Organized by the Institute of Experimental Physics, University of Bialystok and the Institute of Atomic Energy, Swierk under the auspices of the European Crystallographic Association; Committee of Crystallography, the Polish Academy of Sciences; and the Polish Neutron Scattering Society The School is financially supported in part by the International Union of Crystallography; the European Crystallographic Association; the European Office of Aerospace Research & Development; the Ministry of Science and Information Society Technologies; the Warsaw University of Technology; and the University of Bialystok.
		Structural aspects of phase transitions Maciej Kubicki, Poland Topics polymorphism and phase transitions; enantiotropic and monotropic systems; some applications of thermodynamics in crystal chemistry; order of a phase transition; permitted symmetry changes during the phase transition order parameter and its temperature dependence; examples of order parameters examples of second order order - disorder transitions: p-molecular compounds molecular motions and hydrogen bond transformations in 1,3-cyclohexanedione crystals examples of first-order transitions, e.g.: acylurea derivatives 1-phenyl-2-methyl-4-nitro-5-bromoimidazole the changes in electron density and electrostatic potential during the phase transitions: KMnF3
