Tribology of thin wetting films between a bubble and a moving solid surface
S. I. Karakashev, K. W. Stoeckelhuber, R. Tsekov +2
The tribology of a bubble rubbing on a solid surface is studied via interferometry. A unique experimental setup is designed for monitoring the thickness profiles of a wetting film,…
Two-dimensional connective nanostructures of electrodeposited Zn on Au(111) induced by spinodal decomposition
J. Dogel, R. Tsekov, W. Freyland
Phase-formation of surface alloying by spinodal decomposition has been studied for the first time at an electrified interface. For this aim Zn was electrodeposited on Au(111) from…
Experimental proof for resonant diffusion of normal alkanes in LTL and ZSM-12 zeolites
K. Yoo, R. Tsekov, P. G. Smirniotis
The intra-crystalline diffusion of normal alkanes in LTL and ZSM-12 zeolite was experimentally studied via gravimetric measurements performed at different temperatures. A periodic…
A fractal classification of the drainage dynamics in thin liquid films
R. Tsekov, E. Evstatieva
It is demonstrated that the dynamic structure is very important for the rate of drainage of a thin liquid film and it can be effectively taken into account by a dynamic fractal dim…
Surface diffusion control of the photocatalytic oxidation in air/TiO2 heterogeneous reactors
R. Tsekov, E. Evstatieva, P. G. Smirniotis
The diffusion of superoxide radical anions on the surface of TiO2 catalysts is theoretically considered as an important step in the kinetics of photocatalytic oxidation of toxic po…
Theoretical models for NO decomposition in Cu-exchanged zeolites
R. Tsekov, P. G. Smirniotis
A unified description of the catalytic effect of Cu-exchanged zeolites is proposed for the decomposition of NO. A general expression for the rate constant of NO decomposition is ob…
