Heterogeneous crystalline‐amorphous structures, with tunable electronic structures and morphology, hold immense promise as catalysts for lithium‐oxygen batteries (LOBs). Herein, a nanotube network constructed by crystalline nickel sulfide/amorphous nickel phosphate (NiS/NiPO) heterostructure is prepared on Ni foam through the sulfurization of the precursor generated hydrothermally. Used as cathodes,...
Carbon dots (CDs), a new type of carbon‐based fluorescent nanomaterial, have attracted widespread attention because of their numerous excellent properties. Lignocellulosic biomass is the most abundant renewable natural resource and possesses broad potential to manufacture different composite and smart materials. Numerous studies have explored the potential of using the components (such as cellulose,...
Amination of aryl chlorides by metallaphotocatalysis is highly desired but remains practically challenging. Meanwhile, relying on soluble noble‐metal photocatalysts suffers from resource scarcity and structural instability which limit their practical application. Here in, a highly crystalline acetylene‐based hydrazone‐linked covalent organic framewok‐1 (AC‐COF‐1) is reported that enables metallaphotocatalytic...
In vivo simultaneous visualization of multiple biomarkers is critical to accurately diagnose disease and decipher fundamental processes at a certain pathological evolution, which however is rarely exploited. Herein, a multimodal activatable imaging probe (P‐125I) is reported with activatable fluoro‐photoacoustic and radioactive signal for in vivo imaging of biomarkers (i.e., hepsin and prostate‐specific...
In this paper, the authors report the fabrication of a sensitive deep ultraviolet (DUV) photodetector by using an individual GaSe nanobelt with a thickness of 52.1 nm, which presents the highest photoresponse at 265 nm illumination with a responsivity and photoconductive gain of about 663 A W−1 and 3103 at a 3 V bias, respectively, comparable to or even better than other reported devices based on...
NIR‐Triggered Antibacterial Therapy
In article number 2102315, Xiaohua Yu, Zhaoming Ye, and co‐workers successfully transform the utility of iodine from external use to orthopedic implants leveraging the superior loading capacity of metal–organic frameworks. Such an immobilization approach skillfully bypasses the insolubility and vulnerability associated with iodine when turned for internal use. Under...
Iodine has been known as an effective disinfectant with broad‐spectrum antimicrobial potency yet without drug resistance risk when used in clinic. However, the exploration of iodine for antibacterial therapy in orthopedics remains sparse due to its volatile nature and poor solubility. Herein, leveraging the superior absorption capability of metal–organic frameworks (MOFs) and their inherent photocatalytic...
Aqueous Zn ion batteries (AZIBs), featuring low cost, long‐term cycling stability, and superior safety are promising for applications in advanced energy storage devices. However, they still suffer from unsatisfactory energy density and operating voltage, which are closely related to cathode materials used. Herein, the use of monoclinic MnV2O6 (MVO) is reported, which can be activated for high‐capacity...
Sodium metal anode, featuring high capacity, low voltage and earth abundance, is desirable for building advanced sodium‐metal batteries. However, Na‐ion deposition typically leads to morphological instability and notorious chemical reactivity between sodium and common electrolytes still limit its practical application. In this study, a porous BN nanofibers modified sodium metal (BN/Na) electrode is...
Controlled growth of high‐quality patterned perovskite films on a large scale is essentially required for the application of this class of materials in functional integrated devices and systems. Herein, graphene‐assisted hydrophilic–hydrophobic surface‐induced growth of Cs‐doped FAPbI3 perovskite films with well‐patterned shapes by a one‐step spin‐coating process is developed. Such a facile fabrication...
In drug delivery, the poor tumor perfusion results in disappointing therapeutic efficacy. Nanomedicines for photodynamic therapy (PDT) greatly need deep tumor penetration due to short lifespan and weak diffusion of the cytotoxic reactive oxygen species (ROS). The damage of only shallow cells can easily cause invasiveness and metastasis. Moreover, even if the nanomedicines enter into deeper lesion,...
Rapid clearance of nanoagents is a critical criterion for their clinical translation. Herein, it is reported that biodegradable and renal clearable nanoparticles are potentially useful for image‐guided photothermal therapy of tumors. The multifunctional nanoparticles with excellent colloidal stability are synthesized through coordination reactions between Fe3+ ions and gallic acid (GA)/polyvinyl pyrrolidone...
The performance for biomolecular detection is closely associated with the interfacial structure of a biosensor, which profoundly affects both thermodynamics and kinetics of the assembly, binding and signal transduction of biomolecules. Herein, it is reported on a one‐step and template‐free on‐electrode synthesis method for making shape‐controlled gold nanostructures on indium tin oxide substrates,...
