Zeng, Xiangbing - University of Sheffield - Department of Materials Science and Engineering

个人简介

Xiangbing Zeng was appointed as Lecturer in Polymers and Liquid Crystals in October 2003. Previously he was a research assistant in the Polymer, Liquid Crystal and Supramolecular Structures Group in this department. He obtained his PhD degree from the University of Sheffield in 2001.

研究领域

Dr Zengs' research areas can be divided into two broad directions: one on polymer physics, in particular the polymer crystallization process; the other on self-assembly, which covers systems such as supra-molecules, liquid crystals, more recently LC covered nanoparticles. On the polymer side, he is involved in an eight-institution international collaboration supported under NSF-EPSRC Pire scheme, for developing new materials from natural sources for applications in sustainable energy industry. On the self-assembly side, a research project on “Liquid quasicrystals and their approximants”, supported by Leverhulme trust, started in 2013. Another important aspect of his research on self–organized systems is to develop new nano-materials for tailored optical and electrical properties. For example, metamaterials by self-assembled gold nanoparticles have been fabricated, by covering them with liquid crystal forming molecules. Dr Zeng has ample experience with scattering methods (X-ray and neutron) for characterization of nanoscale structures, which often involve the use of large scale facilities such as synchrotron radiation sources (e.g. Diamond, ESRF) and neutron sources (ISIS, ILL). Other microscopic (optical, SEM, TEM, AFM) and spectroscopic (FTIR, UV-Vis, Raman etc) methods are employed whenever necessary.
