Prof. Kazuya Saito (University of Tsukuba)09/07/2015, 12:00Our previous study based on structural thermodynamics [1-3] established that the conformation of alkyl chains attached to the end(s) of the rigid core part of mesogenic molecules is fully molten in any liquid crystalline (LC) mesophases. Besides, recently revealed is that the nano-segregated structure is a fundamental structure for layered (smectic) LCs formed by such molecules [4,5]....Go to contribution page

Recently, we have developed a self-healing material using a particle/liquid-crystal (LC) composite gel containing an azobenzene compound. The particle/azo-doped LC composite gel showed the gel–sol transition by the trans–cis photoisomerization of an azo dopant. The photoinduced gel–sol...Go to contribution page

Dr Ewa Dryzek (Institute of Nuclear Physics PAN, Kraków)09/07/2015, 12:50soft matter and glassformersProbing of intermolecular or intramolecular regions in molecular solids by positron annihilation lifetime spectroscopy (PALS) is well established. In such substances, the formation and decay of positronium (Ps) – the positron-electron bound state is expected to be influenced by the nature of intermolecular interactions and the internal structure. Structural changes, phase transformations and...Go to contribution page

In other fields, however, including several neutron scattering techniques, data analysis appears to be more an art than exact science, with fit quality to be visually assessed by the experienced eyes, and...Go to contribution page
