AFM

The School of Engineering and Applied Science at the University of Pennsylvania invites applications for two full-time Postdoctoral Researcher positions in the laboratories of Prof. D.S. Srolovitz (https://www.seas.upenn.edu/directory/profile.php?ID=180) and Prof. Robert W. Carpick (http://carpick.seas.upenn.edu).

Dear Colleagues

The SES 50th Annual Technical Meeting will be held July 28-31, 2013 at Brown University (Providence, RI, USA).
I would like to invite you to submit an abstract to the symposium: "Experimental Nanobiomechanics", under Mechanics of Biological and Soft materials.

Animal cells behave like fluid-filled sponges in response to being mechanically deformed according to new research published in Nature Materials.

Scientists from the London Centre for Nanotechnology at UCL have shown that animal cells behave according to the theory of ‘poroelasticity’ when mechanically stimulated in a way similar to that experienced in organs within the body. The results indicate that the rate of cell deformation in response to mechanical stress is limited by how quickly water can redistribute within the cell interior.

Individual GaN Nanowires Exhibit Strong Piezoelectricity in 3D 

Colloidal nanocrystals (NCs) form a family of highly advanced building blocks suitable for large scale assembly of novel high-complexity 1D-to-3D superstructures. Their properties and inter-particle interactions, nowadays, can be highly controlled by tailoring their size, shape, composition and surface functionalization.

I would like to do lateral force microscopy on biological samples.  The more I look into it, it seems it is very difficult to calibrate AFM tips for lateral force microscopy.  Does anyone have any suggestions about how to calibrate tips and which tips are conducive for lateral AFM? 

As I promised, I start with some brief notes on themes loved by Ken Johnson to hopefully raise some interest for discussion on iMechanica. Regards, Mike
