Atomic-level characterization of metal/oxide interfaces (Ti, Fe, Ni, Ag, Au/Al2O3, MgO, TiO2): a background for nanomaterial design for catalysis to photonics

Khubezhov S.A., Silaev I.V., Bliev A.P., Kibizov D.D., Grigorkina G.S., Kozyrev E.N., Askerov R.O., Goncharov I.N., Sekiba D., Ogura S., Fukutani K., Magkoev T.T., North Ossetian State University, RU

Corresponding author, e-mail: t_magkoev@mail.ru (Tamerlan Magkoev) Metal/oxide systems are widely used in different application fields, such as heterogeneous catalysis, nanoelectronics, sensing techniques, optics, photonics, etc. [1]. Despite of a very extensive research in this field, [...]

Surface Characterization of Nanoparticle Coated Paperboard

Stepien M., Saarinen J.J., Teisala H., Tuominen M., Aromaa M., Kuusipalo J., Mäkelä J.M., Toivakka M., Abo Akademi University, FI

Both surface topographical and chemical composition of nanoparticle coated paperboard was characterized to explain observed differences in surface wettability. TiO2 particles induce superhydrophobicity with water contact angle (CA) of 161° whereas SiO2 particles result in [...]

In-situ Surface Characterization of Nano- and Microparticles by Optical Second Harmonic Generation

Schürer B., Wunderlich S., Peschel U., Peukert W., University of Erlangen-Nuremberg, DE

We use optical Second Harmonic Generation (SHG) to probe different kinds of surface properties of dispersed particle systems in in-situ and in real time. Examples for applications are the direct study of molecular adsorption at [...]

Nanoscale hydrophobic coatings for the separation of liquid mixtures

Truman P., Frenzel R., Longari N., Uhlmann P., Stamm M., Institute of Polymer Research, DE

Organofunctional nanoscale silane coatings are widely used to modify surface chemistry. Such coatings have many applications in micro- and nanofluidics because liquid motion on these scales is strongly influenced by capillary or wall effects. In [...]
