SCIENTIFIC PROJECT

"Laser-induced dYnamics at nanO iNterfaces: from fundamentals to PhotothermAl control (LYON-PA)"
 
The LYON-PA project investigates heat transport at solid–liquid nanoscale interfaces, focusing on Thermal Boundary Resistance (TBR), which limits heat dissipation in nanoelectronics and photothermal therapy (PTT). The aim is to understand and control TBR between carbon-based nanomaterials (e.g., carbon nanotubes, graphene) and biologically relevant liquids to enhance heat transfer efficiency, particularly for cancer and antibacterial PTT applications.
The research combines ultrafast pump–probe spectroscopy to measure nanoparticle cooling dynamics, continuum thermo-optical and thermo-acoustic modeling to predict interfacial heat exchange, and time-resolved second harmonic generation to probe interface-specific processes. Conducted at Institut Lumière Matière (Lyon), the project integrates experimental and theoretical approaches to quantitatively determine and optimize TBR, enabling improved thermal regulation and more effective, selective photothermal treatments

BIOGRAPHY

Andrea Tognazzi is a researcher in Electromagnetic Fields at the University of Palermo. He obtained his Master’s degree in Physics from the Università Cattolica del Sacro Cuore in Brescia and his Ph.D. in Information Engineering from the University of Brescia. Prior to joining the University of Palermo, he held postdoctoral positions at the University of Brescia and the University of Padova, where he worked on thermo-optical dynamics in nanomaterials. His research focuses on nanostructures and metasurfaces for photonic applications, with particular emphasis on nonlinear frequency generation and the dynamic modulation of optical responses.
