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 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.
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 alumnus Zhenwei Wang (Ph.D. '18), who studied under Professor Husam Alshareef, focused on developing oxide semiconductors for transparent electronics during his time at KAUST. Currently a postdoctoral researcher at the Okinawa Institute of Science and Technology (OIST), he is now developing novel biological sensing devices using nanoparticles. Wang credits KAUST's facilities and support for enabling him to overcome research challenges. Why it matters: The story highlights KAUST's role in fostering materials science talent and contributing to advancements in bio-sensing technology, with implications for future medical diagnostics.
Three KAUST Ph.D. students, Dalal Alezi, Samah Mohamed, and Yevhen Fatieiev, have been selected to attend the 67th Lindau Nobel Laureate Meeting in Lindau, Germany. The meeting will bring together young scientists and Nobel laureates in chemistry for a week of activities. Alezi's research focuses on metal-organic materials, Mohamed develops chemical kinetic models for combustion, and Fatieiev works on magnetic nanoparticles. Why it matters: This highlights KAUST's commitment to fostering scientific talent and providing opportunities for its students to engage with leading researchers in their fields, enhancing the university's global reputation.
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.
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.
