Despite being one of the most promising materials in anode materials, molybdenum sulfide (MoS2) encounters certain obstacles, such as inadequate cycle stability, low conductivity, and unsatisfactory charge‐discharge (CD) rate performance. In this study, a novel approach is employed to address the drawbacks of MoS2. Carbon polymer dots (CPDs) are incorporated to prepare three‐dimensional (3D) nanoflower‐like...
Cerium‐Based Metal–Organic Framework Nanosheets
In article number 2300597, Liang Zhao and co‐workers construct a 3D layered Ce–metal–organic framework (MOF) by rational chloride‐capped metal nodes design and structure‐directed morphology control. The obtained layered MOF can be easily exfoliated into ultrathin 2D monolayer MOF nanosheet, exhibiting excellent performance for the selective oxidation...
The development of methodologies for inducing and tailoring activities of catalysts is an important issue in various catalysis. The ultrathin 2D monolayer metal–organic framework (MOF) nanosheets with more accessible active sites and faster diffusion obtained by exfoliating 3D layered MOFs are of great potential as heterogeneous catalysts, but the rational design and preparation of 3D layered MOFs...
Electrochemical N2 fixation requires effective electrocatalysts to expedite the nitrogen reduction reaction (NRR) kinetics and suppress the concomitant hydrogen evolution reaction (HER). Although transition metal sulfides have been deemed as efficient NRR electrocatalysts, it remains a great challenge to suppress the serious HER to achieve high Faradaic efficiency (FE). Herein, vanadium disulfide...
In vivo fluorescence imaging can perform real‐time, noninvasive, and high spatiotemporal resolution imaging to accurately obtain the dynamic biological information in vivo, which plays significant roles in the early diagnosis and treatment of cancer. However, traditional in vivo fluorescence imaging usually operates in the visible and near‐infrared (NIR)‐I windows, which are severely interfered by...
Many enveloped viruses utilize endocytic pathways and vesicle trafficking to infect host cells, where the acidification of virus‐containing endosomes triggers the virus‐endosome fusion events. Therefore, simultaneous correlation of intracellular location, local pH, and individual virus dynamics is important for gaining insight into viral infection mechanisms. Here, an imaging approach is developed...
Constructing a stable solid electrolyte interphase (SEI) on high‐specific‐capacity silicon (Si) anode is one of the most effective methods to reduce the crack of SEI and improve the cycling performance of Si anode. Herein, the authors construct a reinforced and gradient SEI on Si nanoparticles by an in‐situ thiol‐ene click reaction. Mercaptopropyl trimethoxysilane (MPTMS) with thiol functional groups...
Blocking immune checkpoint pathways with an antibody or small interfering RNA (siRNA) has become a promising method to reactivate antitumor responses for cancer treatment. However, both blockade strategies achieve only temporary inhibition of these immune checkpoints. Herein, a photoswitched CRISPR/Cas9 system for genomic disruption of the PD‐L1 gene is developed to achieve permanent blockade of the...
PtPb@Pt catalysts are very useful and widely applied in various industrial reactions. Here, the phase stability of such catalysts is compared in both CO gas and vacuum conditions at elevated temperatures using aberration‐corrected in situ transmission electron microscopy (TEM). A Pt aggregation process takes place affected by CO gas, which results in direct exposure of the PtPb core to CO. A phase...
Herein, a surfactant‐ and additive‐free strategy is developed for morphology‐controllable synthesis of cobalt pyrophosphate (CoPPi) nanostructures by tuning the concentration and ratio of the precursor solutions of Na4P2O7 and Co(CH3COO)2. A series of CoPPi nanostructures including nanowires, nanobelts, nanoleaves, and nanorhombuses are prepared and exhibit very promising electrocatalytic properties...
