Dr. Giampiero Marchegiani from the Quantum Research Center (QRC) co-authored a paper in Nature Nanotechnology on bipolar thermoelectricity in Josephson junctions. The research demonstrates the generation of electrical current using heat, observing bipolar thermoelectricity where the device generates either positive or negative electrical signals without extra control. Integrating these junctions into a bipolar thermoelectric Josephson engine (BTJE) allowed the generation of up to ~140nW/mm2 of electric power at subkelvin temperatures. Why it matters: This BTJE engine may have applications in superconducting technology, potentially strengthening the UAE's position in quantum technologies.
KAUST startup Quantum Solutions manufactures quantum dots, semiconducting nanoparticles that emit light with controllable energy.

KAUST Associate Professor Aurelien Manchon has been appointed as the Wohlfarth Lecturer for the Magnetism 2020 conference. The conference, organized by IEEE UK Magnetic Chapter and the Institute of Physics, will be held in Sheffield, U.K. Manchon's research at KAUST focuses on spintronics and the development of high-speed, energy-efficient microelectronics. Why it matters: This recognition highlights KAUST's contributions to cutting-edge research in spintronics and magnetism, areas crucial for advancing microelectronics and data storage technologies.
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 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.
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 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.
