Microscopic and structural characterization of high velocity oxygen-flue and atmospheric plasma sprayed coatings
Murafa, Nataliya; Štengl, Václav; Ctibor, Pavel; Houšková, Vendula
2009 - English
TiO2 nano-powders were agglomerated by a spray drying process for applying to thermal spraying High Velocity Oxygen-Fuel (HVOF) and Atmospheric Plasma Spraying (APS) were used to deposit porous partially nanostructured TiO2 coatings Steel substrate was used for a coatings spraying Scanning Electron Microscopy (SEM), and X-Ray diffraction were performed to study the morphology and the crystalline phases of the titania coatings

Aprotic gel polymer electrolytes
Vondrák, Jiří; Sedlaříková, M.; Krejza, O.
2008 - English
The systematic research of gel polymer electrolytes started in the days of 1st and 2nd Lithium Battery Meetings in Italy. The idea was rather unique - to "thicken" an aprotic solution of lithium sall with an inert polymer. Aprotické gelové polymerní elektrolyty.

The electrochemical redox processes in methacrylate-based polymer electrolytes – study on microelectrodes
Nádherná, Martina; Reiter, Jakub
2008 - English
In our recent project we have investigated electrochemical behaviour of ferrocene in liquid and polymer aprotic electrolytes using various electrochemical methods. The apparent diffusion coefficients were determined for propylene carbonate and poly(ethyl methacrylate)-propylene carbonate medium. Thank to optimised electrolyte composition, the polymerisation lowers the mobility of ferrocene only by 15 – 50 times contrary to previously studied PMMA-PC (Superacryl-based) electrolytes, where approx. three order decrease of diffusion coefficients was found. V tomto projektu jsme studovali elektrochemické chování ferrocenu v kapalných a v polymerních aprotických elektrolytech s využitím různých elektrochemickým metod. Hodnoty difúzních koeficientů ferrocenu byly stanoveny pro propylenkarbonát a pro polymerní elektrolyt poly(ethyl methakrylát)-propylen karbonát. Díky optimalizaci složení elektrolytu, polymerizace snížila mobilitu ferrocenu jen 15 – 50krát ve srovnání s dříve používaným PMMA-PC elektrolytem (na bázi Superakrylu), kde byl pokles difúzního koeficientu asi o tři řády.
