Processing transition metal carbides/nitrides (MXenes) inks into large‐area functional coatings expects promising potential for electromagnetic interference (EMI) shielding and infrared stealth. However, the coating performances, especially for scalable fabrication techniques, are greatly constrained by the flake size and stacking manner of MXene. Herein, the large‐area production of highly densified...
Bi2O3/rare earth oxide biphasic absorbers are attractive for high‐efficiency X‐ray shielding due to the complementary X‐ray absorption effects. However, its application is severely hindered by poor interphasic contact. Here, a new Janus interface engineering strategy is reported for the construction of continuous and flexible Bi2O3/Gd2O3 crystal nanofibrous membranes (FJNMs) with micro/nano dual self‐strengthening...
The pathological aggregation of some proteins is claimed to be highly related to several human diseases, such as β‐amyloid 1–42 (Aβ42) to Alzheimer's disease (AD), islet amyloid polypeptide, and insulin to type 2 diabetes mellitus. Therefore, it is in desperate need to develop effective methods for detection of protein aggregates and inhibition of abnormal aggregation. Herein, to construct all‐in‐one...
P‐block metals have gradually been utilized to synthesize non‐noble‐metal catalysts for oxygen reduction reaction (ORR) due to the easily tunable localized p‐orbitals and resulted versatile electronic structures. The high‐density single‐atom bismuth sites (Bi−NC) anchored onto nitrogen‐doped three‐dimensional porous carbon are proved to possess significant electrocatalytic ORR performance. Theoretical...
Vacuum vapor deposition (VVD) is a promising way to advancing the commercialization of perovskite light sources owing to its convenience for wafer‐scale mass production and compatibility with silicon photonics manufacturing infrastructure. However, the light emission performance of VVD‐grown perovskites still lags far behind that of the conventional solution‐processed counterparts due to their inferior...
Antibacterial Effects
In article number 2200548, Xu Yu, Li Xu, Itamar Willner, and co‐workers show that the Au3+‐metal‐organic framework nanoparticles (NMOFs) nanozymes reveal dual oxidase‐like and peroxidase‐like activities and act as an active catalyst for the catalyzed generation of O2•− under aerobic conditions or •OH in the presence of H2O2. The two reactive oxygen species agents cooperatively...
The synthesis and characterization of Au3+‐modified UiO‐67 metal‐organic framework nanoparticles, Au3+‐NMOFs, are described. The Au3+‐NMOFs reveal dual oxidase‐like and peroxidase‐like activities and act as an active catalyst for the catalyzed generation of O2•− under aerobic conditions or •OH in the presence of H2O2. The two reactive oxygen species (ROS) agents O2•− and •OH are cooperatively formed...
Herein, a highly stable aggregation‐induced emission (AIE) fluorescent nanodot assembled by an amphiphilic quinoxalinone derivative‐peptide conjugate, namely Quino‐1‐Fmoc‐RACR (also termed as Q1‐PEP), which exhibits large Stokes shift and an endoplasmic reticulum (ER)‐targeting capacity for bioimaging is reported. It is found that the resulting nanodot can effectively enter the ER with high fluorescent...
Collecting circulating tumor cells (CTCs) shed from solid tumor through a minimally invasive approach provides an opportunity to solve a long‐standing oncology problem, the real‐time monitoring of tumor state and analysis of tumor heterogeneity. However, efficient capture and detection of CTCs with diverse phenotypes is still challenging. In this work, a microfluidic assay is developed using the rationally‐designed...
