Journal Club January 2010: MEMS-based Instrumentation for Experimental Nanomechanics

Submitted by Yong Zhu on

Welcome to the January 2010 issue! In the issue of May 2007 , Prof. Xiaodong Li outlined the existing experimental methods for mechanical characterization of 1D nanostructures. In this issue, I will discuss along the same line but focus on experimental methods enabled by microelectromechanical systems (MEMS).

van der Waals interaction controls orientations of single-walled carbon nanotubes on quartz during growth

Submitted by Jianliang Xiao on
Single-walled carbon nanotubes (SWNTs) possess extraordinary electrical and mechanical properties, with many possible applications in electronics and materials science. Dense, horizonally aligned arrays of linearly configured SWNTs represent perhaps the most attractive and scalable way to implement this class of nanomaterial in practical systems. Recent work shows that templated growth of tubes on certain crystalline substrates (e.g. quartz) yields arrays with the necessary levels of perfection, as demonstrated by the formation of devices and full systems on quartz.

Welcome to new background of micromechanics

Submitted by Valeriy Buryachenko on

Dear Colleagues,

 I am please to let you know about the birth of a new background of micromechanics defining a new field of micromechanics called computational analytical micromechanics (CAM). It offers opportunities for a fundamental jump in multiscale research (see the abstract attached, where avalable electronic publications are indicated and encouraged for reading). However, these opportunities can be realized only in the case of joint efforts of both computational micromechanic's society and the analyticalone. I would be happy if CAM piques your attention.

Experimental Observations of Stress-Driven Grain Boundary Migration

Submitted by Tim Rupert on

My coworkers (Dan Gianola, Yixiang Gan, and Kevin Hemker) and I have published research results in the December 18th, 2009 issue of Science.  In this work, we perform tension tests on specially designed thin film samples to studying the influence of different stress and strain states on mechanically-induced grain growth in nanocrystalline aluminum.  Our results indicate that shear stresses drive grain boundaries to move in a manner consistent with recent molecular dynamics simulations and theoretical predictions of coupled grain boundary migration.
