KAUST researchers have developed a method using high-intensity pulses of light to remove carbon-based organic micropollutants from wastewater. By using a pulsed light system previously used for semiconductor materials, the team dramatically accelerated the photodegradation treatment. The high-intensity pulsed light (HIPL) triggers decomposition of organic micropollutants (OMPs) with extraordinary degradation rates within milliseconds. Why it matters: This treatment offers a potentially scalable solution to the increasing environmental problem of OMPs in waterways, addressing a critical need in water treatment technologies for the region.
The Technology Innovation Institute (TII) in Abu Dhabi has launched a 2-micrometer high-power fiber laser for medical and industrial applications. Developed by TII's Directed Energy Research Center, the Thulium-based laser is efficient, compact, and scalable, enabling precise interaction with water-rich materials. TII has partnered with LIMA Photonics, a German MedTech startup, to integrate the laser into clinical solutions, including urinary stone treatment and prostate surgery. Why it matters: This laser technology and partnership showcase the UAE's commitment to translating advanced research into healthcare solutions, positioning Abu Dhabi as a hub for medical technology innovation.
The Directed Energy Research Center (DERC) is partnering with Montena Technology to study high-altitude electromagnetic pulses and design infrastructure safeguards. DERC is also collaborating with Radaz to evaluate ground penetrating and synthetic aperture radars in Abu Dhabi, aiming to identify natural resources. Additionally, DERC and Université de Picardie Jules Verne are working on laser sources and sensors, with a DERC researcher spending four years in France. Why it matters: These partnerships enhance DERC's research capabilities in critical areas like infrastructure protection, resource exploration, and advanced sensing technologies.

A KAUST-led team developed a nano-optical chip capable of generating and controlling nanoscale rogue waves. The chip, detailed in Nature Physics, uses a planar photonic crystal fabricated at the University of St. Andrews and tested at FOM Institute AMOLF. It enables unprecedented control over these rare, high-energy events, opening possibilities for energy research and environmental safety. Why it matters: This innovation provides a new platform for studying extreme events and potentially harnessing their energy, advancing both fundamental science and practical applications in areas like renewable energy and disaster prevention.
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 Professor Boon Ooi, Nobel laureate Shuji Nakamura, and colleagues are collaborating on laser-based solid state lighting (SSL) and visible light communications (VLC). The team is using gallium nitride (GaN) to develop high-performance semiconductor laser devices, leveraging nanofabrication techniques at KAUST. They demonstrated that their laser-based VLC system is over 20 times faster than LED-based Li-Fi systems. Why it matters: This research could enable faster, more energy-efficient data transmission using visible light, with potential applications in both terrestrial and underwater communication.
A conference at KAUST covered topics related to hydrophobic interfaces. The event brought together researchers and experts in the field. King Abdullah University of Science and Technology hosted the conference. Why it matters: Events like this foster collaboration and knowledge sharing in materials science and engineering.
