Freeze casting of hierarchically structured highly porous γ-Al2O3 monoliths

Author(s): Hermina Hudelja (Author), Andraž Kocjan (Supervisor)

Year: 2021

Type: Doctoral dissertation

Highly porous ceramic γ‒Al2O3 monoliths are important in many applications, e.g., catalysis, thermal insulation and adsorption, yet they still have a lot of unrecognized potential. There is a lot of incentive to employ simple and green fabrication processes for the preparation of such porous ceramic materials; however, many challenges, especially …

The hydrolysis of AlN powder and its use for the synthesys of nanostructured alumina coatings

Author(s): Andraž Kocjan (Author), Tomaž Kosmač (Supervisor), Kristoffer Krnel (Co-Supervisor)

Year: 2010

Type: Doctoral dissertation

he thesis describes a study of aluminum nitride (AlN) powder hydrolysis in the temperature range between 5 °C and 90 °C. The analysis of the temperature dependence of the course of the hydrolysis and the reaction kinetics, along with a mechanistic model set up for the hydrolysis reactions, gives a …

Hydrogen absorption in Ti-Zr-Ni alloys

Author(s): Andraž Kocjan (Author), Spomenka Kobe (Supervisor), Paul McGuiness (Co-Supervisor)

Year: 2009

Type: Doctoral dissertation

Our research focused on the formation of Ti40Zr40-xNi20Cux (x=3, 5), Ti45Zr38-xNi17Cux (x=3, 5), Ti53Zr27-xNi20Cux (x=3, 5) and Ti58Zr24-xNi18Cux (x=3, 5) icosahedral (i-phase) quasicrystals by three different techniques and their subsequent characterization and high-pressure hydrogenation. The quasicrystals of this system are thermodynamically stable and they have a relatively good affinity for …
