In August, I continued my investigations of balled-milled powders after different milling periods. I also performed some TEM investigations of compacted ball-milled aluminium powder with magnesium nitride addition hoping to find any evidence of AlN formation during milling/hot pressing of powders but without any luck.

This month I was focused on investigations of tetragonal ZrO2 samples received from AGH. These are preliminary studies carried out to obtain information about measurement parameters that are necessary for successful experiment.

I have obtained first preliminary results of my computer simulations. They were performed using FDTD Solutions of Lumerical. This program uses fine mesh of lattice points in the space and solves Maxwell's equations in ech point. By placing any object and setting light source with distnct monitors program allows to predict saome basic features and behaviors of the model.

First of my task was investigation of various features of different metals in respect to scattering cross section of the incident light. Aluminum, Silver, Gold, Copper and Palladium particles show interesting increase in the different part of the spectrum.

I have also confirmed dependency of Scattering and absorbtion cross section on surrounding refractive index. In case of 120nm silver sphere pick was shifted from 350nm to 670nm when refractive index changed from 0 to 3,5. Additional secondary pick can observed when value of n equals 2,5

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 .
