The prompt nuclear reaction 16 O(d,p 1 ) 17 O and the resonant alpha backscattering 16 O(α,α) 16 O spectroscopies are used for the measurement of the oxide layer thickness on brass; these methods are subjected to a critical comparison. The study of

Supported uranium oxides were prepared on commercial SiO 2 , TiO 2 , Al 2 O 3 , and MgO carriers, and characterized by a variety of physicochemical techniques. Simultaneous thermoanalytical techniques (TG, DTA, DTG) allowed a mechanism to be proposed

The adsorption of O 2 and initial step of oxidation have been investigated, mainly at room temperature, for three different α-CuZn (75%Cu/25%Zn) surfaces ((110), (100) and (111)) by XPS. XAES, LEED, CPD and HREELS. No superstructures were detected o

Unsupported USbO 5 and USb 3 O 10 catalysts are characterized by BET measurements and a 13 C-NMR study of adsorbed propylene. It is shown, by both techniques, that USbO 5 essentially contains micropores ( R R 3 O 10 contains both mesopores with R R >

The oxidation of the α and β phases of brass is studied between 293 and 673 K by means of prompt nuclear reactions, resonant alpha backscattering, and X-ray photoelectron spectroscopy. The oxide layer thickness is obtained from the nuclear methods

Using high resolution electron energy loss spectroscopy (EELS), we have measured three vibrational bands on a clean CuZn α 75/25 (110) surface after O2 exposure. The band at 420cm-1 is related to the metal-O stretchifig vibration. The band around 36

X-ray photoelectron spectroscopy has been used to study the oxidation of polycrystalline α(75%Cu/25%Zn) and β(53%Cu/47%Zn) brass. The process was conducted in pure oxygen (10-7 ⩽ PO2 ⩽10-3 Torr) at temperatures between 298 and 433 K. By a caref
