Oxides with Perovskite structure are a fascinating class of materials with a huge variety of technological applications, e.g. ion conductors for energy storage and transformation, electrocatalyst, solar cells, magnetism, etc. While the undistorted ABO3 structure shows a simple cubic structure, it turned out recently that many of these compounds present a more complex structure on a local …
Sulfide solid electrolytes pose a high potential for application in all-solid-state batteries while they are compatible with conventional lithium-ion processing technology. Still, some obstacles regarding material degradation need to be overcome. Thus, the proposed project aims to a surface protection and interfacial optimization by ALD-coatings on sulfide-based solid electrolytes (SE) - …
Through fundamental research on structure-property relations, using complementary simulation, spectroscopic and functional characterization methods, we will map the "genome" and develop new active glasses and glass-ceramics with promising applications. For that, the core group of the Center will comprise 13 professors at USP and UFSCar (both located in São Carlos) who are experts in engin…
Titania (TiO2) and niobia (Nb2O5) are important components in commercial glass and glass-ceramic materials. Little is known, however, about the structural role that they play and how the physical properties are affected by the structural organization. A central issue is their chameleon-like nature in that both elements have an ability to transform their structural identity by changing t…
The project aims to prepare and characterize glasses of mixed fluorophosphate systems based on gallium phosphate, with alkali and alkaline earth metal fluorides (MF and MF2), codoped with silver and rare-earth ions to obtain luminescent nanoclusters of silver distributed through the glass matrix through thermal treatment of the samples and also through the laser photostructuring process, …
During the past decades, the incorporation of transition metal oxides into glasses has been the focus of significant attention, owing to their unique linear and non-linear optical properties such additives bestow upon oxide glasses, highlighting their potential of replacing lead as an ingredient in this respect. Little is known about the structural role of the transition metal oxide compo…
Standard and advanced solid-state Nuclear Magnetic Resonance (NMR) methods will be used forelucidating the short- and medium-range order of sodium borosilicate glasses at the atomic level. A special focus of the study will lie on the structural characterization of phase separation processes that have been identified in this system and observed to influence the fracture toughness. The new…
Nuclear Magnetic Resonance (NMR) and electron paramagnetic resonance spectroscopy offer an element-selective, inherently quantitative and experimentally very flexible approach for the structural elucidation of glassy and glass-ceramic materials. NMR can give clear-cut and quantitative answers about the extent of network polymerization, the spatial distribution of the network former and ne…

Nuclear magnetic resonance (NMR) offers element-selective, inherently quantitative and locally selective capabilities, which, combined with the versatile pulse-selective methods, can probe the short- and intermediate-range orders in a broad range of materials, including those in the vitreous state. The query into the structural details comprising transition metal ions incorporation in gla…
The objective of the research project is driven by the quest for structure-function correlations in the area of high-strength calcium aluminosilicate glasses. The student will prepare, characterize and measure key mechanical properties (elastic constants, dynamical mechanical properties, and crack initiation resistances) of glasses and conduct solid-state NMR and Raman spectroscopic exper…
The main goal of this project is the study of ion dynamics in fast sodium ion-conductors for applications as solid electrolytes and electrode materials for improved energy storage capacity and reversibility. Lithium and sodium ion dynamics will be characterized by spin-lattice relaxation and stimulated-echo experiments in NASICON- (Na Super Ion Conductor) and Na5YSi4O12-based glass-cerami…
Rare-earth ion (RE) doped glasses and glass-ceramics are viewed as the new generation of luminescent photonic materials. Besides having superior thermal and mechanical properties than single crystals, these materials can incorporate higher concentrations of doping ions and be fabricated at lower cost, in a larger variety of sizes and shapes. To optimize the luminescent properties of these…
