Effect Of Structural Disorder On Magnetic Properties Of Mncrval, Juliana Herran, Rishabh Dalal, Paul Gray, Pavel Lukashev

Research in the Capitol

Operation of virtually any modern electronic device relies on magnetic materials. In particular, these materials are the cornerstone of data storage and processing in computer hardware elements, such as hard drives and random access memories. Here, we theoretically study an interplay between structural and magnetic properties of MnCrVAl, a material which recently attracted significant attention due to its rather exotic electronic structure. In particular, this material behaves either as an insulator or as a metal, depending on which “spin” (an intrinsic property of any fundamental particle) of the electron is considered. Using advanced computer simulation techniques (density functional calculations on …

Tio2 Coating Method For Nanocellulose Aerogel, Byron Fritch, Tim Kidd

Research in the Capitol

Titanium dioxide has been shown to be an effective catalyst for splitting water into hydrogen and oxygen gas. By increasing the surface area of the titanium dioxide catalyst, the rate of water splitting may increase. A possible method to increase the splitting of water uses a high surface area composite material formed by coating nanocellulose aerogels with titanium dioxide. Different coating methods were studied using titanium isopropoxide as the titanium dioxide source to create such composites. It was found that the most consistent titanium dioxide coatings were formed during a 12 hour titanium isopropoxide vapor bath. Other coating methods collapsed …

Stable Isotope Chemistry In Titan Haze Aerosol, Allison Wold, Thomas Gautier, Jennifer Stern, Joshua Sebree, Melissa Trainer

Research in the Capitol

Titan, a moon of Saturn, has a thick atmosphere made up of nitrogen and a few percent methane, with a surface pressure of 1.5x that of Earth. Titan’s atmosphere is believed to be that similar to that of early Earth before the rise of O2. One significant source of information on the history and evolution of the atmosphere is the measurement of stable isotopes of elements in the molecules of major gases such as nitrogen, methane, and higher order hydrocarbons. The fractionation associated with the formation of Titan aerosol analogs are explored in the laboratory as a function of environmental …

Weathering In Iowa: Not What You May Think, Alexa Sedlacek

UNIversitas: Journal of Research, Scholarship, and Creative Activity

When I look at the limestone bedrock of Iowa, as I did just the other day with my daughter (figure 2—[credit: Aaron Spurr, Quarry October 2, 2016]), I see long-term carbon storage. I do not mean a place to sequester modern atmospheric CO2 into the subsurface. Rather, limestones in Iowa and around the world represent carbon that was removed from the atmosphere through geologic processes and stored in these carbonate rocks. Carbon storage in rocks such as limestone and fossil fuels are responsible for the large scale changes in atmospheric CO2 concentrations throughout Earth’s history.

An autumn afternoon about ten years ago, I found myself lying on the ground in the shade of a hundred-year-old live oak tree in Myakka River State Park in southwest Florida. The broad limbs of the ancient tree at once rose up like arms honoring the heavens and bowed down to the ground in an elegant semblance of thanksgiving.

The Role Of Working Memory Among Non-Traditional Foreign Language Students, Gabriela Olivares-Cuhat, Michelle H. Ploof

UNIversitas: Journal of Research, Scholarship, and Creative Activity

Over the last 40 years, a growing number of nontraditional students have joined the ranks of higher education. However, due to a number of internal and external factors, these students face multiple social, economic, and academic challenges that may limit their success in postsecondary education. The focus of this article is to examine the implications of these challenges on the learning of a foreign language (FL), and more specifically on the role played by working memory (WM) with nontraditional FL learners. To this end, research studies in the fields of psycholinguistics, cognitive psychology and neuroscience are reviewed and their findings …

Introduction: Building Bridges And Weaving Webs, Elizabeth Sutton

UNIversitas: Journal of Research, Scholarship, and Creative Activity

The impetus for this forum was the UNI Creating a Responsible Environment Showcase (UNI CARES) event held in April, 2016. The goal of the showcase was to bring together the various domains (or disciplines, as it were) of researchers, teachers, students, and staff who contribute to active learning, expanded thinking, and environmental renewal at UNI. Correspondingly, the Provost’s Common Read brought diverse groups of students, faculty, and staff together to discuss the broader implications of Andrea Wulf’s biography of Alexander von Humboldt (1769-1859), The Invention of Nature. I want to take some of the themes raised in these events …

2016/17 Dry Run Creek Geomorphological Watershed Assessment, University Of Northern Iowa. Department Of Earth And Environmental Sciences.

UNI Conservation Corps Projects

Dry Run Creek (DRC) watershed is a primary drainage basin located in northwestern Black Hawk County (Figure 1). It is fed predominantly by agricultural runoff in its upper reaches, and becomes heavily urbanized as it travels through the city of Cedar Falls, before draining into the Cedar River. The stream is perennial, however some are tiled and new segments have developed both naturally and artificially. Re-evaluation of the creek is underway and indicates some changes in urban and rural areas. Data was collected between Fall 2016 & Fall 2017 by University of Northern Iowa geomorphology students, using handheld GPS devices …

Community Rain Gardens: Rainscaping Group Project Report, University Of Northern Iowa. Center For Energy & Environmental Education.

UNI Conservation Corps Projects

A rain garden is a depression created in a landscape that allows water runoff from rooftops, driveways, and/or streets to pool or be ponded. The water does not stay, it only captures this runoff and allows it to infiltrate into the ground recharging groundwater instead of running off into our sewer systems and in turn into our rivers and streams. Rain gardens are an infiltration-based storm water treatment management system. The idea here is to add beauty in the landscaping of these rain gardens while also treating home's rooftop and driveway runoff, which allows them to be both aesthetically pleasing …

Herbaceous Vascular Flora Of Forested Seep Wetlands In Winneshiek County, Iowa, Usa, Elizabeth A. Lynch, Anna Burke Weckwerth

Journal of the Iowa Academy of Science: JIAS

Forested seep wetlands dominated by skunk cabbage (Symplocarpus foetidus) occur frequently in the Canoe Creek watershed of the Upper Iowa River, but this type of wetland has not been described systematically in the upper Midwest. The goal of this study is to document the herbaceous plant flora of five seeps. Although individual seeps are small (200-500 m²), they provide habitat for a high number of plant species. Five seeps with total area less than 0.2 ha supported more than 120 native vascular herbaceous taxa, 20 of which have a coefficient of conservatism (C-value) of 7 or …
