Forked Shaped Rebound Droplet for Impingement on Anisotropic Superhydrophobic Surfaces

by

David Bilodeau and Dr. Daniel Maynes, Department of Mechanical Engineering Background Many metals rust when exposed to moisture and that rusting can cause the item that is made of that metal to break down. A superhydrophobic surface can repel liquids and keep metals from rusting longer. Superhydrophobic surfaces have existed in nature for a long […]

Measurement of Steel Corrosion in Bridge Decks by Impedance Spectroscopy

by

Paul Bartholomew and Dr. Brian Mazzeo, Department of Electrical and Computer Engineering On bridge decks, a specified thickness of concrete cover, usually between 2.0 and 3.0 in., is provided over the embedded reinforcing steel as a protective layer. When chloride ions penetrate the concrete cover, corrosion of the reinforcement can occur [1, 2, 3]. Corrosion […]

SCOS Calibration and Filtering for HPM Field Measurement

by

Bradley Whitaker and Dr. Stephen Schultz, Department of Electrical and Computer Engineering High power microwave (HPM) weapons create large electric and magnetic fields with the purpose of disrupting electronic equipment. In order to protect electronics, the interaction between the equipment and the electromagnetic fields must be characterized. This requires a noninvasive sensor that can detect […]

Instrumentation and Monitoring of Concrete Bridge Decks: Moisture, Temperature, and Electrical Conductivity

by

Tenli Waters and Dr. Spencer Guthrie, Department of Civil and Environmental Engineering The purpose of this report is to give the results of research conducted to measure the extent of internal curing occurring in the field in concrete bridge decks constructed using lightweight concrete compared to conventional concrete. With permission from bridge engineers at the […]

Scaffold Design of a Novel Nano-Particle for Single-Target Imaging

by

Chad Varner and Dr. Brad Bundy, Department of Chemical Engineering The purpose of this project has been to help develop a novel nano-imaging particle. Current methodologies have limitations that preclude them from being used for nanometric (1-500nm) imaging processes in living organisms. These include, but are not limited to, low signal to noise ratios, limited […]

Assessing the Impact of the Approximations Used in the Development of the Pulsed Laser Method for Measuring Thermal Diffusivity

by

Trevor Terrill and Dr. Matthew Jones, Department of Mechanical Engineering Project Overview The purpose of this project was to conduct a rigorous investigation of each of the approximations made in the development of the pulsed laser method for measuring the thermal diffusivity. Thermal conductivity is an important engineering parameter, but measuring it directly is difficult. […]

Silver Flash: A MEMs Memory Device

by

John Stout and Dr. Aaron Hawkins, Department of Electrical Engineering The silver flash project is an effort to create a reliable, MEMs based memory device. As a joint electrical and mechanical structure these devices offer several advantages over the traditional NAND flash memory currently found in phones, mp3 players, and USB memory drives. The silver […]

Influence of Tissue Stiffness Asymmetry on Human Vocal Fold Vibration

by

Kimberly Stevens and Dr. Scott Thomson, Department of Mechanical Engineering Background and Motivation The flow-induced vibration of the human vocal folds produces the sound for voiced speech and singing. The vocal folds consist of two folds of tissue, one on each side of the larynx, that are nominally symmetric in terms of shape, composition, and […]

An Alternative Method to Prepare Cobalt Catalysts Using Salt Precursors

by

Trevor Seegmiller and Dr. Calvin Bartholomew, Department of Chemical Engineering Fischer-Tropsch synthesis (FTS) is the process for converting syngas (carbon monoxide and hydrogen) into liquid fuels such as gasoline and diesel. A cobalt or iron catalyst is required for the process. Cobalt catalysts have the highest effectiveness and stability in FTS; however, they are more […]

Research and Design of Transtibial Prosthetic Shower Legs

by

Angelina Schwartz and Dr. Eric Homer, Department of Mechanical Engineering The aim of 2ft Prosthetics is to design, test, and distribute low-cost prostheses to below-the-knee amputees in developing countries. To do this, a research and development team focuses on the design and construction of the prosthesis. It is then tested on local amputees by the […]
