In-surface Buckling of Silicon Nanowires on Elastomeric Substrates

Submitted by Jianliang Xiao on

Buckling of thin layers or aligned arrays of stiff materials on elastomeric substrates has many important applications, such as stretchable electronics, precision metrology and flexible optoelectronics.  These systems show one common phenomenon, the stiff thin layers buckle normal to the substrate surface (out-of-surface buckling).  By contrast, we recently reported for the first time that silicon nanowires (SiNWs) on elastomeric substrates buckle only within the substrate surface, i.e. in-surface buckling.  Experimental process to obtain buckled SiNWs is described.

Food for Thought: A Few Recent arXiv Papers

Submitted by Ajit R. Jadhav on

Since my research touches on the basics of QM, I have developed this habit of visiting arXiv.org every now and then. Last week or so, at arXiv.org, I found a couple of interesting articles on physics in general. I would like to share these with you.

Postdoctoral Scholar Position in Modeling Li-Ion Batteries

Submitted by guofengwang on

A postdoctoral research position in the modeling of failure mechanisms for lithium ion batteries is available immediately at the Richard G. Lugar Center for Renewable Energy in Indiana University-Purdue University Indianapolis (IUPUI). The candidate will work on the study of failure mechanisms of lithium ion batteries which are related to lithium ion diffusion, heat generation and transfer, chemical reaction, and stress development inside the battery.

Convergence test in ANSYS

Submitted by gohelvivek on

Hi, i tried to solve a simple plane stress cantilever problem using ansys but it did not converged to the exact value and it goes beyond the exact value for stress and diplacment domain as i go on making finer mesh. the problem is as shown below, i tried 4 noded solid plane82 and 8 noded plane 182 element type. Can anybody tell me the procedure for convergence test in ansys
