Abstract:
Sonokemija je definirana kot področje kemije, kjer kemijske reakcije potekajo pod vplivom ultrazvoka, zaradi zvočne energije. Ultrazvok je s povezanimi pojavi znan že več kot eno stoletje, njegova uporaba pa dosega še večji razcvet v današnjih časih. Danes se veliko znanstvenikov ukvarja s tem področjem raziskovanja saj je dokaj inovativna stvar za stimulacijo kemijskih reakcij. Naše raziskave so temeljile na sintezah nanokristalov indijevih in galijevih sulfidov s sonokemijsko metodo. Namen raziskave je bil sintetizirati nanodelce s spreminjanjem vrste topila za indij in galij in s spreminjanjem množinskega razmerja med virom indija in virom galija. Ta metoda se je pri sintezah pokazala kot uporabna, saj smo kot produkt dobili nanokristalinične materiale. Pri sintezah smo uporabili direktno imerzijsko ultrazvočno sondo VibraCell. Dobljene produkte smo karakterizirali z rentgentsko praškovno difrakcijo (XRD), karakterizirali pa smo jih tudi z termičnogravimetrično analizo (TGA) . Za doseg optimalnih pogojev, smo spreminjali različne parametre, npr. vir galija, vir indija, vir žvepla, topilo, atmosfero in čas obsevanja.

Title:
SONOCHEMICAL SYNTHESIS AND CHARACTERIZATION OF INDIUM AND GALLIUM SULFIDES
Abstract:
Sonochemistry is defined as the area of chemistry, in which chemical reactions take place under the influence of ultrasound, due to acoustic energy. Ultrasound is a related phenomenon that has been known for more than a century, its use achieves an even bigger boom in this day and age. Today, many scientists are involved in this research field since it is fairly innovative method to stimulate chemical reactions. Our research is based on the synthesis of nano-crystals of indium and gallium sulphide by sonochemical method. The purpose of the research was to synthesize nanoparticles with varying types of solvents for indium and gallium, and by changing the molar ratio between the source of indium and gallium source. This method of the synthesis proved useful because we obtained nanocrystalline materials as a result. For the synthesis we used the direct immersion ultrasonic probe VibraCell. The resulting products were characterized by X-Ray poeder diffraction (XRD) and also by thermal analysis (TGA). In order to achieve optimal conditions were changing various parameters, for example. the precursor of gallium, indium precursor, precursor of sulfur, the solvent, the atmosphere and the time of irradiation.
