Beverley J Inkson教授学术报告会
应物理科学与技术学院彭勇教授邀请,现任英国Sheffield(谢菲尔德)大学材料科学与工程系NanoLAB中心主任、兰州大学引进高端外国专家Beverley J Inkson教授将于11月28日至12月2日来我校访问并讲学,敬请关注!
报告题目:Real-time imaging of nanoscale electrical testing and tribology inside electron microscopes
报告时间:2012年11月29日(星期四)下午14:30
报告地点:校本部逸夫科学馆202报告厅
报告摘要: As material components shrink to the nanoscale, they can exhibit radically altered behaviour compared to bulk materials. However, it is difficult to assess the real-time behaviour and stability of individual nanostructured objects due to the complexity of simultaneously imaging and testing an object <100nm in size.
In this talk we will discuss new opportunities available for in-situ electrical and mechanical testing nanostructures inside electron microscopes, including a miniaturized TEM triboprobe which can apply cyclic loading and electrical stimulation to a nano-object. The NanoLAB Triboprobe has unique 3D control of the location of contact between two materials, applied shear direction, and cyclic loading profiles, which opens up the door for real-time nanofriction and nanofatigue testing.
Here we demonstrate the capability of the NanoLAB triboprobe with examples including (1) friction and electrically stimulated phase transformations in carbon, (2) real-time melting of solder materials, and (3) nanoscale liquid mechanics.
 
报告人简介:
Prof Beverley Inkson
Dept of Material Science and Engineering, University of Sheffield, UK
Prof Inkson was educated at Cambridge University, with a first class degree in Physics/Natural Sciences, and a PhD in Materials Science on the Nanostructure of  intermetallic alloys. After a Research Fellowship at Cambridge she moved to the Max Planck Institute for Metals Research, Stuttgart, Germany as an Alexander von Humboldt Fellow. She returned to the UK to Oxford University with a prestigious Royal Society Research Fellowship to set up a group in Nanomechanics, and moved to Sheffield in 2003, where she was appointed Professor in 2011.
Prof Inkson has extensive experience in the analysis of structural, mechanical and electrical properties of nanostructured materials, including a wide range of metal, ceramic and composite systems. Her work exploits the use of electron and ion microscopy to obtain nanomaterials properties, and she directs the Sheffield NanoLAB. She is particularly known for her development of 3D tomographic characterisation methods, and more recently developing novel in-situ measurement techniques to determine real-time dynamical behaviour of nanomaterials and nanoparticles under mechanical and electrical stimuli. This world-leading research has been partially supported by a ?3million EPSRC Basic Technology Programme.
