In this study, a simple method to coat mesoporous silica layer onto solid silica spheres in a controlled manner via a two-step procedure is reported. Core/shell structured SiO 2 μ-SiO 2 spheres with different shell thickness have been obtained by the application of the optimized hexadecyl trimethyl ammonium bromide/tetraethylorthosilicate (CTAB/TEOS) ratio. The specific surface areas...
The hydrogen bond induced acid-soap like complex has been prepared from a nitrogen-containing heterocyclic compound, pyrrolidine, and the myristic acid (MA). The complex composition and the intermolecular actions between two component molecules have been characterized with techniques of nuclear magnetic resonance (NMR), X-ray diffraction (XRD) and Fourier transformation infra-red (FTIR) spectroscopy...
TiO 2 nanocrystal/nanotube hybrids were presented and prepared by incubating non-prefabricated TiO 2 nanocrystals in anodized TiO 2 nanotubes. TiO 2 nanocrystals were incubated inside the nanotubes with tuning size and aggregation morphology by means of a block copolymer-assisted evaporation induced self-assembly (EISA) process. Compared with that of the bare TiO ...
Single-crystalline gold nanoplates and also nanobelts, with {111} crystallographic facets and size length longer than 20μm, are synthesized in large scale by reduction of HAuCl 4 in lyotropic liquid crystal phases. Such flat products can be obtained from different systems including hexagonal or lamellar phases made of P123 (EO 20 PO 70 EO 20 ) where different ionic...
