Towards Molecular Modification Of Carbon Nanotube Junctions In Thin Film Transistors, Noelia Caloca, A. Nicole Chang, Kari Mclaughlin, David Estrada

College of Engineering Presentations

Carbon nanotube thin film transistors have recently been used on flexible and transparent substrates for applications in integrated circuits and display drivers. Such networks are of interest due to their relatively high carrier mobility and mechanical flexibility. However, the I_ON/I_OFF ratio of these networks varies inversely with the carrier mobility, and advances in reducing the electrical and thermal resistance of nanotube junctions are needed to improve the device performance and reliability. The objective of this work is create a process to improve CNT TFT device performance by using 0-dimensional molecules to modify the physical properties of the …

Resurrecting “Poor Man’S Purple”: A Transdisciplinary Study Of Color-Shifted Pigments Used In An Encaustic Fayum Mummy Portrait Of Ancient Egypt, Brittany Archuleta, Alaggio B. Laurino, Cameron E.

During the Coptic period in Fayum Egypt, encaustic (i.e. wax) mummy portraits were painted onto wooden panels or linen and attached to the mummy trappings of the deceased. One such portrait, “32.6: The Bearded Man” (c. 170-180 AD), features an unidentified Roman-Egyptian displaying a purple clavi. The trace swath of purple in the portrait provides evidence as to the origins of the painting and the identity of the man. Nanoscale analysis of the pigment suggests a red organic material was color shifted using a metal salt to produce a “poor man’s purple” as opposed to the expensive murex purple traditionally …

A Guideline For Increasing Efficiency Of Tem/Eds Data Collection By Dwell Time Optimization, Colin Green, Adam Thompson

College of Engineering Presentations

Composition analysis using energy dispersive spectroscopy (EDS) mapping in transmission electron microscopy (TEM) is crucial in the semiconductor industry for development of new products and enhancement of production yields. High quality EDS data relies on acquiring sufficient X-ray counts from the TEM sample. The amount of time that the electron beam interacts with the sample generating X-rays per pixel within the mapping area is known as dwell time, which is an EDS system parameter that governs optimum data acquisition. However, a systematic study to optimize this parameter has not been previously reported. An analytical expression was derived that enabled the …

A Transdisciplinary Approach To Determining The Provenience Of A Distorted, Pre-Columbian Skull Recovered In Rural Idaho, Jennifer K. Watkins, Gordon A. Alanko, Samantha H. Blatt, Cynthia A. Bradbury, Matthew J. Kohn, Marion Lytle, Deborah Lacroix, Joanna Taylor, John Dudgeon, Rebecca E. Hazard, Erin O’Leary-Jepsen, Darryl P. Butt

Transdisciplinary research involves cooperation, exchange of information, sharing of resources and integration of disciplines to achieve a common scientific goal. In this study, collaborators utilized tools and knowledge of materials science, anthropology, archaeology, geosciences and biology in an attempt to determine the provenience of skeletal remains of unknown origin. The exchange of ideas and skills along with the crossing of disciplines in this study sucessfully allowed the incorporation of expertise from many team members. This transdisciplinary approach to research provided a more comprehensive and detailed analysis than any one field alone could provide. An archaeological assessment of a human skull …

Zero-G Operable Interplanetary Delivery Based Ergonomics Grabber (Zoidberg), Davlin Jacob, Camille Eddy, John Cashin, Eli Andersen, Scott Warren, Zachary Chastaine, Colton Colbert, Christopher Ruby, Marina Autina

College of Engineering Presentations

The collection and storage of float samples without cross contamination is one of many challenges facing the National Aeronautics and Space Administration (NASA). The proposed tool will be able to retrieve rock samples with a series of sample collection clamshells attached to a rotating belt positioned on a shaft. There will be one clamshell per sample collection sight. The tool will meet all safety requirements and be able to retrieve the samples without compromising the integrity of the surrounding area. After thorough design review, a prototype will be tested at the Neutral Buoyance Lab (NBL) at NASA’s Johnson Spaceflight Center …

Augmented Reality And Gesture-Based Control, Camille Eddy, Josh Johnston

College of Engineering Presentations

This research investigates methods for interacting with 3D visualizations of science data. Even with higher resolution, large format, and stereoscopic displays, most visualization still involves the user looking at the result rendered on a flat panel. Changing perspective, zooming, and interpreting depth is often disorienting and frustrating. Specialized hardware and software solutions like large format displays and CAVEs address these issues with infrastructure limited by cost, complexity, and size.

We investigate low cost commercial hardware solutions for their potential application to this problem. The Leap Motion Controller and Kinect Motion Sensor are assessed for gesture-based visualization control. The Oculus Rift …

Science-Driven Immersive Environments For Land Management Simulations, Tim Wilder, Josh Johnston

College of Engineering Presentations

Our research explores automated techniques for visualizing environmental processes and land management decisions. The resulting 3D environment models provide a more realistic look and feel for simulated outcomes than 2D or 2.5D GIS maps and extracted statistics. Automated model generation reduces workflow complexity and increases fidelity by directly coupling science inputs with 3D output.

Urban and environmental scenes are generated within CityEngine utilizing GIS data from various sources. Procedural modeling is applied to create realistic 3D views of alternative scenarios predicted by the Envision integrated planning and environment assessment tool, as well as to visualize discrete events such as fire …
