A KAUST and King Abdulaziz University research team is using superhydrophobic sand to grow crops like tomatoes with less water. Superhydrophobic sand reduces water consumption in agriculture, the world's largest consumer of freshwater. The sand was developed by KAUST's Himanshu Mishra and Ph.D. student Adair Gallo Junior. Why it matters: This research offers a promising solution for water conservation in agriculture, especially in arid regions like the Arabian Peninsula, addressing critical water security challenges.
ClimateCrete, a KAUST spinout, has raised investment for its technology that modifies sand particles to make them suitable for concrete manufacturing. The patented tech reduces the need for cement and lowers CO2 emissions by up to 60 percent. Tests show a significant increase in strength compared to untreated sand. Why it matters: This technology addresses the global shortage of suitable construction sand and supports Saudi Arabia's carbon-neutrality goals by enabling a 100% domestic supply chain for concrete.
A collaborative research team including KAUST scientists has located a major sink for missing ocean plastic in coastal sediments and mangrove forests of the Red Sea and Arabian Gulf. Core samples showed a pattern of plastic sedimentation aligning with the history of global plastic production since the 1950s. Mangroves efficiently lock up microplastics in coastal soil, with plastic burial rates increasing similarly to global production. Why it matters: The findings highlight the critical role of mangroves in trapping plastic pollution and provide evidence that plastic sedimentation marks the start of a new geological epoch, the Anthropocene.
KAUST faculty member Marco Canini is researching networked systems, focusing on improving their design, implementation, and operation. His work centers on Software-Defined Advanced Networked and Distributed Systems (SANDS). Canini aims to address challenges related to reliability, performance, security, and energy efficiency in large-scale networked computer systems. Why it matters: This research contributes to the development of more dependable and efficient digital infrastructure in Saudi Arabia, aligning with KAUST's mission to advance science and technology.
KAUST participated in the International Exhibition & Conference on Higher Education in Riyadh, showcasing interdisciplinary research and startups. KAUST researchers presented smart solar windows that convert sunlight into electricity using organic photovoltaic materials. Another KAUST team developed SandX, a sand and paraffin wax composite, which significantly reduced water evaporation and increased crop yields in field trials. Why it matters: These innovations demonstrate KAUST's commitment to advancing sustainable energy and desert agriculture in Saudi Arabia through cutting-edge research and technology commercialization.
KAUST researchers have found that dust clouds in the Arabian Peninsula are three times larger than previously estimated by current models. The study, published in the Journal of Geophysical Research: Atmospheres, uses refined mathematical models and data collected since 2012 to analyze the impact of coarse dust particles. The updated model indicates that larger particles contribute to over 80% of dust mass on land, leading to significant efficiency loss for solar technology, estimated at 15-45% depending on location. Why it matters: Accurate dust modeling is crucial for the strategic deployment and maintenance of solar technology, supporting Saudi Arabia's sustainable economy goals.
KAUST researchers discovered that dust from the Middle East has a cooling effect over land and the Red Sea. Satellite data indicates dust concentration over the Red Sea is greater than over land, causing significant radiative cooling. The study, published in the Journal of Geographical Research, highlights the climatological dust radiative forcing over the southern Red Sea as the largest globally. Why it matters: Understanding the impact of regional dust on climate change and the Red Sea's ecosystem is crucial for environmental strategies in the Middle East.
J. Carlos Santamarina, a Professor of Earth Science and Engineering at KAUST, is researching geomaterial behavior and subsurface processes. His work focuses on energy geo-engineering, resource recovery, and geological storage of energy waste. He uses particle-level experiments, numerical methods, and monitoring systems to understand coupled thermo-hydro-bio-chemo-mechanically processes. Why it matters: This research contributes to energy sustainability and addresses global energy challenges through advanced geotechnology.
