Liquid phase oxidation of cyclohexane using bimetallic Au-Pd/MgO catalysts

A detailed study of the selective oxidation of cyclohexane has been performed using bimetallic gold–palladium catalysts supported on magnesium oxide. Mono-metallic supported gold or palladium catalysts show limited activity for cyclohexane oxidation. However, a significantly enhanced catalytic performance is observed when supported gold–palladium alloy catalysts are used for this particular reaction. This synergy is observed for alloys spanning a wide range of gold-to-palladium molar ratios. Mechanistic studies reveal a promotion effect that occurs from alloying palladium with gold on the supported catalyst, which significantly improves the homo-cleavage of the O–O bond in cyclohexyl hydroperoxide, an important intermediate species in cyclohexane oxidation

Attitudes Towards Computer In An Information-Intense Environment: A Field Study Of The Insurance Industry

The topic of human attitudes about computers has been dealt with extensively in both the academic and popular literature, but it remains an issue of importance.  The continued relevance was well illustrated by the Soviet chess grandmaster, Karpov, who recently remarked that he was not afraid to lose a chess game to a computer, but that people who worked with such computers could lose their soul to the machines (Hooper, 1990).  The beliefs which people hold toward computers will affect their computer interaction and their willingness to adapt to automated systems:  therefore the issue is of great practical importance.  This paper reports on a replication of an early IBM study with the intent of assessing contemporary attitudes towards computers and the changes in attitudes over the last 25 years
