Sol-gel-derived transparent glass-ceramics for photonics

Photonic glass-ceramics are two-phase materials constituted by nanometer sized crystals, passive or activated by luminescent species, embedded in a glass matrix. Among the different techniques used to fabricate transparent glass ceramics the sol-gel route is highly appreciated because it allows to explore different compositions and develop novel functionalities. By engineering glass-ceramics chemistry, nature, or volume fractions of crystalline and amorphous phases, several interesting proper...

Electronic Nose-Based Assessment of Cardiovascular Disease Severity Using Blood Analysis

An electronic nose-based approach for cardiovascular disease severity assessment is presented, leveraging blood samples instead of conventional breath analysis to improve standardization within clinical workflows. The proposed method extends current e-nose applications by enabling 3-class discrimination among control subjects and two levels of disease severity, allowing finer clinical stratification. Sensor responses are enhanced through the integration of optimized custom sensors and analyze...

SiO2-TiO2 hybrid coatings applied on polymeric materials for flexible photonics applications

For the development of flexible photonic devices, polymeric substrates are of capital importance due to their low cost and mechanical flexibility. However, they are sensitive to the environment’s influence on their durability. To overcome problems of polymeric substrates’ stability, we developed organically modified hybrid silica-titania coated PET (polyethylene terephthalate) films. The focus was put on the determination of the optical properties’ changes in dependence on the synthesis and m...
