(2003-10-22)Biomembranes are complex two-dimensional fluids consisting of proteins and lipids. In this work, simple molecular models are developed, applied and discussed to describe the thermodynamic ... -
Einfluss von gelöstem Wasserstoff auf die Versetzungsbildung bei plastischer Verformung von Metallen
(2016-03-11)Dissolved hydrogen in metals leads in many cases to a reduction in the quality of mechanical properties. There are many effects that can be attributed to the solution of hydrogen. These are collectively referred to as ... -
Der Einfluss von Rotation auf Konvektion und Kristallisation eines binären eutektischen Systems in Hinblick auf den Erdkern
(2000-09-22)In the cooling Earth the fluid outer core consists of a molten alloy over the solidifying inner core. Here, compositional convection due to the preferential solidification of the heavy phase ... -
Einzelmolekülstudien auf Nanoskalen: STED Fluoreszenzfluktuationsspektroskopie
(2009-06-17)Fluorescence Microscopy Methods are widely used in the Life Sciences to visualize and spectroscopically analyze biologically processes. Single molecule methods, such as FCS (Fluorescence ... -
Elastic and viscoelastic deformation of glass plates by excimer laser induced stresses and patterned silicon suboxide films
(2021-10-28)A mechanically stressed film can cause a bending of the underlying substrate. Usually, the substrate deforms elastically, but in special cases a plastic or viscous deformation can be observed. Such deformations are mostly ... -
