Can CP Be Less Than CV?, Yingbin Ge, Samuel L. Montgomery, Gabriel L. Borrello 2021 Central Washington University

Can CP Be Less Than CV?, Yingbin Ge, Samuel L. Montgomery, Gabriel L. Borrello

All Faculty Scholarship for the College of the Sciences

Can CP be less than CV? This is a fundamental question in physics, chemistry, chemical engineering, and mechanical engineering. This question hangs in the minds of many students, instructors, and researchers. The first instinct is to answer “Yes, for water between 0 and 4 °C” if one knows that water expands as temperature decreases in this temperature range. The same question is asked in several Physical Chemistry and Physics textbooks. Students are supposed to answer that water contracts when heated at below 4 °C in an isobaric process. Because work is done to the contracting water, less heat ...


A Novel Molecular And Cellular Study On Curcumin, Khang Nguyen 2021 Stephen F Austin State University

A Novel Molecular And Cellular Study On Curcumin, Khang Nguyen

Undergraduate Research Conference

Since the discovery of G-quartet (G4)by M. Gellertin 1962, much attention has been given on G4and C4(also called i-motif) as important drug design targets for the treatment of various human disorders. G4 forming sequences are prevalent in human genome, which includes many important regions of the eukaryotic genome, such as telomere ends, regulatory regions of many oncogenes c-kit, proto-oncogene c-myc, Kirsten rat sarcoma viral oncogene homolog (KRas). Curcumin(diferuloylmethane), an antiinflammatory and antioxidant compound, is found in the rhizomes of the plant Curcuma longa. The phytopolyphenolic chemical curcumin has been in the prominence due to its diverse pharmacological ...

Study Of Potential Drug For Alzheimer’S Disease: Small Organic Molecules, 1,5-Dhn And Tmpyp Inhibit Amyloid-Β Peptide Aggregation And Quench Hydroxyl Radicals, Matthew Murphy 2021 Stephen F Austin State University

Study Of Potential Drug For Alzheimer’S Disease: Small Organic Molecules, 1,5-Dhn And Tmpyp Inhibit Amyloid-Β Peptide Aggregation And Quench Hydroxyl Radicals, Matthew Murphy

Undergraduate Research Conference

Alzheimer disease (AD) is recognized as the six leading cause of the death in the United States. As of now, there is no cure for this fatal disease. The current treatment methods can only temporarily slow the worsening of symptoms. Research data suggested that an excess generation of hydroxyl radical in the brain causing the aggregation of Amyloid-β (Aβ) peptide which is considered to be responsible for Alzheimer's disease. Thus, there is a pressing need to find a suitable drug which can quench hydroxyl radicals effectively and stop or slow down the formation of aggregation of Aβ peptide. The ...

Nitro Group Reduction For Use In Organic, Cathodic Materials, Brock G. Goeden 2021 University of South Dakota

Nitro Group Reduction For Use In Organic, Cathodic Materials, Brock G. Goeden

Honors Thesis

The industrial demand for higher capacity, light-weight battery materials has skyrocketed in recent years due to heavy investments in portable electronics, electronic vehicles, and renewable energy sources. However, rechargeable battery technology has seen little improvement since the invention of the Lithium-Ion battery in the 1980s. The low energy density of the traditionally utilized LiCoO2 cathodic material (specific capacity: 272 mAh g-1), has limited its potential to meet these increasing demands. To solve this problem, our research group is investigating new types of lightweight, organic, polymeric materials with conductive backbones as a possible replacement for the cathodic materials in Lithium-Ion batteries ...


A Spectroscopic And Computational Study Of Diacetyl And Water Clusters, Margaret Baldwin 2021 University of Mississippi

A Spectroscopic And Computational Study Of Diacetyl And Water Clusters, Margaret Baldwin

Honors Theses

Diacetyl, otherwise known as 1,2-butadione or biacetyl, is a flavor additive used in microwave popcorn, and more importantly as of late, e-cigarettes. The compound is known to cause lung disease for those who have been exposed to a large quantity of the buttery smelling molecule. As such, the characterization of diacetyl’s vibrational modes when it interacts with water are pivotal to understanding the effects it has on human lung tissue. In this research, the intermolecular interactions between water and diacetyl and the effects they have on one another’s vibrational modes are explored. While some experimental data is ...

Campus Research Day

The application of this molecule can be used eventually to add several elements like (Bromine, Chlorine, etc.) Previous done research that was conducted was in shortening the process to synthesize PAH. Since then, there has been research conducted to stabilize the compound by closing/linking two of the un-linked benzene rings.
