Severe nonradiative recombination and open‐circuit voltage loss triggered by high‐density interface defects greatly restrict the continuous improvement of Sn‐based perovskite solar cells (Sn‐PVSCs). Herein, a novel amphoteric semiconductor, O‐pivaloylhydroxylammonium trifluoromethanesulfonate (PHAAT), is developed to manage interface defects and carrier dynamics of Sn‐PVSCs. The amphiphilic ionic...
Transition metal ions are served as disinfectant thousand years ago. However, the in vivo antibacterial application of metal ions is strongly restricted due to its high affinity with proteins and lack of appropriate bacterial targeting method. Herein, for the first time, Zn2+‐gallic acid nanoflowers (ZGNFs) are synthesized by a facile one‐pot method without additional stabilizing agents. ZGNFs are...
The electrocatalytic nitrogen reduction reaction (NRR) is a promising approach for renewable ammonia synthesis but remains significantly challenging due to the low yield and poor selectivity. Herein, a facile N and S dual anions substitution strategy is developed to tune the Ti oxidation states of TiO2 nanohybrid catalyst (NS‐TiO2/C), in which anatase TiO2 nanoplates with dense Ti3+ active sites are...
Bi2Te3‐related alloys dominate the commercial thermoelectric market, but the layered crystal structure leads to the dissociation and intrinsic brittle fracture, especially for single crystals that may worsen the practical efficiency. In this work, point defect configuration by S/Te/I defects engineering is engaged to boost thermoelectric and mechanical properties of n‐type Bi2Te3 alloy, which, coupled...
The slow redox kinetics during cycling process and the serious shuttle effect caused by the solubility of lithium polysulfides (LiPSs) dramatically hinder the practical application of Li‐S batteries. Herein, a facile and scalable spray‐drying strategy is presented to construct conductive polar Mo2C quantum dots‐decorated carbon nanotube (CNT) networks (MCN) as an efficient absorbent and electrocatalyst...
Ferumoxytol capped anti PD‐L1 antibodies (aPD‐L1) loaded ultra‐large pore mesoporous silica nanoparticles (Fer‐ICB‐UPMSNPs) are delivered with image guidance after cabazitaxel (Cbz) chemotherapy for the treatment of prostate cancer. Sustained release of ICB from UPMSNP inhibits the immunosuppressive tumor microenvironment and activates tumor specific dendritic cells (DC). Activated antigen presenting...
Herein, ferumoxytol (Fer) capped antiprogrammed cell death‐ligand 1 (PD‐L1) antibodies (aPD‐L1) loaded ultralarge pore mesoporous silica nanoparticles (Fer‐ICB‐UPMSNPs) are formulated for a sequential magnetic resonance (MR) image guided local immunotherapy after cabazitaxel (Cbz) chemotherapy for the treatment of prostate cancer (PC). The highly porous framework of UPMSNP provides a large capacity...
Rapid sequestration and prolonged retention of intravenously injected nanoparticles by the liver and spleen (reticuloendothelial system (RES)) presents a major barrier to effective delivery to the target site and hampers clinical translation of nanomedicine. Inspired by biological macromolecular drugs, synthesis of ultrasmall (diameter ≈12–15 nm) porous silica nanoparticles (UPSNs), capable of prolonged...
It is still challenging to develop high‐efficiency and low‐cost non‐noble metal‐based electrocatalysts for hydrogen evolution reaction (HER) in pH‐universal electrolytes. Herein, hierarchically porous W‐doped CoP nanoflake arrays on carbon cloth (W‐CoP NAs/CC) are synthesized via facile liquid‐phase reactions and a subsequent phosphorization process. The W‐CoP NAs/CC hybrid can be directly employed...
Significantly enhanced thermoelectric performance is achieved for eco‐friendly SnTe by a coorperative effect between a dopant resonant energy level and interstitial defects. By manipulating the band structure through indium doping, the Seebeck coefficient is remarkably improved, leading to an enhanced power factor, with a high level of ≈29 µW cm−1 K−2 at 873 K. Lattice thermal conductivity is sharply...
Enrichment of molecular photosensitizers and catalysts in a confined nanospace is conducive for photocatalytic reactions due to improved photoexcited electron transfer from photosensitizers to catalysts. Herein, the self‐assembly of a highly stable 3D supramolecular organic framework from a rigid bipyridine‐derived tetrahedral monomer and cucurbit[8]uril in water, and its efficient and simultaneous...
