        Were prepared with the sleeve opening and closing wedges of pure magnesium and magnesium test system - phosphorus. Phosphorus as an element of a low boiling point (below the melting point of magnesium) had to be trapped in the prepared sample, that can not be evaporated. Naważono 10% by wei

        In March while I was nursing my broken right hand (unfortunate fall on a ski slope, which I attempted to challenge perhaps too ambitiously) our research continued. Few samples were sent away for VSM (Vibrating Sample Magnetometer) examination. This method will allow us to study the magnetic properti

        Main studies carried out during February:

        - microhardness measurements of the melt spun ribbons in the as- cast state and after annealing at different temperatures,
        - preparation of new pentanary alloy,
        - phase composition analysis of quaternary alloys with silicon and copper

        During last 3 months I was trying to find solution in case of silver nanoparticles deposition. Due to hydrophobic properties of titanium dioxide surface, spin caoting deposition isn't very efective. I tried also to mixed coloidal solution with some alcohols to increase wettalbilty or let the dr

        Table above presents all types of bioresorbable magnesium alloys, which were cast in February.
        These alloys were produced in argon atmosphere in 750 C. I also focused my interest on theoretical background of TEM studying Introduction to Conventi

        Among the researches of acidic texture performed on multicrystalline silicon texture some selected wafers were subjected to the production of solar cells. Then optoelectronic parameters (reflectance in the range of 400-1100 nm and the current-voltage characteristics) were examined. I am pleased to a

        In the last month I decided to focus my attention on polyelectrolyte layers internal structure and its influence on physico-chemical properties of the multilayer coating. Therefore I made a literature review and I prepared a series of samples for FTIR (Fourier Transform Infrared Spectroscopy) evalua

        Recently I have spent a lot of time preparing my first paper related to PhD project. I hope it will be published in the 3D Materials Science conference proceedings. Its title is “A Toolbox for Geometric Grain Boundary Characterization” which means I have focused on short description of package of so

        In February, I passed exams of 'Fundamentals of solidification', 'Advanced scanning electron microscopy in materials science' and 'Transmission electron microscopy in materials science'.
        I attended in PAS Seminars:

        This month I took part in a training concerning use of the new WDS equipment. It seems that it will be useful in my PhD work since some X-ray peaks from elements in samples received from IOD overlap and are impossible to be distinguished by EDS. Rest of the month was spent on practicing use of the W

        In February, I focused on improving of my first scientific publication. I wrote about electroeposition of Sn-Zn and Sn-Zn-Mo layers from citrate solutions. I mainly describe the results of voltammetric studies. My paper has been already reviewed. I hope that my publication will be published soon. Th
