The Effects Of Salinity And Acetaminophen On The Aquatic Snail Physa Acuta, Michelle Sackey-Ansah, Megan Mackey, Daniel Elias, Jason Doll, Alyssa Brookhart
The Effects Of Salinity And Acetaminophen On The Aquatic Snail Physa Acuta, Michelle Sackey-Ansah, Megan Mackey, Daniel Elias, Jason Doll, Alyssa Brookhart
Journal of the South Carolina Academy of Science
Pharmaceuticals are increasingly detected in water bodies, and their presence can negatively impact aquatic organisms. This effect can be amplified when combined with increasing salinity in freshwater ecosystems. Acetaminophen is a widely used analgesic that is commonly found in river, streams, and waters where it is discharged directly. Therefore, organisms present in these locations (e.g., insects, snails, amphibians, and fish) are likely to be affected by acetaminophen. In this study, we determined the effects of elevated salinity (0.68 g/L), acetaminophen (500 µg/L) and combined elevated salinity (0.68 g/L) and acetaminophen (500 µg/L), on the growth, reproduction, and movement of the …

The Effect Of Alcalase Concentration On The Proteins From The Shells Of Litopenaeus Setiferus (White Shrimp), Liam T. Quan
The Effect Of Alcalase Concentration On The Proteins From The Shells Of Litopenaeus Setiferus (White Shrimp), Liam T. Quan
Journal of the South Carolina Academy of Science
Chitin is a naturally abundant polymer that also happens to be biodegradable. Chitin can be used in a variety of different products such as biodegradable plastics, papers, medical products, foods, and medical treatments. To extract chitin, shells must be demineralized and deproteinized. The goal of this experiment was to examine the effect of the protease Alcalase in the deproteinization of litopenaeus setiferus shells. The hypothesis was that if the concentration of Alcalase increased, then the absorbance of proteins in the spectrophotometer reading would increase. The null hypothesis was that if the concentration increased there would be no change in absorption. …

In Situ Monitoring Of Catalytic Molecular Transformations On Noble Metal Nanocatalysts Using Surface-Enhanced Raman Spectroscopy, Hui Wang, Qingfeng Zhang, Esteban Villarreal, Hao Jing, Kexun Chen
Journal of the South Carolina Academy of Science
Noble metal nanoparticles have long been of tremendous interest in the nanophotonics and nanocatalysis communities owing to their intriguing size- and shape-dependent plasmonic and catalytic properties. The combination of tunable plasmon resonances with superior catalytic activities on the same noble metal nanoparticle, however, has long been challenging because the research on nanoplasmonics and nanocatalysis deals with nanoparticles in two drastically different size regimes. While tunable plasmon resonances are a unique feature of metallic nanoparticles in the sub-wavelength size regime, heterogeneous catalysis requires the use of substrate-supported sub-5 nm nanoparticulate catalysts. In this mini-review article, we share with the readers several …

Synthesis Of Stimuli-Responsive Programmable Polymers Through Ring-Opening–Metathesis Cross-Metathesis (Rom-Cm), Courtney S. Dziewior, Sharon M. S. Strickland, Ping Li, Ken D. Shimizu
Journal of the South Carolina Academy of Science
Stimuli-responsive polymers can change their physical and/or chemical properties in response to external stimuli. These polymers have found great success in a number of important areas including molecular gels and biomedical engineering, as well as success in applications such as targeted drug delivery and biosensors. We have been working toward the development of programmable polymers that remember the response after a stimulus is withdrawn. To this end, we set out to synthesize specific functional monomers. While different types of reactions could potentially result in the desired target monomer, we studied the ring-opening metathesis–cross-metathesis reaction (ROM-CM). Previous work of ours synthesized …

The Effect Of Confinement On Fe2o3 Nanoparticles In Free Diffusion And With A Horizontal Magnetic Field, Patrick Simonson, Ashely Rice, Gabrielle Seymore, Ana Oprisan
Journal of the South Carolina Academy of Science
We investigated the magnitude of the confinement effect's influence on the free diffusion of Iron Oxide Fe2O3 in pure water contained in cells of different volumes and also that of an applied magnetic field. A shadowgraph apparatus consisting of a super luminous diode (SLD) source, a CCD camera, and achromatic lenses was used to record and analyze the changing indices of refraction due to the presence of concentration-driven fluctuations as the solution diffuses. Extracted frames from this recording were processed through a Differential Dynamic Algorithm (DDA) that determined the dynamics of the process, such as the structure …

Studying Near-Critical And Super-Critical Fluids In Reduced Gravity, Christian Hawkins, Ana Oprisan, Carole Lecoutre-Chabot, Yves Garrabos, Daniel Beysens
Journal of the South Carolina Academy of Science
Critical and supercritical fluids have a variety of applications, from use as machine lubricants in high pressure or high temperature environments to the manufacturing of materials such as aerogel. The optical properties of fluids undergo rapid changes near the critical point resulting in a rapid increase in turbidity known as critical opalescence. These optical changes can be used to probe the universality of critical behavior. As a fluid approaches the critical point, the compressibility rapidly increases. In a gravitational field, this increase in compressibility leads to near-critical fluids stratifying by phase and density, making it difficult to observe the optical …

The Effect Of Vinegar And Tap Water On The Release Of Nickel In Grade 304 Stainless Steel Cups, Caroline Quan
The Effect Of Vinegar And Tap Water On The Release Of Nickel In Grade 304 Stainless Steel Cups, Caroline Quan
Journal of the South Carolina Academy of Science
Consumption of nickel rich liquids and foods pose a risk to human health, possibly causing reactions such as dermatitis. This study examines the amount of nickel that leaches out of grade 304 stainless steel cups with respect to time. The hypothesis of this experiment is that if given enough time, the liquids will react to the nickel in the stainless steel cups, and then nickel will leach out into the cup’s contents. The null hypothesis being that if the cups, since they are not given enough time and/or do not react to the nickel in the stainless steel cups, will …
