Vývoj fázové struktury při toku polymerních směsí
Fortelný, Ivan
State of art in description of the phase structure development in flowing polymer blends is discussed. It is shown that the rule satisfactorily predicting a type of the phase structure does not exist. Graphic solution of the equation describing dynamic equilibrium between the droplet breakup and coalescence provides satisfactorily prediction of the dependence of average droplet size on system parameters.
Inorganic cements based on siloxo-sialate structure
Steinerová, Michaela
A summary of an investigation on geopolymers, inorganic cements based on aluminosilicates, whose alkali-activated setting leads to a solid product of siloxo structure. The experimental work on sticking and cementing rocks is evalued by optical microscopy.
Iontově vodivé PMMA gelové elektrolyty
Vondrák, Jiří ; Reiter, Jakub ; Velická, Jana ; Klápště, Břetislav ; Sedlaříková, M. ; Tretera, M.
New polymer gel electrolytes were prepared by in-situ polymerisation. As an optical part inorganic and/or organic compounds can be used, which determines chemical and optical properties of the gel.
Specifická vodivost gelových elektrolytů na bázi PMMA obsahujících lithné soli
Nováček, T. ; Vondrák, Jiří ; Sedlaříková, M.
A subject of our research was measurement of the specific electric conductivity of PMMA based gel electrolytes.
Elektrochemické redoxní procesy v PMMA gelových elektrolytech - chování redoxního páru ferrocen/ferricinium
Reiter, Jakub ; Vondrák, Jiří ; Velická, Jana ; Klápště, Břetislav ; Sedlaříková, M. ; Mička, Z.
Electrochemical behaviour of ferrocene-ferricinium redox couple was investigated in the medium of PMMA gel electrolyte and propylene carbonate-methylmethacrylate liquid.
Elektrolytické vylučování kovových vrstev z aprotických elektrolytů
Dočkal, M. ; Sedlaříková, M. ; Vondrák, Jiří
Uniform layers of various metals were prepared by electrodeposition from PMMA aprotic electrolytes and the layer structure was studied using electrochemical and optical methods.
Lithiové baterie
Nečesal, P. ; Vondrák, Jiří
New materials based on lithium-cobalt oxides were prepared by low-temperature deposition and their application in lithium-ion batteries was studied.
Elektrochemické redoxní procesy v PMMA gelových elektrolytech
Vondrák, Jiří ; Reiter, Jakub ; Velická, Jana ; Klápště, Břetislav ; Sedlaříková, M.
Electrochemical investigation of polymer gel electrolytes based on PMMA with embedded aprotic solvent (propylene carbonate) includes conductivity measurements and cyclic voltammetry [1, 2].
Solid-state referentní elektroda na bázi PMMA
Reiter, Jakub ; Vondrák, Jiří ; Opekar, F. ; Velická, Jana
Electrochemical measurements in polymer gel electrolytes require a reference system, which does not contain liquid electrolyte. New reference electrode based on PMMA-Cd-Cd2+ system was succesfully tested for this measurements.
Inorganic Supports - Preparation and Characterization
Juristová, K. ; Andertová, J. ; Zikánová, Arlette
Commercialize membrane applications have been strongly or exclusively dominated by polymer membranes. Inorganic membranes are made for its following strong points: a relatively high thermal stability, a relatively high chemical stability and biocompatibility of specific materials and good erosin resistance and non-compatibility under high pressure.
