Evolution of a lamellar domain structure for an equilibrating lyotropic liquid crystal

Article Abstract:

A demonstration that the morphology of the lamellar phase varies significantly across that range and that the rate of equilibrium depends strongly on concentration with, paradoxically, the faster equilibrium at higher surfactant concentrations is conducted by magnetic resonance (NMR) and scanning electron microscopy (SEM). Results reveal that the 25-wt percent sample exhibits a defect-rich local structure, characteristic of superposed L3 character.

Ga-asssisted synthesis and optical properties of ZnO submicron- and nanotowers

Article Abstract:

A synthesis of tower-like ZnO submicron- and nanostructures is performed by simply evaporating a mixture of Zn and Ga. Scanning electron microscopy and transmission electron microscopy observations revealed that the regular hexagonal tower-like structure is likely to be made up in a layer-by-layer fashion and consist of sheets.

Hydrothermal growth and optical properties of doughnut-shaped ZnO microparticles

Article Abstract:

Doughnut-shaped ZnO microparticles is grown through a hydrothermal reaction in citrate solution at 120 degree Celsius. Field emission scanning electron microscopy (FESEM) reveals that these microparticles consist of regular arranged nanoplates, and there is a concave on the surface of each microparticle.
