Controlled crystallization of certain glasses leads to meso-structured materials denominated glass-ceramics (GCs), which consist of nano or microcrystals dispersed in a residual glass. GCs take advantage of desirable attributes from glasses and ceramics and have numerous applications, e.g., in architecture, medical implants, and cell phone displays. However, the susceptibility of GCs to s…
Entropy S is an extensive thermodynamic property proposed by Clausius in 1850 and is one of the fundamental concepts of matter. On the other hand, glasses - materials with high entropy compared to their crystalline counterparts - correspond to a state outside the thermodynamic and non-crystalline equilibrium of matter, as defined by Zanotto and Mauro (2017), and still pose numerous fundam…
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…

This project is focused on detailed numerical simulations of the effect of step-wise relaxation process on the nucleation of crystalline phases in glass or a supercooled glass-forming liquid. The parameters of the relaxation and crystallization processes - number and duration of relaxation steps, the distribution function of the number of crystals per unit volume, N(t) curves, partial ste…
This project is focused on detailed numerical simulations of the effect of composition and relaxation process on the nucleation of crystalline phases in supercooled glass-forming liquids. The parameters of the crystallization process - the distribution function of the number of crystals per unit volume, N(t) curves, steady-state nucleation rates and time-lags - will be simulated and compa…
This project aims at exploring heating rate effects in crystal nucleation of glasses. Experiments are proposed in which defined heating rates will be used. Crystal number densities, nucleation rates and final microstructure of glass-ceramics resulting from these heat treatments will be measured. A systematic change in the heating rate allows for a correlation between these parameters from…

Bone cancer is a neoplasia with high incidence, usually treated through surgery. Conventional therapies such as chemotherapy and radiotherapy are applied to eliminate residual malignant cells; however, these treatments cause significant side effects, motivating the search for safer and more effective alternatives. Among emerging approaches, magnetic hyperthermia stands out, as it employs …
Structural relaxation occurs spontaneously in vitreous materials, as they are thermodynamically out of equilibrium. This phenomenon can be accelerated by thermal treatments near the glass transition region, leading to gradual changes in properties over time. A recent study by our research group (not published yet) showed that, in glasses containing a single network modifier, the structura…
This master's project aims to develop and characterize new oxide glasses with optimized optical properties by integrating our current understanding of glass structure, physicochemical characterization, and machine learning (ML) algorithms. Focus will be placed on the rational design of silicate-based glasses with low silica content, particularly lead-free systems incorporating ZnO, TiO2, …

The fluoride containing bioactive glass F3 with nominal composition 44.8 SiO2 - 2.5 P2O3 - 36.5 CaO - 6.6 Na2O - 6.6 K2O - 3.0 CaF2 mol% is a highly promising candidate as bone replacement material. However, its strong surface crystallization tendency, which retard or block viscous flow sintering, demands a thorough understanding on the crystal nucleation and growth mechanisms to prevent …
The addition of niobium as a mixed glass former can lead to unique properties and significant advances in materials science, and is of great relevance for understanding and predicting the behavior of glassy materials. This scientific initiation project aims to characterize and analyze the properties of lithium phosphate glasses that incorporate niobium in their composition, in order to in…
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…

This proposal, submitted under the program Bolsa de Estágio de Pesquisa no Exterior (BEPE) for postdoctoral researchers funded by FAPESP, seeks support for a twelve-month international research stay by the postdoctoral researcher Dr. Carsten Blaess (UFSCar) at Otto Schott Institute for Materials Research (OSIM) at the Friedrich Schiller University in Jena. The project aims to investigate …
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…
This project aims to evaluate the Jiusti-Zanotto-Cassar-Andreeta (JZCA) model for glass-forming ability (GFA) and to test the hypothesis that glasses with low viscosity at the liquidus temperature may still exhibit good GFA if their liquidus temperature is also low. We have combined the SciGlass® and Interglad® databases to identify glasses with both low liquidus temperature and low visco…
Glasses are thermodynamically unstable materials. Hence, they spontaneously relax towards the supercooled liquid state. The structural relaxation process is an irreversible, time-dependent phenomenon, which may be experimentally detected by measuring some property over time at temperatures close to the laboratory glass transition. Even though the kinetics of the structural relaxation proc…
The large increase in interest in aesthetic and functional oral aspects has led many people to switch from metal or metal alloys coated with porcelain to fixed ceramic prostheses. As a consequence, there has been a substantial increase in worldwide research involving dental materials in the past few years. In this scenario, a promising candidate for those applications is glass-ceramic pro…
