Layered manganese‐based oxides (LMOs) are promising cathode materials for sodium‐ion batteries (SIBs) due to their versatile structures. However, the Jahn–Teller effect of Mn3+ induces severe distortion of MnO6 octahedra, and the resultant low symmetry is responsible for the gliding of MnO2 layers and then inferior multiple‐phase transitions upon Na+ extraction/insertion. Here, hexagonal P2‐Na0.643...
In this paper, strong hydrophilic poly(ionic liquid)s (PILs) are selectively grafted on different positions (mesoporous channels and outer surface) of mesoporous silica via thiol‐ene click chemical reaction. The purposes of selective grafting are on the one hand, to explore the differences of adsorption and transportation of water molecules in mesoporous channels and on the outer surface, and on the...
Magnetic resonance imaging (MRI) is a superior and noninvasive imaging technique with unlimited tissue penetration depth and superb spatiotemporal resolution, however, using intracellular self‐assembly of Gd‐containing nanoparticles to enhance the T2‐weighted MR contrast of cancer cells in vivo for precise tumor MRI is rarely reported. The lysosomal cysteine protease cathepsin B (CTSB) is regarded...
A highly efficient g‐C3N4 photocatalyst is developed by a novel one‐pot thermal polymerization method under a salt fog environment generated by heating the aqueous solution of urea and mixed metal salts of NaCl/KCl, namely SF‐CN. Thanks to the synergistic effect of the oxygenation and chemical etching of the salt fog, the obtained SF‐CN is an oxygenated ultrathin porous carbon nitride with an intermolecular...
Limited by the insufficient active sites and the interference from breath humidity, designing reliable gas sensing materials with high activity and moisture resistance remains a challenge to analyze human exhaled breath for the translational application of medical diagnostics. Herein, the dual sensing and cooperative diagnosis is achieved by utilizing metal‐organic frameworks (MOFs) and its derivative...
Dual Sensing
In article number 2203715, Tingting Zhou, Tong Zhang, and co‐workers propose the “dual sensing and cooperative diagnosis” route, taking advantage of the versatility of metal–organic frameworks (MOFs) and their derivatives. The sensors based on Fe‐MIL‐101‐NH2 and its derived Co/Ni/Fe trimetallic oxides show high sensitivity for detecting humidity and biomarker gas of diabetes in exhaled...
In recent years, rapid advances are achieved in polymer solar cells (PSCs) using nonfullerene small molecular acceptors. However, no research disclosing the influence of molecular weight (Mn) of conjugated polymer on the nonfullerene device performance is reported. In this work, a series of polymers with different Mns are synthesized to systematically investigate the connection between Mn and performance...
