    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic Force Microscopy; Nonlinear dynamics; Soft materials; High- speed friction measurements; Modeling and numerical simulations; Fysik; Physics;

    Sammanfattning : Investigating visco-elastic forces at the nanometer-scale is important to thecharacterization of soft materials. A quantitative force measurement can be ob-tained using an atomic force microscope (AFM) with a calibrated force transducer(the AFM cantilever). LÄS MER

  4. 13. Glass Transition Dynamics in Soft Condensed Matter

    Författare :Johan Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer films; beta relaxation; hydrogen bond; glass transition; polymer dynamics; cooperativity; confinement; IXS; Brillouin light scattering; excess wing;

    Sammanfattning : Materials of very different character, ranging from polymers to metals can be made into glasses. The structural and dynamical properties of glass-forming materials are fundamentally different from those found in crystals. Hence, glassy materials exhibit unique characteristics, which make them suitable for a wide range of applications. LÄS MER
