KAUST researchers developed a crystallization process for organic molecules with potential applications in electronics, pharmaceuticals, and food. They produced "strained organic semiconductors," which can lead to high-performance, low-cost, flexible, and transparent electronic devices. The team combined X-ray beams with high-speed cameras to record the crystallization process, revealing that quick evaporation and nanoscale thinness play a role in producing ideal crystal lattices. Why it matters: This new method offers unprecedented control over crystal formation, potentially revolutionizing the production of plastic electronics and impacting other industries relying on specific crystal structures.
The University of Sydney and KAUST jointly hosted a symposium on April 10 focused on enhancing research collaborations in materials, energy, and water. The symposium featured presentations from faculty at both universities, including Prof. Karl Leo and Prof. Archie Johnston. A poster session highlighted the work of over 30 students and researchers, with Dr. Osama Shekhah winning for his work on MOF thin films. Why it matters: Such collaborations between Saudi and international universities help to foster knowledge exchange and address global challenges in key areas like materials science and sustainable energy.
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 Discovery Professor Tao Wu's research focuses on oxide thin films and nanomaterials for applications in spintronics, nonvolatile memory, energy harvesting, and sensors. His group aims to develop oxide thin film heater structures by combining different materials at the unicell level to create new artificial materials. The main technical areas involve spintronics, electric field effect devices, and oxide solar cells, leveraging Saudi Arabia's abundant solar energy. Why it matters: This research could lead to next-generation electronic devices and solar cells using more stable and versatile oxide-based solutions, aligning with Saudi Arabia's renewable energy goals.
