Abstract
V diplomskem delu smo preučevali zgodnje faze rasti srebrnih nanospiral ter vpliv 3-merkaptopropionske kisline (MPA) in vodikovega peroksida (H$_2$O$_2$) na njihovo rast. Z izvajanjem poskusov pri različnih molskih razmerjih $\frac{n(MPA)}{n(Ag)}$ in njihovo analizo na vrstičnem elektronskem mikroskopu (SEM) smo kot optimalno razmerje za rast srebrnih nanospiral določili razmerje 0,01. V naslednjem koraku smo za to razmerje preučevali vpliv dodanega H$_2$O$_2$ s pomočjo analize na elektronski difrakciji in rekonstrukcije recipročnega prostora, kjer smo opazili razpotegnjenost difrakcijskih peg v loke. To potrjuje ukrivljanje kristalnih ravnin in rotacijo kristalne rešetke med rastjo nanospiral.

Title:Study of the early growth stages of silver nano spirals
Abstract:
The purpose of this study was to investigate the early stages of silver nano spiral growth and the influence of 3-mercaptopropionic acid (MPA) and hydrogen peroxide (H$_2$O$_2$) on their growth. By conducting experiments at various molar ratios $\frac{n(MPA)}{n(Ag)}$ and analyzing them using a scanning electron microscope (SEM), we determined the optimal ratio for silver nano spiral growth to be 0.01. In the next step, we studied the effect of added H$_2$O$_2$ at this ratio using electron diffraction analysis and reciprocal space reconstruction, where we observed the elongation of diffraction spots into arcs. This confirms the bending of crystal planes and the rotation of the crystal lattice during the growth of the nano spirals.

Keywords:silver nano spirals, early growth stages, curvature, influence of MPA, influence of H$_2$O$_2$
