The portable power bank as an energy storage device has received tremendous attention while the limited capacity and periodical charging are critical issues. Here, a self‐charging power system (SCPS) consisting of a 0.94(Bi0.5Na0.5)TiO3–0.06Ba(Zr0.25Ti0.75)O3/polyvinylidenefluoride (BNT–BZT/PVDF) composite film‐based triboelectric nanogenerator (TENG) is designed as a wind energy harvester and an...
Facilitating the mass transfer and spatial charge separation is a great challenge for achieving efficient oxidation of NO and outstanding sulfur resistance. Herein, a hydrothermal‐assisted confinement growth technique is used to fabricate well‐defined three‐dimensional CuOx@MnOx hetero‐shelled hollow‐structure catalysts. By integrating the coupled plasma space reactor and the porous hierarchical structure...
Pancreatic ductal adenocarcinoma (PDAC) is one of the most malignant tumors with a low survival rate. The therapeutic effect of chemotherapy and immunotherapy for PDAC is disappointing due to the presence of dense tumor stroma and immunosuppressive cells in the tumor microenvironment (TME). Herein, a tumor‐penetrating nanoparticle is reported to modulate the deep microenvironment of PDAC for improved...
Schiff‐base networks (SBNs), as typical examples of nitrogen‐doped microporous organic polymers (MOPs), exhibit promising application prospects owing to their stable properties and tunable chemical structures. However, their band structure engineering, which plays a key role in optical properties, remains elusive due to the complicated mechanisms behind energy level adjustment. In this work, a series...
CO2 conversion into value‐added chemical fuels driven by solar energy is an intriguing approach to address the current and future demand of energy supply. Currently, most reported surface‐sensitized heterogeneous photocatalysts present poor activity and selectivity under visible light irradiation. Here, photosensitized porous metallic and magnetic 1200 CoC composites (PMMCoCC‐1200) are coupled with...
Regulation of the growth of vascular endothelial cells (ECs) and smooth muscle cells (SMCs) with artificial vascular grafts at vascularization is well‐known to regenerate functional blood vessels for treating cardiovascular disease; however, little research has been published on this subject. Here, a novel polymer vascular graft is presented, whose inner surface contains an assembled circular microgroove...
A CdS/reduced graphene oxide (RGO)/ZnO nanowire array (NWAs) heterostructure is designed, which exhibits enhanced photoelectrochemical (PEC) activity compared to pure ZnO, RGO/ZnO, and CdS/ZnO. The enhancement can be attributed to the synergistic effect of the high electron mobility of ordered 1D ZnO NWAs, extended visible‐light absorption of CdS nanocrystals, and the formed type II band alignment...
