Effects of sol-gel synthesis on 5Fe-15Mn-40Zn-40Ti-O mixed oxide structure and its H2S removal efficiency from industrial gas streams
(2009)A novel Fe-Mn-Zn-Ti-O mixed metal oxide has been developed for efficient low-temperature (25-50°C) removal of H2S from a gas mixture containing 600 ppm H2S, 25 vol% H2, 7.5 vol % CO 2, and 1-3 vol% H2O that simulates typical ...

Magnetoresistance in LaNi1-xCoxO3 (0.3≤x≤0.6)
(2010)We report on a detailed study of the electrical resistivity and the magnetoresistance of the metallic members of the LaNi1-xCoxO3 series with 0.3≤x≤0.6. The low-temperature resistivity of the compounds with 0.3≤x≤0.5 ...

On the modeling of semisolid suspensions
(2008)Due to the distinct rheology of semisolid slurries the process has well established advantages over competing near-net-shape manufacturing technologies. Despite the obvious advantages of the process its adoption by the ...

Predictions of structure breakdown, buildup and shear banding in semisolid suspensions
(2008)When SSM material is subjected to a sudden transient the rate of buildup (aging) is negligible compared to the rate of breakdown (shear rejuvenation). While this is generally true, due to prolonged processing or the geometry ...
