Polimerni nanokompoziti na osnovi biološko ustreznih polimerov in nanožic molibdenovih oksidov
Urška Gradišar Centa, Maja Remškar
Doktorska disertacija
Oznake: molibdenovi oksidi;nanožice;polimerni nanokompoziti;površinske lastnosti;elektropredena nanovlakna;protimikrobna aktivnost;
Inficirane kontaktne površine predstavljajo enega od ključnih vzrokov za širjenje okužb. Biocidna sredstva za zdravljenje okužb, kot so antibiotiki, izgubljajo svojo učinkovitost zaradi razvoja antibiotske odpornosti mikroorganizmov. Za veliko različnih nanomaterialov kovinskih oksidov, kot so ZnO, ...

Izvirni znanstveni članek
Oznake: polimerna mešanica;mehanske lastnosti;kristalizacija;polymer blend;mechanical properties;crystallization;
In this research, the influences of the addition of PVP to PVDF-HFP polymers and the preparation of thin films using a solvent casting method were studied. The PVDF-HFP and polymer blend PVDF-HFP/PVP thin films with a nanostructured surface were investigated using scanning electron microscopy, diffe ...

Correlating mechanical and rheological filament properties to processability and quality of 3D printed tablets using multiple linear regression
Klemen Kreft, Zoran Lavrič, Urška Gradišar Centa, Mohor Mihelčič, Lidija Slemenik Perše, Rok Dreu
Izvirni znanstveni članek
Oznake: fused deposition modelling;personalized medicine;multiple linear regression;tablet quality attributes;correlation;3D printing;
Filament formulation for FDM is a challenging and time-consuming process. Several pharmaceutical polymers are not feedable on their own. Due to inadequate filament formulation, 3D printed tablets can also exhibit poor uniformity of tablet attributes. To better understand filament formulation process ...

Polyisobutylene (PIB) is commonly used as a primary sealant in multi-layer insulating glazing elements, where temperatures often exceed 100 °C. At such conditions, PIB undergoes structural changes, causing different relaxation dynamics and leading to decreased lifetime of the material. Understanding ...
