Water Condensation Collection For Disaster Relief, Tyler Gaydosh Jan 2020

Water Condensation Collection For Disaster Relief, Tyler Gaydosh

Williams Honors College, Honors Research Projects

Numerous populations experience sudden, unexpected circumstances where drinking water supply may be compromised. Current leading response strategies include the delivery of disposable water bottles, a simple and effective way of meeting the demand of fresh drinking water. The lack of reusability results in problems with waste and cost. Any response to provide drinking water to a population in these circumstances must consider a prolonged crisis and these limitations: minimal delivery opportunities, power supply, and waste management (e.g., aftereffects of Hurricane Maria in Puerto Rico). A review of alternatives for water collection was done to determine a viable collection method that …

Filtration Apparatus Design For Oil-Water Separation Using Membranes And Sponges, Alec Jerger Jan 2020

Filtration Apparatus Design For Oil-Water Separation Using Membranes And Sponges, Alec Jerger

Williams Honors College, Honors Research Projects

It can be difficult to separate water and oil emulsions through traditional filtration. Therefore, investigations of filtering using thermo-responsive (TR) polymers, in this case poly(vinyl methyl ether) (PVME), was conducted. It’s hypothesized that below its lower critical solution temperature (LCST), PVME has an affinity for water while oil substances do not. Above the LCST the opposite will be true. To verify this hypothesis, iterations of filtration designs were created to provide optimum control over the parameters to measure flow. The final optimized experimental apparatus was a Chromaflex glass column which was air tight and controlled all parameters besides fluid flow. …


Effects Of Hofmeister Ions On Solubility And Swelling On Gelatin Hydrogels, Hannah Eldridge Jan 2020

Effects Of Hofmeister Ions On Solubility And Swelling On Gelatin Hydrogels, Hannah Eldridge

Reconsideration Of Energy Balance In Jiles–Atherton Model For Accurate Prediction Of B–H Trajectories In Ferrites, Harshita Singh, Scott D. Sudhoff Jan 2020

Reconsideration Of Energy Balance In Jiles–Atherton Model For Accurate Prediction Of B–H Trajectories In Ferrites, Harshita Singh, Scott D. Sudhoff

Department of Electrical and Computer Engineering Faculty Publications

In this article, the energy balance equation in the original Jiles-Atherton model is revisited. In particular, the assumption that the energy stored in a lossy material is equal to that stored in a lossless material is removed. This modification results in more accurate prediction of B -H trajectories. A new approach to characterize material parameters based on resonant response is also set forth. Extensive experimental validation is provided and model parameters for several common materials are given.


Impact Of Chain Architecture On The Thickness Dependence Of Physical Aging Rate Of Thin Polystyrene Films, Gregory Brown, Elizabeth Lewis, Bryan D. Vogt Jan 2020

Impact Of Chain Architecture On The Thickness Dependence Of Physical Aging Rate Of Thin Polystyrene Films, Gregory Brown, Elizabeth Lewis, Bryan D. Vogt

Williams Honors College, Honors Research Projects

The dynamics of polymer thin films have been demonstrated to be significantly altered from the bulk, but the origins of such differences are not well defined. In this work, we seek to understand the differences in the structural dynamics (or physical aging) of polystyrene (PS) through branching and other well defined architectures (comb and centipede). The aging dynamics of ultrathin films (< 30 nm) differ from relatively thick films (100-150nm) with linear PS thin films aging more rapidly than the relatively “bulk-like” thick films. Ellipsometric measurements are used to characterize the physical aging rate of the films. The change in film thickness and refractive index as the films are held below the glass transition temperature (Tg) provides a simple measure of the physical aging. In this study, four different architectures (linear, comb, 4 arm star, and centipede) will be investigated. For each PS architecture, the aging rate will be determined for film …

Non-Linear Non-Iterative Transient Inverse Conjugate Heat Transfer Method Applied To Microelectronics, David Gonzalez Cuadrado, Amy Marconnet, Guillermo Paniagua

CTRC Research Publications

Solving for temperature profiles given boundary conditions, geometry, and material properties is rela- tively straightforward given the wealth of analytical and computational techniques available. However, experimentally we often measure temperatures and seek to understand unknown boundary conditions or material properties. This problem is generally ill-posed. Thus, to get the value of these input param- eters, we use inverse methods: knowing the output of the system ( i.e. , temperature), we can compute the value of the unknown parameters ( e.g. , thermal conductivity or heat fluxes). In microelectronics, the location and magnitude of the boundary conditions including local heat generation …
