The 34th General Assembly and Scientific Symposium (GASS) of the International Union of Radio Science (URSI) will be held in Rome from August 28 to September 4. The Technology Innovation Institute’s Directed Energy Research Center (DERC), led by Dr Chaouki Kasmi, will present a tutorial and five scientific papers. DERC's presentations will focus on advances in electromagnetics and optoelectronics. Why it matters: DERC's participation highlights the UAE's growing role in international radio science research and development.
John Pantoja from the Directed Energy Research Center at TII presented a method to estimate the effects of high current impulses on electro-conductive textiles. The method uses specific action, a parameter to determine burst of exploding wires, and a new equivalent electrical circuit. The model estimates the current intensity needed to melt the conductive layer at contact areas between yarns, and is validated experimentally on ripstop woven fabrics. Why it matters: The research explores conductive fabrics for portable lightning protection shelters, potentially reducing lightning-related accidents in high-risk populations.
Dr. Fernando Albarracin from the Technology Innovation Institute has presented a novel microwave applicator design for hyperthermia, potentially useful in cancer treatment. The design combines two flat dielectric graded-index (GRIN) lenses to localize electromagnetic energy within a specific spot in the tissue. This system offers a suitable alternative to conventional antenna-based applicators by considering the interface between free space and human tissue. Why it matters: This research introduces a new approach to hyperthermia treatment that could improve the precision and effectiveness of cancer therapy in the region.
KAUST is collaborating with Coastline Company to convert Red Sea seaweed, specifically Sargassum, into valuable commodities. This initiative addresses the environmental hazard of decomposing seaweed blooms and promotes local employment and a circular economy. KAUST is exploring the use of Sargassum to produce fabric raw materials, alginate for food, biostimulants for agriculture, and fucoidans for therapeutic applications, processing it in a biorefinery manner. Why it matters: This project aligns with Saudi Arabia's sustainability priorities and demonstrates the potential of marine biomass in various industries, including fashion through collaboration with the Saudi Fashion Commission and PYRATEX®.
