Dr. Tadeja Birsa Čelič studied metal-organic porous materials, e.g. crystalline materials built of metal oxide units, which are each connected with organic ligands, in the scope of her doctoral thesis. Their characteristics like an extremely large specific surface area and low density makes these materials very interesting for hydrogen storage, the storage and separation of carbon dioxide and methane, as well as for energy storage.
D.09 Tutoring for postgraduate students
COBISS.SI-ID: 266498048In an invited lecture, the basic concepts of heat storage, with emphasis on the sorption heat storage, were first presented. Then, some examples of the study of heat storage performance in some aluminophosphate and metalorganic porous materials were shown.
B.04 Guest lecture
COBISS.SI-ID: 5184282Two different water sorbent composites, one with disordered mesostructured iron silicate matrix and the other with ordered mesoporous silicate matrix together with calcium chloride were presented. The composites were prepared by wet impregnation of disordered mesoporous iron silicate and ordered mesoporous silicate with aqueous solution of calcium chloride. Structural and water sorption properties of both composites were presented at 5th International Symposium Advanced Micro- and Mesoporous Materials in Varna 2013.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 5314074In an article in the business newspaper with the highest publicity in Slovenia we presented in a simplified manner the field of energy storage, the latest technology and our own worldleading research in this area.
F.18 Transfer of new know-how to direct users (seminars, fora, conferences)
COBISS.SI-ID: 5141786We have studied the hydrothermal stability of three aluminium (MIL-96, MIL-100, MIL-110) and one zinc carboxylates. Among aluminium-based MOFs, MIL-96(Al) and MIL-100(Al) show higher stability in water as the MIL-110(Al) material, which is stable only when water is present in traces. Hydrothermal stabiliy of ZnBTC structure is a rarity for Zn-based MOFs and the reason lay in the presence of hydrogen bonds between adsorbed water and the framework and due to the π-π interactions beetween benzene rings. However, high water resistance even at elevated temperatures together with promising water sorption properties (0.7 g of water per g of material) implies that only MIL-100(Al) material is a potential candidate for water sorption based energy applications.
