Atomistic and molecular simulations have become an important research field due to the progress made in computer performance and the necessity of new and improved materials. Despite this, first principle simulations of large molecules are still not possible because the high computational time and resources required. Other methods, such as molecular dynamics, allow the simplification of calculations by defining energy terms to describe multiple atom interactions without compromising accuracy...

Current nuclear reactor components consist of forged or casted Iron-based or Nickel-based alloys. Both these fabrication techniques present challenges in long-term performance and structural integrity. A possible alternative investigated in this research includes Powder Metallurgy (PM) combined with Hot Isostatic Pressing (HIP). Contributions to the research consisted of polishing, etching, and measuring the hardness and grain structures of the samples investigated.
Powder Compaction is a manufacturing technology which is used to mold granular particles to solid materials. Powder compaction is widely used by pharmaceutical companies to manufacture tablets with desired properties. It is imperative to understand the mechanics underneath the constituent granular particles that eventually contribute to properties of the manufactured tablets because properties of the final products are results of the microstructures that evolve during compaction...
We present the Optimized Workflow for Electronic and Thermoelectric Properties (OWETP) python notebook, which uses Density Functional Theory (DFT) as implemented in the Quantum Espresso code for electronic properties of materials. The OWETP python notebook also enables connecting to the Materials Project database, and the nanoHUB tool Landauer Transport Properties (LanTraP) for thermoelectric calculations.
Phase transforming cellular materials (PXCMs) are a new class of materials that can go through large deformation and return to their original configuration. Currently, there are reliable cellular materials that can resist large deformation, for example, honey comb; however, when these materials are compared to PXCMs, they cannot stay in their elastic range. The biggest advantage about PXCMs is that they are not only inexpensive materials, but they are also highly-durable and they absorb and...
