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.
KAUST researchers, in collaboration with Nanyang Technological University, have discovered a unique chiral structure in gold nanowires. The nanowires exhibit a Boerdijk-Coxeter-Bernal (BCB) helix structure, achieved through a seed-mediated substrate growth method, reaching a minimum diameter of 3 nanometers. High-resolution transmission electron microscopy (HRTEM) at KAUST was crucial in revealing the structure. Why it matters: This breakthrough in chiral metallic nanowire production could lead to advancements in chemical separation, sensing, and catalysis due to the unique properties of chiral crystals.
KAUST researchers led by Andrea Fratalocchi are developing a nanomaterial, initially recognized as the "blackest black" by Guinness World Records, to enhance solar cell efficiency. The material, made from gold nanoparticles, absorbs over 99% of visible light and 98% of infrared. The team is working to create the material from less costly alternatives to gold for energy production applications. Why it matters: This research could lead to significant advancements in solar energy harvesting, addressing a critical need for efficient light absorption in renewable energy technologies within the region and globally.
KAUST startup Quantum Solutions manufactures quantum dots, semiconducting nanoparticles that emit light with controllable energy. These dots are being explored for applications including displays, photodetectors, and solar cells. Quantum dots can enhance the efficiency of silicon solar panels by absorbing infrared light. Why it matters: This highlights the potential of KAUST-incubated startups to contribute to advanced materials science and renewable energy technologies in the region.
KAUST Ph.D. student Amal Mohammed Alamri was a finalist in the July 2018 IEEE nanoArt Competition, part of the 18th IEEE International Conference on Nanotechnology in Cork, Ireland. Her work, displayed at University College Cork and Crawford/CIT Gallery, involved stacking n-type MoS2 single crystal with p-type perovskite CH3NH3PbBr3 single crystal. Alamri's IEEE Nano paper entitled "Photonic Single Crystal Heterostructures based on Perovskites/Molybdenum disulfide" was also presented at the conference. Why it matters: This highlights KAUST's contribution to nanotechnology research and its students' participation in international scientific events.
KAUST researchers are developing a streamlined COVID-19 diagnostic testing method using superparamagnetic nanoparticles (MNPs). The team, led by Assistant Professor Mo Li, aims to address reagent shortages and improve automation by creating an in-house extraction kit compatible with inactivated samples. Associate Professor Samir Hamdan identified a protocol for making silica-coated MNPs that survive inactivation reagents, enabling magnetic separation without centrifugation. Why it matters: This innovation could significantly increase testing capacity in Saudi Arabia and globally by reducing biosafety risks, reagent dependence, and manual processing.
Researchers at KAUST have developed a nanocomposite material that converts X-rays into light with nearly 100% efficiency.
