Corrosion Prevention On Aluminum Alloy, Andrea Brenner
Corrosion Prevention On Aluminum Alloy, Andrea Brenner
Symposium of Student Scholars
Aluminum alloy (Al-alloy) is a widely used metal in construction, aerospace, aviation, and other necessary fields due to its lightweight and tweakable properties. However, corrosion is inevitable on metals and alloys, and that causes millions of dollars of revenue loss every year. Therefore, we propose to research fabricating coating to prevent corrosion on Al-alloy. This study uses an iron-based metal-organic framework (MOF) and polyurethane (PU) based composite coating to prevent corrosion on the Al-alloy. The makeup of the composite material is changed by varying the percentage of MOF. In addition, a binder is also used to enhance the homogenization between …
Impact Of The Water Content In The Therapeutic Deep Eutectic Solvents, Noam Lewit, James Stewart, Oluseyi Olawuyi, Mohammed A. Halim
Impact Of The Water Content In The Therapeutic Deep Eutectic Solvents, Noam Lewit, James Stewart, Oluseyi Olawuyi, Mohammed A. Halim
Symposium of Student Scholars
Deep eutectic solvent(s) (DES) are the new generation of greener and more sustainable solvents, formulated by the complex of hydrogen bond in the molecules. The solvents allow us to achieve a significantly lower freezing point compared to its components, an affordable formulation and a technology that is typically formulated to improve the bioavailability of a drug. In this research project, we synthesized an ibuprofen-menthol based therapeutic deep eutectic solvent and investigated how water content affects the structure and dynamics of the solvent. For synthesizing the ibuprofen-menthol DES, 2.0629 g of Ibuprofen and 4.6881 g of menthol were placed in a …
Analysis Of Kavalactones In Various Consumptive Kava Samples Using Gc-Ms, Stephanie O'Kon
Analysis Of Kavalactones In Various Consumptive Kava Samples Using Gc-Ms, Stephanie O'Kon
Symposium of Student Scholars
Piper Methysticum, or Kava, is a plant native to the Pacific Islands and is used in various ceremonial and cultural aspects. In the United States, Kava has many dietary forms from sleep aids to mood boosters. The active ingredients found in Kava roots, kavalactones, give users psychoactive effects. However, there are concerns regarding toxicity and unknown safety consumption limits. There are six major kavalactones, and possibly more that have been reported, but not fully researched. The one of interest in this study is kavain. Different solvents, diethyl ether and acetone, have been used in extracting kavalactones from cut kava root. …
The Reactivity Of Metal Phosphites: Oxidative Rate Analysis, Jamie Kitchens
The Reactivity Of Metal Phosphites: Oxidative Rate Analysis, Jamie Kitchens
Symposium of Student Scholars
Phosphorous compounds are involved in many of the biomolecular processes deemed fundamental for life. DNA, ATP, and phospholipids are a few of the molecules where phosphates can be found in the body. Phosphates are geochemically characterized by their low solubility and poor reactivity. This has led to the investigation of reaction mechanisms that could lead to the formation of the phosphorous compounds found in organisms. The oxidation of phosphite into phosphate could be how phosphates were introduced to life, due to phosphites being more soluble and more reactive than phosphates. We will present the synthesis and oxidation reactivity of four …
Electrochemical And Spectroscopic Characterization Of Cerium Salts And Nanoceria Material, Emily Velarde, Wei Zhou
Electrochemical And Spectroscopic Characterization Of Cerium Salts And Nanoceria Material, Emily Velarde, Wei Zhou
Symposium of Student Scholars
The nanoscale form of cerium oxide, nanoceria (nano-CeOx), has drawn great attention in recent years in electrochemical, nanomaterial research and medicinal studies due to its antibacterial properties, UV absorption, and its biochemical function as possible radical scavenger. Many new synthesis methods have achieved uniform and biocompatible nanoceria particles, and our lab has created cerium oxide particles that shows UV/Vis. absorption and X-ray patterns similar to the commercial nanoceria and nanoceria made in other research laboratories with novel synthetic methods.
This study focuses on charactering and comparing electrochemical properties of cerium inorganic salts and synthesized nanoceria. Preliminary results …
Bioanalytical Determination Of Glucose Concentration In Sports Drinks Using Uv/Vis Spectroscopy, Laney Hedgeman, Brianna Bond
Bioanalytical Determination Of Glucose Concentration In Sports Drinks Using Uv/Vis Spectroscopy, Laney Hedgeman, Brianna Bond
Symposium of Student Scholars
Abstract
The purpose of our project is to indirectly monitor the enzymatic activity of glucose oxidase as it reacts with the glucose present in sports drinks through the quantitative analysis of the generated ferricyanide. As glucose oxidase catalyzes the oxidation of beta-D-glucose in the presence of oxygen, D-glucono-1,5-lactone is produced along with hydrogen peroxide. The hydrogen peroxide is used in a subsequent reaction with ferrocyanide catalyzed by horse radish peroxidase to produce water and the chromophore ferricyanide. This compound absorbs in the ultraviolet/visible spectrum at 420 nm, which can be quickly measured using Ultraviolet/Visible Spectroscopy. Since the molar ratio of …
