Improving the precise accumulation and retention of nanomedicines in tumor cells is one of the keys to effective therapy of tumors. Herein, supramolecular peptides capped Au nanocages (AuNCs) that may self‐aggregate into micron‐sized clusters intracellularly in response to spermine (SPM), leading to specific accumulation and retention of AuNCs in SPM‐overexpressed tumor cells, are developed. In this...
Magnesium‐ion batteries (MIB) have gradually attracted attention owing to their high theoretical capacity, high safety, and low cost. A bimetallic metal–organic framework self‐sacrificing template and a co‐assembly strategy are used to prepare a high‐performance, stable cycling NiSe2‐CoSe2@TiVCTx (NCSe@TiVC) heterostructure MIB cathode that can be used as a flexible integrated unit to power future...
The structure–activity relationship is a cornerstone topic in catalysis, which lays the foundation for the design and functionalization of catalytic materials. Of particular interest is the catalysis of the hydrogen evolution reaction (HER) by palladium (Pd), which is envisioned to play a major role in realizing a hydrogen‐based economy. Interestingly, experimentalists observed excess heat generation...
Selective induction of tumor thrombus infarction is a promising antitumor strategy. Non‐persistent embolism due to non‐compacted thrombus and activated fibrinolytic system within the tumor large blood vessels and tumor margin recurrence are the main therapeutic bottlenecks. Herein, an erythrocyte membrane‐coated invisible acoustic‐sensitive nanoparticle (TXA+DOX/PFH/RBCM@cRGD) is described, which...
Developing dynamic and highly sensitive methods for imaging M2‐type tumor‐associated macrophages (TAMs) is vital for monitoring the tumor progression and assessing the therapeutic efficacy. Here, the fabrication and application of rationally designed Er‐based rare‐earth nanoprobes for the targeted imaging of M2‐type TAMs in glioblastoma (GBM) through the second near‐infrared (NIR‐II) fluorescence...
Porous electrodes that conduct electrons, protons, and oxygen ions with dramatically expanded catalytic active sites can replace conventional electrodes with sluggish kinetics in protonic ceramic electrochemical cells. In this work, a strategy is utilized to promote triple conduction by facilitating proton conduction in praseodymium cobaltite perovskite through engineering non‐equivalent B‐site Ni/Co...
Noncentrosymmetric Oxides
In article number 2200992, Yannick Mugnier and co‐workers critically review the solution‐based synthesis methods for the preparation of noncentrosymmetric oxide nanocrystals with perovskite and non‐perovskite crystalline structures. Special attention of the research community to the detailed understanding of their formation mechanisms is still needed for improving their resulting...
Although asymmetric supercapacitors (ASCs) can achieve high energy density, the lifespan and power density are severely suppressed due to the low conductivity of using pseudocapacitive or battery‐type electrode materials. Recently, nonporous conductive coordination polymers (c‐CPs) have sparked interests in supercapacitors. However, their performance is expected to be limited by the nonporous features,...
Bone repair in real time is a challenging medical issue for elderly patients; this is mainly because aged bone marrow mesenchymal stem cells (BMSCs) possess limited osteogenesis potential and repair capacity. In this study, triboelectric stimulation technology is used to achieve bone repair via mechanosensation of Piezo1 by fabricating a wearable pulsed triboelectric nanogenerator (WP‐TENG) driven...
The rate‐determining step of the oxygen evolution reaction based on a semiconductor photoanode is the formation of the OO bond. Herein, polyethylene glycol (PEG)‐modified BiVO4 photoanodes are reported, in which protons can be transferred quickly due to the high proton conductivity of PEG, resulting in the acceleration of the OO bond formation rate. These are fully demonstrated by different kinetic...
Plants are anatomically and physiologically different from humans and animals; however, there are several possibilities to utilize the unique structures and physiological systems of plants and adapt them to new emerging technologies through a strategic biomimetic approach. Moreover, plants provide safe and sustainable results that can potentially solve the problem of mass‐producing practical materials...
In this work, electrocatalytic upgrade of n‐valeraldehyde to octane with higher activity and selectivity is achieved over Au single‐atom catalysts (SACs)–NiMn2O4 spinel synergetic composites. Experiments combined with density functional theory calculation collaboratively demonstrate that Au single‐atoms occupy surface Ni2+ vacancies of NiMn2O4, which play a dominant role in n‐valeraldehyde selective...
Fe‐N‐C single‐atom catalysts (SACs) are emerging as a promising class of electrocatalysts for the oxygen reduction reaction (ORR) to replace Pt‐based catalysts. However, due to the limited loading of Fe for SACs and the inaccessibility of internal active sites, only a small portion of the sites near the external surface are able to contribute to the ORR activity. Here, this work reports a metal–organic...
Aqueous Zn metal batteries (AZMBs) have been considered as a promising alternative to the existing Li‐ion batteries. Nevertheless, the large‐scale application of the AZMBs is restricted by the dendrite formation and side reactions within the Zn metal anodes (ZMAs) during cycling. Herein, an atomically dispersed Cu in leaf‐like Zn‐coordinated zeolitic imidazolate framework (ZIF‐L) nanoflakes on Ti...
Carbon materials, as promising anode candidates for K+ storage due to their low cost, abundant sources, and high physicochemical stability, however, encounter limited specific capacity and unfavorable cycling stability that seriously hinder their practical applications. Herein, a feasible strategy to tailor and stabilize the nitrogen species in unique P/N co‐doped disk‐like carbon through the Sn incorporation...
Ongoing efforts to design novel materials with efficient structure‐property‐performance relations prove challenging. Core‐shell structures have emerged as novel materials with controlled production routes and highly tailorable properties that offer extensive advantages in advanced oxidation processing, particularly in photocatalysis and photoelectrochemical applications. WO3, which is an optoelectronically...
Biomaterials with outstanding mechanical properties, including spider silk, wood, and cartilage, often feature an oriented nanofibrillar structure. The orientation of nanofibrils gives rise to a significant mechanical anisotropy, which is extremely challenging to characterize, especially for microscopically small or inhomogeneous samples. Here, a technique utilizing atomic force microscope indentation...
