We synthesized a honeycomb-ordered Na3Ni2SbO6 compound and investigated the phase transformation mechanism and Na+ kinetics during sodium (de)intercalation. The partial irreversible O∩3每P∩3 phase transition is found to be responsible for the insufficient cycling stability. The fast Na+ mobility in the interlayer establishes the linkage between the kinetic advantage and a good rate performance of the cathode.

After the injection of liquid metal into the wrist intervaginal space comprising tendons, vessels, and nerves, the liquid metal wrapped around the fascial space and finally reached the fingertip downstream and armpit upstream in addition to the neurovascular bundle without vessels or lymph nodes. During the invasion of the tumor along the route, the integrity of the fascia is destroyed. The liquid metal may enter the tumor through the damaged spot, finally reach the inside of the tumor through the fascia fiber network, and wrap the tumor cells. As a result, tumor growth is obstructed and the tumor experiences partial necrosis and becomes hollow inside.

Highly doped single atom catalyst was prepared via a single-step pyrolysis of glucose, dicyandiamide, and inorganic metal salts (Fe, Co, Ni, Cu, and Pt). High-angle annular dark field-scanning transmission electron microscopy (HAADF-STEM) and X-ray absorption fine structure spectroscopy (XAFS) techniques revealed that nitrogen atoms doped into the graphene matrix were pivotal to the stabilization of metal atoms by generating a metal-Nx coordination structure. Single iron-doped hybrid (Fe@N-doped graphene), as a representative, showed an excellent electrocatalytic performance for oxygen reduction reaction. This work provided a feasible approach for the design and fabrication of highly doped isolated metal catalysts with practical applications.

汐-MoO3 belt crystals consisting of nanosheets stacked along their [010]-axes have been synthesized (without intentional use of a substrate) and further exfoliated to form 2D nanosheets. Raman mode softening of Ag (~818 cm−1) was observed from the thinner layers and theoretically validated for the first time. Aqueous exfoliation induces a blue shift in the 汐-MoO3 nanosheet absorption edge.
