October 1 Advancements in Modeling, Sensing and Control for High-Resolution Additive Manufacturing | ABSTRACT


Additive manufacturing (AM) describes a class of processes that perform a layer-by-layer "bottom-up" fabrication approach as opposed to traditional top-down, subtractive fabrication such as milling and lathing. Printing-based AM, and in particular micro-scale AM (µ-AM), has received significant attention in recent years as an enabling technology capable of revolutionizing the way we manufacture electronics, biosensors, and optics in this country. Meso-scale AM is capable of fabricating integrated features beyond what conventional machining can perform at this length scale. However, µ-AM has yet to demonstrate the fabrication of complex 3D structures at the micro-scale that are not fabricable by traditional micromachining. Limiting this step change in manufacturing capabilities is the reliance of μ-AM systems on a process monitoring, regulation, and quality control paradigm that is performed post-process and in an ad hoc manner. In this talk, we discuss some recent developments in process modeling, sensing, and control that aim to break this open-loop paradigm by providing the controls theoretic and process modeling knowledge to develop a robust closed-loop system for measurement and compensatory control.

October 8 Biopolymer Systems for Tissue Regeneration and Therapeutics | ABSTRACT


Biomaterials are being heavily investigated for use as tissue scaffolds and bioactive factor delivery systems with applications in both tissue regeneration and cancer therapeutics. It is critical to develop controlled, localized delivery methods for therapeutics, as this will improve patient response, minimize side effects, and reduce treatment cost. The field of tissue engineering seeks to regenerate diseased or damaged tissues by providing the necessary physical, biochemical, and cellular cues that promote tissue regeneration.

In the body, cells are influenced by a large host of factors, including the presence of soluble signals such as growth factors, insoluble signals that are components of the extracellular matrix surrounding the cells, and also the interaction of various populations of cells with each other. Therefore, tissue engineering and therapeutic strategies must include some combination of soluble factors, insoluble factors, and cells to encourage the cells and their microenvironment to return to the natural, healthy state.

Our group seeks to develop biopolymer systems that allow the study of cells’ interactions with their microenvironment and that can be used for both tissue regeneration and therapeutics. We also develop controlled release systems that provide bioactive factors to the surrounding area of interest in a controlled, sustained manner over time.

October 29 Advances in Acquisition and Analysis of Hyperspectral Images: From Anthrax to Atoms | ABSTRACT


In less than 20 years the microanalysis community has seen incredible changes in computing power and technology for acquisition and analysis of X-ray spectral data with the advent of hyperspectral imaging (where complete x-ray spectra area acquired from a 2D array of points) and advanced statistical data analysis methods. Advances in X-ray detector technology have made possible the development of multi-sensor configurations which have more recently been fitted to scanning transmission electron microscopes. This has allowed even atomic-resolution X-ray data to be acquired and quantified. This presentation will reflect upon historical developments in computers and analytical instrumentation and how my career fits in with these in particular with respect to data analysis methods. There will be numerous applications discussed covering our work with the FBI on their investigation of the 2001 Anthrax attacks through atomic-resolution elemental analysis and many points in between.


Paul Kotula, Sandia National Laboratories | BIO


Paul Kotula is a staff member at Sandia National Laboratories in Albuquerque, NM. He received his B.S. from Cornell University and his Ph.D. from the University of Minnesota, both in Materials Science and Engineering. Before joining Sandia he was a Post-Doctoral Fellow at Los Alamos National Laboratory. Paul has authored or co-authored over 100 journal articles on a wide variety of topics involving electron microscopy and microanalysis in the physical and biological sciences, as well as three patents and three book chapters. Paul has helped build a research program on spectral imaging and multivariate statistical analysis. This technology development was central to his involvement in the FBI’s investigation of the 2001 anthrax attacks. The software developed from this work for X-ray microanalysis is commercially and non-commercially available and is now in over 600-labs worldwide. Paul has received an R&D 100 Award, two Best Analytical Techniques paper awards in the journal Microscopy and Microanalysis and the Heinrich Award for Outstanding Young Scientist from the Microanalysis Society. He is a Past-President of the Microanalysis Society and is currently a Physical Sciences Director of the Microscopy Society of America.
