Exploration of the Fe-W-O system for magnetism and photo(electro) chemistry

Granting Departments:	University of Caen Normandy Department of Inorganic Chemistry
Supervisor:	prof. Dr. Ing. David Sedmidubský

Annotation

The aim of this study is to capitalize on the richness of the crystalline, magnetic and electronic structures and photocatalytic properties of W-based oxides by investigating the Fe-W-O system. It is proposed to focus on Fe₂WO₆ as it crystallizes in three different structures exhibiting different transport and magnetic properties. It is of interest to study the thermodynamic conditions in this area of the ternary diagram Fe-W-O to monitor and optimize precise composition and synthesis conditions. Structures and microstructures will be studied by suitable diffraction methods and microscopies. Compounds will be characterized by measuring their magnetic and electrical properties; those with suitable bandgap will also be tested for photocatalytic or photoelectrochemical properties relevant to catalytic degradation of organic pollutants, water splitting or photovoltaic cells.

Study of the crucible-less technologies utilization in the nanostructuring of noble metal particles in glass and glass-ceramics

Granting Departments:	University of Orleans Department of Inorganic Chemistry
Supervisor:	doc. Ing. Pavla Nekvindová, Ph.D.

Annotation

The work is focused on experimental research of the preparation and properties of transparent inorganic materials containing noble metal nanoparticles. We will study the formation, shape and distribution of Cu, Ag and Au nanoparticles in multicomponent inorganic glasses of different compositions. During the work, nanocomposites will be prepared by conventional melt-quenching followed by recrystallization by controlled heat treatment, by ion implantation in collaboration with the CAS or using the aerodynamic levitation method in collaboration with the University of Orléans and the CEMHTI laboratories (Conditions Extrêmes et Matériaux: Haute Température et Irradiation), which are part of the CNRS (Centre National de la Recherche Scientifique). We will evaluate the influence of the structure and composition of nanocomposites on the optical properties (mainly absorption) and color of glasses. The obtained results will lead to a general understanding of the formation of colored metal centers in inorganic nanocomposites and a general solution to the influence of the structure and composition of nanocomposites on optical properties. Aim: To prepare transparent colored nanocomposites containing metal particles. To determine the areas of chemical and thermal stability of nanoparticles in the prepared nanocomposites. To evaluate the influence of structure and composition of nanocomposites especially on absorption properties.

Transparent ceramics for optical applications synthetized by pressure- or vacuum-assisted sintering methods

Granting Departments:	University of Caen Normandy Department of Inorganic Chemistry
Supervisor:	doc. Ing. Kateřina Rubešová, Ph.D.

Annotation

Transparent ceramics can compete with single crystalline materials not only in the stage of research and development but also in the final application. The thesis will be focused on the synthesis of oxide ceramics applicable in the laser or LED field, or utilizable at the detection of ionizing radiation. Spark plasma sintering (SPS) or vacuum sintering will be used for the processing of precursor powders whose optimal crystallinity and microstructure will be also the task of the thesis.
