Information Literacy & Open Access For Physics And Astronomy Graduate Students, Jackie K. Werner Oct 2015

Information Literacy & Open Access For Physics And Astronomy Graduate Students, Jackie K. Werner

University Library Faculty Presentations

This presentation covers research on the physics and astronomy graduate students’ use and understanding of open access resources. The research, which was conducted in summer 2015, surveyed the physics and astronomy graduate students of Georgia Institute of Technology to discover how graduate students discover open access and other academic resources, as well as their level of awareness about open access in general and specific OA databases in particular. The research also included an interview with the graduate studies advisor in the Physics & Astronomy department Georgia Tech. The presentation also describes open access resources in Physics and Astronomy and relates the ...


Nasa Nebraska High Altitude Ballooning And The Fab Lab, Kendra Sibbernsen, Michael Sibbernsen Jun 2015

Nasa Nebraska High Altitude Ballooning And The Fab Lab, Kendra Sibbernsen, Michael Sibbernsen

2017 Academic High Altitude Conference

The NASA Nebraska High Altitude Ballooning (N-NHAB) program has collaborated on projects with the Fab Lab at Metropolitan Community College (MCC) in Omaha, NE. Based on the MIT Center for Bits and Atoms, the Fab Lab contains 3D printers, laser cutters, CNC machines, and much more. In its trial phase, the Fab Lab encouraged projects from the sciences. In response to this request, one of these projects involved a HAB student who wanted to streamline custom circuitry for measuring the efficiency of solar cells. The circuit pathways were designed and precisely cut from a copper sheet and the laser cutter ...


Microfluidic Generator Of Sub-10-Micron Hydrosomes, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor Apr 2015

Microfluidic Generator Of Sub-10-Micron Hydrosomes, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor

John Wesley Powell Student Research Conference

Known as the fundamental “lab on a chip” technology, microfluidics is a thriving young research area that first took off in the 1990s. It is commonly used for reducing the amount of material required for biochemical analysis, such DNA sequencing. Its narrow tunnels can annihilate turbulence even in high-speed fluid flow, facilitating controlled, systematic processing. Also, by leveraging lithographic techniques developed for the semiconductor industry, enormous capability can be integrated into a single microfluidic chip. We have thus far utilized templates designed and fabricated by previous students in our lab, for fabrication of a series of microfluidic chips, made of ...


Assembly, Alignment, And Maintenance Of An Automated Laser Cutter, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor Apr 2015

Assembly, Alignment, And Maintenance Of An Automated Laser Cutter, Zhenghao Ding, Lunjun Liu, Gabriel C. Spalding, Faculty Advisor

John Wesley Powell Student Research Conference

We have assembled a kit for an automated laser cutter system, intended to play an important role in a wide variety of student-led design projects on our campus. We began by electrically soldering the wiring for a powerful (60 Watt), pulsed infrared (10.6µm wavelength) CO2 laser beam, which can thermally induce shock waves that locally ablate a wide range of (non-reflective) materials. The laser tube itself generates significant heat when operating, so we also assembled the required water-cooling system. Given the high powers involved, careful alignment this invisible laser was required, to ensure that the beam is safely ...


A New Laboratory For Mm-/Sub-Mm-Wave Characterization Of Cosmic Dust Analogs, Lunjun Liu, Thushara Perera, Faculty Advisor Apr 2015

A New Laboratory For Mm-/Sub-Mm-Wave Characterization Of Cosmic Dust Analogs, Lunjun Liu, Thushara Perera, Faculty Advisor

John Wesley Powell Student Research Conference

At visible wavelengths, cosmic dust obscures many interesting astronomical environments such as stellar nurseries and new planetary systems. Studying how light interacts with cosmic dust would help reveal the nature of the objects and environments that are obscured by dust. In order to study the optical properties of cosmic dust analogs in the lab, we constructed a custom apparatus, which consists of a vacuum chamber, a cooling mechanism to vary the temperature of dusts in an astronomically interesting range (7-50 Kelvin), and a long-wavelength spectrometer. Since completing the construction of the custom apparatus, we are currently assembling and testing the ...


Size Matters, Morton Sternheim Jan 2015

Size Matters, Morton Sternheim

Nanotechnology Teacher Summer Institutes

Size matters in the way materials behave. An introductory PowerPoint and an activity write-up. Three activities illustrate how the surface to volume ratio changes as the size changes. In the first, a deck of playing cards is used to make square arrays of cards of increasing size. Next wooden cubes are used to make similar observations in 3 dimensions. Finally, comparing the rates at which an intact Alka Seltzer tablet and a crushed tablet react in water shows the effect of particle size on chemical reactions.


Nanoscale Thin Films, Rob Snyder Jan 2015

Nanoscale Thin Films, Rob Snyder

Nanotechnology Teacher Summer Institutes

An activity that makes a nanoscale film of oleic acid on water. The student will

  • Learn about Ben Franklin’s observations of a thin film that had a nanoscale dimension.

  • Create a very thin film with a very dilute solution of oleic acid.

  • Use data you collect to determine if you made a thin film with a nanoscale dimension that formed on the surface of water.

  • Learn about the molecular interactions that resulted in the formation of the thin film.

  • Be introduced to the Big Ideas of Nanoscale Self-Assembly


Powers Of Ten: From Meters To Nanometers And Beyond, Rob Snyder Jan 2015

Powers Of Ten: From Meters To Nanometers And Beyond, Rob Snyder

Nanotechnology Teacher Summer Institutes

The goal of this activity is to guide students toward an understanding of nanoscale dimensions by:

  • Making a number of measurements using meter sticks, magnifiers, microscopes and spectrometers so students can make observations and generate their own data.

  • Using scientific notation to compare the measurements they have made with the dimensions of very small structures
