Microstructural control is a key aspect in producing ceramics with tailored properties and is often achieved by using dopants in a rather empirical fashion. Atomic scale simulations could provide much needed insight but the long-standing challenge of linki ...
Over the last century, the constant quest to improve the mechanical properties of ceramics has ultimately led to the appearance and production of transparent ceramics. Indeed, microstructural refinement and reduction of the residual porosity after sinterin ...
Despite many years of intensive research there still remain many unresolved questions in powder and ceramic technology. A majority of these issues are linked to interfacial phenomena of atomic scale origin, which makes their experimental investigation very ...
Ferroelectric ceramic – polymer composites have a unique mix of electrical and mechanical properties. Piezoelectric and pyroelectric activity, a wide range of dielectric constants and high breakdown strength are combined with mechanical flexibility, formab ...
This dissertation addresses the development of a Solid Freeform Fabrication process, Selective Laser Pyrolysis, to fabricate three-dimensional porous ceramic preforms from ceramic powders and preceramic polymers. It contributes to a better understanding of ...
An approach combining microstructural and optical modeling based on atomistic simulation results is proposed, in order to assess the performance of Nd:YAG laser ceramics resulting rom luminescence and transparency changes as a function of grain size and do ...
Pore-free composites combining alumina particles within a matrix of pure aluminium are produced by pressure infiltration, varying systematically the degree of the contiguity, beta, of the ceramic phase by sintering prior to infiltration. The thermal expans ...
Efficient light management is one of the key issues in modern energy conversion systems, be it to collect optical power or to redistribute light generated by high power light emitters. This thesis touches mainly on the subject of efficient light redistribu ...
Besides 'bulk' structural and functional ceramic, a third interesting group of inorganic or ceramic materials exists: particles used for medical applications like contrast agent as building blocks for photonic crystals, as thin or thick layers with control ...
