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.

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's Functional Nanomaterials Laboratory (FuNL), led by Prof. Osman Bakr, focuses on synthesizing nanomaterials with novel optical, electronic, and magnetic properties for solar cells and other devices. The lab's research centers on controlling the size and composition of nanoparticles to optimize light absorption across different wavelengths. Unlike silicon-based solar cells, nanoparticle-based solar cells can be processed at low temperatures and potentially integrated with roll-to-roll printing. Why it matters: This research could lead to more efficient and versatile solar energy solutions, including printable photovoltaic thin films for buildings and flexible electronics.
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.
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.
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.
