The continuation of the EMF study in liquid ternary alloys.
An assessment of the ternary interaction parmeters for thermodynamic description of the liquid state. Modelling the excess and molar function s in concentration function for the investigated ternary metallic system.

In September, I was at a very nice conference EUROMAT in a very nice place Seville. I presented there a poster titled: Short acidic surface texturization of mc-Si wafers for specific crystallographic orientations and its impact on opto-eletrical parameters of solar cells. During its presentation I gained the first prize :) The greater the joy that I received the award from the hands of Professor Susan Schorr.

This month the zeta potential analysis of HA/Chi multilayer coatings on glass slides with 14 mm x 10 mm size was performed. The pH dependence of zeta potential and the isoelectric point derived there from do not enable a differentiation of the PEM with different terminal layers. Neither does an effect of cross-linking become visible by the zeta potential results. We conclude that an intermixing between adjacent HA and Chi layers at a higher number of polysaccharide bilayers makes the outermost surface indistinguishable in terms of surface functional groups. Such behavior is already reported in the literature for weak polyelectrolytes such as hyaluronic acid or chitosan.

In September I was trying to finish an article
on various methods for identification of symmetric
and quasi-symmetric boundaries.
These studies will complete the previous work
on characterization of tilt and twist boundaries.
Since symmetric boundaries are also used as
reference boundaries in quantitative studies of
boundary networks, efficient
tools are also needed for this class of grain boundaries.

In the end of the last month I was on the internship within the Erasmus programe. The internship was conducted in TUBITAK MAM in Gebze in Turkey.Main topic of this period was organic solar cells : the cell formation technology and addition of matal nanoparticles to the hole transporting layer from PEDOT:PSS. For first we tried 70nm particles solution from ICSC PAS but the results were worse for sample with particles than for reference cell. U to 20% of efficiency enhancement was obtained for gold nanoparticles. But the efficiency increase was caused by the Voc increase rather than photocurrent, which was decreased. Thus we explain this results as a series resistance drop due t the nanoparticles presence
