      • PhD Report (Jan'12) P. Czaja
        30/01/12
        In January with the help of my prominent supervisors, which I have the privilege to work alongside with, we produced ribbons via a melt spinning technique. This method is based on rapid cooling of molten materials leading to quick solidification. There were four ingots prepared with nominal composit

        In Januar,

        New Year has started with application the Miedema and de Boer theory for calculation the formation enthalpies of metallic alloys, for example Fe-Ti. Yielded results was compared with DFT calculation. As is well known, Miedema’s group developed a widely used thermodynamic theory

        13/01/12
        In December, I took into consideration issues concerning methods of physico-chemical polyelectrolyte multilayer coatings characterization. I devoted time for a review of the literature on the use of radial flow test to determine the kinetics of cell adhesion on solid surfaces. I also made several at

      • PhD report (December 2011) K. Stan
        09/01/12
        Main studies carried out during December:

        - analysis of the results obtained so far,
        - casting of new quaternary alloy,
        - microstructure analysis of prepared ingot using SEM,
        - preliminary tensile tests on melt-spun ribbons with molybdenum addition using INSTRON 6025

        09/01/12
        If the title is just 'report', that means that nothing really exciting happened... I have been slowly developing my tools for geometric grain boundary characterization, and collecting ideas for futher work. Hopefully, I should be able to analyze some statistical samples soon. What is more,

      • PhD report (December 2011) J.Poplewska
        05/01/12
        My Research:

        -Processing by ECAP (equal channel angular pressing) a sample of AA1050 three times according to route A.
        -Completion of series of studies with scanning electron microscopy using technique - EBSD (electron backscatter diffraction) - for creating orientation maps (microst

        05/01/12
        In December I performed some Vicker’s hardness test on the last series of composite samples (with submicron AlN reinforcement). It turned out that they have considerably lower hardness than the previous series (with ~1 micron AlN) – about 250 HV. The worse mechanical properties may origin from the

      • Snow drifts of December and lack thereof
        05/01/12
        As December was passing by, and days until delivery of my titanium was freezing away I had the chance to read something more on plastic deformations of metals and KoBo method. Plastic deformation in low temperatures is inevitable tied to development of internal structure, decrease of ductility and i

        In december I studied the complex formation and its stability in Zn(II)-Sn(II)-Mo(VI)-citrate systems by cyclic voltammetry method, in a series of electrolytes with different concentrations of sodium citrate, sodium molybdate, zinc sulfate(IV), and tin sulfate (IV). All electrochemical measurements

        This month I have focused on reading scientific literature, mainly concerning basics of focused ion beams. Additionally, I was trying to do some experiments on the sample received from IOD last month, but I didn’t manage to successfully accomplish any of the trials.
