In August I continued the the voltammetric studies and potentiostatic deposition of alloy layers, on the steel and copper surfaces, from stable homogeneous Zn(II)-Mo(VI) citrate baths with various concetrations of sodium citrate and sodium molybdate. Next I summarized all the investigations carried out during last moths and I wrote paper entitled "Investigation of electrochemical co-deposition of zinc and molybdenum from citrate solutions". In this work I state, among others, that it is possible to electrodeposit Zn-Mo alloy layers from the aqueous citrate solutions. I hope my article will be published soon.

Attempts were made to embossing pattern on a copper disc, completed only a partial success. Due to the high melt of the strong deformation pattern is only partially extruded. However, it was discovered the cause of this difficulty - an outside company doing the matrix does not leave room for the flow of the material during deformation, which is why it has failed to do our prototype in a proper manner. In a further step we modify the template and will attempt embossing pattern. However, two discs prepared with outlines of designs. Since the earlier attempt to create a mirror of the first disk failed, perhaps due to the large curvature of the mirror, or due to a small increase in the electron density caused by insufficiently strong deformation, treated steel segment of curvature smaller ball for the second disc bending previously prepared by careful polishing .

While August was dissolving into a distant memory I designed new compositions of my alloys (Ni-Mn-Sn). This is to study the influence of valence electron concentration on martensititic start tarnsformation temperature within a concentration range that seems to be uncharted according to literature. The compositions are set and now all that needs to be done is the casting.

In June I had a two-week research internship at the Wroclaw University of Technology. On the internship I was testing a new alkaline texturing solution based on digestion with KOH and dihydric alcohols. In July, I attended a conference Junior Euromat addressed to students and young researchers. At the conference, I had the opportunity to see the latest developments in the field of materials science.
