Speaker: Professor John Bell (Head of School, Chemistry, Physics and Mechanical Engineering, Queensland University of Technology, Brisbane, Australia)

Time:      10:30a.m, Oct. 13 (Monday) 
Location: Room 210, School of Materials Science and Engineering (MSE)
Abstract: Low dimensional materials have numerous unique attributes, such as ballistic electron tranfsport and high thermal conductivity in in carbon nanotubes and graphite.  The interactions between these carbon-based materials and conducting polymers can lead to nanoscale heterojunctions, and open up the possibility of nanoscale electronic devices.  The advantages of these type of electronic structures over traditional semiconductor devices are the possibility of large scale nanoelectronic device fabrication using self-assembly processes.  I will discuss the properties of graphene nanomaterials and how these might lead to a new generation of nanoelectronic devices.
This seminar will also provide a brief introduction of Queensland University of Technology and in particular the School of Chemistry, Physics and Mechanical Engineering. The focus of the School’s research is in the area of Materials Science and Engineering, with core strengths in chemical and physical synthesis of materials, surface science and computational modelling of materials.
Biography: Professor Bell has worked for nearly 25 years on thin film materials, with research on materials for energy efficiency in buildings, solar cells, sensors and hard coatings.  He is Head of School of Chemistry, Physics and Mechanical Engineering at Queensland University. He currently holds a Queensland Government Smart Futures Fellowship on the topic “Queensland’s Solar Future”, has published over 200 refereed papers, and secured over $18 million in research funding since 1990.  Prof. Bell has worked on dye-sensitized solar cells focussing on materials issues, modeling of the charge transport and extraction of power form DSC and other PV systems. He has also worked on a range of energy system modeling projects, including reducing electricity demand using advanced glazings and cool roof coating materials.  Prof. Bell is also a  Director of the Australian Nanotechnology Alliance.
