Efficient electrocatalysts capable of operating continuously at industrial ampere‐level current densities are crucial for large‐scale applications of electrocatalytic water decomposition for hydrogen production. However, long‐term industrial overall water splitting using a single electrocatalyst remains a major challenge. Here, bimetallic polyphthalocyanine (FeCoPPc)‐anchored Ru nanoclusters, an innovative...
The typical chalcopyrite AgGaQ2 (Q = S, Se) are commercial infrared (IR) second‐order nonlinear optical (NLO) materials; however, they suffer from unexpected laser‐induced damage thresholds (LIDTs) primairy due to their narrow band gaps. Herein, what sets this apart from previously reported chemical substitutions is the utilization of an unusual cationic substitution strategy, represented by [[SZn...
Chalcohalides not only keep the balance between the nonlinear optical (NLO) coefficient and wide band gap, but also provide a promising solution to achieve sufficient birefringence for phase‐matching ability in NLO crystals. In this study, a novel chalcohalide, Cs4Zn5P6S18I2 (1) is successfully synthesized, by incorporating the highly electropositive Cs and the large electronegative I element into...
Cations that can regulate the configuration of anion group are greatly important but regularly unheeded. Herein, the structural transformation from 2D CS to 3D noncentrosymmetric (NCS, which is the prerequisite for second‐order NLO effect) is rationally designed to newly afford two sulfides LiMGa8S14 (M = Rb/Ba, 1; Cs/Ba, 2) by introducing the smallest alkali metal Li+ cation into the interlamination...
Ultrathin 2D porous carbon‐based materials offer numerous fascinating electrical, catalytic, and mechanical properties, which hold great promise in various applications. However, it remains a formidable challenge to fabricate these materials with tunable morphology and composition by a simple synthesis strategy. Here, a facile one‐step self‐flowering method without purification and harsh conditions...
Lattice strain modulation and vacancy engineering are both effective approaches to control the catalytic properties of heterogeneous catalysts. Here, Co@CoO heterointerface catalysts are prepared via the controlled reduction of CoO nanosheets. The experimental quantifications of lattice strain and oxygen vacancy concentration on CoO, as well as the charge transfer across the Co–CoO interface are all...
Using the MoS2‐WTe2 heterostructure as a model system combined with electrochemical microreactors and density function theory calculations, it is shown that heterostructured contacts enhance the hydrogen evolution reaction (HER) activity of monolayer MoS2. Two possible mechanisms are suggested to explain this enhancement: efficient charge injection through large‐area heterojunctions between MoS2 and...
A major challenge in siRNA vectors is developing approaches that ensure that when administered in vivo, the vectors can target their requisite site of action. This study reports a third type of nanoworm, biomimetic nanoerythrocytes for siRNA delivery, except for filomicelle and nanoworm iron‐oxide particle, which is the first approach that allows for targeted siRNA delivery by a process involving...
Red blood cell (RBC) membrane‐cloaked nanoparticles, reserving the intact cell membrane structure and membrane protein, can gain excellent cell‐specific functions such as long blood circulation and immune escape, providing a promising therapy nanoplatform for drug delivery. Herein, a novel RBC membrane biomimetic combination therapeutic system with tumor targeting ability is constructed by embedding...
Despite successful demonstration of linear polyethyleneimine (lPEI) as an effective carrier for a wide range of gene medicine, including DNA plasmids, small interfering RNAs, mRNAs, etc., and continuous improvement of the physical properties and biological performance of the polyelectrolyte complex nanoparticles prepared from lPEI and nucleic acids, there still exist major challenges to produce these...
On page 6214, H.‐Q. Mao and co‐workers present a flash nanocomplexation (FNC) method that offers high versatility for preparing various polyelectrolyte nanoparticles in a scalable process with high efficiency and reproducibility. The cover image depicts the rapid and homogenous mixing of DNA plasmid and lPEI solutions within a confined impinging jet device, producing DNA/lPEI nanoparticles with narrow...
