    Sammanfattning : Micron to millimetre sized droplets, precisely generated or sustained in controlled environment, have great potential in myriads of engineering applications functioning as the basic element to assemble metamaterials, deliver drugs, host surfactant, reduce friction and damp turbulence. The interaction of droplets from pairwise to collective levels is the most important factor in controlling these processes, yet little is known about the detailed mechanisms in various nonideal conditions.

  3. 7. Fundamental Processes in SiO2 under Ion Bombardment

    Författare :Harald Jacobsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigations of sputtering, electron emission and oxide growth under 40-300 keV H+, He+, N+, Ne+, Ar+, Kr+ and Xe+ ion bombardment of SiO2 are presented in this thesis. To accurately determine SiO2 sputtering yields, a new measurement method was developed where the electron emission was monitored during sputtering through thin SiO2 films on Si substrates. LÄS MER
