It is possible to show on EBSD map projections of vectors normal to the common plane twin 102. Moreover, for a number of selected grains pole figures were prepared: on your own system, TSL and HKL. We can see that:
1. The limits of Twin are very well defined and the directions normal to the planes are generally perpendicular to the grain boundaries
2. Directions are displayed correctly because it agrees with the figures pole 102
3. My program corresponds to the convention TSL (x-down, y-right), working with HKLem requires caution
Keep in mind that if we want to apply the criterion described geometry of the border, there is no way to manipulate orientations gathered by EDAX system by changing the sample:

To determine the boundaries of applied algorithm, which recognize the grain due to the consistency of orientation. Then, as highlighted objects have been extended through translation unit in two independent directions. Created incidence matrix grains, and the boundaries were determined by multiplying the expanded neighboring grains. On the map the boundaries of tolerance dezorientacjach 10 ° angle for ideal angle of 60 ° and 10 ° axis tolerance for the ideal axis 111.

This month was a final step in dissertation writing. Described results might be fundamental for modern type of tissue analog preparation.Migration channels in form of straight lines obtained in ablation process provided the control of smooth muscle cells migration and spreading, mimicking their organization in blood vessel‘s wall. Poly-L-lysine/hyaluronic acid (PLL/HA) coatings cross-linked by carbodiimide or modified by silicon carbide nanoparticles introduction could be the most promising for surface functionalization of cardiovascular devices. Biomimetic multiscale surface functionalization of polyurethane/vinyl polychloride base materials improved their bio(hemo)compatibility. Presented results confirmed that significant improvement of blood contacting materials could be possible by fabrication of the multilayer structure mimicking the natural blood vessel‘s wall. The dissertation presented also a new approach in biomaterials hemocompatibility evaluation which seemed to be promising and would be developed in further experimental work.

My dissertation was sent to the reviewers. There is no more chance to improve the manuscript.
I'm waiting for their comments.

In this month I investigated formation of silver nanoparticles using metal island film technique. Four layers having thicknesses of 7, 10, 15 and 20 nm were sputtered at a rate of 2 A / s on polished Si wafers. . The deposited layer thickness was read on a quartz microbalance. The resulting silver layer was then subjected to annealing on the stage heating at 250 ° C under argon for 0.5 hours. The formated islands were analyzed using SEM and AFM. Average size obtained from 7 and 10 nm layers was 60 and 105 nm. For thicker layers islands lost thier oval shape and became irregular. Surface coverage was 46, 30, 29 and 33.8 %, respectively for increasing initial layer thickness.
The obtained structere can be applied to the Si cell as a plasmonic back reflector.
