   Sammanfattning : Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior. LÄS MER

3. 2. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation

   Författare :Apurve Saini; Max Wolff; Vassilios Kapaklis; Pietro Tierno; Uppsala universitet; []

   Sammanfattning : This thesis presents experimental investigations of the electronic structure of emerging and novel cathode materials used in lithium- and sodium-ion batteries. The investigated materials include a range of oxide materials containing the elements nickel and manganese. LÄS MER

5. 4. Jamming and Soft-Core Rheology

   Författare :Daniel Vågberg; Peter Olsson; Teitel Stephen; Vitelli Vincenzo; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; jamming; rheology; soft matter; granular material; SLLOD; critical point; critical scaling;

   Sammanfattning : Many different physical systems, such as granular materials, colloids, foams and emulsions exhibit a jamming transition where the system changes from a liquid-like flowing state to a solid jammed state as the packing fraction increases. These systems are often modeled using soft-core particles with repulsive contact forces. LÄS MER

7. 5. 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
