Alpha-ferric oxide, chromic oxide, activated carbon, and graphite were examined as a support medium for a 68Ge 68Ga generator stable against chemicals and radiation. Alpha-ferric oxide is found to be a suitable material for the generator. The elution yield of 68Ga from the column of α-ferr...
Alpha-ferric oxide in trigonal structure is found to be a suitable material for the generator. The elution yield of 68 Ga from the column of trigonal crystal of 伪-ferric oxide with absorbed 68 Ge(IV) can reach 90% in 1 ml 0.05 mol/l HCl solution, while the breakthrough of 68 Ge ...
ALPHA-FERRIC OXIDE AND ITS PRODUCTIONPURPOSE: To produce superfine nonacicular α-ferric oxide particles each made of a single crystal, having a narrow particle size distribution, minimizing flocculation energy because of the most stable surface state as particles and remarkably excellent in ...
Iron oxide, Fe2O3, is a promising material for water splitting reaction using solar energy due to its stability and optimal bandgap of 2 eV. Even the recent efforts, however, using Fe2O 3 thin film materials reported low efficiencies due to poor carrier transport within these films.;A ...
68 Ge 68 Ga generator with alpha-ferric oxide support in trigonal structure The absorption behavior of 68 Ga(III) and 68 Ge(IV) on three different type of ferric oxides has been studied. Alpha-ferric oxide in trigonal structure is found to be a suitable material for the generator. The ...
