This month I spent in writing the dissertation, but also managed to make a few AFM maps. It turns out that what is recommended not always is the best. Better than a standard probe FESPA dedicated to silicon was a harder one and that is what I'm going to continue my research.

Dear all, last month was full of surprises - unfortunately not good ones. I have spent almost half of the month on sample preparation (thin foils) using diffrent electrolytes without success. It was for alloys with high amount of Ca. In the end of month I have found a solution - but let me keep this as a secret. We all know that 'know how' is very expensive these days.

My paper entitled „ Tin–zinc alloy electrodeposition from aqueous citrate baths” is already available at http://dx.doi.org/10.1016/j.surfcoat.2013.12.046

In December The utilization characteristics to describe the selection of variants of twinning in the magnesium alloy AZ31 . On the basis of orientation maps are currently suitable algorithms that enable the calculation of how much and what share of the twins at the turn of micro-section created by rotation around the respective crystallographic axis a_i an angle of 86 degrees for the twinning { 10-12 } < 10-11 > and 56 degrees for twinning { 10 -11 } < 10-1-2 > . In the case of twinning { 10-12 } < 10-11 > , we can distinguish the following six options : (10-12) [ -1011 ] (01-12 ) [ 0-111 ] ( -1102 ) [ 1-101 ] ( -1012 ) [ 10-11 ] , ( 0-112 ) [ 01-11 ] and ( 1-102 ) [ -1101 ] . These variants can be obtained from the mother through the appropriate orientation of the rotation counter-clockwise by an angle of 86 degrees relative to the crystallographic axis following : a2 ,- a1 , a3 -a2 , a1 - a3 . By choosing an appropriate subset of the set of symmetry operators for hexagonal networks ( permutation of {9 , 7, 4, 2 , 1, 6} in the standard set of these operators ) is multiplied sixfold unit vector { 1,0,0 } crystallite by a left multiplication by the operator and another multiplication by the transpose of the matrix orientation g due to the expression of this system versor sample. The creation of the twin orientation is carried out by calculating the rotation around the active matrix crystallite versors propagated , and then recombining it and multiplying by the matrix of left-sided g is due to the fact that if f : C' - > C , and g : S- > C, gf ^ T : S- > C ' .
