KAUST researchers presented their work on stabilizing nanoparticle catalysts at the 252nd American Chemical Society Meeting & Exposition. The team devised a "molecular Scotch tape" using a silica gel support coated with a single molecule layer of soft material containing sulfur. This approach allows nanoparticles to stick to one side while leaving the other side free for catalysis, preventing aggregation without killing the catalyst. Why it matters: This innovation in catalyst stabilization could lead to more efficient and sustainable chemical processes, impacting various industries.
Researchers at KAUST have synthesized a novel porous organic polymer (POP) with enhanced CO2 adsorption properties. The POP material has aldehydes that allow for post-synthetic functionalization by amines, improving interactions between CO2 and the material. Experiments showed a significant enhancement of CO2 affinity and a drastic increase in heats of adsorption. Why it matters: This research provides a promising new material for economic and efficient carbon capture, addressing the urgent need to reduce CO2 emissions.
Three researchers from the UAE's Advanced Materials Research Center (AMRC) are pursuing advanced degrees at the University of Manchester through the Advanced Technology Research Council’s NexTech program. Shamma Alhashmi is pursuing a PhD in chemical engineering, while Mohamed Alnuaimi and Omar BaNabila are working towards master's degrees in Advanced Engineering Materials. Their research focuses on nanomaterials, piezoelectrics, and material damage analysis, respectively. Why it matters: This initiative demonstrates the UAE's investment in STEM education and aims to enhance domestic research capabilities in advanced materials by providing international training opportunities for promising Emirati researchers.
KAUST Ph.D. student Amira Alazmi won the Nanoscale poster prize at the Royal Society of Chemistry Symposium 2018 in London for her work on cobalt ferrite/reduced graphene oxide composites as a T2 contrast agent for magnetic resonance imaging. Her research focuses on understanding the synthesis of graphite oxide and reduced graphene oxide. Alazmi's work demonstrates the importance of selecting graphene oxide synthesis methods based on the intended application. Why it matters: This award recognizes the high-impact research being conducted at KAUST and highlights the importance of materials science in advancing medical imaging technologies.
Researchers at KAUST, Fraunhofer ISE, and University of Freiburg developed a method using 1,3-diaminopropane dihydroiodide (PDAI) to treat the perovskite surface of perovskite silicon tandem solar cells. The treated solar cells achieved a conversion efficiency of 33.1% and an open-circuit voltage of 2.01 volts. The devices maintained performance at over 40°C for over 1500 hours along the Saudi coast. Why it matters: This innovation overcomes challenges in surface passivation of textured perovskite cells, paving the way for more efficient and stable solar energy solutions suitable for deployment in hot climates.
Dr. Nesma Aboulkhair, Additive Manufacturing Lead Researcher at TII, has been ranked among Stanford's top 2% of scientists for single-year citations for the second consecutive year. Dr. Aboulkhair joined TII in April 2021 and also holds a visiting academic position at the University of Nottingham in the UK. Her research focuses on metal additive manufacturing processes, including powder-based and droplet-on-demand methods, and she has secured over GBP2 million in funding. Why it matters: This recognition highlights the growing expertise in advanced manufacturing within UAE research institutions and TII's ability to attract and foster high-impact researchers in critical fields.
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 have developed polytriazole membranes for energy-efficient crude oil fractionation, as detailed in a recent Science Magazine paper. Led by Dr. Suzana Nunes and Dr. Stefan Chisca, the team created membranes that can withstand harsh industrial conditions like high temperatures and organic solvents. The membranes offer a low-carbon footprint alternative to traditional separation techniques like distillation. Why it matters: This innovation could significantly reduce energy consumption and promote a circular carbon economy in the petrochemical industry within the GCC region and beyond.
