Strukturní studie tenkých titaničitých vrstev
Šolcová, Olga ; Matějová, Lenka ; Krejčíková, Simona ; Matěj, Z. ; Kužel, R. ; Strýhal, Z.
Our study is focused on the relationship between the number of oxyethylene units in nonionic surfactants used for preparation of a set of various titania layers by dip-coating via the sol-gel method and morphology, roughness, type of titania phase and textural properties of the prepared titania layers. Additionally, the contact angle determination as a rapid and easy method suitable for evaluation of the surface quality of the prepared titania layer has been tested, too.
Příprava a charakterizace dobře definovaných tenkých vrstev oxidů přechodných kovů
Krejčíková, Simona ; Strýhal, Z. ; Pavlík, J. ; Kužel, R. ; Matějová, Lenka ; Šolcová, Olga
The differences in surface morphology, roughness, structural and textural properties of thin nanolayers of Titania that is promising as a catalytic agent e.g. for removing of organic impurities from waste water and air were studied. Special attention was focused on testing of superhydrophilic properties by contact angel measuring.
Syntéza nanotrubiček Ti-NT: vliv modifikace výchozího TiO2 na krystalickou strukturu a morfologii
Králová, Daniela ; Šlouf, Miroslav ; Kužel, R.
This work is focused on preparation of titanate nanotubes (Ti-NT) from various crystalline modifications of TiO2. Different source micro/nanopowders of TiO2 yielded Ti-NT with similar sizes, shapes and structures. Residual TiO2 particles in final Ti-NT suspensions were eliminated by modification of preparation procedure. Morphology and crystalline structure of both source TiO2 and final Ti-NT were investigated by means of electron microscopy, electron diffraction and X-ray diffraction.
Příprava a charakterizace isometrických zlatých nanočástic s předem spočítanou velikosti
Šlouf, Miroslav ; Kužel, R. ; Matěj, Z.
We prepared and characterized Au particles with different sizes in solution by UV/vis spectroscopy and in solid state by TEM and powder diffraction.
