Journal Club Theme of March 2013: Interfacial Adhesion of Graphene - Measurements and Analysis

Several recent papers have reported measurements of adhesion energy between graphene and other materials (e.g., Si/SiOx and copper) [1-3]. Like thin films, many experimental methods may be adopted to measure the interfacial properties of graphene, such as the pressurized blister test [2] and the double-cantilever beam test [3]. The challenges lie in the handling of atomically thin membranes and analysis/interpretation of the data.

An atomistic-based foliation model for multilayer graphene materials and nanotubes

The mechanical behavior of mono- and multi- layered graphene and carbon nanotube (CNT) systems has attracted great attention over the last decade because of their importance in nano-science and nanotechnology.

We have presented a new bulk atomistic-based continuum model for layered crystalline materials made out of two- dimensional crystalline sheets. Such systems are emerging as a new family of materials with tunable and exceptional properties (Novoselov K., 2011, Nobel lecture: Graphene: materials in the flatland. Rev. Mod. Phys. 83, 837-849), but here we particularize the model to multi-layer graphene systems, including multi- walled carbon nanotubes (MWCNTs).

Book "Simulations in Nanobiotechnology"

I am happy to announce the publication of a book "Simulations in Nanobiotechnology", which was contributed from researchers (including iMechanicians) who have expertise in the area of nanobiotechnology. The book is aimed at presenting the current state-of-arts in computational simulations of biological objects such as proteins as well as nanomaterials such as graphene, and also bio-nano-hybrid system such as nanopore-biomolecule interactions. This book provides the insight into the simulation-based characterization in nanobiotechnology.

Determining Graphene Adhesion via Substrate-regulated Morphology of Graphene

Understanding the adhesion between graphene and other materials is crucial for achieving more reliable graphene-based applications in electronic devices and nanocomposites. The ultra-thin profile of graphene, however, poses significant challenge to direct measurement of its adhesion property using conventional approaches. We show that there is a strong correlation between the morphology of graphene on a compliant substrate with patterned surface and the graphene-substrate adhesion.

Postdoc position at MIT available immediately

We have several open postdoc positions, to be filled immediately.

The first project is focused on thermal management. The project involves the computational and theoretical analysis of graphene/graphite-metal nanocomposites and experimental work carried out by other team members. We are looking for a strong person with background in thermal and mechanical properties of materials, preferrably with background in molecular simulation.

For the other projects we are looking for candidates with expertise in mechanics of materials. Our projects are specifically focused on molecular and coarse-grain modeling of deformation and failure of soft biological materials and include a focus on collagen, spider silk, amyloid materials and other biomaterials.

Physicists Won 2010 Nobel Prize for Discovery of Graphene

As announced on 5 Oct. 2010,  Andre Geim and Konstantin Novoselov of the University of Manchester won the 2010 Nobel Prize in physics "for groundbreaking experiments regarding the two-dimensional material graphene". Geim and Konstantin first reported the experimental observation of graphene in 2004 .  Novoselov, 36, is also the youngest physics laureate since 1973.

Postdoc position at MIT: Thermal and mechanical properties of nanocomposites

A postdoctoral associate position at MIT is available immediately,
focused on the analysis and development of multifunctional thermal

modeling and simulation. This project specifically involves calculations
of thermal and mechanical properties of graphene based metal- and
polymer nanocomposites, with a focus on various aspects such as
interfacial transport properties, tunability, mutability and phonon
engineering. Additional aspects of the project relate to the general
area of mechanical energy transport in biological materials.
