I am looking for three Ph.D. students who can work on molecular dynamics, finite element, and additive manufacturing of nanocomposites, ceramics, and polymers. In addition to these techniques, understanding of fracture mechanics, recycling, quantum dot synthesis, and machine learning is preferred. If you are interested, you can send your CV to [email protected].

Abstract Hybrid epoxy composites are highly considered for low-density applications due to the excellent specific strength and specific stiffness. Enhancements made to the epoxy matrix by addition of nanofillers like carbon nanotubes (CNTs) and graphene (GNPs) have been studied in detail over the course of few decades. These enhancements not only help elevate the material […]

Postdoctoral researcher Dr. Prathamesh Deshpande presented our research on the effects of oxidized quantum dots in epoxy nanocomposites.

It is great to see this article coming out after many years, thanks to my co-authors! Abstract Purpose Fused deposition modeling enables multiscale structure control. However, most of this structural space is unexplored. Specifically, the impact of biomimetic porous structures on the mechanical behavior and reliability of common thermoplastics are unclear. In this work, porous […]

Abstract Graphene quantum dots (GQDs) were reported to fill the role of nanofillers that enhance composite properties. Detailed investigation of this nanofiller in composites is largely unexplored. To understand the fundamental mechanisms in play, this study uses molecular dynamics simulations to reveal the effects of GQDs on epoxy properties. Mechanical simulations were performed on three […]
