Professor, Department of Mechanical Engineering

Dr. Lianxi Zheng received his BEng degree on Electronic Engineering from Southeast University (China), and his Ph.D. on Physics from the University of Hong Kong. He worked in Los Alamos National Laboratory as a Director’s Postdoctoral Fellow, CNT Technologies Inc. as a Research Scientist, Nanyang Technological University as an Assistant Professor, and now is a Full Professor at Khalifa University (UAE).

Dr. Zheng has made several significant contributions in the area of nanomaterials, among which is his invention of a chemical-vapor-deposition method to make world-record long (40mm) SWCNTs. During his career, he has gained several awards including 2 Nano 50 Award from NASA, licensed 3 US patents, published over 150 journal papers with an H-index of 38, and chaired many conference sections. He was the treasurer and a committee member of IEEE Nanotechnology Chapter (Singapore section), and has been a member of editor boards for several scientific journals. His current research activities are focused on studying carbon nanomaterials and their hybrids, targeting to the applications of flexible & smart devices, photocatalysis, energy harvest & storage, artificial muscle, e-textile, nano mechanics, and nano-electronics.

Recent Research Projects

  • “Flexible & smart textile architectures with integrated tactile sensor arrays and memristive networks for robotic applications” [AED 2,739,164, CIRA-2020-24, PI, 2020-2023]: to develop a flexible & smart textile architecture with sensing, signal-processing, and self-learning functions for robotic applications. The sensing unit is composed of both in-plane tensile sensors and out-of-plane compressive sensors that can provide 3D stress/strain distributions, and the memristive network is able to recognize these signal patterns after training. The combination of both offers true smart functions without computation, enabling tremendous advances in the areas of artificial intelligence & robotics.

  • “Development of smart glass with self-cleaning and infrared-shielding properties for energy-efficient buildings” [AED 2,299,348, CIRA-2018-03, Co-I (PI: Giovanni Palmisano), 2018-2021]: to develop 2D materials based Z-scheme photo-catalyst systems and immobilize them on glass for environmental remediation. The artificial Z-scheme is constructed by two photosystems, one having strong oxidative holes while another having strong reductive electrons. Both photosystems are designed and fabricated in 2D morphologies and with visible-light band-gaps, so that the resultant Z-scheme catalysts can possess efficient light absorption, effective charge separation, and high redox capabilities at the same time.

  •  “Highly stretchable and torsionable supercapacitor for wearable electronics” [AED 1,743,814, KUIRF L2, PI, 2017-2018]: to develop fiber-shaped flexible supercapacitors that can provide stable energy storage even under severe stretching and torsional deformations. These stretchable & torsionable supercapacitors will be fabricated from newly designed shearable-carbon-nanotube films, which have unique microstructures that allow them to translate the torsional deformation into shear strain, and then accommodate such a strain through nanotube sliding, without degrading the mechanical and electrical integrity.

  •  “Super-strong and multifunctional carbon-nanotube-fiber reinforced composites for aerospace applications” (AED 1,717,640, KUIRF L2, PI, 2014-2016): to study/develop a new class of composite that offers an outstanding structural performance combined with continuous structural health monitoring and on-line damage detection. This new composite material is based on high-performance carbon-nanotube (CNT) fibers, which are stronger and lighter than the carbon fibers that are currently used in aerospace applications.
