Hard carbons (HCs) are extensively investigated as the potential anodes for commercialization of sodium‐ion batteries (SIBs). However, the practical deployment of HC anode suffers from the retarded Na+ diffusion at the high‐rate or low‐temperature operation scenarios. Herein, a multiscale modification strategy by tuning HC microstructure on the particle level as well as replenishing extra Na+ reservoir...
Deformation twinning merits attention because of its intrinsic importance as a mode of energy dissipation in solids. Herein, through the atomistic electron microscopy observations, the size‐dependent twinning mechanisms in refractory body‐centered cubic molybdenum nanocrystals (NCs) under tensile loading are shown. Two distinct twinning mechanisms involving the nucleation of coherent and inclined...
The combination of photodynamic therapy (PDT) and chemotherapy (chemo‐photodynamic therapy) for enhancing cancer therapeutic efficiency has attracted tremendous attention in the recent years. However, limitations, such as low local concentration, non‐suitable treatment light source, and uncontrollable release of therapeutic agents, result in reduced combined treatment efficacy. This study considered...
Carrier‐Free ATP‐Activated Nanoparticles
In article number 2205825, Wen Sun and co‐workers develop ingenious adenosine triphosphate (ATP)‐activated nanoparticles (CDNPs) that are directly self‐assembled from photosensitizer (Cy‐I) and amphiphilic Cd(II) complex (DPA‐Cd). In cancer cells, CDNPs are disintegrated by ATP to release Cy‐I for generating single oxygen under 808 nm light and DPA‐Cd concurrently...
Understanding the direct interaction of nanostructures per se with biological systems is important for biomedical applications. However, whether nanostructures regulate biological systems by targeting specific cellular proteins remains largely unknown. In the present work, self‐assembling nanomicelles are constructed using small‐molecule oleanolic acid (OA) as a molecular template. Unexpectedly, without...
Cancer Cell Pyroptosis
In article number 2205531, Ke‐Wu Zeng and co‐workers describe the natural product oleanolic acid‐based self‐assembling nanostructures specially bind to proteasome subunit alpha 6 (PSMA6) to activate proteasome for cancer cell pyroptosis. This study opens up a new direction for the development anti‐cancer nanomedicine from natural resources.
Sodium‐ion batteries (SIBs) have been recognized as the promising alternatives to lithium‐ion batteries for large‐scale applications owing to their abundant sodium resource. Currently, one significant challenge for SIBs is to explore feasible anodes with high specific capacity and reversible pulverization‐free Na+ insertion/extraction. Herein, a facile co‐engineering on polymorph phases and cavity...
Gd chelates have occupied most of the market of magnetic resonance imaging (MRI) contrast agents for decades. However, there have been some problems (nephrotoxicity, non‐specificity, and low r1) that limit their applications. Herein, a wet‐chemical method is proposed for facile synthesis of poly(acrylic acid) (PAA) stabilized exceedingly small gadolinium oxide nanoparticles (ES‐GON‐PAA) with an excellent...
The emergence of metal–organic frameworks (MOFs) has sparked intensive attention and opened up the possibility of “crystal engineering.” However, low conductivity, slow diffusion of guest molecules, as well as powder forms always hinder the development of MOF application, especially for biosensors and bioelectronics. Herein, a coffee ring–inspired strategy toward oriented self‐assembly of a biomimetic...
Recent studies indicate that changing the physical properties of lipid bilayers may profoundly change the function of membrane proteins. Here, the effects of dissolved nitrogen and oxygen molecules on the mechanical properties and stability of lipid bilayers are investigated using differential confocal microscopy, atomic force microscopy, and molecular dynamics simulations. All experiments evidence...
Moore's law predicts the performance of integrated circuit doubles every two years, lasting for more than five decades. However, the improvements of the performance of energy density in batteries lag far behind that. In addition, the poor flexibility, insufficient‐energy density, and complexity of incorporation into wearable electronics remain considerable challenges for current battery technology...
MnO as anode materials has received particular interest owing to its high specific capacity, abundant resources, and low cost. However, serious problems related to the large volume change (>170%) during the lithiation/delithiation processes still results in poor rate capability and fast capacity decay. With homogenous crystals of MnO grown in the network of carbon nanofibers (CNF), binding effect...
