So far, Dr Zhan has 56 journal articles and 2 invited book chapters. His research has been published in prestigious journals (e.g., Nature Communication, Advanced Functional Materials, Nanoscale), and featured by renowned national and international medias, such as MIT Technology Review, PHYS. ORG, and Chemistry in Australia.
报告摘要:
The advancement of nanotechnology has introduced a grant change to the broad field of engineering in the past decades, which has enabled the design and manufacturing of devices/materials from the bottom, the inspections of observations/phenomena from the bottom. We’ve witnessed the increasing progression of additive manufacturing (e.g., 3D printing), the wide spread applications of composites and carbon fibers in replacing traditional metals/alloys to reduce the weight of machines, the increasing usage of renewable energy, and others. This talk will first discuss the intriguing mechanical and thermal properties of low-dimensional nanostructures (including 1D, 2D and 3D nanomaterials) as acquired from atomistic simulations. Examples will be given to show how the continuum mechanics are adapted to describe the nanoscale mechanical behaviour [1], and how the thermal transport can be tailored at nanoscale [2] .Emphasis will then be put on the engineering applications and perspectives of nanostructures by taking carbon-based material as an example. Discussions will cover the failure behaviours of graphene under high-speed projectile targeting surface protection or anti-penetration applications [3], the application of diamond nanothread as reinforcement for polymers [4], the fiber interfacial properties [5] , and other engineering applications.
