elimination of methicillin‐resistant Staphylococcus aureus (MRSA) biofilms and the...
In recent years, atomically thin superconductors, including atomically thin elemental superconductors, single layer FeSe films, and few‐layer cuprate superconductors, have been studied extensively. This hot research field is mainly driven by the discovery of significant superconductivity enhancement and high‐temperature interface superconductivity in single‐layer FeSe films epitaxially grown on SrTiO...
Understanding the mechanical stability of granular‐armored liquid marbles is prerequisite for their applications including encapsulation, sensors, microreactions, and miniaturized liquid storage. Most liquid marbles are armored with agglomerated granular structure which complicates the wetting and interacting states of particles, hence, impeding one from understanding the effect of granular size on...
Inspired by the hierarchically helical structure of classical thermal insulation material—wool, a stretchable heating carbon nanotube (CNT) fiber is created with excellent mechanical and heating properties. It can be stretched by up to 150% with high stability and reversibility, and a good thermal insulation is achieved from a large amount of formed hierarchically helical voids inside. Impressively,...
