The plausibility of <c + a> dislocation slip on {-12-11} planes in Mg
Dear Colleagues,
Please see the link for a recent article published in Scripta Materialia. In this article, active cross-slip behavior of screw <c + a> dislocations in Mg is observed, and the plausibility of <c + a> dislocation slip on new planes {-12-11} that have hitherto not been considered possible, is shown for the first time.

Fully Funded Ph.D. Position
A Ph.D. position is available in the Mechanical and Aerospace Engineering Department at the University of Alabama in Huntsville starting Spring Semester 2019. The focus of the project is on the performance enhancement of aerodynamic systems using fluidic and smart material actuators such as piezoelectric-based synthetic jets and micro fiber composites.
Gradient elasticity theory for fiber composites with fibers resistant to extension and flexure
A model for the mechanics of an elastic solid, reinforced with bidirectional fibers is presented in finite plane elastostatics. The fiber’s resistance to stretch and flexure are accounted for with variational computations of first and second gradient of deformations, respectively. Within the framework of strain-gradient elasticity, the Euler equation and necessary boundary conditions are formulated. A rigorous derivation of the corresponding linear theory is also developed from which, a complete analytical solution is obtained for small deformations superposed on large.

3-Year Postdoctoral Fellow: Green Chemistry/Materials Chemistry
The required postdoctoral fellow will play a leading role in performing research leading to high-impact publications in the broad field of materials chemistry/crystal engineering. The postdoctoral fellow is expected to possess strong experimental research skills and ideally some computational materials modelling experience. The right candidate will spend most of their time in the laboratory where he/she will utilize their strong expertise in synthesis (organic or inorganic compounds) and materials chemistry/characterization in order to develop and validate a novel biosurfactant catalyzed mechanochemical remediation method for the green synthetic functionalization and conversion of persistent organic pollutants. In addition to performing research leading to high-impact publications in peer-reviewed materials chemistry journals, the postdoctoral fellow will work as part of a multidisciplinary team of molecular biologists, bioinformatics experts, chemists and chemical engineers in order to facilitate the deliverables of this exciting project.
