Inorganic Fluorides

Alkaline earth fluorides are important materials in the electronics industry because of their use in the epitaxial growth of semiconductor-on-insulator (SOI) devices. Their main advantages are their close lattice match with the common semiconductors, and the fact that they evaporate as molecular units upon heating which implies good control of film stoichiometry in Molecular Beam Epitaxy. More recently, further interest has developed relating to their use in nanolithography because they are materials which can be suitably patterned with an electron beam in device processing.Moreover, some inorganic fluorides potentially offer inherently higher resolution than resists so far used.Various studies have been made on the effects of irradiation on these Group IIA fluorides. It has also been noted during electron microscope characterization of the SOI structures that these fluorides are very easily damaged. Since image detail is lost, it has been suggested that the fluorides are becoming amorphous.

Gear Oils

In this study, the friction and wear properties of six different new and used wind turbine gear oils (ISO VG 320), with different base oil formulations and additives packages, were investigated. For that purpose, a four-ball tribometer and an Optimol SRV were used. Moreover, the lubricants extreme pressure properties were also evaluated, using the same four-ball tribometer. The study also includes a characterization of the lubricants. The main objective was to compare the new and used gear oils in order to identify performance differences and predict oil change intervals. The results indicate that a use of 3 to 4 years is within the lifetime of the lubricant.
