The influence of the plating regione of bismuth coating onto carbon paste: a microscopic study
Švancara, I. ; Baldrianová, L. ; Vlček, Milan ; Kotzian, P. ; Metelka, R. ; Vytřas, K.
This paper gives the results of the microscopic study of bismuth coatings deposited on carbon paste surface from solutions with different compostition. The observed structures show the impontence of the regime deposition for preparation of bismuth film electrodes for electroanalytical measurements.
The printed electrodes modified by ruthenium oxide and glucose oxidase to determination of hydrogen peroxide with exploitation of the flow analysis
Kotzian, P. ; Brázdilová, P. ; Bartoš, M. ; Švancara, I. ; Frumarová, Božena ; Kalcher, K. ; Vytřas, K.
The paper gives the results of investigation of modified carbon electrodes for constraction of sensor for determination hydrogen penoside and glucose. The carbon in was modified by RuO2 and glucose oxidase .
The microscopic study of bismuth coatings onto a surface of carbon paste electrode. The role of deposition system on properties and behavior bismuth film electrodes
Švancara, I. ; Baldrianová, L. ; Vlček, Milan ; Metelka, R. ; Vytřas, K.
This paper brings the results of microscopic study of bismuth coatings. The coatings were plated onto a carbon paste surface from silicon oil and studied by electron microscopy and EDX microanalysis.
Program a sborník souhrnů
Ulbrich, Karel ; Výprachtický, Drahomír
Proceedings of the 43th Microsymposium of Prague Meetings on Macromolecules, covering various aspects of incorporation of biomimetic structures in synthetic polymers and their surfaces, new advanced biomaterials for biology and medicine. and, vice versa, unique polymers and materials produced using bioanalogous processes and biosynthetic pathways.
Mechanical properties of organic - inorganic nanocomposites coatings
Farkačová, T. ; Bláhová, O. ; Špírková, Milena
The contribution deals with the determination of tribological properties of hybrid organic-inorganic epoxy-based coatings on tribometer by method pin-on-disc. The friction coeffiecient and wear resistance were monitored. Examined specimens were prepared from functionalized organosilicon precursors, oligomeric di- or triamines and colloidal silica particles. The products are the result of two independent reaction mechanisms: the sol-gel process and the epoxy-amine addition reactions.
Gas and vapour permeation through polymeric membranes
Pientka, Zbyněk
The new method for measurement of gases through swollen polymers is described. Results obtained on a homemade instrument are presented, showing that wate-swollen membranes of sulphonated poly(phenylene oxide) have lower permeability than dry membranes.
Behavior of TiO2 in borophosphate glasses
Koudelka, L. ; Mošner, P. ; Pospíšil, J. ; Frumarová, Božena
Structure of borophosphate glasses containing TiO2 were studied Raman spectra this glasses were measured and discused.
Improvement of mechanical properties of thermoelectrical materials by forming
Schindler, I. ; Navrátil, Jiří ; Takagi, S.
Possibillities of improving of mechanical properties of thermoelectrical material by forming were studied and discoussed.
Alternative methods for determination of local tolerance of chemical substances and final products
Kejlová, K. ; Jírová, D. ; Bendová, H. ; Labský, Jiří
An overview is given of alternative local-tolerance tests as used by various laboratories.
