Perovskite Oxide‐Based Electrocatalysts
In article number 2101605, Shi Chen, Shuangpeng Wang, Guichuan Xing, Hui Pan, and co‐workers systematically summarize perovskite oxides as electrocatalysts for efficient oxygen evolution reaction (OER). The catalytic mechanism and descriptors for perovskite oxides are also discussed in detail. Additionally, various strategies to improve the OER catalytic performance...
2D metal‐halide perovskites have attracted intense research interest due to superior long‐term stability under ambient environments. Compared to their 3D analog, the alternate arrangement of organic and inorganic layers leads to forming a multilayer quantum well (MQW), which endows 2D perovskites with anisotropic optoelectronic properties. In addition, the spacer layer functions as a hydrophobic barrier...
As a sustainable and clean water production technology, solar thermal water evaporation has been extensively studied in the past few years. One challenge is that upon operation, salt would form on surface of the solar absorbers leading to inefficient water supply and light absorption and thus much reduced water vaporization rate. To address this problem, a simple solar evaporator based on an array...
Tumor‐Targeting Nanozymes
In article number 2102624, Qi Zhao and co‐workers demonstrate that a nanozyme‐mediated photothermal‐nanocatalytic effect disrupts the tumor extracellular matrix and induces cancer cell death. The alterations in the tumor microenvironment ultimately promote tumor infiltration and immune response of CAR T cells against solid tumors.
Polymeric nanocarriers have high biocompatibility for potential drug delivery applications. After entering bloodstream, nanocarriers will circulate, interact with proteins, dissociate, or be cleared by reticuloendothelial system. Zebrafish as a visual animal model, can serve as a tool for screening nanomedicines and monitoring nanocarrier behaviors in vivo. However, a comprehensive correlation between...
Conjugated polymers (CPs) are capable of coordinating the electron coupling phenomenon to bestow powerful optoelectronic features. The light‐harvesting and light‐amplifying properties of CPs are extensively used in figuring out the biomedical issues with special emphasis on accurate diagnosis, effective treatment, and precise theranostics. This review summarizes the recent progress of CP materials...
Targeting B7‐H3 chimeric antigen receptor (CAR) T cells has antitumor potential for therapy of non‐small cell lung cancer (NSCLC) in preclinical studies. However, CAR T cell therapy remains a formidable challenge for the treatment of solid tumors due to the heterogeneous and immunosuppressive tumor microenvironment (TME). Nanozymes exhibit merits modulating the immunosuppression of the tumor milieu...
As one of the most efficient electrochemical energy storage devices, the energy density of lithium‐ion batteries (LIBs) has been extensively improved in the past several decades. However, with increased energy density, the safety risk of LIBs becomes higher too. The frequently occurred battery accidents worldwide remind us that safeness is a crucial requirement for LIBs, especially in environments...
The precise accumulation and extended retention of nanomedicines in the tumor tissue has been highly desired for cancer therapy. Here a novel supramolecular‐peptide derived nanodrug (SPN) that can be transformed to microfibers in response to intracellular polyamine in cancer cells for significantly enhanced tumor specific accumulation and retention is developed. The supramolecular‐peptide is constructed...
Potassium‐ion batteries (PIBs) are recognized as promising alternatives for lithium‐ion batteries as the next‐generation energy storage systems. However, the larger radius of K+ hinders the K+ insertion into the conventional carbon electrode and results in sluggish potassiation kinetics and poor cycling stability. Here, nitrogen and fluorine dual doping of soft carbon nanotubes (NFSC) anode are synthesized...
Organic photodetectors (OPDs), which usually work as photodiodes, photoconductors, or phototransistors, have emerged as candidates for next‐generation light sensing. However, low response speed caused by low carrier mobility and resistance‐capacitance (RC) time constant, severely hinders the commercialization of OPDs. Herein, the authors demonstrate a state‐of‐the‐art OPD with a record response speed...
Nanomedicine integrates different functional materials to realize the customization of carriers, aiming at increasing the cancer therapeutic efficacy and reducing the off‐target toxicity. However, efforts on developing new drug carriers that combine precise diagnosis and accurate treatment have met challenges of uneasy synthesis, poor stability, difficult metabolism, and high cytotoxicity. Metal‐phenolic...
