KAUST marine biologist Maggie Johnson is studying how to accurately measure environmental conditions to optimize coral restoration, focusing on temperature and light. She highlights the variability in precision and accuracy of commercially available instruments for measuring these parameters. Johnson notes that some instruments fail in the Red Sea's warm temperatures and high salinity, providing incorrect data. Why it matters: Accurate environmental monitoring is crucial for the success of coral reef restoration efforts in the face of climate change, especially in extreme environments like the Red Sea.
KAUST researchers developed a laser-based sensor that exploits the "chirp" phenomenon in semiconductor lasers to accurately measure gas temperature in combustion systems. The sensor uses spectroscopic measurements at very fast rates (1.0 MHz) and can measure temperature at the nanosecond timescale at repetition rates of thousands of kHz. The new sensor reduces uncertainty compared to previous methods and works rapidly in transient shock tube experiments. Why it matters: This in-house development provides a non-invasive, accurate, and easily implementable system for combustion research, with implications for understanding and improving energy efficiency.
KAUST researchers created a flexible temperature array by drawing a resistor structure with a silver conductive ink pen on Post-it paper. The array functions as an artificial skin sensor. The device demonstrates a low-cost approach to wearable sensors. Why it matters: This research offers a path to scalable and accessible sensor technology for health monitoring and other applications in the region.
KAUST Associate Professor Jürgen Kosel has been named a distinguished lecturer of the Institute of Electrical and Electronics Engineers (IEEE) Sensors Council for 2020-2022. Kosel's research focuses on sensors and transducers with applications in animal monitoring, precision farming, Formula One racing, and biomedical instruments. His group is also developing magnetic devices for high-density data storage and cancer treatment. Why it matters: This recognition highlights KAUST's contributions to sensor technology and its potential impact on diverse fields, including healthcare in developing regions.
KAUST Research Scientist Dr. Ram Karan received a Young Scientist Award at the 15th International Congress on Thermophiles in Japan for his work on extremozymes from Red Sea brine pools. His research focuses on identifying, purifying, and bioengineering microbial proteins from these pools. He utilizes single-amplified genomes (SAGs) to produce extremozyme proteins without needing to grow cells in the lab. Why it matters: This award recognizes KAUST's innovative research into extremophiles, which have the potential to develop novel, sustainable biotechnical processes for industrial applications.
KAUST researchers have developed a passive cooling system that uses solar energy to evaporate water and regenerate salt for reuse, achieving temperatures as low as 3.6 degrees Celsius. The system uses ammonium nitrate (NH4NO3) due to its high solubility and low cost. The crystallized salt stores solar energy and can be reused for cooling when needed. Why it matters: This off-grid design offers a sustainable and inexpensive cooling solution for communities in hot regions with limited electricity access, addressing a critical need exacerbated by climate change.
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.
Dr. Giampiero Marchegiani from the Quantum Research Center (QRC) co-authored a paper in Nature Nanotechnology on bipolar thermoelectricity in Josephson junctions. The research demonstrates the generation of electrical current using heat, observing bipolar thermoelectricity where the device generates either positive or negative electrical signals without extra control. Integrating these junctions into a bipolar thermoelectric Josephson engine (BTJE) allowed the generation of up to ~140nW/mm2 of electric power at subkelvin temperatures. Why it matters: This BTJE engine may have applications in superconducting technology, potentially strengthening the UAE's position in quantum technologies.
