Open Seminar at Karlstad University Seminar Series Organized by the Department of Engineering and Chemical Sciences Spring Semester 2017
Prof. Lars Järnström, Dept. of Engineering and Chemical Sciences, Karlstad University
gives a seminar entitled
Structures in suspensions studied by conventional rheology and microrheolog
Monday, May 22nd at 2:30 pm
Place: Room 3B 512
Ternary Silica-Pluronic-Starch thermosensitive systems were studied by means of conventional rheology and microrheology. Scaling relations were used to identify transitions from a colloidal gel (or a liquid-like state at low temperatures) to a colloidal glass (or microcrystalline regions). Microrheology at low volume fractions solid phase gave insights into local structural and dynamical properties accompanying the sol-gel transition, not visible by conventional rheology.
Welcome Lars Järnström, Professor, organizer of the seminar.
