In June I was on the coference „Advanced Materials and Technologies AMT 2013” In Kudowa Zdrój. During the conference I presented the part of results of my research (obtained at the firsth and the second year of my studies), in the form of oral presentation entitled a speech entitled „ Electrochemical deposition of tin-zinc alloys from citrate solutions”. Also I listened to several presentations concerning various aspects of materials science.

EMF study of liquid ternary alloys combined with thermodynamic modelling using CALPHAD approach. The partial excess thermodynamic functions for two sets of constatnt ratio of molar fraction was computed in terms of symmetric model, i.e Muggianu, Kohler and Colinet.
Participation at the XLII International Conference on Computer Coupling of Phase Diagram and Thermochemistry held from 26 to 31 May, 2013 at San Sebastian. Poster presentation.
Participation at Gaussian Workshop: "Introduction to Gaussian: Theory and Practice” which held in Wroclaw, Poland from June 24th through 28th, 2013.

From 12th to 14th of June, I attended a workshop dedicated to
analysis of 3D microstructure data obtained mainly from
FIB/SEM dual-beam machines. Most of the time was filled by
a DREAM.3D program tutorial - the tool I've been extensively using
for grain boundary reconstruction, meshing and smoothing.
The workshop took place in Metz and was orginized byl LEM3.

This month I moved one step ahead in my research and elaborated the results of studies concerning HUVECs growth on genipin cross-linked polyelectrolyte coatings. I attempted to improve the cellular adhesion properties of films through chemical cross-linking with a genipin. Hyaluronan (HA), poly-L-lysine (PLL) and alginate (ALG) were used to assemble [PLL-HA]n and [PLL–ALG]n films in two different thickness variants, 12 and 24 bi-layers respectively. The effects of genipin cross-linking on the internal composition, surface topography, nano-hardness of multilayers and as a consequence on cellular processes were investigated. Fourier Transform Infrared Spectroscopy (FTIR) measurements shown a slight changes in the internal structure of multilayers cross-linked with various genipin concentration. Atomic force microscopy (AFM) confirmed that cross-linking affected each of the films topography and stiffness differently. Cellular adhesion, proliferation and functionality studies using endothelial cells, carried out on both films demonstrated differences. The [PLL–ALG]n film was shown to better improve endothelialization, especially for high bi-layer numbers and using higher concentrations of the cross-linker. In May, I participated in “Poznańskie Dni Cytometrii i Immunopatologii “conference, where I presented results of the mesenchymal stem cells differentiation into endothelial cells in order to rebuild tissue structure of porcine scaffolds after acellularization.

In May I focused my activity on writing a paper on a new method
for calculating grain boundary distributions. The new method
uses a concept of metric functions defined in the boundary parameter space.
The first tests showed that our approach
reveals more details comparing with the older method. Our
distributions are also provided with their errors.
Moreover, I received an information that my paper from the last year
conference is finally published.
