nanodelci (“core-shell”) imajo fizikalne in kemijske lastnosti, ki
se razlikujejo od lastnosti jedrnih delcev in prevleke in s spreminjanjem
razmerja med prevleko in jedrom lahko dosežemo zelo specifične lastnosti
materiala. Med sintezo v raztopini prevleka raste na jedrnem delcu, ko
koncentracija reagenta preseže mejo nasičenja. V predavanju bodo predstavljeni
primeri sinteze nanodelcev perovskitnih oksidov (BaTiO3 in CeO2) z gradientno
strukturo in sinteze nanotrakov v raztopinah. Predstavljeni bodo ključni
parametri priprave oplaščenih nanodelcev, mikrostrukture in funkcijske
lastnosti materialov, pripravljenih iz takih delcev.<o:p></o:p></span></font></p>

materials to produce core-shell structures allows modification and tailoring of
physical and chemical properties of core materials depending on synthesis
conditions. The composition of the core and shells can thus be varied to
give a wide range of different properties. Furthermore, core-shell
nanoparticles are expected to have unique properties that are not originally
present in either core or shell materials, which makes this procedure an active
area of research. The surface layer can be grown directly on the core particles
once the system is supersaturated with respect to the coating material. This
approach was applied in case of a few types of functional oxides: <o:p></o:p></span></font></p>
