Click Reactions With Surface-Bound Phosphonate Films Toward An Electrocatalytic System For Carbon Dioxide Reduction, Iaroslavna Kovalenko, Emma J. Goehner, K. Nicole Crowder Apr 2026

Click Reactions With Surface-Bound Phosphonate Films Toward An Electrocatalytic System For Carbon Dioxide Reduction, Iaroslavna Kovalenko, Emma J. Goehner, K. Nicole Crowder

Research and Creativity Symposium

One way to electrochemically reduce CO2 is to use modified electrode surfaces with bound transition-metal electrocatalysts. Optimal conditions for modifying copper surfaces with a 1.0 mM solution of (2-azidoethyl) phosphonic acid in acetone have been identified, forming a self-assembled monolayer (SAM) via the tethering by aggregation and growth (T-BAG) method. The SAM protects the copper electrodes from oxidation or side reactions on the copper surface. The copper-catalyzed azide-alkyne cycloaddition (CuAAC) click reaction between the terminal azide group on the phosphonate and the terpyridine ligand has been successfully carried out on the copper surface. This terpyridyl ligand was then used …


The Atmospheric Effects On The Extratropical Transition Of Hurricane Sandy, Natalie Paone Apr 2026

The Atmospheric Effects On The Extratropical Transition Of Hurricane Sandy, Natalie Paone

Ocean Engineering and Marine Sciences Student Publications

  • Hurricane Sandy formed in the Caribbean in late October 2012 and intensified to a Category 3 hurricane before making landfall in Cuba and later New Jersey (Blake et al., 2013). Sandy caused approximately $68.7 billion in damages and over 250 fatalities, making it one of the most impactful storms in U.S. history. 
  • During extratropical transition (ET), tropical cyclones interact with midlatitude systems, leading to structural changes such as expansion of the wind field, development of frontal boundaries, and increased baroclinicity (Hart and Evans, 2001). Sandy is a key example of a hybrid cyclone where ET did not weaken impacts but …


Tiny Engineers: How Polycheateworms Can Extend Sedimentary Oxic Layers And Create Better Seagrass Habitats, Natalie Spohn Apr 2026

Tiny Engineers: How Polycheateworms Can Extend Sedimentary Oxic Layers And Create Better Seagrass Habitats, Natalie Spohn

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is a shallow, well mixed estuary on the East Coast of Florida. Presently, the IRL is suffering eutrophication due to a cycle of harmful algal blooms (HABs) that deplete the water column of oxygen (2,5). Deposition of organic matter from HABs in the sediment leads to reduced sedimentary oxygen, continuing to support the cycle of eutrophication through benthic-pelagic coupling (1,5). Anaerobic sedimentary conditions can increase concentrations of ammonium and sulfide, leading to seagrass loss (3,4,6,7,10). Bioturbation by infauna can extend the oxic layer of sediments, promoting aerobic processes and helping to remove nitrogen and sulfur …

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is one of the most biologically diverse estuaries in the United States and contributes over $55.4 billion annually to Florida’s economy. Since 2010, more than 52% of the IRL seagrass meadows have been lost, reducing both the ecological and the economic potential of this ecosystem. Biochar, a stable carbon material produced by pyrolysis, added to soil enhance organic productivity perhaps because of increased microbial activity in the soil (Lehmann et al., 2017). Our study evaluates the use of biochar to grow resilient strains of seagrass for ecosystem restoration in the IRL.

Thermoelectric Migraine Cooling Cap, Emily Ralston Apr 2026

Thermoelectric Migraine Cooling Cap, Emily Ralston

Ocean Engineering and Marine Sciences Student Publications

Migraines affect millions of people and can cause serious pain and discomfort. Many people use ice packs or cooling wraps to try to reduce the pain, but these only stay cold for a short amount of time. Because of this, there is a need for a cooling system that can provide longer and more controlled cooling. This project focuses on designing and building a wearable cooling cap that uses thermoelectric cooling technology. The goal is to create a system that can cool the head while moving heat away toward the neck area and help reduce migraine discomfort.


Recycling Spent Brewing Yeast As A Shrimp Feed Supplement, John Denvir Apr 2026

Recycling Spent Brewing Yeast As A Shrimp Feed Supplement, John Denvir

Ocean Engineering and Marine Sciences Student Publications

The aquaculture industry relies heavily on commercial fish feed, which accounts for over 50% of production costs and limits farm profitability worldwide[1]. Breweries generate about 3 gallons of high-strength wastewater per gallon of beer produced, much of it discarded as an oxygen-depleting pollutant from spent yeast[2]. Therefore, this project tests recycling spent brewer's yeast into a sustainable fish feed supplement to cut aquaculture costs and divert brewery waste from waterways, promoting circular food systems.

Gamma Ray Burst Afterglow Slopes, Brian Robbins Apr 2026

Gamma Ray Burst Afterglow Slopes, Brian Robbins

Aerospace, Physics, and Space Science Student Publications

The standard models for gamma ray bursts (GRBs) typically assume that shockaccelerated electrons follow a power law distribution of energies. However, this behavior is not what some gamma ray bursts show. In this project, it is suggested that the presence of thermal electrons causes temporal and spectral structure across the afterglow, which is significantly different from models assuming a pure power-law distribution of electrons. To model the afterglows, we decide on a large number of samples of GRBs from the Swift database and obtain the temporal and spectral indices at arbitrary times. By finding the temporal and spectral indices at …

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary Apr 2026

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary

Chemistry and Chemical Engineering Student Publications

Cyanines are highly conjugated molecules with useful properties, such as ease of aggregation and fluorescence. In this project, they were incorporated into an acrylamide-based nanogel made through organic synthesis to exploit these properties for controlled drug delivery. Exposing the nanogel to nearinfrared (NIR) light causes it to react with reactive oxygen species (ROS), forming an unstable intermediate. The intermediate splits into two fragments, releasing the nanogel's cargo.1 The cargo, temozolomide, is an alkylating agent which can be used to disrupt the DNA of cancer cells.


Electron Emission From Unactivated Gaas: Towards The Development Of Novel Sources Of Spin-Polarized Electrons, William Truslow Newman Apr 2026

Electron Emission From Unactivated Gaas: Towards The Development Of Novel Sources Of Spin-Polarized Electrons, William Truslow Newman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Spin-polarized electrons are commonly emitted from GaAs photocathodes with treated surfaces in a process called negative electron affinity activation. These sources require stringent vacuum conditions that are often hard to achieve and lead to significant downtimes in experiments. In this dissertation, I present new investigations of electron emission from unactivated GaAs towards the development of novel sources of spin-polarized electrons. The work entails two primary directions. The first is the investigation of electron emission using multiphoton ionization processes enhanced by nanoscale surface structures. We explore GaAs electron sources including, shards, nanotip arrays of pyramid structures, wedges, and ion-milled tips. The …


Worldview-Bench: A Benchmark For Evaluating Global Cultural Perspectives In Large Language Models, Abdullah Mushtaq, Imran Taj, Rafay Naeem, Ibrahim Ghaznavi, Junaid Qadir Apr 2026

Worldview-Bench: A Benchmark For Evaluating Global Cultural Perspectives In Large Language Models, Abdullah Mushtaq, Imran Taj, Rafay Naeem, Ibrahim Ghaznavi, Junaid Qadir

All Works

Background: Large Language Models (LLMs) are predominantly trained and aligned in ways that reinforce Westerncentric epistemologies and socio-cultural norms, leading to cultural homogenization and limiting their ability to reflect global civilizational plurality. Existing benchmarking frameworks fail to adequately capture this bias, as they rely on rigid, closed-form assessments that overlook the complexity of cultural inclusivity. Objectives: To address this cultural bias problem, we introduce WorldView-Bench, a benchmark designed to evaluate Global Cultural Inclusivity (GCI) in LLMs by analyzing their ability to accommodate diverse worldviews. Methods: Our approach is grounded in the Multiplex Worldview proposed by Senturk et al., which distinguishes …

Thiocoumarin As A Photocaging Scaffold: Synthesis And Light- Triggered Release, Angelina Gaffey, Gabrielle Depowski, Victor Johnson Apr 2026

Thiocoumarin As A Photocaging Scaffold: Synthesis And Light- Triggered Release, Angelina Gaffey, Gabrielle Depowski, Victor Johnson

Chemistry and Chemical Engineering Student Publications

Photocaging involves inhibiting a molecule’s function with a photolabile protecting group (PPG), allowing for precise spatiotemporal control and release of the molecule in vivo. Photocages which respond to UV light upon single photon irradiation have limited use in vivo due to cytotoxicity. Thiocoumarin is a promising photocage which absorbs in the visible light region and can cage multiple essential neurotransmitters, such as GABA and glutamate. In addition, thiocoumarin can be easily tracked through live cells due to its persistent fluorescence throughout the caging process. In this project, GABA was utilized to explore the properties of thiocoumarin as a light-triggered photocage.

Reconstructing Nebraska’S Late Quaternary Paleoenvironment, Landscape Change, And Human–Environment Dynamics Using Diatoms And Optically Stimulated Luminescence Dating, Gosia Mahoney Apr 2026

Reconstructing Nebraska’S Late Quaternary Paleoenvironment, Landscape Change, And Human–Environment Dynamics Using Diatoms And Optically Stimulated Luminescence Dating, Gosia Mahoney

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation examines Holocene environmental change and human–environment interactions in the Nebraska Sand Hills by integrating geomorphic, paleoenvironmental, and geochronological data. It presents three complementary studies that together explore how climatic variability, local landscape processes, and human activity influenced environmental systems.

The first study reconstructs the early Holocene evolution of a dune-dammed valley in the central Sand Hills. Stratigraphic, sedimentological, and diatom evidence indicate that eolian activity resulted in a blocked fluvial system, leading to elevated groundwater levels and the formation of a wetland that later developed into a lake. Notably, this transformation occurred under relatively dry conditions, demonstrating that …
