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...

This presentation demonstrates how the classical diffusion-capture (D-C) model has improved sensor performance, since the D-C model is a \“geometry of diffusion\” rather than a \“geometry of electrostatics.\” A scaling law based on D-C is also posited; the scaling law resolves many classical puzzles and aids the interpretation of experiments to date with a simple coherent framework.

The ability to read the book of life, written in the genome of an organism, has been one of the most exciting development of our time. The first version of human genome was announced circa 2000 and it took a decade of industrial-scale collaboration and billions of dollars of funding. Today, we do the same for a few hundred dollars, and in a few hours time. In merely 10 years, the reactors that covered a football field has been reduced to the size of a postage-stamp. I will explain how a synthesis of electronics and biotechnology, especially the use of electronic biosensor made of i-phone scale transistors, has made this fantastic development possible.

In this talk, I will discuss an elementary theory of the role of nanostructured electrodes in addressing some of the challenges from a fundamentally different perspective. The goal is to start a conversation regarding the viability of the approaches suggested and see if the perspective offered is realistic and relevant.

This talk presents some examples of state-of-the-art integrated imaging systems based on computed tomography (CT), transmission electron microscopy (STEM), synchrotron beam imaging, optical sensing, and scanning electron microscopy (SEM). For each of these examples, we also explore their use and potential impact in applications ranging from healthcare to jet engine design. We conclude with some speculation on where integrated imaging might be going; where it might have greatest impact; and what will be the greatest challenges ahead.
