Five Emirati researchers from the Directed Energy Research Center (DERC) concluded a 5-week training course in Switzerland on laser processing and laser-matter interaction at Empa-Swiss Federal Laboratories. The training involved hands-on experience with high-end equipment to conduct independent research. The DERC researchers will contribute to DERC’s projects and help operate its AI-powered laser-matter interaction laboratory. Why it matters: This international training enhances local expertise in advanced laser technology, crucial for developing AI-driven material science capabilities in the UAE.
KAUST researchers found Y-series nonfullerene acceptors enhance the outdoor stability of organic solar cells, enabling energy-efficient windows. They also used satellite data to show managed vegetation can mitigate rising temperatures across Saudi Arabia's agricultural regions. Additionally, they developed DeepKriging, a deep neural network, to solve complex spatiotemporal datasets and tested it on air pollution. Why it matters: This research addresses critical challenges in renewable energy, climate change, and AI data privacy relevant to Saudi Arabia and the broader region.
DERC is partnering with EPFL in Switzerland on a four-year project using EMTR and ML to study electromagnetic disturbance localization in PCBs. Professor Farhad Rachidi (EPFL) and Dr. Nicolas Mora (DERC) will mentor a PhD student. The collaboration builds on prior relationships between DERC researchers and Prof. Rachidi's lab. Why it matters: The partnership strengthens DERC's methodological expertise and international recognition in electromagnetic studies, potentially leading to further collaborations.
KAUST researchers have achieved a breakthrough by passing the damp-heat test for perovskite solar cells (PSCs), a rigorous assessment of their ability to withstand prolonged exposure to high humidity and temperatures. The team engineered 2D-perovskite passivation layers that block moisture and enhance power conversion efficiencies. The successful test, which requires maintaining 95% of initial performance after 1,000 hours at 85% humidity and 85 degrees Celsius, marks a significant step toward commercialization. Why it matters: This advancement addresses a critical weakness of PSCs and brings the technology closer to competing with silicon solar cells in terms of stability and longevity, crucial for widespread adoption of renewable energy.
KAUST scientists developed a new perovskite solar cell design using thin perovskite layers at the top and bottom of the interface. The new design achieves a power conversion efficiency of 25.6%, comparable to silicon solar cells, with only a 5% efficiency loss after 1000 hours of high heat exposure. The key innovation is the use of a specific ligand that interacts effectively with the 3D perovskites for passivation, maintaining purity in the thin layers. Why it matters: This advancement enhances the stability and efficiency of perovskite solar cells, making them a more viable and cost-effective alternative to silicon, especially for countries like Saudi Arabia aiming to increase renewable energy reliance.
The Directed Energy Research Center (DERC) at TII will participate in the 2021 Joint IEEE International Symposium on Electromagnetic Compatibility, Signal & Power Integrity, and EMC Europe. DERC will present scientific papers and a tutorial on Nuclear Electromagnetic Pulse (NEMP) with ETS Lindgren, led by Dr. Nicolas Mora. Dr. Mora and Professor Farhad Rachidi will present a tutorial on High Altitude Electromagnetic Pulse (HEMP), Electromagnetic Pulse (EMP), and Intentional Electromagnetic Interference (IEMI). Why it matters: The participation highlights the UAE's growing expertise in electromagnetic compatibility and protection, particularly regarding critical infrastructure resilience against electromagnetic threats.
KAUST faculty member Enrico Traversa is researching nanostructured materials for sustainable development in energy, environment, healthcare, and solid oxide fuel cells (SOFCs). His work focuses on developing next-generation SOFCs based on chemically stable proton-conducting electrolytes to reduce operating temperatures. Traversa also develops scaffold biomaterials for tissue regeneration, aiming to create heart tissue using patient-derived stem cells. Why it matters: This research contributes to KAUST's focus on energy, water, environment and food, with potential for advancements in clean energy and regenerative medicine.
KAUST researchers led by Dr. Gyorgy Szekely are developing selective porous membranes to replace energy-intensive separation techniques like distillation in the chemical manufacturing industry. These membrane processes could reduce energy consumption by up to 90% compared to traditional methods. Szekely's team uses AI to optimize separation materials by identifying patterns in previously fragmented data. Why it matters: This research has the potential to significantly reduce the environmental impact of chemical manufacturing, a sector known for its high energy consumption.
