Investigations of phase transitions in liquid crystals by means of adiabatic scanning calorimetry KU Leuven
High resolution calorimetric techniques have substantially contributed in characterizing and understanding the delicate thermal behaviour near many phase transitions in liquid crystals. In this paper we describe a high-resolution adiabatic scanning calorimetric technique that has proven to be an important tool to discriminate between first-order and second-order phase transitions in addition to render high-resolution information on fluctuations ...
Life at ultralow interfacial tension: wetting, waves and droplets in demixed colloid-polymer mixtures KU Leuven
Mixtures of colloids and polymers display a rich phase behavior, involving colloidal gas (rich in polymer, poor in colloid), colloidal liquid (poor in polymer, rich in colloid) and colloidal crystal phases (poor in polymer, highly ordered colloids). Recently, the colloidal gas-colloidal liquid interface received considerable attention as well. Due to the colloidal length scale the interfacial tension is much lower than in the atomic or molecular ...
Confinement effects on strongly polar alkylcyanobiphenyl liquid crystals probed by dielectric spectroscopy KU Leuven
Dielectric spectroscopy has often been used to study confinement effects in alkylcyanobiphenylliquid crystals. In this paper, we highlight some of the effects that have been discoveredpreviously and add new data and interpretation. Aerosil nanoparticles form a hydrogen bondedrandom porous network. In dispersions of alkylcyanobiphenyls with aerosils, an additional slowprocess arises, that we ascribe to the relaxation of liquid crystal molecules ...
Hyperfine interactions: the past, the present and the future KU Leuven
Five major hyperfine interaction techniques, detected by nuclear radiation, originated in the short time span between 1950 and 1965. The coincidence with the demographic expansion, especially in Europe, of university education led to the creation of many new research laboratories applying these promising techniques in solid state physics, chemistry and biology. Since the turn of century many of the early pioneers are going into retirement, ...
