Ripplocations = surface ripples + dislocations ?
Dislocations are topological line defects in three-dimensional crystals. Same-sign dislocations repel according to Frank’ s rule . This rule is broken for dislocations in van der Waals (vdW) layers, which possess crystallographic Burgers vector as ordinary dislocations but feature “ surface ripples” due to the ease of bending and weak vdW adhesion of the atomic layers. We term these line defects “ ripplocations” in accordance to their dual “ surface ripple” and “ crystallographic dislocation” characters.
PhD positions (TA/RA) available at Penn State
We are looking for PhD candidates to conduct research at the following two interdisciplinary subfields, starting from Spring of 2015. Interested individuals are encouraged to apply (suz10 [at] psu.edu)
1) Mechanics in electrochemistry. We develop atomistically informed continuum mechanics models, coupling mechanics and lithium reaction and diffusion to account for a wide range of in-situ experimental phenoemna. Some recent publications:
Research Assistant position available
My group in the Deaprtment of Engineering Science & Mechanics /Biomedical Engineering has an immediate RA opening, expected to start from the Fall of 2014.
The student of this position will be working on establishing computational mechanics models incorporating essential electrochemical details to study the performance and degradation of battery materials. We use both continuum theories as well as molecular dynamics as essential tools for simulations. The student will also have the opportunities to work with experimental team members on biomechanics.

Research assistant and postdoc positions immediately available
My research group in the Department of Engineering Science and Mechanics at Penn State has two immediate opennings, starting from Spring of 2011.
One position targets graduate assistant, who will be working on computational biomechanics and biophysics. However, highly qualified postdoc may also be considered.
The other position targets postdoc, who will be working on experimental single-cell mechanics, including nanoparticle-based drug delivery, cell responses to external mechanical stimuli, etc.
