Yong Sheng Zhao et al.
Journal of nanoscience and nanotechnology, 7(3), 1021-1027 (2007-04-25)
Copper/lophine core/shell nanocomposites were fabricated through the self-assembly of lophine on the surfaces of copper nanostructures. The growth of the lophine shells was induced by the cooperation of coordination and several other noncovalent interactions. The dimensions, structures, and morphologies of

Nanocrystals in the size range 12-21 nm of a model binary ionic material in the wurtzite (B4) structure were constructed with morphologies which minimize the surface energy. These were then embedded in a pressurization medium, consisting of a binary Lennard-Jones-type

Lophine (2,4,5-triphenylimidazole) derivatives as versatile analytical tools in biomedical sciences are described. Chemiluminescence (CL) and fluorescence (FL) properties of the lophine derivatives are first demonstrated including the CL reaction mechanism, effects of substituents on CL yields, FL spectral behaviors, etc.

Laser flash photolysis of the photocyclization of triphenylimidazole (TPI) in ethyl alcohol at 308 nm. indicates that the dihydrophenanthroimidazole (DHPI) intermediate is produced rapidly, has a lifetime of 0.25 ms, and returns predominantly back to triphenylimidazole. Analysis of the decay

A rapid and convenient flow-injection method is described for the determination of Co(II). The method utilized the phenomenon that the lophine-Co(II)-H2O2 chemiluminescence (CL) reaction is enhanced in alkaline media by the addition of hydroxylammonium chloride. The calibration curve was linear

Graphene has emerged as the new wonder material. Being only one atom thick and composed of carbon atoms arranged in a hexagonal honeycomb lattice structure, the interest in this material has exploded exponentially since 2004 when it was first isolated and identified using a very simple method.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
