KAUST researchers, in collaboration with KACST, discovered that dissolving nylon in battery electrolytes improves the performance of lithium-metal batteries. The nylon additive resulted in more efficient batteries with longer lifespans and fewer unwanted reactions. The research was published in ACS Energy Letters and Energy Environmental Science. Why it matters: This promises cheaper, safer, and more powerful lithium batteries for applications in electric vehicles and aviation, supporting Saudi Arabia's renewable energy goals.
KAUST Professor Nikos Hadjichristidis leads the Polymer Synthesis Laboratory, collaborating with Yves Gnanou to manipulate macromolecules at the nanoscale. They employ anionic polymerization using high vacuum techniques, a specialized method requiring handmade glassware and careful control. 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.
John Pantoja from the Directed Energy Research Center at TII presented a method to estimate the effects of high current impulses on electro-conductive textiles. The method uses specific action, a parameter to determine burst of exploding wires, and a new equivalent electrical circuit. The model estimates the current intensity needed to melt the conductive layer at contact areas between yarns, and is validated experimentally on ripstop woven fabrics. Why it matters: The research explores conductive fabrics for portable lightning protection shelters, potentially reducing lightning-related accidents in high-risk populations.
KAUST Ph.D. student Reem Alghamdi is working at the KAUST Catalysis Center to improve the quality of industrially used polyethylene. Her research focuses on synthesizing a nanocomposite of polyethylene and nanomaterials to reinforce industrially made polymers, improving their mechanical characteristics. The resulting hybrid organic-inorganic product minimizes manufacturing defects, enhancing hardness. Why it matters: This research has the potential to significantly improve the durability and performance of polymer products across various sectors, from automotive to construction, impacting numerous industries in the region and beyond.
KAUST startup Polymeron is converting date and poultry waste into biodegradable plastics, aligning with Saudi Vision 2030's goals for economic diversification and sustainability. The company aims to process 20,000 tons of waste annually, contributing to a circular economy and creating jobs in polymers, manufacturing, and sales. Polymeron is building its pilot plant at KAUST with support from the National Technology Development Program (NTDP). Why it matters: This initiative addresses plastic pollution and agricultural waste while creating a new industry in the Kingdom, tapping into a global market for biodegradable plastics valued at $13 billion in 2024.
KAUST's Center of Excellence for Renewable Energy and Storage Technologies (CREST) hosted a seminar on rechargeable hydrogen gas batteries. Professor Wei Chen from the University of Science and Technology of China (USTC) presented the seminar. The talk covered aqueous nickel-hydrogen gas, proton-hydrogen gas, halogen-hydrogen gas, and nonaqueous lithium-hydrogen gas batteries, along with applications like self-charging batteries. Why it matters: Hydrogen gas batteries represent a promising avenue for large-scale energy storage, particularly for integrating renewable energy sources into electric grids.
KAUST researchers led by Dr. Muhammad Hussain have developed a flexible, transparent silicon-on-polymer based FinFET inspired by the folded architecture of the human brain's cortex. The team created a 3D FinFET on a flexible platform without compromising integration density or performance. They aim to demonstrate a fully flexible silicon-based computer by the end of the year. Why it matters: This research could lead to the development of ultra-mobile, foldable computers and integrated circuits, advancing the field of flexible electronics in the region.
KAUST and Chinese companies Shandong Lianxin Environmental Protection Technology and Hangzhou Hecai Technology will manufacture green plastics based on KAUST technology. The plastics, high molar mass aliphatic polycarbonates, are for biomedical products and food packaging due to their biodegradability and biocompatibility. KAUST's method creates these polycarbonates using CO2 and sustainable raw materials without toxic metals, with production scaling over two years. Why it matters: This partnership highlights KAUST's role in developing sustainable materials and bringing them to market, with potential impact on reducing reliance on traditional plastics in sensitive applications.
