CV

 

Prof. Lianxi Zheng received his BE degree on Electronic Engineering from Southeast University (China), and his PhD 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 in Khalifa University (UAE). He 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 36, and chaird 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

  • “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 and optimize a new generation of multifunctional smart glazing materials via a novel hybrid approach, which would allow the smart windows to efficiently switch from a transparent state to a tinted state in response to sunlight (photochromic effect) and external temperature (thermochromic effect), and to have self-cleaning/anti-fogging abilities.

  •  “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.

  • “Development of Graphene-Based Energy Storage Devices” [AED 2,042,210, KUIRF L2, Co-I (PI: Kin Liao), 2016-2017]: to use graphene to design and fabricate a new generation of high performance energy storage devices including lithium batteries, super-capacitors, and flexible energy devices, aiming to provide energy devices with high energy density and high power density, and to offer deformable energy devices for applications in wearable and portable electronic products.

  •  “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.

  • “Develop super-strong and multifunctional carbon-nanotube-fiber reinforced composites” [KU-KAIST seed Fund, PI on Khalifa side (PI in KAIST: Lee, Haeng-Ki), 2015-2016]: This project brings together the world-leading and complementary expertise available from the UAE and Korea to develop multifunctional CNT fiber-reinforced composites which exhibit mechanical properties significantly improved as compared to existing fiber-reinforced polymers (FRPs) to therefore facilitate stress/strain and damage detection.
