The distribution of gallium(b) and indium (b) between hydrochloric or sulphuric acid solution with sec-nonylphenoxy acetic acid(CA-100) in kerosene has been investigated under various conditions. CA-100 is a new organocarboxylic extractant, which has been shown to be efficient for gallium(b) and indium(b) where...

The kinetics and equilibria of binding of gallium(III) to the 8-hydroxyquinoline (HQ) have been investigated in water and in the presence of sodium dodecyl sulfate (SDS) micelles. Moreover, the pKA1 and pKA2 of HQ and first hydrolysis constant of Ga3+ ion have been measured in water and SDS solution. The analysis of the kinetic and thermodynamic behavior reveals that the reactive form of Ga(III...

We applied the laser interference lithography method to form a patterned sapphire substrate (PSS). A three-dimensional photonic crystal was formed by autocloning the PSS with alternate Ta2O5/SiO2 coatings. A high total integrated reflectance (TIR) band was obtained around the 410 to 470 nm wavelength range that matched the emission spectrum of the gallium nitride (GaN) light-emitting diode (LED...

Gallium nitrate is active against lymphoma and bladder cancer; however, little is understood about tumor resistance to this drug. Transferrin, the iron transport protein, increases gallium uptake by cells, whereas pyridoxal isonicotinoyl hydrazone (PIH), an iron chelator, transports iron into cells. Therefore, we examined whether these metal transporters would increase the cytotoxicity of galli...
