The effect of submicron‐sized particles on the corrosion of copper has been investigated in mixtures at 373 K and relative humidities (RH) of 65, 75, and 88%. At 65% RH, particles do not affect the oxidation of copper. At 75% RH, the "critical relative humidity" of , localized formation of and a basic copper sulfate,…

Supercritical carbon dioxide is known to be a very good swelling agent and plasticiser for poly(methyl methacrylate), a consequence of an interesting combination of liquid-like and gas-like properties exhibited by supercritical fluids. Making use of this behaviour, we have studied a constant temperature process of gen…

Photo‐ and electroactive amorphous molecular materials are attractive for use in electronics, for example in pn heterojunction‐type photovoltaic devices or in electroluminescent devices. The title compound (based on that in the Figure) exhibits a high glass transition temperature, hardly crystallizing even above this…

Early investigations into partial discharge (PD) phenomena are reviewed to illustrate how little has changed and how much has, in some respects, been repeated during the forty years from 1940 to 1980. The early days of PD research included studies of PD in gas-fi…

Silicon is used in the fabrication of microelectromechanical systems (MEMS). The friction and wear characteristics are of major design concern for any mechanical device requiring relative motion. In the present investigations we have studied the influence of ion bombardment on the microstructure, crystallinity, compos…

Amorphous hydrogenated carbon (a-C:H) films and hydrocarbon films containing transition metals (Me-C:H) were prepared by glow discharge and reactive sputtering techniques at relatively low substrate temperatures (100 - 200°C). The tribological properties of both these types of coating materials will be compared. For s…
