The poor reversibility and stability of Zn metal anode (ZMA) caused by uncontrolled Zn deposition behaviors and serious side reactions severely impeded the practical application of aqueous Zn metal battery. Herein, a liquid‐dynamic and self‐adaptive protective layer (LSPL) was constructed on the ZMA surface for inhibiting dendrites and by‐products formation. Interestingly, the outer LSPL consists...
The dendrite growth and parasitic reactions that occur on Zn metal anode (ZMA)/electrolyte interface hinder the development of aqueous zinc ion batteries (AZIBs) in next‐generation renewable energy storage systems. Fortunately, reconstructing the inner Helmholtz layer (IHL) by introducing an electrolyte additive, is viewed as one of the most promising strategies to harvest the stable ZMA. Herein,...
2D materials with atomic‐scale thickness and mechanical robustness are required for flexible devices. The superior optoelectronic properties and high‐Z atoms in metal halide perovskites render them desirable for X‐ray detection, but the intrinsic brittleness is an obstacle hampering the applications in flexible detectors. Herein, an interfacial engineering strategy is demonstrated for the epitaxial...
As representative extended planar defects, crystallographic shear (CS) planes, namely Wadsley defects, play an important role in modifying the physical and chemical properties of metal oxides. Although these special structures have been intensively investigated for high‐rate anode materials and catalysts, it is still experimentally unclear how the CS planes form and propagate at the atomic scale....

In article number 2302686, Jiurong Liu, Zhihui Zeng, and co‐workers report a type of N‐doped carbon nanotube encapsulated CoNi alloy nanocomposites with diverse heterostructures, which deliver excellent electromagnetic wave absorption performance involving a minimum reflection loss of −84.0 dB at the thickness of 3.2 mm and a maximum effective bandwidth of 4.3 GHz.
Developing carbon encapsulated magnetic composites with rational design of microstructure for achieving high‐performance electromagnetic wave (EMW) absorption in a facile, sustainable, and energy‐efficiency approach is highly demanded yet remains challenging. Here, a type of N‐doped carbon nanotube (CNT) encapsulated CoNi alloy nanocomposites with diverse heterostructures are synthesized via the facile,...
Oligomerization of antimicrobial peptides (AMPs) is critical in their effects on pathogens. LL‐37 and its truncated fragments are widely investigated regarding their structures, antimicrobial activities, and application, such as developing new antibiotics. Due to the small size and weak intermolecular interactions of LL‐37 fragments, it is still elusive to establish the relationship between oligomeric...
Silica is regarded as a promising anode material for lithium‐ion batteries (LIBs) because of its high theoretical capacity. However, large volume variation and poor electrical conductivity are limiting factors for the development of SiO2 anode materials. To solve this problem, combining SiO2 with a conductive phase and designing hollow porous structures are effective ways. In this work, The Co(II)‐EDTA...
Extensive efforts have been devoted to the design of organic photothermal agents (PTAs) that absorb in the second near‐infrared (NIR‐II) bio‐window, which can provide deeper tissue penetration that is significant for phototheranostics of lethal brain tumors. Herein, the first example of NIR‐II‐absorbing small organic molecule (N1) derived from perylene monoamide (PMI) and its bio‐application after...
Single‐atom alloys (SAAs) display excellent electrocatalytic performance by overcoming the scaling relationships in alloys. However, due to the lack of a unique structure engineering design, it is difficult to obtain SAAs with a high specific surface area to expose more active sites. Herein, single Co atoms are immobilized on Pd metallene (Pdm) support to obtain Co/Pdm through the design of the engineered...
RNA molecules have emerged as increasingly attractive biomaterials with important applications such as RNA interference (RNAi) for cancer treatment and mRNA vaccines against infectious diseases. However, it remains challenging to engineer RNA biomaterials with sophisticated functions such as non‐covalent light‐switching ability. Herein, light‐responsive RNA‐protein nanowires are engineered to have...
Stimuli‐responsive DNA hydrogels are promising candidates for cancer treatment, as they not only possess biocompatible and biodegradable 3D network structures as highly efficient carriers for therapeutic agents but also are capable of undergoing programmable gel‐to‐solution transition upon external stimuli to achieve controlled delivery. Herein, a promising platform for highly efficient photothermal‐chemo...
Kidney transplantation is the most effective therapy for patients with end‐stage renal disease. However, antibody‐mediated rejection (ABMR) threatens long‐term survival of renal grafts. Although ABMR can be controlled by donor‐specific antibody clearance and B‐ or (and) plasma‐cells inhibition, the treatment often causes severe side effects in patients. Therefore, there is need to explore site‐specific...
Germanium (Ge)‐based devices are recognized as one of the most promising next‐generation technologies for extending Moore's law. However, one of the critical issues is Fermi‐level pinning (FLP) at the metal/n‐Ge interface, and the resulting large contact resistance seriously degrades their performance. The insertion of a thin layer is one main technique for FLP modulation; however, the contact resistance...

Being direct wide bandgap, III‐nitride (III‐N) semiconductors have many applications in optoelectronics, including light‐emitting diodes, lasers, detectors, photocatalysis, etc. Incorporation of III‐N semiconductors with high‐efficiency optical resonances including surface plasmons, distributed Bragg reflectors and micro cavities, has attracted considerable interests for upgrading their performance,...
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...
Decentralized electrosynthesis of hydrogen peroxide (H2O2) via oxygen reduction reaction (ORR) can enable applications in disinfection control, pulping and textile bleaching, wastewater treatment, and renewable energy storage. Transition metal oxides are usually not efficient catalysts because they are more selective to produce H2O. Here, it is shown that divalent 3d transition metal cations (Mn,...
To address the dendrite growth and interface instability of high‐capacity Li metal anode, heterogeneous seed‐decorated 3D host materials are expected to suppress the growth of Li dendrites.
