Sensors For The Detection Of Ammonia As A Potential Biomarker For Health Screening, Peter P. Ricci, Otto J. Gregory

Chemical Engineering Faculty Publications

The presence of ammonia within the body has long been linked to complications stemming from the liver, kidneys, and stomach. These complications can be the result of serious conditions such as chronic kidney disease (CKD), peptic ulcers, and recently COVID-19. Limited liver and kidney function leads to increased blood urea nitrogen (BUN) within the body resulting in elevated levels of ammonia in the mouth, nose, and skin. Similarly, peptic ulcers, commonly from H. pylori, result in ammonia production from urea within the stomach. The presence of these biomarkers enables a potential screening protocol to be considered for frequent, non-invasive …

Free-Standing, Thin-Film Sensors For The Trace Detection Of Explosives, Peter P. Ricci, Otto J. Gregory

Chemical Engineering Faculty Publications

In a world focused on the development of cybersecurity, many densely populated areas and transportation hubs are still susceptible to terrorist attacks via improvised explosive devices (IEDs). These devices frequently employ a combination of peroxide based explosives as well as nitramines, nitrates, and nitroaromatics. Detection of these explosives can be challenging due to varying chemical composition and the extremely low vapor pressures exhibited by some explosive compounds. No electronic trace detection system currently exists that is capable of continuously monitoring both peroxide based explosives and certain nitrogen based explosives, or their precursors, in the vapor phase. Recently, we developed a …

Computational Study Of Helical And Helix-Hinge-Helix Conformations Of An Anti-Microbial Peptide In Solution By Molecular Dynamics And Vibrational Analysis, Faramarz Joodaki, Lenore M. Martin, Michael L. Greenfield

Chemical Engineering Faculty Publications

Many classical antimicrobial peptides adopt an amphipathic helical structure at a water-membrane interface. Prior studies led to the hypothesis that a hinge near the middle of a helical peptide plays an important role in facilitating peptide-membrane interactions.Here, dynamics and vibrations of a designed hybrid antimicrobial peptide LM7-2 in solution were simulated to investigate its hinge formation.Molecular dynamics simulation results on the basis of the CHARMM36 force field showed that the $\alpha$-helix LM7-2 bent around two or three residues near the middle of the peptide, stayed in a helix-hinge-helix conformation for a short period of time, and then returned to a …

In Situ Sers Detection Of Dissolved Nitrate On Hydrated Gold Substrates, Timo Küster, Geoffrey D. Bothun

Chemical Engineering Faculty Publications

The accurate and fast measurement of nitrate in seawater is important for monitoring and controlling water quality to prevent ecologic and economic disasters. In this work we show that the in situ detection of nitrate in aqueous solution is feasible at nanomolar concentrations through surface enhanced Raman spectroscopy (SERS) using native nanostructured gold substrates without surface functionalization. Spectra were analyzed as collected or after standard normal variate (SNV) normalization, which was shown through Principal Component Analysis (PCA) to reduce spectral variations between sample sets and improve Langmuir adsorption model fits. An additional normalization approach based on the substrate silicon template …

Integrating The Humanities With Engineering Through A Global Case Study Course, Kirsten A. Davis, Siddhant S. Joshi, Lori Czerwionka, Francisco Montalvo, Gabriel O. Rios-Rojas, Joe Tort, Jennifer Marston William, E. Nauman

Journal of International Engineering Education

As the world becomes more connected and globalized, the problems that engineers are called upon to solve are increasingly complex and interdependent. Unfortunately, engineering coursework has traditionally focused on abstract and closed-ended problem solving, offering few opportunities for students to develop these skills. In this practice paper, we argue for the importance of integrating the humanities and engineering to understand the multiple and intersecting layers of context in an engineering project. We then describe the Humanities-Informed Engineering Projects course, which we developed to help students acquire this perspective. The course was piloted in Spring 2021 in response to the obstacles …

We have developed carbon nanotube–liposome complexes (CLCs) and incorporated these structures into a 3D alginate hydrogel for use as an optically controlled drug delivery system. The CLC structures were characterized by using a variety of imaging and spectroscopic techniques, and an optimal SWCNT/lipid ratio was selected. …

Technology Criticism And Data Literacy: The Case For An Augmented Understanding Of Media Literacy, Thomas Knaus

Journal of Media Literacy Education

Reviewing the history of media literacy education might help us to identify how creating media as an approach can contribute to fostering knowledge, understanding technical issues, and to establishing a critical attitude towards technology and data. In a society where digital devices and services are omnipresent and decisions are increasingly based on data, critical analysis must penetrate beyond the “outer shell” of machines – their interfaces – through the technology itself, and the data, and algorithms, which make these devices and services function. Because technology and data constitute the basis of all communication and collaboration, media literate individuals …

Fixing Social Media: Toward A Democratic Digital Commons, Michael Kwet

Markets, Globalization & Development Review

In the past few years, big Social Media networks like Facebook, Twitter, and YouTube have received intense scrutiny from the intellectual classes. This article critiques the dominant strain of criticism, the neo-Brandeisian School of antitrust, for its narrow focus on “regulated competition” as an appropriate means to “fix social media”. This essay calls for a socialist alternative: a democratic social media commons based on free and open source technology, decentralization, and democratic socialist legal solutions. It reviews how existing solutions like the Fediverse and LibreSocial work, and how they may provide answers for a better way forward.
