Mechanics of in-surface buckling of one dimensional nanomaterials on elastomeric substrates

Submitted by Jianliang Xiao on
In this recently published paper on Nanotechnology, we studied the in-surface buckling mechanics of one dimensional nanomaterials on elastomeric substrates.  Simple analytical solutions are obtained for buckling wavelength and amplitude, which can be easily applied to the in-surface buckling of different nanomaterials, such as nanowires and nanotubes.  It is shown that in-surface buckling of nanomaterials has lower energy than out-of-surface buckling, which explains the experimental observance o

Dear iMechanicians,



I have applied for the job of "Associate Professor" in the Department of Mechanical Engineering at COEP, Pune, India [^]---the same place from where I did my PhD (Mech.) research.



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.

Post-doctoral postion in Mechanical Engineering at NUS

Submitted by Shailendra on

I have an opening for a post-doctoral position starting early next year (Jan 2009) in the broad area of multi-scale mechanics of nano-crystalline (nc) materials. The focus will be on microstructure mediated failure processes in nc materials primarily using continuum mechanics based approaches, but informed by materials science.

If you are interested, please send me (shailendra[at]nus[dot]edu[dot]sg) your CV and the names of at least two references.

Thanks,

~Shailendra

Seeking Summer Internship Opportunity

Submitted by J. K. Phadikar on

I am a third year undergraduate student of IIT Kharagpur (www.iitkgp.ernet.in). In the coming summer, we are supposed to do summer training in some industry in, or out of India, whereas if we want to do internship in a university it must be a foreign university (internship in Indian universities is not allowed).
