The team is working on sustainable polymeric materials, including rethinking tire composition to improve recyclability and reduce pollution. Why it matters: This research contributes to developing more sustainable plastics and polymers, addressing a critical environmental challenge while advancing materials science 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.
Aramco and KAUST have launched the ENERCOMP consortium, a five-year initiative focused on R&D in nonmetallics and composites for energy applications. Aramco is the founding member and first research sponsor. The consortium aims to develop less energy-intensive and lower carbon-footprint materials, aligning with Saudi Arabia's sustainability vision. Why it matters: The partnership signals a strategic push towards diversifying the Kingdom's economy and strengthening its position in the energy and materials transitions, leveraging AI and advanced materials research.
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 Ph.D. student Hui-Chun Fu and postdoctoral fellow Purushothaman Varadhan won awards at the 2018 NANO Conference in Hong Kong for their photoelectrochemical research. They received the Materials Today Rising Star Poster Award (Silver) and the NANO2018 Session Theme Poster Award. Their research focuses on converting solar energy into storable fuels like hydrogen through solar-driven water splitting. Why it matters: This recognition highlights KAUST's contributions to renewable energy research, crucial for the GCC's transition to sustainable energy sources.
