Magnetic Properties Of Polycrystalline Spinel Oxides From Solid State Reaction, Camden Olds May 2023

Magnetic Properties Of Polycrystalline Spinel Oxides From Solid State Reaction, Camden Olds

Honors Theses

Spinel crystal materials of nickel, cobalt, and iron oxides have seen abundant research for their strong conductivity, ferromagnetic and ferroelectric properties, and their catalytic uses. These can be synthesized by a number of means. This project explores the use of the solid state synthesis method, which benefits from simplicity, of this family of materials, looking for interesting phase shift lines in the triangle between of varying compositions of these three metals.

Nickel cobaltite and other related spinels were synthesized from two different solid state approaches and characterized using XRD and SQUID magnetometry. The range 0.5-0.6 of molar ratios of nickel …

Stem Club, Camden Jones, Erica Gesner, Amber Gadeken

Honors Expanded Learning Clubs

The goal of this club is to introduce various topics stemming from different fields in science. We hope to excite the students about science and show them how important it is to their everyday lives. This club also aims to provide free education to underserved communities.


Identifying, Analyzing, And Using Discriminatory Variables For Classification Of Neutrino Signal And Background Noise In Multivariate Analysis In The Askaryan Radio Array Experiment, Jesse Osborn Mar 2021

Identifying, Analyzing, And Using Discriminatory Variables For Classification Of Neutrino Signal And Background Noise In Multivariate Analysis In The Askaryan Radio Array Experiment, Jesse Osborn

Honors Theses

The Askaryan Radio Array Experiment, located near the South Pole, works to pinpoint specific instances of neutrinos from outside the solar system interacting with nucleons inside the Antarctic ice, emitting radio waves. I have taken data from the ARA stations which is presumed to be background noise and compared it to simulated data meant to look like a neutrino signal. I developed a suite of variables for discrimination between the two data sets, using a computer algorithm to generate a single output variable which can be used to distinguish noise events from signal events. I maximized this discrimination process for …


Electron Beam Dispersion Compensator Using A Wien Filter, Jackson Lederer Mar 2021

Electron Beam Dispersion Compensator Using A Wien Filter, Jackson Lederer

Honors Theses

When an electron beam travels through space, it spreads out over time which impedes the ability to work with short electron pulses in the lab. A Wien filter is a device consisting of perpendicular electric and magnetic fields which filters charged particles based on their velocities. For a specific velocity, the two forces from the two fields in the filter cancel each other out letting charges with that velocity travel straight through the filter. Charges moving at other speeds are deflected as they have a net force applied to them from the filter. If a particle is deflected from the …


Got Science? Club, Nora Husein, Randa Ismail Apr 2020

Got Science? Club, Nora Husein, Randa Ismail

Honors Expanded Learning Clubs

Got Science? Club allows students to learn about the science that can be found in our daily lives using everyday items such as food and school supplies. Students will learn about these sciences through hands-on experiments, allowing them to truly experience the science around them.


Application Of Bradford’S Law Of Scattering On Research Publication In Astronomy & Astrophysics Of India, Satish Kumar, Senthilkumar R. Dec 2018

Application Of Bradford’S Law Of Scattering On Research Publication In Astronomy & Astrophysics Of India, Satish Kumar, Senthilkumar R.

Library Philosophy and Practice (e-journal)

The present study is focused on examining the application of Bradford’s law of scattering on research articles published in the field of Astronomy & Astrophysics by Indian scientist during 1988-2017. The bibliographic data was retrieved from Web of Science (WoS) bibliographic data base for different period of time. Total 18,877 journal’s article have been published by Indian scientist in the field of Astronomy & Astrophysics during 1988-2017 which was further retrieved and analyzed separately for different blocks of 10 years as well as for 30 years consolidated too. The core journal of the field was identified. The Bradford law of …


Makerspace Club, Carolyn Brady Oct 2018

Makerspace Club, Carolyn Brady

Honors Expanded Learning Clubs

This is a unique club that allows children to explore the world around them and make projects using materials provided by educators, and to get children thinking about how things work in the world, and how they do. They gain knowledge about success and failure of these things by recreating them.


Phys 231: Electric And Electronic Circuits—A Peer Review Of Teaching Project Benchmark Portfolio, Xiaoshan Xu Jan 2015

Phys 231: Electric And Electronic Circuits—A Peer Review Of Teaching Project Benchmark Portfolio, Xiaoshan Xu

UNL Faculty Course Portfolios

In this portfolio, I employed a backward design teaching approach on the course PHY231 (Electric and Electronic circuit). I first decide the course objectives and choose the teaching strategies and activities emphasizing student engagement and feedbacks. The effectiveness of the teaching strategies and activities are assessed throughout the course; the adjustments are made accordingly. The results are analyzed at the end of the semester. The assessments indicate that the course objectives are fundamentally achieved and the teaching strategies are effective.

The objectives of the course are:

  1. Students will reinforce their understanding in electricity and magnetism.
  2. Students will learn theory of …


Science On The Great Plains: The History Of Physics And Astronomy At The University Of Nebraska-Lincoln, M. Eugene Rudd Jan 1992

Science On The Great Plains: The History Of Physics And Astronomy At The University Of Nebraska-Lincoln, M. Eugene Rudd

M. Eugene Rudd Publications

The year 1988 marked the 100th anniversary of the founding of the Department of Physics at the University of Nebraska. While the year passed without fanfare in the department, DuaneJaecks, one of the members of the faculty, suggested to the author that it would be a good time to write a history of what is now the Department of Physics and Astronomy. He not only provided the initial impetus for the project, but has also given it his continual help and encouragement. While the initial plan was to write only a brief, informal departmental history, the project, like Topsy, grew. …
