Lubricant‐infused slippery surface exhibits a series of superior properties such as pressure tolerance, self‐healing, oil‐repellence, etc. Especially when being applied in an aqueous environment, the reliable bubble manipulating ability of slippery surface offers great opportunities to develop advanced systems in the field of gas transport, water splitting, etc. To improve the strength and the functionality...
High‐performance flexible strain sensors are key components for the next generation of wearable health monitoring devices. Here, the authors have fabricated a novel strain sensor based on gold nanoparticles (AuNPs) interconnected by flexible and responsive molecular linkers. The combination of conductive AuNPs (25 nm in diameter) with tetra(ethylene glycol) dithiol (SH‐TEG‐SH) linkers yields a covalent...
Invoking the occurrence of pyroptosis is an emerging strategy for the treatment of cancer. However, the practical applications of pyroptosis for cancer therapy are currently hindered due to the lack of tumor‐specific and efficient pyroptotic agents in vivo. Herein, a virus‐spike tumor‐activatable pyroptotic agent (VTPA) for cancer‐specific therapy is reported. The VTPA is composed of an organosilica...
Despite the vast variety of colloidal superstructures available in soft matter photonics, it remains challenging to balance the trade‐off between their optical microstructures and material processability. By synergizing colloidal photonics and dynamic chemistry, a type of photonic “plasticine” with characteristics of uniform structural colors, high processability, and self‐healing is demonstrated...
To advance the understanding of cardiomyocyte (CM) identity and function, appropriate tools to isolate pure primary CMs are needed. A label‐free method to purify viable CMs from mouse neonatal hearts is developed using a simple particle size‐based inertial microfluidics biochip achieving purities of over 90%. Purified CMs are viable and retained their identity and function as depicted by the expression...
Lubricant‐infused slippery surface shows promising applications in regulating both liquid and gas interactions. In article number 2007803, Cunming Yu, Moyuan Cao, and co‐workers design a suspension bridge‐inspired slippery track possessing tough yet flexible feature. Taking advantages of the improved structure, this sliced track can achieve a series of underwater gas manipulating processes including...
Efficient light‐stimulated hydrogen generation from top–down produced highly doped n‐type silicon nanowires (SiNWs) with silver nanoparticles (AgNPs) in water‐containing medium under white light irradiation is reported. It is observed that SiNWs with AgNPs generate at least 2.5 times more hydrogen than SiNWs without AgNPs. The authors’ results, based on vibrational, UV–vis, and X‐ray spectroscopy...
Resistive switching (RS), an electric property based on the forming and rupture of conductive filaments in metal‐insulator‐metal structures, has attracted intensive attention due to its potential application in next generation energy‐efficient and area‐efficient memory devices. In situ studies of the RS effect are urgently needed for its mechanism understanding and memristive performance improvement...
The durability issue of triboelectric nanogenerators (TENGs) still limits its practical application for long‐term operation, especially in harvesting water energy, which is one of the most widespread energies in nature. Attempting to ameliorate this, fluorinated graphene (FG) with unique triboelectric negativity and superhydrophobic property is introduced to serve as a new triboelectric and protective...
Yolk–shell magnetic mesoporous microspheres exhibit potential applications in biomedicine, bioseparation, and catalysis. Most previous reports focus on establishing various interface assembly strategies to construct yolk–shell mesoporous structures, while little work has been done to control their surface topology and study their relevant applications. Herein, a unique kind of broccoli‐like yolk–shell...
A new family of transition‐metal monosilicides (MSi, M = Ti, Mn, Fe, Ru, Ni, Pd, Co, and Rh) electrocatalysts with superior electrocatalytic performance of hydrogen evolution is reported, based on the computational and experimental results. It is proposed that these MSi can be synthesized within several minutes by adopting the arc‐melting method. The previously reported RuSi is not only fabricated...
Up to now, the silicon‐graphite anode materials with commercial prospect for lithium batteries (LIBs) still face three dilemmas of the huge volume effect, the poor interface compatibility, and the high resistance. To address the above challenges, micro–nano structured composites of graphite coating by ZnO‐incorporated and carbon‐coated silicon (marked as Gr@ZnO‐Si‐C) are reasonably synthesized via...
Acute kidney injury (AKI) is frequently triggered by abundant reactive oxygen/nitrogen species (RONS) and leads to high morbidity and mortality in clinic. Unfortunately, the current clinical treatment options are only limited to supportive care, and hence, the development of nano‐antioxidants with high kidney enrichment is an attractive novel strategy for AKI management. Herein, self‐assembled ultrasmall...
For decades, nanoscale metal–organic frameworks (nMOFs) have attracted extensive interest in biomedicine due to their distinct characteristics, including facile synthesis, porous interior, and tunable biocompatibility. With high porosity, versatile nMOFs allow for the facile encapsulation of various therapeutic agents with exceptionally high payloads. Constructed from metal ions and organic linkers...
In article number 2006176, Peggy P. Y. Chan, Vashe Chandrakanthan, and co‐workers develop a label‐free method to purify beating cardiomyocytes from neonatal mouse hearts using a simple particle size‐based inertial microfluidics biochip. Biophysical phenotyping analysis of these sorted cardiomyocytes show distinct and consistent physico‐mechanical and cellular phenotypes of primary cardiomyocytes....
Clear recognition and rational construction of suitable active center for specific reaction is always of great significance in designing highly efficient catalysts. Herein, a dual‐active‐site copper catalyst (DAS‐Cu) containing both CuN3 and CuN4 sites is reported. Such catalysts show extremely high catalytic performance (yield: up to 97%) toward oxyphosphorylation of alkenes, while catalysts with...
Insufficient T‐cell infiltration seriously hinders the efficacy of tumor immunotherapy. Induction of immunogenic cell death (ICD) is a potentially feasible approach to increase T‐cell infiltration. Since ionizing radiation can only induce low‐level ICD, this study constructs Cu‐based nanoscale coordination polymers (Cu‐NCPs) with mixed‐valence (Cu+/Cu2+), which can simultaneously and independently...
Rechargeable alkali metal‐ion batteries (AMIBs) are receiving significant attention owing to their high energy density and low weight. The performance of AMIBs is highly dependent on the electrode materials. It is, therefore, quite crucial to explore suitable electrode materials that can fulfil the future requirements of AMIBs. Herein, a hierarchical hybrid yolk–shell structure of carbon‐coated iron...
