Researchers at KAUST, USTC, and SUSTech have developed a method for carbon capture and storage using guanidinium sulfate salt to create clathrate structures that trap CO2 molecules. This salt-based structure mimics methane hydrate activity and captures CO2 through physisorption, without water or nitrogen interference. The method allows CO2 to be carried as a solid powder at ambient temperature and pressure, offering a less energy-intensive alternative to traditional methods. Why it matters: This innovation introduces a new, energy-efficient way to store and transport CO2 as a solid, potentially revolutionizing carbon capture and storage technologies in the region and beyond.
KAUST researchers in the Functional Materials Design, Discovery & Development group have discovered a minimal edge transitive net with high connectivity. This net was used as a blueprint for the design and construction of metal-organic frameworks (MOFs). Specifically, a new rare earth nonanuclear carboxylate-based cluster was used as an 18-connected MBB to form gea-MOF-1. Why it matters: This work contributes to the advancement of solid-state materials design, which could have broad implications for energy and environmental sustainability in the region.
KAUST Professor Mohamed Eddaoudi is researching MOFs (metal-organic frameworks). MOFs have applications for clean energy. Why it matters: This research contributes to KAUST's and Saudi Arabia's broader clean energy and sustainability initiatives.
KAUST researchers have made several advances, including a new computational model of the Red Sea's ocean circulation. They also synthesized new metal-organic frameworks for gas storage with applications in green and medical tech. Additionally, they presented a mathematical solution for microgrid cybersecurity. Why it matters: These diverse research projects highlight KAUST's contributions to environmental modeling, materials science, and critical infrastructure protection in the region.
KAUST researchers, led by Mohamed Eddaoudi, developed a metal-organic framework (MOF) capable of selectively adsorbing water, challenging the conventional view of MOF instability in water. They also advanced MOF understanding by adapting high-resolution transmission electron microscopy to observe their atomic structure. KAUST hosted the Innovation to Impact Roundtable, fostering collaboration between academics and industry leaders from the U.S. and Saudi Arabia. Why it matters: These activities highlight KAUST's role in materials science innovation and fostering international research collaborations to advance technological development in Saudi Arabia.
KAUST Professor Niveen Khashab has received the 2023 Cram Lehn Pedersen Prize in Supramolecular Chemistry, a prestigious international award. The prize recognizes her original work in supramolecular chemistry and self-assembly of organic molecules, particularly in designing smart nanomaterials. Khashab will receive the award, along with a £2,000 honorarium, at the 2023 International Symposium on Macrocyclic and Supramolecular Chemistry in Iceland. Why it matters: This award highlights the growing prominence of materials science research in the GCC region and KAUST's contributions to the field of supramolecular chemistry.
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.
KAUST and Partanna have launched a 12-month R&D partnership to enhance CO2 removal in concrete manufacturing. The collaboration will integrate Partanna’s formula with KAUST’s Direct Air Capture (DAC) technology. Partanna's patented concrete avoids Portland Cement and uses a binder made from natural and recycled materials, enabling CO2 absorption. Why it matters: This partnership highlights Saudi Arabia's commitment to sustainable construction and carbon-negative technologies, potentially revolutionizing building practices in the region and beyond.
