Materials Seminar: Multiscale and Multiphysics Integrated Computational Material Engineering for Additive Manufacturing
Abstract: The presentation will focus on an overview of modeling, simulation (M&S) and experimental activities related to the integrated computational material engineering efforts at US-NRL from the perspective of the multiple length scales and multiple fields involved in layered deposition processes as they relate to Navy applications. The efforts described are a part of US-NRL’s internally funded effort on the “Science of Layered Deposition Processes”, grand-challenge effort directed by the speaker. The multiscale issues associated with Additive Manufacturing (AM) will be discussed first in order to lay out the scientific motivation of our efforts. Then, a description of overall analytical, experimental and computational components of the framework under development will be presented. Various aspects and current progress on some of the elements of this framework will be presented. Emphasis will be given on the solution of the multifield partial differential equations (PDEs) governing the spatio-temporal behavior of AM processes by using various discretization and model order reduction methods. A description of NRL’s AM Multiphysics Discrete Element Method, will also be presented with emphasis on its ability to predict porosity and surface roughness in addition to final part shape for powder-based AM processes. A methodology is introduce to enriched analytical solutions with functionality relevant to the practicalities of AM processes will be introduced and their accuracy and efficiency will be discussed from the perspective of enabling closed loop feedback control in real time. Progress on implicit slicing and multiscale topology optimization for functional tailoring of parts will also be presented. Multiphase field methods for predicting the evolution of the polycrystalline microstructure of multi-element alloys will also be outlined. Connection of process parameters to performance requires utilizing crystal plasticity for generating data-driven constitutive models enabling stress-strain response prediction, examples of which will also be outlined. Finally, AM part qualification methodologies introduced by our group will be presented via the use of automated multi-degree of freedom testing procedures.

Atlanta Science Festival: Science of Superpowers
Overview: Atlanta's mightiest heroes have come together as a team for this special ASF event. That's right - we're bringing together superhero scientists and engineers to tell us more about what parts of superhero science are actual science and what is still science fiction. Ever wonder if you'll have A.I. that can transition to physical form? What are the chances that aliens will look human? Will soldiers have computerized weapons systems in an armored exoskeleton suit? Moderated by Dr. Lisa Yaszek, Professor of Science Fiction Studies at Georgia Tech, our panel will feature experts in artificial intelligence, astrobiology, and nanotechnology. Come join the conversation! The panel discussion will take place in the theater, with family friendly activities in the lobby.

Nano@Tech: Organic Semiconductors in the Fourth Industrial Revolution
Abstract: In this talk, we will discuss how printable organic conjugated semiconducting molecules and polymers are creating new disruptive technologies that are impacting all industries. We will present recent advances in various solid-state device platforms including, organic light-emitting diodes (OLEDs), organic photodetectors (OPDs), organic photovoltaic devices (OPVs), and organic thin-film transistors (OTFTs). We will emphasize the importance of interfaces in devices and show examples on how to engineer their electrical properties. We will present a simple processing technique for the electrical doping of organic semiconductors over a limited depth near the surface of the film that is based on immersing the film into a polyoxometalate solution. Such approached can drastically reduce the fabrication cost of such devices, simplify device architecture, and lead to all-organic devices fabricated by all-additive printing techniques. As an illustration of the simplicity and versatility of this process we will discuss how high-performance organic solar cells with simplified architecture can be implemented. Finally, we will present the results of a detailed operational lifetime study of OTFTs showing that organic photonics and electronics can yield a stability level superior to that of amorphous silicon.
