Hollow core/shell hematite microspheres with diameter of ca. 1-2 μm have been successfully achieved by calcining the precursor composite microspheres of pyrite and polyvinylpyrrolidone (PVP) in air. The synthesized products were characterized by a wide range of techniques including powder X-ray diffraction (XRD), field-emission scanning electron microscopy(More)
Sieve and take: A biomimetic strategy was designed to fabricate two-dimensional silica sieve plates (SSP) by use of catanionic surfactants as composite template and L-tartrate with hydroxyl and carboxyl groups as regulator. Tartrate was found to combine two capabilities in the formation of SSP structures: the connection of adjacent silica structures through(More)
Biogenetic silica displays intricate patterns assembling from nano- to microsize level and interesting non-spherical structures differentiating in specific directions. Several model systems have been proposed to explain the formation of biosilica nanostructures. Of them, phase separation based on the physicochemical properties of organic amines was(More)
