Hybrid organic–inorganic piezoelectrics have attracted attention due to their simple synthesis, mechanical flexibility, and designability, which have promising application potential in flexible sensing and self‐powered energy harvesting devices. Although some hybrid piezoelectrics are discovered, most of their structures are limited by the perovskite‐type and often contain lead. Herein, the synthesis,...
Template methods are regarded as an important method for micro‐nano processing in the active layer of flexible tactile sensors. These template methods use physical/chemical processes to introduce micro‐nano structures on the active layer, which improves many properties including sensitivity, response/recovery time, and detection limit. However, since the processing process and applicable conditions...
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...
The emergence of Mo‐based hybrid zeolitic imidazolate frameworks (HZIFs) with MoO4 units brings substantial advantages to design and synthesize complex Mo‐based electrocatalyst that are not expected in their conventional synthesis path. Herein, as a newly proposed concept, a facile temperature‐induced on‐site conversion approach (TOCA) is developed to realize the transformation of MoO4 units to C‐Mo‐S...
There is very limited repertoire of organic ambipolar semiconductors to date. Electron donor–acceptor alternative stacking is a unique and important binary motif for 1D mixed‐stack cocrystals, opening up possibilities for the development of organic ambipolar semiconductors. Herein, four 1D mixed‐stack cocrystals using N,N′‐bis(perfluorobutyl)‐1,7‐dicyanoperylene‐3,4:9,10‐bis(dicarboximide) (PDICNF)...
Organic resistive memory (ORM) offers great promise for next‐generation high‐density multilevel‐cell (MLC) data storage. However, the fine tuning of crystalline order among its active layer still remains challenging, which largely restricts ORM behavior. Here, an exceptional solid‐state transition from disordered orientations to highly‐uniform orientation within the ORM layer is facilely triggered...
2D organic crystals exhibit efficient charge transport and field‐effect characteristics, making them promising candidates for high‐performance nanoelectronics. However, the strong Fermi level pinning (FLP) effect and large Schottky barrier between organic semiconductors and metals largely limit device performance. Herein, by carrying out temperature‐dependent transport and Kelvin probe force microscopy...
Transition metal phosphides (TMPs), especially the dual‐metal TMPs, are highly active non‐precious metal oxygen evolution reaction (OER) electrocatalysts. Herein, an interesting atom migration phenomenon induced by Kirkendall effect is reported for the preparation of cobalt–iron (Co–Fe) phosphides by the direct phosphorization of Co–Fe alloys. The compositions and distributions of the Co and Fe phosphides...
High performance and super stable all‐inorganic full‐color quantum dot light‐emitting diodes (QLEDs) are constructed by adopting solution‐processed Mg‐doped NiOx (Mg‐NiOx) nanoparticles as hole transport layer (HTL) and Al‐doped ZnO (AZO) as electron transport layer (ETL). Mg‐NiOx nanoparticles possess the advantages of low‐temperature solution processability, intrinsic stability, and controllable...
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...
The seriousness of the energy crisis and the environmental impact of global anthropogenic activities have led to an urgent need to develop efficient and green fuels. Hydrogen, as a promising alternative resource that is produced in an environmentally friendly and sustainable manner by a water splitting reaction, has attracted extensive attention in recent years. However, the large‐scale application...
Electromagnetic (EM) wave absorption materials have attracted considerable attention because of EM wave pollution caused by the proliferation of electronic communication devices. One‐dimentional (1D) structural magnetic metals have potential as EM absorption materials. However, fabricating 1D core–shell bimetallic magnetic species is a significant challenge. Herein, 1D core–shell bimetallic magnetic...
Recently, all‐inorganic halide perovskite (CsPbX3, (X = Cl, Br, and I)) nanocrystals (NCs) based hybrid architectures have attracted extensive attention owing to their distinct luminescence characteristics. However, due to stress and lattice mismatch, it is still a challenge to construct heterojunctions between perovskite NCs and the nanostructures with different lattice parameters and non‐cubic contour...
In article number 2002410, Minshen Zhu and co‐workers develop a unique spiral microelectrode that is actuated by the intrinsic stress in layered nanomembranes to improve the energy output at a minimal footprint area, which provides a new solution of energy supply for integrated microelectronic devices.
Miniaturization of batteries lags behind the success of modern electronic devices. Neither the device volume nor the energy density of microbatteries meets the requirement of microscale electronic devices. The main limitation for pushing the energy density of microbatteries arises from the low mass loading of active materials. However, merely pushing the mass loading through increased electrode thickness...
The tactile sensor lies at the heart of electronic skin and is of great importance in the development of flexible electronic devices. To date, it still remains a critical challenge to develop a large‐scale capacitive tactile sensor with high sensitivity and controllable morphology in an economical way. Inspired by the interlocked microridges between the epidermis and dermis, herein, a highly sensitive...
Large‐area flexible pressure sensors are of paramount importance for various future applications, such as electronic skin, human–machine interfacing, and health‐monitoring devices.

Enabled by a simple...
The size effect on the cellular uptake of nanoparticles (NPs) has been extensively studied, but it is still not well understood. Herein, a reductionist approach is used to minimize all influencing factors except the particle size, and co‐exposure of different‐sized silica nanoparticles (SNPs) is adopted instead of the common single exposure. SNPs are found being internalized by Hela cells in serum‐free...
The inhibition of amyloid‐β (Aβ) aggregation by photo‐oxygenation has become an effective way of treating Alzheimer's disease (AD).
