	The Study of Permeation of Toxic Compounds through Barrier Materials Using Gas Chromatography Brtníková, Jana ; Čáslavský, Josef (referee) ; Večeřa, Zbyněk (referee) ; Friedl, Zdeněk (advisor) Transport phenomenon of gas and vapors through polymer barrier materials as well as the factors affecting permeability of gaseous and liquid toxic compounds were investigated and results are presented in this thesis. Permeation characteristics investigation methods were elaborated and verified with focusing on utilization of gas chromatographic method and its instrumental modifications. Detailed record
	The study of the protective properties of the foil and coatings materials Slováková, Kristína ; Friedl, Zdeněk (referee) ; Obšel, Vladimír (advisor) The report deals with the study of the resistence of the nonporous polymer materiále against permeation of the selected TICs, with the analysis of the running difussion processes and utilization of the acquired results for the selection of suitable barrier materials for the protective means.

	Modification of transmissivity of hydrogen through the surface of Ni3Al by alloying Čermák, Jiří ; Rothová, Věra Hydrogen invasion into Ni3Al-M was studied by gas-permeation method in temperature range 573 - 1 223 K. The dependence of hydrogen permeation flux J(d) through the membrane-like samples on the samples thickness d enabled us to assess the influence of the surface upon the rate of permeation. The surface transmissivity was introduced as a quantitative characteristic describing the rate of the process. Influence of three modifying elements M = Fe, Cr and Zr was studied. It was found that Zr supports and, on the contrary, Cr eliminates the inhibiting effect of the surface. The iron did not alter significantly the hydrogen transmissivity, and it causes enhanced grain boundary brittleness in hydrogen environment. Detailed record
