We studied the oxidation behavior of face-centered cubic Al0.3CoCrCuFeNi high entropy alloy through first-principles calculations. Three surface orientations were chosen for oxidation, and all the possible combinations of atomic positions at these surfaces were considered. The adsorption energy of oxygen adhesion to the studied surfaces was the lowest for the sites with more neighboring Cr atoms, and the second most favorite site for oxygen adsorption had more neighboring Al atoms.

A postdoctoral research associate opening with a primary focus on atomistic simulations of defects and mechanical behaviors of Mg and Mg alloys is available in Liang Qi’s group (http://cms.engin.umich.edu/) at University of Michigan, Ann Arbor. Qi’s group is involved in the PRedictive Integrated Structural Materials Science Center (PRISMS), a DOE-BES funded research center dedicated to integrated computational and experimental studies of structural alloys located at University of Michigan.

Link to our new paper outlining some strategies to steer interfacial debonding to a desired interface during a demolding process when the two interfaces in a 3-layer structure are equally weak. The article can be downloaded for free until July 5th. Would sincerely appreciate any feedback.

Abstract:

Several postdoctoral and graduate student openings with primary focus on biomechanics is available immediately in the Shenoy Research Group at the University of Pennsylvania. We are looking for strongly motivated candidates to work on NIH supported projects on a) cell-matrix interactions in fibrosis and cancer and 2) mechanical mechanisms of traumatic brain injury.

The University of Edinburgh and Williams Advanced Engineering is looking for an enthusiastic PhD candidate to develop novel, lightweight, high-performance composite structures and materials for application within multiple industry sectors.

A Cosserat rod based continuum approach is presented to obtain phonon dispersion curves of flexural, torsional, longitudinal, shearing and radial breathing modes in chiral nanorods and nanotubes. Upon substituting the continuum wave form in the linearized dynamic equations of stretched and twisted Cosserat rods, we obtain analytical expression of a coefficient matrix (in terms of the rod's stiffnesses, induced axial force and twisting moment) whose eigenvalues and eigenvectors give us frequencies and mode shapes, respectively, for each of the above phonon modes.

Applications are invited for PhD positions at the Algorithms in Medicine and Neuro-Technology Lab (AIMAN Lab) in the Department of Mechanical Engineering at George Mason University, Fairfax, VA. "Research" The AIMAN Lab pursues fundamental breakthroughs in biomedical cyber-physical systems.

There is an opening for a post-doctoral scholar in the Department of Materials Science and Engineering and the Hopkins Extreme Materials Institute at Johns Hopkins University.

The sacrum is the most susceptible anatomical site for developing pressure injuries (PIs), including deep tissue injuries, during supine lying. Prophylactic dressings are generally designed to reduce friction, alleviate internal tissue shear loads, manage the microclimate, and overall cushion the soft tissues subjected to sustained deformations under the sacrum.
