It is well known that metals are hardened by deformation and soften by annealing. How about nanostructured metals? Can we reply on conventional metal-working lore?

The Max Planck Society (MPS) aims at promoting young international scientists by enabling them to perform their research (in all fields pursued by the MPS) at a Max Planck Institute of their choice.

The MPS offers Independent Junior Research Group Leader positions (W2; equivalent to associate professor level without tenure) granted for a period of 5 years with the option for prolonging twice for 2 years. The deadline for application is January 10, 2007.

Hello everyone,

Professor Suo suggested that I share this speculative idea that I once posted on Applied Mechanics News here on iMechanica!

In the future, we would like to reach out to children as early as their elementary school years to get them excited about topics drawn from Applied Mechanics. One approach to this goal takes inspiration from the successful "Le main a la pate", or "hands-in-dough", program in France (http://www.lamap.fr/ ), but extends the idea of hands-on science to take advantage of the internet.

In this study, bone cells were successfully cultured into a micropatterned network with dimensions close to that of in vivo osteocyte networks using microcontact printing and self-assembled monolyers (SAMs). The optimal geometric parameters for the formation of these networks were determined in terms of circle diameters and line widths. Bone cells patterned in these networks were also able to form gap junctions with each other, shown by immunofluorescent staining for the gap junction protein connexin 43, as well as the transfer of gap-junction permeable calcein-AM dye.

If you are interested by the computational aspects of fracture and failure of materials and structures,there is a dedicated conference for you : CFRAC 2007, which will be held in Nantes, France, 11-13 June 2007. It is an thematic conference of the European Community in Computational Methods in Applied Sciences (ECCOMAS). The for abstract is now closed. This conference wil involve a certian number

When a metal is grown onto a substrate of itself (homoepitaxy), the growth front is typically smooth, or at most is roughened by the formation of shallow hills (called surface mounds). The underlying reason for the roughening has been recognized to be of kinetic nature: Atoms landed on an upper terrace do not have enough time to overcome the "road blocks" provided by the steps and fill all the valleys (known as the Villian instability).

A new journal dedicated to the field of Molecular and Cellular Biomechanics has been formed for about a year. Many members in this community (such as Ning Wang, Cheng Zhu, Phil LeDuc) are on the board of editors. You may want to check it out....
