Correlating Wet-Sample Electron Microscopy With Light Scattering Spectroscopy On The Example Of Polymeric Microgels, Christian Gunder
Correlating Wet-Sample Electron Microscopy With Light Scattering Spectroscopy On The Example Of Polymeric Microgels, Christian Gunder
Undergraduate Research Posters 2016
Amphiphilic cellulose-based microgels with a reversible volume-phase transition at around 40.5°C—the low critical solution temperature (LCST)—have been synthesized, characterized, and optimized. After carefully planned synthesis and filtering the samples with a 0.22μm filter microgels were characterized with dynamic light scattering (DLS), yielding reproducible results for the radii of particles around 100-120 nm below the LCST and 60-70 nm above it. Through the use of scanning electron microscopy (SEM), air dried samples and wet samples were also analyzed. Air dried samples were dried for 24 hours until all water was evaporated, ensuring the collapse of microgels as if they were expelling …
Effects Of Flanking Bigrams On Decision Performance In Selective And Divided Attention Tasks, Nicole Russo, Jamie Rodman
Effects Of Flanking Bigrams On Decision Performance In Selective And Divided Attention Tasks, Nicole Russo, Jamie Rodman
Undergraduate Research Posters 2016
In previous research, lexical decision performance for word targets flanked by pairs of letters was better when flankers consisted of letters in the target (e.g., BI BIRD RD; RD BIRD BI; IB BIRD DR; DR BIRD IB) than of non-target letters (e.g., CE BIRD NT). Also, performance was better when flankers contained letters ordered as in the target (e.g., BI BIRD RD; RD BIRD BI) than switched (e.g., IB BIRD DR; DR BIRD IB), but flanker order relative to the target did not affect performance. That flankers affect lexical decision performance indicates that participants do not attend selectively to the …

Disorders comprised of intellectual and developmental disabilities (IDD) as a group are comprised of autism spectrum disorders, Down syndrome, and various genetic conditions that stunt the intellectual and functional development of an individual. These disorders affect roughly 14% of families in the US (Boyle et al., 2011), which approximates to seven million households in the US. The presence of IDD in a child is often associated with increased stress for the parents, given that IDD is often accompanied by behavioral problems in the affected child. Surprisingly, relatively little work has been done on the effects of IDD on typically developing …
How Does Educational Opportunities Influence Decisions For Nigerian Girls And The Society?, Shalonda Swanson
How Does Educational Opportunities Influence Decisions For Nigerian Girls And The Society?, Shalonda Swanson
Undergraduate Research Posters 2016
This paper raises questions about educational opportunities for Nigerian girls to understand if traditional Islamic or Western education influence the girls on various factors; including, their religious connections, optimism for their future, and the value in Islamic education compared to Western education. To discuss the current status of the country the paper discusses the historical underlying factors that influenced Nigeria's policies for educational opportunities for girls. Nigeria has struggled with gender disparities that disproportionately provided educational opportunities for boys at an increased rate compared to girls. This research reports the traditional values that restricted girls' access to education and the …
Life Behind Glass: Bioreactor Studies On The Salt-Water Adaptation Of Scenedesmus Dimorphus, Joshua Hartranft, Alex Fedai, Sahar Ataya
Life Behind Glass: Bioreactor Studies On The Salt-Water Adaptation Of Scenedesmus Dimorphus, Joshua Hartranft, Alex Fedai, Sahar Ataya

Algae has considerable promise as source for liquid biofuel because of high productivity and because algae farms do not compete with food crops for arable land. Freshwater algae is preferred over saltwater algae because of the higher lipid content in the former. Unfortunately, freshwater algae “farms” would require a vast amount of fresh water, and given the scarcity of fresh water, this is not a viable long-term solution. Therefore, the adaption of a fresh-water species of algae to a salt-water environment is a potential solution. In this study, it was shown that the growth rate of the freshwater algae S. …

Since fossil fuels are decreasing over time an alternative energy source will be soon required. The algae, Scenedesmus dimorphus, grows in freshwater and is known for its fast growth of glycerolipid content which is used for biodiesel production. After the algae is grown in optimal conditions, the released fatty acids and glycerolipids are transformed into fatty acid methyl esters (FAMEs) which are used as biodiesel. The FAMEs were quantitatively determined by gas chromatography mass spectrometry (GC-MS) to determine the total glycerolipid content in the different algae samples. The samples that were analyzed include freshwater controls and saline adapted samples. Analysis …
Design And Fabrication Of A Microfluidic Device Using A 3d Printer, Aaron Smith
Design And Fabrication Of A Microfluidic Device Using A 3d Printer, Aaron Smith
Undergraduate Research Posters 2016
The goal of this work was to design and implement a microfluidic mixer-based chemical reactor using a 3-D printer. Microfluidic devices are very useful for processes that use expensive reactants or require a high level of control, and we hypothesize that the ability to develop a prototype using a 3-D printer would lower their costs and help overcome some of the limitations of soft-lithography based devices. One-level and two-level designs were made using SolidWorks® software, and various stages of the model were printed on Objet® and FDM® printers. The Objet printer offers the advantage of printing a prototype using a …

Light Scattering Characterization Of Elastin-Like Polypeptide Trimer Micelles, Ilona Tsuper, Daniel Terrano, Adam Maraschky
Undergraduate Research Posters 2016
Elastin-Like Polypeptides (ELP) can be used to form thermo-reversible vehicles for drug delivery systems. The ELP nanoparticles are composed of three-armed star polypeptides. Each of the three arms extending from the negatively charged foldon domain includes 20 repeats of the (GVGVP) amino acid sequence. The ELP polymer chains are soluble at room temperature and become insoluble at the transition temperature (close to 50 oC), forming micelles. The size and shape of the micelle is dependent on the temperature and the pH of solution, along with the concentration of the Phosphate Buffered Saline (PBS) solvent. The technique of Depolarized Dynamic Light …

Temperature sensitive nanoparticles (E20F) were generated from a construct of three chains of Elastin- Like Polypeptides (ELP) linked to a negatively charged foldon domain. This ELP system was mixed at different ratios with a single linear chain of ELP (H40L) which was deprived of the foldon domain. The mixed system is soluble at room temperature and at a transition temperature will form swollen micelles with the hydrophobic linear chains hidden inside. This system was studied using Depolarized Dynamic Light Scattering (DDLS) and Static Light Scattering (SLS) to model the size, shape, and internal structure of the mixed micelles. The mixed …

Anisotropic nanoparticles, such as carbon nanotubes and noble metal nanorods, have excellent electrical, mechanical, and thermal properties. This work examined techniques for the nanopatterning of silicon substrates for the subsequent deposition of anisotropic nanoparticles in order to exploit their properties in macroscopic applications. Argon-ion-sputter induced rippling of Si (100) as well as a microparticle mask were examined as methods for templating a silicon substrate. For the ion-sputter
