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.
KAUST researchers are investigating the sources and chemistry of airborne particles to tackle urban air pollution. The research integrates laboratory simulations of atmospheric reactions with field measurements to understand the formation mechanisms of particulate matter (PM). They are also developing cellular and animal models to test how different air pollutants affect human health, in collaboration with the Center of Excellence for Smart Health. Why it matters: This research can inform targeted control strategies to manage emissions and improve air quality in Saudi Arabia and other countries facing similar pollution challenges.
The AQABA project, a collaboration involving KAUST and international institutions, studies air quality and climate change in the Arabian Basin using a marine research vessel. The vessel traveled from France through the Suez Canal, around the Arabian Peninsula, and stopped at KAUST. Researchers presented findings on atmospheric dust, air pollution, and aerosol measurements, highlighting the impact of dust on renewable energy and air pollution on health. Why it matters: The project provides crucial data for understanding and addressing climate challenges and air quality issues in the Middle East.
KAUST researchers found that wildfire smoke particles act as chemical factories under sunlight, producing harmful oxidants like peroxides. These particles bypass traditional suppression by nitrogen oxides in polluted environments, generating oxidants internally. The study reveals that colored organic molecules in biomass-burning aerosols act as photosensitizers, triggering rapid reactions. Why it matters: The findings highlight that current air-quality and climate models underestimate oxidant production from wildfires, with implications for anticipating health risks and environmental impacts in regions like Saudi Arabia.
KAUST is hosting Junfeng (Jim) Zhang from Duke University to study air pollution's impact on health in Saudi Arabia. Zhang will collaborate with KAUST faculty to assess the health effects of environmental stressors using epidemiology and toxicology. Air pollution causes significant premature deaths and loss of life expectancy in Saudi Arabia. Why it matters: This research will inform evidence-based policies and treatment strategies to combat respiratory illnesses linked to air pollution in Saudi Arabia and the broader region.
Researchers from King Abdullah University of Science and Technology (KAUST) conducted a study revealing that Red Sea corals absorb and accumulate various compounds, including pharmaceuticals, personal care products, and herbicides, thereby recording a long-term chemical footprint of human activity. The study detected substances like antibiotics, anti-inflammatories, and the herbicide atrazine across 15 reefs in three Red Sea regions, noting that some chemicals were found in higher concentrations offshore due to ocean currents. This research demonstrates how corals can provide a more comprehensive, time-integrated picture of environmental exposure than water samples alone. Why it matters: This work offers a valuable tool for environmental monitoring and informing policy in Saudi Arabia as it expands coastal tourism and other sectors, particularly for the unique Red Sea coral reef ecosystems.
KAUST and Saudi Aramco collaborated to develop a laser-based sensor for detecting trace amounts of gas leaks in petrochemical plants. The sensor uses machine learning to identify specific gases, differentiating it from previous sensors that only detect large leaks. The technology can differentiate between closely related industrial gases like benzene, toluene, ethyl benzene and xylene (BTEX). Why it matters: This innovation enables proactive monitoring and rapid pinpointing of leaks, enhancing safety, environmental protection, and operational efficiency in the petrochemical industry.
KAUST startup uODS signed an MoU with Saudi Aramco Base Oil Company (Luberef) to develop and deploy technology removing sulfur from hydrocarbons. The uODS process, based on KAUST's sonochemistry research, reduces sulfur in marine fuels to meet IMO 2020 regulations. Luberef aims to reduce its environmental footprint by piloting the uODS technology at its Jeddah refineries, with uODS set to produce 10 tons per day of desulfurized fuel for testing. Why it matters: The partnership demonstrates KAUST's role in addressing Saudi Arabia's environmental goals and showcases the potential of university spin-offs to contribute to a more sustainable oil industry in the region.
