‘Cassette’-ISES (In Situ Enzymatic Screening) Identifies Complementary Chiral Scaffolds for Hydrolytic Kinetic Resolution Across a Range of Epoxides

A new ‘Cassette’-In Situ Enzymatic Screen (ISES) for combinatorial catalysis is introduced. This allows the experimentalist to obtain an information-rich readout, in real time, providing an estimate of the sense and magnitude of enantioselectivity across more than one substrate. In its first iteration, the screen identified CoIII-salen catalysts with β-pinene- and α-naphthylalanine-derived chiral scaffolds with broad, yet complementary, substrate specificities.


Spin Alignment Generated In Inelastic Nuclear Reactions, Daniel Hoff 2018 Washington University in St. Louis

Spin Alignment Generated In Inelastic Nuclear Reactions, Daniel Hoff

Arts & Sciences Electronic Theses and Dissertations

The spin alignment of inelastically excited 7Li projectiles, when the target remains in its ground state, was determined through angular-correlation measurements between the breakup fragments of 7Li_ (_ + t). It was found that 7Li_ is largely aligned along the beam axis (longitudinal) in this type of inelastic reaction, regardless of the target. This longitudinal alignment is well described by DWBA calculations, which can be explained by an angular-momentum-excitation-energy mismatch condition. These calculations also explain the longitudinal spin alignment of excited nuclei in several other systems, showing the phenomenon is more general. The experiment involving 7Li was performed at the Texas ...

Learning Chemistry In English: Challenges Faced By Non-Native English Speakers, Arwa A. Alshehri

MSU Graduate Theses

Every year many international students come to study in the United States. In addition to all the challenges associated with coming to a new country, non-native English speakers (NNES) face the additional challenge of having to learn their content in English. Therefore, in this project, I recruited NNES participants from general chemistry courses since preliminary inquiries indicated that they have the largest enrollments. Because there were relatively few students at MSU who are non-native English speakers studying chemistry, I used a case study design to be able to extract generalizations from an in-depth study of a few individuals. The aim ...

Fast Identification Of Components Commonly Used In Homemade Explosives By Spectroscopic And Chemometric Methods, Deidre Day Vandenbos, Huggins Msimanga, Christopher Dockery 2018 Kennesaw State University

Fast Identification Of Components Commonly Used In Homemade Explosives By Spectroscopic And Chemometric Methods, Deidre Day Vandenbos, Huggins Msimanga, Christopher Dockery

Master of Science in Chemical Sciences Theses

Homemade explosives (HMEs) have become a global pandemic. This forensic research focuses on developing identification methods that can provide quick, cost effective, non-destructive analysis using portable instrumentation. These capabilities would be invaluable to first responders, military, and security officials to establish an evidentiary link between a suspect and a reference in cases of HMEs, IEDs, arson and environmental contamination.

Modern methods for quick identification of the fuels and oxidant sources used in manufacturing HMEs, include Fourier Transform Infrared (FT-IR) and Raman spectroscopy. Visual confirmation alone, however, is not strong enough to discriminate chemicals with nearly identical spectra, which occurs when ...

Predicting Spatial Patterns In Precipitation Isotope (Δ2h And Δ18o) Seasonality Using Sinusoidal Isoscapes, Scott T. Allen, James W. Kirchner, Gregory R. Goldsmith

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Understanding how precipitation isotopes vary spatially and temporally is important for tracer applications. We tested how well month‐to‐month variations in precipitation δ18O and δ2H were captured by sinusoidal cycles, and how well spatial variations in these seasonal cycles could be predicted, across Switzerland. Sine functions representing seasonal cycles in precipitation isotopes explained between 47% and 94% of the variance in monthly δ18O and δ2H values at each monitoring site. A significant sinusoidal cycle was also observed in line‐conditioned excess. We interpolated the amplitudes, phases, and offsets of these sine functions across the landscape ...

Detrital Protein Contributes To Oyster Nutrition And Growth In The Damariscotta Estuary, Maine, Usa, Cheyenne M. Adams

Electronic Theses and Dissertations

Oyster aquaculture is an expanding industry that relies on identifying and utilizing natural estuarine conditions for the economically viable production of a filter-feeding crop. The eastern oyster, Crassostrea virginica, is the principal species currently cultured in Maine. In addition to preferentially consumed phytoplankton, various detrital complexes (non-algal and/or non-living organic matter) may provide some nutrition to C. virginica between times of phytoplankton abundance. Here I investigated the importance of detrital proteins in supporting the growth of oysters cultured in the upper Damariscotta Estuary. Oyster aquaculture in this area is highly successful and previous reports indicate that labile detrital protein ...

Elemental Analysis Of Beer Manufactured In Virginia Satellite Breweries, Jennifer Wiliams

Student Scholar Showcase

Financial incentives from the state and wider distribution potential have lured many west coast brewers to open satellite breweries in Virginia. Quality control is crucial for any brewery and especially important in satellite breweries that need to imitate the standard set by the parent brewery. Zinc, magnesium, iron, sodium manganese, and calcium are trace elements found in wort and are essential for enzymes that catalyze fermentation reactions. These elements protect against cell stress, play a crucial role in flocculation, and can affect the flavoring and coloration of beer. Barley, water, and hops are the sources of these elements in beer ...

Metacognition And The Utility Of Pathway Maps In Introductory Chemistry, Kayla Schwartz

Honors Projects

Students historically struggle in introductory chemistry courses. This experiment was designed to test a hypothesized method to increase student success which utilized metacognition, reflection, and the creation of pathway maps. An introductory chemistry course at BGSU was given two sets of pre-assignments, pathway map assignments, and post-assignments which was related to the topics they were learning in class. The pre-assignments and post-assignments were used to determine if there was a change in understanding before and after the pathway map assignment was completed and the pathway map assignment was based on a question that was given in the pre-assignment. The students ...


Extraction And Identification Of Tomatidine In Cubanelle Peppers, Sadie Schultz, Madeleine Burkholder, Han Chang, Sydney Huffman 2018 Taylor University

Extraction And Identification Of Tomatidine In Cubanelle Peppers, Sadie Schultz, Madeleine Burkholder, Han Chang, Sydney Huffman

Chemistry Student Scholarship

Tomatidine is an aglycone commonly found in green tomatoes. Previous research suggests tomatidine and similar glycoalkaloids can inhibit the growth of cancer and promote the immune system. It has also been shown to act as an anti-inflammatory agent. Tomatoes are a part of the Solanaceae family and we decided to investigate to see if another member of that family also has the presence of tomatidine. We chose the Cubanelle peppers to be our subject of study because peppers are a common food and are closely related to green tomatoes.


A High Throughput Approach For The Generation Of Orthogonally Interacting Protein Pairs, Justin Lawrie, Xi Song, Wei Niu, Jiantao Guo 2018 University of Nebraska-Lincoln

A High Throughput Approach For The Generation Of Orthogonally Interacting Protein Pairs, Justin Lawrie, Xi Song, Wei Niu, Jiantao Guo

Faculty Publications -- Chemistry Department

In contrast to the nearly error-free self-assembly of protein architectures in nature, artificial assembly of protein complexes with pre-defined structure and function in vitro is still challenging. To mimic nature’s strategy to construct pre-defined three-dimensional protein architectures, highly specific proteinprotein interacting pairs are needed. Here we report an effort to create an orthogonally interacting protein pair from its parental pair using a bacteria-based in vivo directed evolution strategy. This high throughput approach features a combination of a negative and a positive selection. The newly developed negative selection from this work was used to remove any protein mutants that retain ...
