Environment
The post-doctoral position will be accomplished within the BATir (Building, Architecture & Town planning) department of the Brussels School of Engineering/´Ecole polytechnique de Bruxelles, at the Universit´e Libre de Bruxelles (http://batir.ulb.ac.be ). Duration of the position: 18 months, starting in April 2012.
Profile
Why should we investigate fracture and failure mechanics? From this Boeing 737 accident (below) to recent fatigue cracks of new Airbus A380, we must use failure mechanics knowledge to save our lives. Therefore, Dr.H. Eliot Fang (Program Manager at the DOE Sandia National Labs), Dr. Larry
C. Russell (program manager at the Army Research Office) and I would invite you to submit abstracts to our symposium
The Fifth IFAC Symposium on Fractional Differentiation and Its Applications - FDA12

This paper reports the quantitative measurement of a full spectrum of mechanical properties of fivefold twinned silver (Ag) nanowires (NWs), including Young’s modulus, yield strength, and ultimate tensile strength. In-situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young’s modulus, yield strength, and ultimate tensile strength all increased as the NW diameter decreased.
We systematically investigated the interesting electric response of the aligned CNT ribbons under mechanical strain. We found that CNTs slide on a PDMS substrate under tension, but buckle under compression (releasing). Such an irreversible mechanical deformation is responsible for the observed irreversibility in the electric resistance upon the first stretching/releasing.
A postdoctoral position is available in the Computational Mechanics and Materials
Group within the School of Civil and Environmental Engineering at Cornell
University (http://ceeserver.cee.cornell.edu/dhw52/index.shtml).
The project will involve the application of ab-initio atomistic modeling
techniques to illuminate the mechanisms by which impurities and environment
influence the mechanical failure of engineering materials.
I was looking for some decent presentations on Rare Metals, and was at a loss in finding some. It would be great if anyone could direct me to anything related to rare metals, especially on presentation form. My email is rummantdm [at] yahoo.com.
