The commercialization of silicon anode for lithium‐ion batteries has been hindered by severe structure fracture and continuous interfacial reaction against liquid electrolytes, which can be mitigated by solid‐state electrolytes. However, rigid ceramic electrolyte suffers from large electrolyte/electrode interfacial resistance, and polymer electrolyte undergoes poor ionic conductivity, both of which...

Bioinspired synthesis and biosynthesis are often complementary. The study and understanding of the biomineralization process of magnetosomes can provide important guidance to the chemical synthesis of magnetosomes‐like Fe3O4 nanoparticles. Meanwhile, the in‐depth investigations of bioinspired syntheses can in turn bring us closer to nature and reveal the mechanism of biomeralization...
Iron oxide nanoparticles are a kind of important biomedical nanomaterials. Although their industrial‐scale production can be realized by the conventional coprecipitation method, the controllability of their size and morphology remains a huge challenge. In this study, a kind of synthetic polypeptide Mms6‐28 which mimics the magnetosome protein Mms6 is used for the bioinspired synthesis of Fe3O4 nanoparticles...
MXenes have demonstrated significant potential in electrochemical energy storage, particularly in supercapacitors, owing to their exceptional properties. The surface terminal groups of MXene play a pivotal role in pseudocapacitive mechanism. Considering the hindered electrolyte ion transport caused by –F terminal groups and the limited ion binding sites associated with –O terminal groups, this study...
Photoresponsive nitric oxide (NO)‐releasing materials (NORMs) enable the spatiotemporal delivery of NO to facilitate their potential applications in physiological conditions. Here two novel metal–organic frameworks (MOFs)‐based photoactive NORMs achieved by the incorporation of prefunctionalized NO donors into the photosensitive Fe‐MOFs via a postmodification strategy is reported. The modified Fe‐MOFs...
Single‐atom catalysts (SACs) are promising cathode materials for addressing issues faced by lithium–sulfur batteries. Considering the ample chemical space of SACs, high‐throughput calculations are efficient strategies for their rational design. However, the high throughput calculations are impeded by the time‐consuming determination of the decomposition barrier (Eb) of Li2S. In this study, the effects...
The requirements for high energy and green primary explosives are more and more stringent because of the rising demand in the application of micro initiation explosive devices. Four new energetic compounds with powerful initiation ability are reported and their performances are experimentally proven as designed, including non‐perovskites ([H2DABCO](H4IO6)2·2H2O, named TDPI‐0) and perovskitoid energetic...
Developing effective catalysts to degrade chemical warfare agents is of great significance. Herein, a mesoporous MIL‐101(Cr) composite material dangled with porphyrin molecules (denote as TCPP@MIL‐101(Cr), TCPP = tetra(4‐carboxyphenyl)porphyrin) is reported, which can be used as a heterogeneous photocatalyst for detoxification of mustard gas simulants 2‐chloroethyl ethyl sulfide (CEES) to 2‐chloroethyl...
The progression and metastasis of solid tumors rely strongly on neovascularization. However, angiogenesis inhibitors alone cannot meet the needs of tumor therapy. This study prepared a new drug conjugate (PTX‐GSHP‐CYS‐ES2, PGCE) by combining polysaccharides (heparin without anticoagulant activity, GSHP), chemotherapeutic drugs (paclitaxel, PTX), and antiangiogenic drugs (ES2). Furthermore, a tumor‐targeted...
The practical application of Li‐S batteries is seriously hindered due to its shuttle effect and sluggish redox reaction, which requires a better functional separator to solve the problems. Herein, polypropylene separators modified by MoS2 nanosheets with atomically dispersed nickel (Ni‐MoS2) are prepared to prevent the shuttle effect and facilitate the redox kinetics for Li‐S batteries. Compared with...
Hollow nanostructured hosts are important scaffolds to achieve high sulfur loading, fast charge transfer, and conspicuous restraint of lithium polysulfides (LiPSs) shuttling in lithium‐sulfur (Li‐S) batteries. However, developing high‐efficiency hollow hosts for improving utilization and conversion of aggregated sulfur in the hollow chamber remains a longstanding challenge. Herein, hollow N‐doped...
Employing low‐dimensional perovskite has been proven to be a promising approach to enhance the efficiency and stability of perovskite solar cells. Here, thiopheniformamidine hydrochloride is introduced into CH3NH3PbI3‐based printable mesoscopic perovskite solar cells, to form 1D iodide lead thiophenamidine (TFPbI3) in situ. This judiciously designed low‐dimensional perovskite can effectively passivate...
An optimized charge transporting layer (CTL) under perovskite film is crucial for efficient photoelectric devices. Here, a new water‐soluble conjugated polyeletrolyte (CPE) with CH3NH3+ (MA+) counterion termed as TB(MA) is used as the hole transporting layer (HTL) instead of the acidic poly(3,4‐ethylenedioxythiophene):poly‐styrene sulfonate (PEDOT:PSS) in sky‐blue perovskite light‐emitting diodes...
Chemodynamic therapy (CDT), which induces cell death by decomposing high levels of H2O2 in tumor cells into highly toxic ·OH, is recognized as a promising antineoplastic approach. However, current CDT approaches are often restricted by the highly controlled and upregulated cellular antioxidant defense. To enhance ·OH‐induced cellular damage by CDT, a covalent organic framework (COF)‐based, ferrocene...
In article number 2002169, Wu Wei, Yan Li, Tiangang Liu, and co‐workers develop a novel detection technology, nanopore targeted sequencing (NTS), for the accurate and comprehensive detection of SARS‐CoV‐2 and other respiratory viruses. This detection technology is suitable for the identification of suspected COVID‐19 cases and can also monitor mutations in the virus and the type of virus.
The ongoing global novel coronavirus pneumonia COVID‐19 outbreak has engendered numerous cases of infection and death. COVID‐19 diagnosis relies upon nucleic acid detection; however, currently recommended methods exhibit high false‐negative rates and are unable to identify other respiratory virus infections, thereby resulting in patient misdiagnosis and impeding epidemic containment. Combining the...
Hexagonal nickel‐organic framework (Ni‐MOF) [Ni(NO3)2·6H2O, 1,3,5‐benzenetricarboxylic acid, 4‐4′‐bipyridine] is fabricated through a one‐step solvothermal method. The {001} crystal plane is exposed to the largest hexagonal surface, which is an ideal structure for electron transport and ion diffusion. Compared with the surrounding rectangular crystal surface, the ion diffusion length through the {001}...
