Oxygen evolution reaction (OER) plays a critical role in energy conversion technologies. Significant progress has been made in alkaline conditions. In contrast, it remains a challenge to develop stable OER electrocatalysts in acidic conditions. Herein, a new strategy is reported to stabilize single atoms integrated into cobalt oxide spinel structure with interstitial carbon (Ru0.27Co2.73O4), where...
The growth state of tumor cells is strictly affected by the specific abnormal redox status of the tumor microenvironment (TME). Moreover, redox reactions at the biological level are also central and fundamental to essential energy metabolism reactions in tumors. Accordingly, anti‐tumor nanodrugs targeting the disruption of this abnormal redox homeostasis have become one of the hot spots in the field...
MnTe emerges as an enormous potential for medium‐temperature thermoelectric applications due to its lead‐free nature, high content of Mn in the earth's crust, and superior mechanical properties. Here, it is demonstrate that multiple valence band convergence can be realized through Pb and Ag incorporations, producing large Seebeck coefficient. Furthermore, the carrier concentration can be obviously...
Hydrogels are widely used in tissue engineering, soft robotics and wearable electronics. However, it is difficult to achieve both the required toughness and stiffness, which severely hampers their application as load‐bearing materials. This study presents a strategy to develop a hard and tough composite hydrogel. Herein, flexible SiO2 nanofibers (SNF) are dispersed homogeneously in a polyvinyl alcohol...
Owing to the outstanding comprehensive properties of high energy density, excellent cycling ability, and reasonable cost, Ni‐rich layered oxides (NCM) are the most promising cathode for lithium‐ion batteries (LIBs). To further enhance the specific capacity of Ni‐rich layered oxides, it is necessary to increase the cut‐off voltage to a higher level. However, a higher cut‐off voltage can lead to substantial...
The utility of electrochemical active biofilm in bioelectrochemical systems has received considerable attention for harvesting energy and chemical products. However, the slow electron transfer between biofilms and electrodes hinders the enhancement of performance and still remains challenging. Here, using Fe3O4 /L‐Cys nanoparticles as precursors to induce biomineralization, a facile strategy for the...
Cellular senescence, a vulnerable state of growth arrest, has been regarded as a potential strategy to weaken the resistance of tumor cells, leading to dramatic improvements in treatment efficacy. However, a selective and efficient strategy for inducing local tumor cellular senescence has not yet been reported. Herein, piezoelectric catalysis is utilized to reduce intracellular NAD+ to NADH for local...
This review focuses on the advanced design and optimization of nanostructured zinc–air batteries (ZABs), with the aim of boosting their energy storage and conversion capabilities. The findings show that ZABs favor porous nanostructures owing to their large surface area, and this enhances the battery capacity, catalytic activity, and life cycle. In addition, the nanomaterials improve the electrical...
Smart luminescent materials that have the ability to reversibly adapt to external environmental stimuli and possess a wide range of responses are continually emerging, which place higher demands on the means of regulation and response sites. Here, europium ions (Eu3+)‐directed supramolecular metallogels are constructed by orthogonal self‐assembly of Eu3+ based coordination interactions and hydrogen...
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...
Various natural polymers offer sustainable alternatives to petroleum‐based adhesives, enabling the creation of high‐performance engineered materials. However, additional chemical modifications and complicated manufacturing procedures remain unavoidable. Here, a sustainable high‐performance engineered composite that benefits from bonding strategies with multiple energy dissipation mechanisms dominated...
It is deemed as a tough yet profound project to comprehensively cope with a range of detrimental problems of lithium–sulfur batteries (LSBs), mainly pertaining to the shuttle effect of lithium polysulfides (LiPSs) and sluggish sulfur conversion. Herein, a Co2P‐Fe2P@N‐doped carbon (Co2P‐Fe2P@NC) Mott–Schottky catalyst is introduced to enable bidirectionally stimulated sulfur conversion. This catalyst...
Radiation resistance in breast cancer resulting in residual lesions or recurrence is a significant cause to radiotherapy failure. Cancer‐associated fibroblasts (CAFs) and radiotherapy‐induced senescent CAFs can further lead to radiation resistance and tumor immunosuppressive microenvironment. Here, an engineering cancer‐cell‐biomimetic nanoplatform is constructed for dual‐targeted clearance of CAFs...
The β‐relaxation is one of the major dynamic behaviors in metallic glasses (MGs) and exhibits diverse features. Despite decades of efforts, the understanding of its structural origin and contribution to the overall dynamics of MG systems is still unclear. Here two palladium‐based Pd─Cu─P and Pd─Ni─P MGs are reported with distinct different β‐relaxation behaviors and reveal the structural origins for...
Enantiomers (opposite chiral molecules) usually exhibit different effects when interacting with chiral agents, thus the identification and separation of enantiomers are of importance in pharmaceuticals and agrochemicals. Here an optical approach is proposed to enantioselective trapping of multiple pairs of enantiomers by a focused hybrid polarized beam. Numerical results indicate that such a focused...
Bispecific antibodies possess exceptional potential as therapeutic agents due to their capacity to bind to two different antigens simultaneously. However, challenges pertain to unsatisfactory stability, manufacturing complexity, and limited tumor penetration hinder their broad applicability. In this study, a versatile technology is presented for the rapid generation of bispecific nanobody‐aptamer...
To date, the excellent mass‐catalytic activities of Pt single‐atoms catalysts (Pt‐SACs) toward hydrogen evolution reaction (HER) are categorically confirmed; however, their high current density performance remains a challenge for practical applications. Here, a binder‐free approach is exemplified to fabricate self‐standing superhydrophilic‐superaerphobic Pt‐SACs cathodes by directly anchoring Pt‐SAs...
Chimeric antigen receptor natural killer (CAR‐NK) cell therapy represents a potent approach to suppressing tumor growth because it has simultaneously inherited the specificity of CAR and the intrinsic generality of NK cells in recognizing cancer cells. However, its therapeutic potency against solid tumors is still restricted by insufficient tumor infiltration, immunosuppressive tumor microenvironments,...
Osteoarthritis (OA) is a typical joint degenerative disease that is prevalent worldwide and significantly affects the normal activities of patients. Traditional treatments using diclofenac (DCF) as an anti‐inflammatory drug by oral administration and transdermal delivery have many inherent deficiencies.
