In article number 2100101, Maning Liu, Paola Vivo, and co‐workers report that manganese (Mn) doping of bismuth‐based perovskite nanocrystals (Cs3Bi2I9) promotes their synthesis to obtain a high phase purity of the host nanocrystals. The valence band of the host nanocrystals is deepened by the increase of Mn‐doping concentration, resulting in an enhanced open‐circuit voltage and a prolonged electron...
In article number 2100040, Youngho Shin, Sangkee Min, and co‐workers present core–multishell cathode materials with longer cycle life, improved rate performance, enhanced thermal stability, and low impedance growth. The mechanical properties of these core–multishell cathode materials are statistically investigated by picoindentation.
In article number 2100315, Hong Xu and co‐workers develop a huge barcode library containing 300 kinds of encoded microbeads through a novel structure‐fluorescence combinational strategy. These barcodes similar to celestial bodies in the starry sky could be excited by a single laser to achieve the decoding of three elements, including structure and two fluorescence information. The barcodes platform...
The nitride films with high indium (In) composition play a crucial role in the fabrication of In‐rich InGaN‐based optoelectronic devices. However, a major limitation is In incorporation requiring a low temperature during growth at the expense of nitride dissociation. Here, to overcome this limitation, a strain‐modulated growth method, namely the graphene (Gr)‐nanorod (NR) enhanced quasi‐van der Waals...
Highly flexible and porous metallic papers with bulk metallic conductivity and large surface areas are prepared using a metal nanoparticle (NP) assembly‐induced electroplating approach by Seung Woo Lee, Jinhan Cho, and co‐workers in article number 2007579. High‐energy pseudocapacitive NPs and conductive metal NPs are also layer‐by‐layer‐assembled onto the 3D porous metallic paper, which significantly...
Ovarian cancer is an aggressive tumor owing to its ability to metastasize from stage II onward. Herein, lipid nanoparticles (LNPs) that encapsulate combination of small interfering RNAs (siRNAs), polo‐like kinase‐1 (PLK1), and eukaryotic translation‐initiation factor 3c (eIF3c), to target different cellular pathways essential for ovarian cancer progression are generated. The LNPs are further modified...
With the rapid development of suspension array technology, microbeads‐based barcodes as the core element with sufficient encoding capacity are urgently required for high‐throughput multiplexed detection. Here, a novel structure‐fluorescence combinational encoding strategy is proposed for the first time to establish a barcode library with ultrahigh encoding capacities. Based on the never revealed transformability...
3D carbon‐based materials with multiscale hierarchy are promising electrode materials for electrochemical energy storage and conversion applications, but the synthesis in an efficient and large‐scale way is still a great challenge. Herein, a carbon nanorod‐assembled 3D superstructure is facilely fabricated by morphology‐preserving conversion of a metal–organic framework (MOF) nanorod‐assembled superstructure...
The doping of halide perovskite nanocrystals (NCs) with manganese cations (Mn2+) has recently enabled enhanced stability, novel optical properties, and modulated charge carrier dynamics of the NCs host. However, the influence of Mn doping on the synthetic routes and the band structures of the host has not yet been elucidated. Herein, it is demonstrated that Mn doping promotes a facile, safe, and low‐hazard...
Lipid nanoparticles encapsulating two different small interfering ribonucleic acids are developed that block essential pathways for cancer cell survival. Targeting of metastasized ovarian cancer cells is further enhanced by coating nanoparticles with hyaluronan. Robust gene silencing in key tissues involved in ovarian cancer pathophysiology in an advanced ovarian cancer mouse model and improved median...
Zinc‐ion storage is a promising electrochemical energy field due to loads of its advantages like easy preparation, environmental friendliness, high safety performance, and high capacity. Carbon materials have been widely studied for zinc‐ion storage due to their extraordinary properties such as earth‐abundancy, low‐cost, good electrical conductivity, various structures, and good stability. This article...
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...
Natural materials, such as silk, nacre, and bone, possess superior mechanical properties which are derived from their unique hierarchical structures. Individual carbon nanotubes (CNTs) are considered as one of the strongest materials. However, macroscopic CNT fibers usually have breaking strength far below that of individual CNTs. In this work, by mimicking the structure of natural silk fibers, strong...
Fischer‐Tropsch synthesis (FTS) is an effective route to produce olefins, gasoline, diesel, and oxygenates from syngas (CO + H2). However, it still remains a challenge for regulating the product distribution of FTS. Here, a series of Co/C sub‐microreactors with precise designed nanoarchitectures are synthesized for selective syngas conversion. Through a combination of surface protection‐assisted etching...
A central issue in protein electronics is how far the structural stability of the protein is preserved under the very high electrical field that it will experience once a bias voltage is applied. This question is studied on the redox protein Azurin in the solid‐state Au/protein/Au junction by monitoring protein vibrations during current transport under applied bias, up to ≈1 GV m−1, by electrical...
Ni‐rich cathode materials provide high energy density, but their structural and surface instability limits their cyclability and thermal stability. As one of the approaches to mitigate this problem, cathode materials comprising Ni‐rich high‐capacity core wrapped in Mn‐rich multiple shells are produced successfully. In contrast to the conventional batch‐type process for concentration‐gradient materials,...

The key factor for photodynamic therapy is highly efficient loading and protection of photosensitizers. Covalent organic framework is a new type of organic porous material with rich sources and has huge development potential in the loading of photosensitizers. However, the π–π interaction...
In this work, a novel lollipop nanostructure of Co3O4@MnO2 composite is prepared as anode material in lithium‐ion batteries (LIBs). Cobalt metal–organic framework (ZIF‐67) is grown on the open end of MnO2 nanotubes via a self‐assembly process. The obtained ZIF‐67@MnO2 is then converted to Co3O4@MnO2 by a simple annealing treatment in air. Scanning electron microscopy, transmission electron microscopy,...
