Enhanced activity of Au catalysts from extra-high surface area CeO 2 for CO oxidation

Ling-Yun Jin、Cun-Xia Guo、Yuejuan Wang 等 5 位作者2011-08-01OpenAlex

A series of Au/CeO2 catalysts has been prepared with CeO2 of varying surface areas and tested for low-temperature CO oxidation. With a higher surface area support, the Au/CeO2 catalysts show a higher catalytic activity for CO oxidation (0.175 molCO gAu -1 h at 0 °C). Higher oxygen vacancies provided by the formation o…

Rise in energy product of Sm-Co/Fe spring exchange magnetic bilayers with addition of Cr at interface

Furrukh Shahzad、Saadat Anwar Siddiqi、Xu Jing 等 5 位作者2011-08-01OpenAlex

Sm-Co/Fe bilayers are deposited by DC and RF magnetron sputtering on 70 nm Cr buffered Si (100) substrate at an elevated temperature of 650°C. Thickness of Sm-Co and Fe is fixed as 20 nm and 10 nm, respectively. Magnetic behavior with very thin Cr layers (0.3-0.7 nm) at interface of Sm-Co and Fe is studied. All the sa…

Effect of Sb incorporation on the density of defect states in a-Se 90 In 10 glassy alloy

Samiksha Shukla、S. P. Singh、Shailesh Kumar2011-08-01OpenAlex

behaviour is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, the density of defect states (DOS) near Fermi level has been calculated. It is found that…

The influence of impact loading on the fatigue life of EA4T steel

Khalil Farhangdoost、Amir Malekzadeh、Saeid Hadidi Moud2011-08-01Pure (Coventry University)

There are many situations where structural components are subjected to combined impact and fatigue loading. It is evident that the impact strength of metallic materials changes following a history of fatigue loads. Similarly, the fatigue behaviour of metallic materials (fatigue strength and fatigue life) changes after…
