Sonochemical synthesis and characterization of iron oxide coated on submicrospherical alumina: a direct observation of interaction between iron oxide and alumina

Article Abstract:

A study was conducted to analyze the coating of iron oxides on submicrospheres of alumina using the sonochemical technique. Three types of alumina were utilized. Results indicated various coating effects on different heat-treated substrates. Findings also showed a strong interaction between iron oxides and alumina substrate. In addition, the presence of haematite influences the formation of alpha-Al2O3 at high temperatures.

Mechanism of diethyl ether formation on Ag(110) and its dependence on coadsorbed oxygen species

Article Abstract:

A study was conducted on the nature of the chemical reactions of alkyl groups with oxygen-covered metal surfaces in connection with the heterogeneous partial oxidation of hydrocarbons. Several surface mixtures of ethyl and ethoxide species were prepared to probe the mechanism of diethyl ether formation on Ag(110) using temperature programmed desorption methods. Results of the study are discussed.
