In case of Layer by Layer method of silver nanoparticles deposition, druring last month I confinred the deoposition condition.
As preliminary cleaning and activation of the polished silicon substrates the mixture of sulfuric acid and hydrogen peryoxide (2:1 vol.) was used.
Polyelectrolyte solution was 500ppm PAH solution. Variuos ionic strength of solution were tested. (1e-4, 1e-3,1e-2 and 0,15M addjusted with sodium chloride)
The highest ionic strength resulted in highest nanopartices concetration.
Also comparison beteewn PAH and PLL were performed. The test indicated that PAH is a better choice.

My work with simulation software were concentrated on modiffication of the model and the script code which enables me in the future investigation of absorption enhancement in silicon with metalic nanoparticles.

In February I took papers and covered up with my blanket. I spent winter evenings sitting close to the heater with a cup of cacao. Page by page I traversed methodology of silver and gold nanoparticles formation in PEMs. Finally I found the best solution and performed some successful experiments. I have also started proteins adsorption trial.

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.
