A post-doctoral research associate position is available immediately in the Department of Mechanical Engineering, and Maryland NanoCenter at the University of Maryland, College Park, in the area of multi-scale modeling (from atomistic, molecular, coarse-grained to continuum) of carbon-based nanostructured materials. Material properties of specific interest include mechanical and electrical properties, with special focus on deformation/failure mechanisms and bandgap engineering. 

A Ph.D. in solid mechanics, materials science, physics or a related field is required. The candidate should have well-developed multi-scale modeling and simulation skills, established publication record, and strong verbal/writing communication skills.

Obama spoke at the National Academy of Sciences on Apr. 27, 2009, in which he states his commitment to doubling of science funding and stem education. From his speech,

 "At such a difficult moment, there are those who say we cannot afford to invest in science, that support for research is somehow a luxury at moments defined by necessities.  I fundamentally disagree.  Science is more essential for our prosperity, our security, our health, our environment and our quality of life than it has ever been before."

You may also find a recent pertinent discussion in iMechanica interesting.

Stop Trying To Get Tenure and Start Trying To Enjoy Yourself

One of my junior colleagues forwarded the above article to me, and I read with interest. I think it could also resonate the interest of many people here in iMechanica. I welcome your comments, especially from our been-there done-that tenured colleagues.

Giving presentations at conferences or seminar series is a vital part of a researcher's professional life.  Listening to others' presentations is also one of the best ways to stay current with the frontier of a research field. While the audience in conference/seminar room is often limited, a presentation posted online can be virtually viewed by any interested audience. At iMechanica, users have started to post their presentation slides, quite often as the attachments of a post briefing the presentation.  Such a way is simple and effective, but may not be the best way for everyone for the following reasons:

We study the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer-supported metal films agrees well with the simulation results.

Dear fellow iMechanica users,

Many of you have experienced unstable access to iMechanica recently.  To our best knowledge, such unstable performance can be related to the fast-growing user volume of iMechanica. We have been working with Lesley Lam at OIT of Harvard School of Engineering and Applied Sciences to cure such growing pains of iMechanica.  We apologize for any inconvenience due to unstable access to iMechanica, and appreciate your understanding while we're working on this issue.  The support from all of you has been vital to iMechanica since day one and will continue to be so for the years to come.

The number of registered users of iMechanica reaches 7000 on 11 May 2008. So far, our fellow iMechanicians have contributed 3172 posts and 7425 comments.  The evolving statistics of iMechanica
(see the latest updates here and here) shows a steady growth with no sign of slowing down. 

Check out the earlier milestones of iMechanica when the number of registered users reached:

Dear fellow iMechanicians:

After some technical problems over the past weekend, iMechanica is now back on full service. We apologize for any inconvenience this may cause and thank for your patience.

We are particularly grateful to Ms. Lesley Lam in OIT of Harvard School of Engineering and Applied Sciences for her prompt fix of the problem.

Well-known for its high yield strength, metallic glass often suffers from its low ductility and intrinsic brittleness, as discussed in a recent iMech jClub theme on plasticity and failure in metallic glasses led by Yanfei Gao.

As the most rigid cytoskeletal filaments, microtubules bear compressive forces in living cells, balancing the tensile forces within the cytoskeleton to maintain the cell shape. It is often observed that, in living cells, microtubules under compression severely buckle into short wavelengths. By contrast, when compressed, isolated microtubules in vitro buckle into single long-wavelength arcs. The critical buckling force of the microtubules in vitro is two orders of magnitude lower than that of the microtubules in living cells.

At 71, Physics Professor Is a Web Star

Most frequently e-mailed by NYTimes.com readers in the past 30 days, the above article features MIT physics professor, Walter H. G. Lewin, on how his free physics lecture videos online have won him devotees all over the world.

While preparing a talk on iMechanica , I came across the following video "Information R/evolution" by Michael Wesch, an assistant professor of anthropology at Kansas State University.  This thought provoking video echoes a recent comment on "The future of knowledge?"

Enjoy!

Attending conferences is one of the essential professional activities for scientific researchers. Conferences take various forms, such as community-wide meetings (e.g., MRS meetings, ASME congress, APS meetings), and topic-focused meetings/workshops (e.g., Plasticity07, Gordon Research Conferences(GRC)).  While people have different preferences on the types of conference to attend (e.g., see a recent iMech poll initiated by Biswajit Banerjee ), here are some common positive driving forces to motivate one to attend a conference:

On September 20, 2007, Harvard School of Engineering and Applied Sciences (SEAS) was officially launched .   SEAS emeritus Gordon McKay Professor of Systems Engineering and T. Jefferson Coolidge Professor of Applied Mathematics,  Yu-Chi Ho, wrote a blog entry about the history of Harvard engineering.  Interesting to we mechnicians is that the original benefactor Mr. Gordon McKay specified in his will that his huge furtune is to be used to support " mechanical engineering and related arts". As a result, the first strong group established was the applied mechanics group.

Prof. Ho's blog entry is available at:

From Prof. Jaydev P. Desai at University of Maryland:

The number of registered users of iMechanica exceeded 3000 today, three months after iMechanica welcomed its 2000th user.  The number of posts has exceeded 1700, and the number of comments, 3800. The growth of iMechanica has been stable and amazing, leading to a natural question: why do people register at iMechanica? iMechanica is open:  evevryone can read everything without registration.  You can post anything of interest to mechanicians once you register for a free account. 

On 6 June 2007, about 50 mechanicians attended a special session at the McMat 2007, "iMechanica.org get together". The attendees of this special session came from various job sectors, such as academia, industry as well as government agencies. The session was chaired by K. Ravi-Chander and Rui Huang, who also served in the organizing committee of McMat 2007.
