Abstract
U istraživačkom dijelu nanočestice cerijeva oksida su sintetizirane i karakterizirane XRD-om, transmisijskom elektronskom mikroskopijom, dinamičkim raspršenjem svjetlosti, detekcijom naboja čestica i mjerenjem elektrokinetičkog potencijala. Elektrokinetičkim mjerenjima i dinamičkim raspršenjem svjetlosti karakterizirane su i nanočestice cerijeva oksida nakon adsorpcije jakog polielektrolita, poli(natrijeva 4-stirensulfonata). Za interpretaciju adsorpcije polielektrolita na nanočestice u vodenoj otopini primijenjen je modificirani Ohshimin model. Konačno, određeni su adsorpcijski parametri i to gustoća naboja sloja polielektrolita, elektroforetska mekoća i adsorpcijska gustoća za navedeni sustav. U metodičkom dijelu rada pod naslovom „Galvanski članak – primjer dobre nastavne prakse“ izrađena je metodičko-didaktička priprema za učenike trećeg razreda gimnazije. Metodička priprema je temeljena na obrazovnim ishodima, najčešćim učeničkim krivim shvaćanjima, te na uvidu u relevantnu literaturu. Pripremljeni materijal namijenjen je za obrazovnu strategiju učenja otkrivanjem. (80 stranica, 31 slika, 10
Abstract (english)
In the research section cerium oxide nanoparticles were synthesized and characterized by means of XRD, transmission electron microscopy, dynamic light scattering, particle charge and electrokinetic potential measurements. Electrokinetic and dynamic light scattering measurements have been used also to characterize cerium oxide nanoparticles after adsorption of a strong polyelectrolyte, poly(sodium 4-styrenesulfonate). For the interpretation of polyelectrolyte adsorption on nanoparticles in aqueous solution the modified Ohshima model was used. Finally, the adsorption parameters such as charge density of the polyelectrolyte layer, electrophoretic softness and adsorption density were determined. In the methodological part under the title "Galvanic cell – an example of good teaching practice" a didactic-methodological preparation was made for third year high school students. The methodological preparation is based on the educational outcomes, the most common student misconceptions and with the insight into relevant literature. The prepared material is intended for educational strategy of learning by discovery.
