Gallium self-diffusion in gallium phosphide
Ga self-diffusion in gallium phosphide ~GaP! is measured directly in isotopically controlled GaP heterostructures. Secondary ion mass spectroscopy ~SIMS! is used to monitor intermixing of Ga and Ga between isotopically pure GaP epilayers which are grown by molecular beam epitaxy ~MBE! on GaP substrates. The Ga self-diffusion coefficient in undoped GaP is determined to be D52.0 cm s exp(24.5 eV/...

متن کاملGallium in cancer treatment.
The trivalent gallium cation is capable of inhibiting tumor growth, mainly because of its resemblance to ferric iron. It affects cellular acquisition of iron by binding to transferrin, and it interacts with the iron-dependent enzyme ribonucleotide reductase, resulting in reduced dNTP pools and inhibition of DNA synthesis. The abundance of transferrin receptors and the up-regulation of ribonucle...
متن کاملDevelopment of gallium compounds for treatment of lymphoma: gallium maltolate, a novel hydroxypyrone gallium compound, induces apoptosis and circumvents lymphoma cell resistance to gallium nitrate.
Clinical studies have shown gallium nitrate to have significant antitumor activity against non-Hodgkin's lymphoma and bladder cancer, thus indicating that gallium-based drugs have potential for further development as antineoplastic agents. In this study, we compared the cytotoxicity of gallium maltolate, a novel gallium compound, with gallium nitrate in lymphoma cell lines, including p53 varian...
متن کاملGallium cluster "magic melters".
Calorimetry measurements (using a method based on multicollision induced dissociation) have been performed for unsupported gallium clusters, Gan+ (n = 30-50 and 55). Melting transitions have been identified from spikes in the heat capacities recorded as a function of temperature. There are enormous fluctuations in the melting temperatures and the heats of fusion with cluster size. Clusters with...
