This research develops cavity-based methods for controlling thermal radiation by transforming random heat emission into coherent, directional thermal beams. Unlike traditional narrowband approaches, the technique enables broadband heat control using practical materials such as silicon and germanium, with potential applications in energy efficiency, waste-heat recycling, cooling technologies, and climate mitigation.

This research improves electric resistance welding by modelling heat transfer and weld formation physics. By identifying and controlling the weld point location, it replaces trial-and-error with predictive engineering rules. The work enables stronger, safer pipelines, supporting the adoption of advanced materials needed for reliable infrastructure in a clean energy future.

This research addresses overheating in 5G base stations, where vertically mounted electronics create dangerous hotspots. By using passive vapor chamber cooling, heat is efficiently redistributed without added energy use. Experimental and modeling work shows vapor chambers improve reliability and sustainability, supporting faster, more stable 5G and future network infrastructure.
