Synergistically coupled 1D/2D materials have great potential for energy conversion application due to its high catalytic activity. Herein, an in situ assembly strategy is developed for preparing the P, N co‐doped carbon nanotubes and Mo/MoS2(1−x−y)Px nanosheets composites (Mo/MoS2(1−x−y)Px@PNC) for hydrogen evolution reactions (HER). The PNC guarantees structural stability and fast charge transfer...
Lithium–sulfur (Li–S) batteries are facing a significant barrier due to the diffusion of intermediate redox species. Although some S doped covalent framework cathodes have been reported with outstanding reversibility, the low content of sulfur (less than 30%) limits the practical applications. To overcome the issue, the sulfur and nitrogen co‐doped covalent compounds (S‐NC) as a host‐type cathode...
Strengthening the interfacial interaction in heterogeneous catalysts can lead to a dramatic improvement in their performance and allow the use of smaller amounts of active noble metal, thus decreasing the cost without compromising their activity. In this work, a facile phase‐segregation method is demonstrated for synthesizing platinum–tin oxide hybrids supported on carbon black (PtSnO2/C) in situ...
Artificial cells are a powerful platform in the study of synthetic biology and other valuable fields. They share a great potential in defining and utilizing the superiority of the living system. Here, a protein synthesis system based on thermal responsive hydrogels with porous structure is reported. The hydrogels can immobilize plasmids on the surface inside their porous structure through a volume...
Non‐enveloped RNA viruses pervade all domains of life. In a cell, they co‐assemble from viral RNA and capsid proteins. Virus‐like particles can form in vitro where virtually any non‐cognate polyanionic cargo can be packaged. How only viral RNA gets selected for packaging in vivo, in presence of myriad other polyanionic species, has been a puzzle. Through a combination of charge detection mass spectrometry...
In vitro and ex vivo intracellular delivery methods hold the key for releasing the full potential of tissue engineering, drug development, and many other applications. In recent years, there has been significant progress in the design and implementation of intracellular delivery systems capable of delivery at the same scale as viral transfection and bulk electroporation but offering fewer adverse...
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...
Despite the progress achieved in nanomedicine during the last decade, the translation of new nanotechnology‐based therapeutic systems into clinical applications has been slow, especially due to the lack of robust preclinical tissue culture platforms able to mimic the in vivo conditions found in the human body and to predict the performance and biotoxicity of the developed nanomaterials. Organ‐on‐a‐chip...
Mesocrystals, consisting of small subunits, have gained research interests owing to their ability to simultaneously modify material‐specific properties and interactions among subunits. However, despite these unique characteristics, most mesocrystals are composed of a single material, and there is a disjunction between academic discovery and practical application. In this study, the synthesis of multi‐component...
Considerable efforts have been exerted to understand the formation and properties of the solid electrolyte interphase (SEI) in sodium ion batteries. However, the puzzling existence and role of SEI behind the huge volume changes of the graphite electrodes need to be answered. Herein, the reason of how ether‐derived SEI maintains excellent reversibility despite the huge volume changes during cycling...
The development of intricate and complex self‐assembling structures in the micrometer range, such as biomorphs, is a major challenge in materials science. Although complex structures can be obtained from self‐assembling materials as they segregate from solution, their size is usually in the nanometer range or requires accessory techniques. Previous studies with intrinsically disordered proteins (IDPs)...
In article number 2004696, Young Keun Kim and co‐workers present multi‐component mesocrystalline nanoparticles (MMNPs), consisting of magnetite, zinc ferrite, and zinc oxide nanocrystals as a magnetically recoverable photo‐catalyst for efficient wastewater purification system. The MMNPs show not only material‐dependent properties from unit nanocrystals, but also synergetic properties from the unique...
Exploring active, stable, and low‐cost bifunctional electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is crucial for water splitting technology associated with renewable energy storage in the form of hydrogen fuel. Here, a newly designed antiperovskite‐based hybrid composed of a conductive InNNi3 core and amorphous InNi(oxy)hydroxide shell is first reported...
In article number 2005191, José Carlos Rodríguez‐Cabello and co‐workers report micrometric colporate biomorphs self‐assembled from an intrinsically disordered silk‐elastin‐like protein, in which the concurrent effect of hydrophobic, electrostatic and H‐bonding interactions are capable of generating and kinetically trapping complex and transient structures in time during desolvation processes. This...
Nanocage‐shaped Co3−xZrxO4 solid‐solution supports and the corresponding platinum loaded nanocomposites, yPt/Co3−xZrxO4 (x =0.27, 0.50, 0.69; y = 0.5, 1.0, 2.0 wt.%), are successfully fabricated via a Cu2O nanocube hard template method and a glycol reduction method, respectively. The hollow nanocage structures obviously improve surface areas; moreover, the Zr doping forms the Co3−xZrxO4 solid‐solution...
Logic switches enabled by nanoelectromechanical systems (NEMS) offer abrupt on/off‐state transition with zero off‐state leakage and minimal subthreshold swing, making them uniquely suited for enhancing mainstream electronics in a range of applications, such as power gating, high‐temperature and high‐voltage logic, and ultralow‐power circuits requiring zero standby leakage. As NEMS switches are scaled...
Lead halide perovskite quantum dots (QDs) are promising materials for next‐generation photoelectric devices because of their low preparation costs and excellent optoelectronic properties.

Highly stretchable, conductive, biocompatible conductors, and connectors are crucial for the fabrication of flexible devices. However, it remains a problem to get highly stretchable, conductive materials with low cost on a large scale. Another problem in production is the connection between soft and rigid components. Here, a new conductive nanocomposite is reported by mixing the 11‐mercaptoundecanoic...
