In the seed-mediated synthesis of Pd每Pt bimetallic nanodendrites, both the homogeneous and heterogeneous nucleation of Pt occurred at the very early stages of the synthesis and the growth of Pt branches mainly proceeded via particle attachment. These Pd每Pt nanodendrites showed greatly-improved activities for the oxygen reduction and formic acid oxidation reactions as compared to foam-like Pt aggregates prepared in the absence of Pd seeds.

Well-defined platelet-like hydrazine每cadmium tellurite hybrid microcrystals can be produced by a solvothermal reaction in mixed solvents. These microcrystals are an appropriate precursor for the construction of porous cadmium telluride and nanoporous tellurium architectures through combined thermal decomposition and dissolution treatment or in situ topotactic reactions.

Nano Res (2010) 3: 92每97

Address correspondence to

An in situ transmission electron microscopy observation of the dynamic entrapment of a C60 molecule in the saddle of a bent double-walled carbon nanotube is presented. The fullerene interaction is non-covalent, indicating that enhanced van der Waals forces are responsible. Classical molecular dynamics calculations confirm that the increased interaction area associated with a buckle is sufficient to trap a fullerene. Moreover, they show hopping behavior in agreement with our experimental observations.
