Ceramic hollow spheres of MoS2 and MoO3 were obtained by sonochemical synthesis of MoS2 and MoO3 templated on silica nanoparticles (diameters 50-500 nm) followed by acid etching to remove the silica c...
Non-hollow In(2)O(3) particles with hexagonal rod- and disk-shapes are generated from the calcination of porous CPPs; however, elongated hexagon-, ellipsoid-, and rod-shaped hollow In(2)O(3) particles...
Fifty and one-hundred micrometer diameter nanostructured gold hollow microspheres (GHSs), in >98% purity, have been prepared by using ceramic hollow spheres, CHSs, as templates. Tennanometer diameter ...
A novel composite hierarchical hollow structure is reported. The as-prepared products consist of discrete WO(2) hollow core spheres with W(18)O(49) nanorod shells ("hollow urchins"). The products show...
ITI implants, which are transmucosal from the time of placement, require relatively few components or instruments for the procedures involved in prosthetic restoration. The salient features of postsur...
