Time: 4:00 – 5:30pm March 30, 2015 (Monday)

Location: Lecture hall, College of Chemistry and Chemical Engineering.

Professor Konstantin Novoselov:

Professor Konstantin ‘Kostya’ Novoselov was born in Russia in August 1974. He is best known for isolating graphene at the University of Manchester in 2004, and is an expert in condensed matter physics, mesoscopic physics and nanotechnology. He graduated from the Moscow Institute of Physics and Technology, and undertook his PhD studies at the University of Nijmegen in the Netherlands before moving to the University of Manchester with his doctoral advisor Andre Geim in 2001.

Professor Novoselov was awarded the Nobel Prize for Physics in 2010 for his achievements with graphene. Kostya holds positions of Honorary Professor of Physics and the Royal Society Research Fellow at the University of Manchester. He has published more than 180 peer-reviewed research papers. He was awarded with numerous prizes and was knighted in the 2012 New Year Honours.

Prof. Novoselov, paid his fifth visit to XMU to share his latest research findings on graphene, and presented his second lecture in XMU, following the lecture, "graphene application technology seminar" on February 20, 2014. Prof. Konstantin Novoselov developed close corporative relationship with iChEM and Industrial Graphene Institute of Technology, China.

Abstract:

In his lecture, Prof. Konstantin Novoselov, presented an elaborative talk on the topic “Graphene, other 2D materials and their heterostructures.” Graphene is a two-dimensional film material with only one carbon atom thickness. With its multiple superior features, graphene has become one of the hotspots of today’s scientific research. He explained that invention of graphene has opened a floodgate of experiments on many other 2D atomic crystals: BN, NbSe2, TaS2, MoS2, etc. Strategies applied to graphene can be replicated to obtain new materials by mechanical or liquid phase exfoliation of layered materials or CVD growth. An alternative strategy to create new 2D crystals is to start with an existing one (like graphene) and use it as an atomic scaffolding to modify it by chemical means (graphene and fluorographene are good examples).

Nature provides us with many other 2D crystals, such as boron nitride and molybdenum disulphide. Being structurally related to graphene but having their own distinctive properties, they offer the possibility of fine-tuning material and device characteristics to suit a particular technology better or to be used in combination with graphene (for example, 2D-based heterostructures). Being part of such a large and diverse family of 2D crystals and heterostructures will improve graphene’s chances of commercial success.

Graphene popularly known as the "miracle material" is expected to bring innovation to touch screen, energy storage, electronics, sensors, biotechnology and other areas. He mentioned that through the understanding of two-dimensional materials, the relative subject such as materials, chemistry, physics, micro-nano and energy will have further new enhancements in industry sector. Also, it is estimated that global graphene industry will make more than 100 billion US dollars over the next 5 to 10 years.
