MELTING/FREEZING IN NARROW PORES; DIELECTRIC AND EPR STUDIES

We report results of a study of the phenomena associated with melting of nano-phases confined within narrow pores. The study was performed by differential scanning calorimetry, dielectric spectroscopy, nonlinear dielectric effect measurements and electron paramagnetic resonance. Results of theoretical calculations concerning the phenomena are also presented. It has been proved, by experimental and theoretical methods, that the phenomena of melting in nano-phases are accompanied by the appearance of new phases (contact layer phases, hexatic phase), the nature of which depends on the structure of the walls and the pore size. The melting temperatures also depend strongly on these factors.
