Probing the intermediate states between rolling-up and wrinkling thin films

Self-positioned nanomembranes such as rolled-up tubes and wrinkled thin films have been potential systems for a variety of applications and basic studies on elastic properties of nanometer-thick systems. Although there is a clear driving force towards elastic energy minimization in each system, the exploration of intermediate states where specific characteristics could be chosen by a slight modification of a processing parameter had not been experimentally realized.

Piezoelectricity above the Curie temperature? Combining flexoelectricity and functional grading to enable high-temperature elect

Most technologically relevant ferroelectrics typically lose piezoelectricity above the Curie temperature. This limits their use to relatively low temperatures. In this Letter, exploiting a combination of flexoelectricity and simple functional grading, we propose a strategy for high-temperature electromechanical coupling in a standard thin film configuration.

Symposium in IMECE 2014, Montreal, Canada

Experiments in anti-plane deformation of thin films

Dear all,

I was curious whether there are any
experimental information and / or results regarding the out of plane (anti-plane)
deformation of (very) thin films. 
For example an elastic thin film subjected to anti-plane loading on its surface. Any other suggestions regarding possible applications of anti-plane loading conditions in thin films would be appreciated. 


Thanks a lot,

Post Doctoral Appointment in Thin Film and Grain Growth Modeling

Professor Gregory B. Thompson at the University of Alabama seeks post doctoral applicants for thin film and grain growth modeling in metal alloys. The qualified candidate will use modeling to explain and help direct experimental studies.

Postdoctoral Positions in MicroPhysiological Systems

We have several postdoctoral positions opening now and in the coming months. We are especially interested in candidates with backgrounds in theoretical biomechanics who are interested in conducting bench experiments. These positions will focus on our efforts to recapitulate organ-level function on microchips for drug discovery and physiological studies.

A kinetics approach to surface wrinkling of elastic films

This chapter summarizes our works on surface wrinkling of elastic thin films, taking a kinetics approach as a physical pathway to both ordered and disordered wrinkle patterns.

Profilometers using Low Coherence Interferometry used by NASA to measures thickness

Using a fiber-based optical profilometer NASA measures the thickness of liquid nitrogen in cryogenic chambers at its Propulsion Systems lab because these profilometers use fiber-based probes which can withstands the extreme environment, can be located hundreds of meters away from the interferometer and fit in the tight chamber which standard full-field profilometers with a human operator could not. The signal quality stays constant over the distance.

The surface effect on the strain energy release rate of buckling delamination in thin film–substrate systems

Gurtin–Murdoch continuum surface elasticity model is employed to study the buckling
delamination of ultra thin film–substrate system. The effects of surface deformation and
residual stress on the large deflection of ultra thin film are considered in analysis. A
concept of effective bending rigidity (EBR) for ultra thin plate is proposed on the basis of
Gurtin–Murdoch continuum theory and the principle of minimum potential energy. The
governing equations with EBR are formally consistent with the classical plate theory,
