Bone Transplantation for Fracture of Lumbar and Thoracic Vertebrae Through Hollow Bone-planting Appliance;

Construction technology of hollow and high pier of railway bridge;

The preparation and application of hollow core-shell structured nanomaterials were introduced in this article.

The article introduces the main characteristics and application prospect of prestresses reinforced concrete hollow square pile.

Prefabricate hollow square pile is a kind of new pile,of which performance is between the solid square pile and prestressed pipe pile.

Electroless plating Co-P alloy on the surface of fly ash cenospheres;

Nanocomposite microwave absorbing coatings were prepared by using prepared Ni-Co-P/CNT and Ni-Co-P/fly ash cenospheres composite powders as absorbers,choosing epoxy resin as film forming resin and adding some proper solvent,curing agent and auxiliary agents.

NiS2 hollow microspheres were prepared by hydrothermal reaction between NiCl2·6H2O and Na2S2O3·5H2O at the low temperature of 150°C.

Subsequently, the similar microstructured NiO hollow microspheres were obtained by calcining the above precursor at 400 ℃ for 2 h.

NiS hollow microspheres were synthesized by the reaction of nickel acetate and thioacetamide inethanol at 150 ℃.
