A novel macroscopic Technique to measure the Nanomechanics of durable multifunctional Nanoshells

In the recent advancement of nanotechnology, carbon nanotubes (CNTs) have shown promise and potential due to their excellent mechanical, electrical, and optical properties for a wide variety of applications. A network of single-wall carbon nanotubes (SWCNTs) is of particular interest due to its applications in flexible electronics, composites, constructional materials, and so on. Understanding the mechanical properties of these nanoscale thin films is critical in order to fully characterize their behavior, whereas only a few methods are in the literature to determine the deformation mechanics of these films. In order to put some insight into the large-deformation mechanics, and relative lack of proper measurement techniques of such films, we propose a novel, simple, direct method for evaluating the mechanical characteristics of the SWCNT thin films. We provide the theoretical background, experimental approach, and a MATLAB based analysis to extract the data. Finally, we compare our result to existing wrinkling-based measurements, which shows reasonable agreement between the two techniques.


DNA Topology and Genomic Information Processing

Professor Laura Finzi

Department of Physics,
Emory University

 

Tuesday April 25, 3:00-4:00pm, Refreshments at 2:30.

271 Batcheller Technology Center <NOTE THE DIFFERENT ROOM>

DNA is a right-handed, double helical polymer that encodes genetic information. Its topology is dynamically changed by proteins and enzymes. In this talk, I will describe our use of single molecule techniques to understand critical topological changes that regulate genomic function.

Mining Deep Underground for Neutrinos: DUNE

David DeMuth

Department of Physics,
Valley City State University

 

Monday May 1, 3:00-4:00pm, Refreshments at 2:30.

221 South Engineering

High Energy Particle Physics research has deepened our understanding of the universe through world class explorations of energy and matter at a fundamental scale, prompting amazing discoveries, innovation, and technologies. A new particle physics experiment at Chicago’s Fermi National Accelerator Laboratory will focus neutrinos to a deep underground laboratory 800 miles away in South Dakota, near Sturgis, at a depth of 4,850 feet. The design, construction, and operation of precision particle detectors is coordinated by a large international collaboration of scientists and engineers who hope to answer big questions related to the origin of matter, unification of forces, supernova mechanics, and black hole formation.

In this presentation, Valley City State University Professor David DeMuth, Jr. will set a context for high energy particle exploration, discuss motivations for building a Deep Underground Neutrino Experiment,  highlight engineering design and challenges, indicate timeline, and suggest implications for Dakota’s student’s participation in neutrino research.  For more on DUNE: www.dunescience.org
