Self‐Wrinkling Polymer Films
In article number 2311679, Han‐Yu Hsueh and co‐workers were inspired by the superglue fuming method for fingerprint collection and developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. The technique can be easily applied to architectures with complex outer morphologies and inner surfaces and has...
Inspired by the superglue fuming method for fingerprint collection, this study developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. High‐electronegativity groups are introduced on the substrate surface to initiate the polymerization of monomer vapors, such as ethyl cyanoacrylate, which results in the formation of a stiff poly(ethyl...
Boosting energy density and reducing the cost of lithium‐ion batteries are critical to accelerating their applications in transportation and grid energy storage. Battery design with increasing electrode thickness is an effective way to combine higher energy density and lower cost. However, the evaluation of electrodes with increased thickness is challenging and requires more attention. Here, some...
Developing highly efficient catalysts toward alkaline hydrogen oxidation reaction (HOR) and narrowing the kinetic gap between acidic and alkaline electrolytes are of great importance for the practical application of alkaline exchange membrane fuel cell . Herein, ordered Ru3Sn7/C intermetallic compound has been developed for the HOR under alkaline and acidic conditions. The authors demonstrate that...
Understanding the direct interaction of nanostructures per se with biological systems is important for biomedical applications. However, whether nanostructures regulate biological systems by targeting specific cellular proteins remains largely unknown. In the present work, self‐assembling nanomicelles are constructed using small‐molecule oleanolic acid (OA) as a molecular template. Unexpectedly, without...

In article number 2205531, Ke‐Wu Zeng and co‐workers describe the natural product oleanolic acid‐based self‐assembling nanostructures specially bind to proteasome subunit alpha 6 (PSMA6) to activate proteasome for cancer cell pyroptosis. This study opens up a new direction for the development anti‐cancer nanomedicine from natural resources.
The poor conductivity, inert charge transmission efficiency, and irreversible Na+ trapping of Na2Ti3O7 result in retardant electrons/ions transportation and deficient sodium‐ion storage efficiency, leading to sluggish reaction kinetics. To address these issues, an urchin‐like Ti2CTx/Na2Ti3O7 (Ti2C/NTO) heterostructure sphere consisting of Ti2C/NTO heterostructure nanobelts array is developed via a...
The alkaline polymer electrolyte fuel cells (APEFCs) hold great promise for using nonnoble metal‐based electrocatalysts toward the cathodic oxygen reduction reaction (ORR), but are hindered by the sluggish anodic hydrogen oxidation reaction (HOR) in alkaline electrolytes. Here, a strategy is reported to promote the alkaline HOR performance of Ru by incorporating 3d‐transition metals (V, Fe, Co, and...
Magnetic photonic crystals (PCs) possess attractive magnetic orientation, flexible pattern designability, and abundant angle‐dependent colors, providing immense potential in anticounterfeiting field. However, all‐solid magnetic PCs‐based labels generally suffer from incompatibility with screen printing techniques, and inferior environmental endurance and mechanical properties. Herein, by developing...
In contrast to the 2D organic‐inorganic hybrid Ruddlesden–Popper halide perovskites (RPP), a new class of 2D all inorganic RPP (IRPP) has been recently proposed by substituting the organic spacers with an optimal inorganic alternative of cesium cations (Cs+). Nevertheless, the synthesis of high‐membered 2D IRPPs (n > 1) has been a very challenging task because the Cs+ need to act as both spacers...
