The lithium–oxygen (Li–O2) battery with high energy density of 3860 Wh kg−1 represents one of the most promising new secondary batteries for future electric vehicles and mobile electronic devices. However, slow oxygen reduction/oxygen evolution (ORR/OER) reaction efficiency and unstable cycling performance restrain the practical applications of the Li–O2 battery. Herein, Ru‐modified nitrogen‐doped...
The mechanism of extracellular ligand nano‐geometry in ex vivo T cell activation for immunotherapy remains elusive. Herein, the authors demonstrate large aspect ratio (AR) of gold nanorods (AuNRs) conjugated on cell culture substrate enhancing both murine and human T cell activation through the nanoscale anisotropic presentation of stimulatory ligands (anti‐CD3(αCD3) and anti‐CD28(αCD28) antibodies)...
High‐capacity Ni‐rich layered oxides are considered as promising cathodes for lithium‐ion batteries. However, the practical applications of LiNi0.83Co0.07Mn0.1O2 (NCM83) cathode are challenged by continuous transition metal (TM) dissolution, microcracks and mixed arrangement of nickel and lithium sites, which are usually induced by deleterious cathode–electrolyte reactions. Herein, it is reported...
The design of porous structure in wearable sensors is very important for the detection of mechanical signals. However, it remains challenging to construct a porous structure capable of detecting all kinds of mechanical signals. Here, round wire with long‐range orientated micropores (RW‐LOM) is fabricated by a newly established freeze printing technique and constructed into a wearable sensor by the...
Magnetic photonic crystals (PCs) possess attractive magnetic orientation, flexible pattern designability, and abundant angle‐dependent colors, providing immense potential in anticounterfeiting field. However, all‐solid magnetic PCs‐based labels generally suffer from incompatibility with screen printing techniques, and inferior environmental endurance and mechanical properties. Herein, by developing...
The surgical removal of lesions is among the most common and effective treatments for atherosclerosis. It is often the only curative treatment option, and the ability to visualize the full extent of atherosclerotic plaque during the operation has major implications for the therapeutic outcome. Fluorescence imaging is a promising approach for the inspection of atherosclerotic plaques during surgery...
Conductive hydrogels can be prepared by incorporating various conductive materials into polymeric network hydrogels. In recent years, conductive hydrogels have been developed and applied in the field of strain sensors owing to their unique properties, such as electrical conductivity, mechanical properties, self‐healing, and anti‐freezing properties. These remarkable properties allow conductive hydrogel‐based...
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,...
Monolithic integration of nanostructured metalenses with broadband light transmission and good charge transport can simultaneously enhance the sensitivity, speed, and efficiency of photodetectors. The realization of built‐in broadband metalenses in perovskite photodetectors, however, has been largely challenged by the limited choice of materials and the difficulty in nanofabrication. Here a new type...
Mitochondrial dysfunction is considered to be an important factor that leads to aging and premature aging diseases. Transferring mitochondria to cells is an emerging and promising technique for the therapy of mitochondrial deoxyribonucleic acid (mtDNA)‐related diseases. This paper presents a unique method of controlling the quality and quantity of mitochondria transferred to single cells using an...
Mitochondrial Transfer
In article number 2103086, Gang Li, Dong Sun, and co‐workers present a novel method of controlling the quality and quantity of mitochondria transferred to single cells using an automated optical tweezer‐based micromanipulation system. The transfer of isolated mitochondria from fetal mesenchymal stem cells (fMSCs) to adult mesenchymal stem cells (aMSCs) by the developed system...
Managing elastic properties of ABX3 type molecular perovskite ferroelectrics is critical to their future applications since these parameters determine their service durability and reliability in devices. The abundant structural and chemical viability of these compounds offer a convenient way to manipulate their elastic properties through a facile chemical approach. Here, the elastic properties and...

The combined features of silicon and layered structure bridge the 2D materials family and silicon‐based materials family together, while the intrinsic defects in Si2Te3 yield ultrawide photoluminescence spectra and broadband spectral response...
Silicon‐based semiconductor materials dominate modern technology for more than half a century with extraordinary electrical‐optical performance and mutual processing compatibility. Now, 2D materials have rapidly established themselves as prospective candidates for the next‐generation semiconductor industry because of their novel properties. Considering chemical and processing compatibility, silicon‐based...
The crystalline orientation and phase distribution are two important parameters for high‐performance 2D perovskite solar cells. Therefore, it is essential to understand how the structure of spacer ligands influences the orientation and phase distribution of resulting 2D perovskite films. In this work, a new member of Dion–Jacobson (DJ) phase 2D perovskites based on trans‐1,4‐cyclohexanediamine (CHDA)...
Targeted and sustained delivery of drugs to diseased tissues/organs, where body fluid exchange and catabolic activity are substantial, is challenging due to the fast cleansing and degradation of the drugs by these harsh environmental factors. Herein, a multifunctional and bioadhesive polycaprolactone‐β‐cyclodextrin (PCL‐CD) polymersome is developed for localized and sustained co‐delivery of hydrophilic...
