Still working to make my thesis perfect. Moreover, some photoluminescence maps have been done. Unfortunately, texturing influence the defects formation or indicate them. It means that after texturing the quality of the silicon material is worse. That is the effect of minority carrier lifetime which is poor. Not always the best reflectance reduction leads to the best solar cells. This is alway a compromise between the opto-electronic properties.
The second problem is the nanoporous layer removal. Some simulations in FDTD and real reflectance measurements were performed.

In February, I received great new that my paper "On identification
of symmetric and improperly quasi-symmetric grain boundaries"
has been accepted for publication in Journal of Applied Crystallography.
Moreover, I was working on analysis of two grain boundary datasets
of the same IN100 alloy. They differ in sizes: one has about 2000 grains,
while the second has about 9000 grains. This allows to understand
some artifacts of poor statistics.

Thins month I completed writing an introduction, genesis, material and mathods in my PhD thesis entitled: "Role of low-angle boundaries in microstructure and texture transformations during annealing of severely deformed aluminum alloys"

I made analysis of changes of Intensities and Volume fraction of selected texture components during the recrystallization progress for pure aluminium alloy.
I prepared the samples to the plain stress compression as well.

Last month we started investigations of new batch of KoBo deformed zinc along with zinc deformed conventionally. For each method two types of initial material with different history have been used. This way influence of method and type of starting material microstructure on final properties can be investigated and compared. Samples for EBSD were prepared as usual, by mechanical grinding and then mechanicall and electrolyticall polishing.
First sample had lots of twins in its microstructure, therefore we decided to repeat the preparation this time using nitric acid etching to remove layers of deformed grains before the polishing. Remaining samples did not contain any visible twins, so they were investigated in original state.

The FIB gun is working again!
After about 3 months brake I can continue my research. I investigated a series of four YSZ samples this month. Samples differed by the sintering temperature. I am going to check who the grain boundary geometries look like in those sinters. Additionally, I was improving the graphical part of my PhD thesis.
