A porphyrin derivative possessing orthogonal self-assembly units displays in situ reversible transformation of aggregate morphology between nano-rods and hollow spheres upon exposure to different solvents.

Titania coated magnetic hollow mesoporous silica spheres with high surface area were created, which can be used in efficient and rapid capture of phosphopeptides from peptide mixtures.

Tin oxide (SnO2) hollow spheres modified with titanium dioxide (TiO2) nanowires (NWs) synthesized by sequential hydrothermal reactions were investigated as photoanodes for dye-sensitized solar cells. Not only does the hydrothermal treatment form numerous short TiO2 NWs on the surface of SnO2 spheres, but also passivates the surface of SnO2. Consequently, the specific surface area of the photoan...

Hollow spheres of MCM-41 mesoporous aluminosilicates, with two small holes on the shell, have been synthesized from a surfactant-aluminosilicate gel composite.

Monodisperse hollow silica spheres of uniform size and ordered mesoporous shells have been successfully fabricated in water/heptane/CTAB nanoemulsions induced by compressed CO(2).

Fluorinated polysilsesquioxane (FPSQ) hollow spheres with a large empty interior were synthesized in an aqueous medium by using (trifluoropropyl)trimethoxysilane as the sole precursor. The drug release applications of these spheres were demonstrated, and the materials have great potential as fluorinated drug release carriers.

Adv. Mater. 2009, 21, 1–5 2009 WILEY-VCH Verlag Gmb The synthesis of new porousmaterials remains an exciting area of research, in part because of their potential use in diverse applications. Materials having hierarchically porous nanostructures (such as bimodal mesoporous, meso–macroporous, or mesoporous–hollow materials) are particularly intriguing because they can uncouple overall mass transp...

Black titania spheres (H-TiO2-x) were synthesized via a simple green method assisted by water plasma at a low temperature and atmospheric pressure. The in situ production of highly energetic hydroxyl and hydrogen species from water plasma are the prominent factors in the oxidation and hydrogenation reactions during the formation of H-TiO2-x, respectively. The visible-light photocatalytic activi...
