Porous Carbon Fiber Functionalization and Thermochemical Degradation of Polystyrene-based Plastics for Resource Recovery
… for the extraction of REEs. Second, the thermochemical degradation of PS and PS-based engineering plastic into benzene and alkylbenzene were explored. In the first project, a greener REE leaching method followed by solid-phase extraction using functionalized PCF was developed. To dissolve …

Investigation on Physics-based Multi-scale Modeling of Contact, Friction, and Wear in Viscoelastic Materials with Application in Rubber Compounds
… friction coefficient when there is no trace of thermochemical degradation on the rubber surface. Investigating the wear mechanism of rubber samples on three different surfaces reveals that the contribution of fatigue wear rate is less important than other wear mechanisms such as abrasive wear …

Integrating Structural Fire Analysis with Hybrid Fire Testing: A Framework for Enhanced Stability, Software development and Full-Scale Evaluation.
… and nonlinear strain escalation associated with thermochemical degradation and is calibrated against experimental data. Implemented in OpenSees for Fire [1], it significantly improves simulation accuracy during heating and cooling phases. Finally, the thesis introduces OpenSFire, a graphical …

Upcycling of Polystyrene, Polyolefin, and Polyvinyl Chloride Waste into Chemicals, Surfactants, and Lubricants
… which relies on a two-step process, begins with thermochemical degradation carried out with AlCl3 generating quantitative yields of benzene by dephenylation. Subsequently, structurally distinct alkyl chlorides, sulfinyl chlorides, and acyl chlorides are introduced in the reaction to afford …

USE OF BIOCHAR, OBTAINED FROM THE VALORISATION OF AGRO-RESIDUAL BIOMASS, AS FUNCTIONAL FEED FOR MONOGASTRIC ANIMALS
… alongside bio-oil and syngas through the thermochemical degradation of biomass at high temperatures (over 350°C) in an oxygen-limited environment. It has garnered significant interest for its potential to mitigate climate change through carbon sequestration and the reduction of greenhouse …

In-Situ Investigations of Calcium-Magnesium-Aluminosilicates (CMAS) Infiltration Effects on Thermal Barrier Coatings Under Extreme Environments Replicating Jet Engines
… risking crack formation. While molten, the CMAS thermochemically alters and destabilizes the coating, also risking coating failure. Premature, localized spallation failure of these ceramic thermal barrier coatings (TBCs) exposes underlying metallic components to the extreme temperatures of the …
