Incorporation of plasma into CVD graphene growth
Graphene is a 2D crystalline sheet of Carbon bonded together in a hexagonal lattice. Its unique structure gives it valuable optical and electrical properties that could be used in nanoelectronics or other fields. Current methods for graphene production do...

Removal of trace krypton from xenon using charcoal chromatography in the saturated regime
Liquid xenon experiments are becoming more prominent as a viable way to search for dark matter. In these experiments, it is important to use liquid Xenon free of any radioactive...

Capacitive level sensors for use in liquid xenon detectors
The LUX dark matter experiment liquid xenon detector uses an electric field created by grids to increase the drift velocity of electrons into xenon gas causing them to produce additional scintillation photons. These photons...

Creating an “on-sky” test environment for CMB detector arrays
Measuring Cosmic Microwave Background Radiation polarization anisotropies requires that detectors be held at extremely low temperatures (~.3K) in order to prevent noise. Cooling detectors to such temperatures in the laboratory is not a difficult task, but in...

Conductors as a model for elliptical coffee stains
In electrostatics, conductors exhibit a number of interesting properties. Among these is the ‘lightning rod’ effect, whereby electric fields are significantly greater near areas of high curvature. In 1997, Nagel et al. published a paper likening the behavior...

Observing lake Erie algae blooms via hyper spectral imaging on CubeSat
The goal of this project is to develop a miniaturized multi/hyper-spectral imaging instrument that could be integrated within a CubeSat to provide orbital observations of Lake Erie algae blooms in late summers....

Photobleaching of fluorescent dyes in polymer films
Recently, optical data storage has been achieved via photobleaching of a fluorescent dye in co-extruded, multilayer, polymer films. Photobleaching, the decrease in fluorescence by exposure to light, can be caused by a number of different processes,...

Computer Controlled Temperature Programmed Desorption from Noble Metal Surfaces
Temperature Programmed Desorption (TPD) provides insight that no other spectroscopy can give into the interactions between molecules and the surfaces on which these molecules are adsorbed. TPD is performed in an ultrahigh vacuum (UHV) environment, ~...

Aluminum zinc oxide transparent conductors for optical cavity enhanced polymer photovoltaics
Indium tin oxide is the ubiquitous transparent conductor used in all liquid crystal displays and thin film photovoltaic devices. Indium, however, is a rare and relatively expensive material, leading to intense research to replace it...
