We seek a full-time Ph.D. student to work on the transmission electron microscopy (TEM) of nickel-based superalloys in the Department of Mechanical Engineering at the University of Alabama. The position will start in January 2021 and will be for four years. It will be funded through a new NSF project on surface engineering of the nickel-based superalloys. The goal is to explore and understand the strengthening and precipitate interactions.

An immediate Ph.D. position is available in the Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of materials synthesis. The candidates must have earned a degree in Mechanical Engineering, Chemical Engineering, or related fields (applicants with an MSc will be given priority) and have a solid background in theoretical and computational mechanics. Having knowledge of continuum mechanics, finite element modeling, and a programming language is a plus. 

A fully supported Ph.D. position is open in the Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of additively manufactured parts and processes. During this project, the candidate will have the opportunity to collaborate with NASA research centers and national labs.

A special issue of Journal of Nanomaterials is devoted to "Low-Dimensional Phase Transforming Materials" which obtained significant interests in the recent years. This topic covers a broad range of research such as 

A nanocomposite electrical generator composed of an array of zinc oxide nanowires is considered.
The electric potential distribution along zinc oxide nanowires is modeled using continuum
mechanics and Maxwell’s equations for the case of axial loading. A perturbation technique is used
for decoupling the constitutive equations. The governing differential equations are solved using a
finite difference method. It is shown that a gradient of electric potential exists along the axis of the
zinc oxide nanowires. Maximum and minimum values of electric potential exist at the extreme ends
along the nanowire length and have opposite signs. The positive and negative voltages are separated

I have formulated a shear-lag model for calculating the variation of stress along carbon nanohorns (CNHs), which are conical shaped wrapped carbon sheets, embedded in an epoxy matrix under axial loading.  I found that the stress distribution along the length of CNHs depends on the cone angle of these structures and maximum normal axial stress has a smaller value in CNHs compared to a carbon nanotube (CNT) with same cross-section as of the CNH's tip.  Furthermore, I read an article stating that synthesis of CNHs are easier compared to CNTs.  However, the only article I could find which has s
