My publication in Electrochimica Acta, titled „Investigation of electrochemical co-deposition of zinc and molybdenum from citrate solutions” is already available online at http://dx.doi.org/10.1016/j.electacta.2012.12.140,

This method is based on photocatalytic properties of titanium dioxide. The UV photon creats electron hole pair. This electron can reduce the silver cation which then deposits on titanium dioxide substrate. At first this method was used for creation of homogenius silver layer with well controlled thickness. First results and literature announcements showed that in the first stage this proces leads directly to nanoparticles deposition.

In my experiment the source of light was 405nm laser. Silver atoms came from a few solutions: 1) solution used previously for electroless deposition, 2)succinimide, 3)solution of silver nitrate.

Obtained microstructure was 0,5um squares, below 20nm particles with nanorods and about 70nm particles respectively for mentioned solutions.

Silver nitrate was the best solution and it was chosen for next research.

There is is an issue with results reccurence.

On 3-4 December 2012, I participated in a meeting Join PhD Seminar, which was attended by PhD students from the Institute of Metallurgy and Materials Science and Enano group belonging to Institute of Materials Science of Technical University of Dresden. The whole meeting was held in Radeburg. It was the first meeting organized by those two institutes. Each of the participants presented the achievements in his researches connecting with doctoral thesis. The topic of my presentation was "Wet chemical surface of crystalline silicon texturisation for photovoltaics."
On 5-6 December 2012 I participated in the Nano-scale and Advanced Materials Characterization Techniques training organized by the Deutsche Gesellschaft für Materialkunde eV, supported by the Dresden Fraunhofer Cluster Nanoanalysis (DFCNA) and The Federation of European Materials Societies (FEMS). The training was devoted to nanostructural researches in materials science and engineering. Analytical high-resolution techniques are important for the new nanotechnology and thin film technology. Nanoanalyze is increasingly necessary for the correct characterization of nanostructured materials in the production, as well as for understanding the nanostructure of materials. Specific use of the available methods shows that often a combination of several techniques of analysis is necessary to ensure that both the process control in nanotechnology, as well as the performance and reliability of new products. Many new developments in the field of imaging and nanoanalyze allows structural and chemical characteristics of <100 nm, up to atomic dimensions.

Eureka! Finally I did solve the problems (mentioned last time) related to coordinate systems. I am now able to get proper sets of parameters of grain boundaries and, using my program, obtain correct distributions of boundaries. I moved on to work on improvments of the methods of calculating the distributions, we believie it can be done better comparing to how it is usually done. I can now focus on the main and the most interesting issues related to my work.

My activities in December:

In December I participated in „Joint PhD Semiar – Enano group from Institute for Materials Science of Technical University Dresden and Institute of Metallurgy and Materials Science of the Polish Academy of Sciences”, which was held in Radeburg: 3-4 December 2012. During the same month I also participated in workshop: „Nano-scale Materials and Advanced CharacterizationTechniques” in Dresden 5-6 December 2012.
