Abstract: The project reacts to the world wide-spread research in the sphere of nanomaterials and the attention is paid to their application as films in area of material protection. The investigation is focused on inorganic-organic nanocomposite films prepared by „nanobuilding blocks“ process for protection of materials. The resistance to water, corrosion medium and adherence of biofilms is studied. The investigation is also focused on research of the composition-structure-properties relationships of given nanomaterials while the attention is paid to the utilisation of the fundamental theoretical knowledge which can enable to generalisation. The quantification of the composition-structure-properties relationships will be carried out by the modern mathematical-statistical evaluating methods which make possible to create such models which can be applicable for generalisation and prediction.

Abstract: The corrosion of the tableware glass (especially in dishwashing machines in the large gastronomy) and weathering during the storage as well as during the oversea transport is from the actual point of view one of the most important questions of the glass producers economic competition. The main aim of the project is the study of composition – structure – property relationships of oxide glasses leading to the proposal of methodology enabling the prediction of glass resistance against corrosion and weathering. The methodology is established on the set of different glasses, with differences in chemical composition of the surface as well as in the bulk. The differences are justified with respect to thermodynamic modeling, surface tension measurement and surface composition analyses by progressive spectroscopic methods. Such obtained results should be put into correlation with glass corrosion and weathering process.

Abstract: Projekt sa zaoberá vývojom nových sklených a sklokeramických luminiscenčných materiálov na báze Al2O3 a RE2O3 pre aplikácie v LED diódach emitujúcich biele svetlo, najmä materiálov s dobrou emisiou v červenej spektrálnej oblasti s cieľom zvýšiť CRI index doteraz známym luminoforom. Pripravené budú luminiscenčné materiály vo forme sklených mikroguličiek. Preskúmané budú vlastnosti nedopovaných materiálov najmä z pohľadu štruktúry aluminátových skiel v sústave Al2O3 – RE2O3, použitím sprektroskopických metód, termických vlastností a kinetiky kryštalizácie. Optimalizované budú podmienky kryštalizácie skiel s cieľom prípravy sklokeramických materiálov požadovaných vlastností. Detailne preštudované budú fotoluminiscenčné vlastnosti sklených a sklokeramických materiálov dopovaných iónmi vzácnych zemín a prechodných prvkov s cieľom zvýšiť emisiu luminoforov v červenej spektrálnej oblasti. Pozornosť bude venovaná vzťahom medzi luminiscenčnými vlastnosťami pripravených materiálov a ich štruktúrou a morfológiou.

Abstract: Transparentné polykryštalické keramické materiály s luminiscenčnými vlastnosťami predstavujú vďaka lepším mechanickým vlastnostiam a vďaka nižšej cene náhradu za monokryštály pre tuhé lasery a scintilátory. Pre dosiahnutie transparencie vo viditeľnej oblasti je potrebné pripraviť polykryštalický materiál s kompletne eliminovanou pórovitosťou. Pre dosiahnutie kvalitných mechanických vlastností, najmä pevnosti a tvrdosti, ktoré vedú k zvýšeniu odolnosti voči teplotným šokom je potrebné pripraviť materiály s jemnozrnnou, ideálne submikrónovou mikroštruktúrou. To je v protiklade s požiadavkou na odstránenie pórov, vyžadujúcou použitie vysokých teplôt a dlhých časov spekania. Projekt je zameraný na štúdium fundamentálnych aspektov spekania materiálov s kubickou kryštálovou mriežkou, najmä yrito hlinitého granátu, dopovaného opticky aktívnymi prísadami a optimalizáciou parametrov jeho prípravy s cieľom pripraviť transparentné materiály s luminiscenčnými vlastnosťami a výnimočnými mechanickými vlastnosťami.
