Title of Dissertation: Combinatorial Investigation of Intermetallics Using Electron-beam Deposition Hiroyuki Oguchi, Doctor of Philosophy, 2008 Directed By: Professor Ichiro Takeuchi, Materials Science & Engineering We have systematically studied subtle changes in physical properties of intermetallics using the combinatorial strategy where a large number of samples with systematically changed p...

This study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. Bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. The immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

Epitaxial graphene layers grown on single-crystal SiC have large structural coherence domains and can be easily patterned into submicron structures using standard microelectronics lithography techniques. Patterned structures show two-dimensional electron gas properties with mobilities exceeding 3 m2/Vs. Magnetotransport measurements (Shubnikov–de Haas oscillations) indicate that the transport p...

Large-area epitaxial graphene films were grown on cobalt by thermal cracker enhanced gas source molecular beam epitaxy. Growth conditions including growth temperature and growth time play important roles in the resulting morphology of as-grown films. High-quality graphene films can be achieved in a small growth window. Fast cooling rate was not required in this process due to direct growth mech...

The lipid bilayer component of biological membranes is important for the distribution, organization, and function of bilayer-spanning proteins. This regulation is due to both specific lipid-protein interactions and general bilayer-protein interactions, which modulate the energetics and kinetics of protein conformational transitions, as well as the protein distribution between different membrane...

background: defects in endoplasmic reticulum homeostasis are common occurrences in different diseases, such as diabetes, in which the function of endoplasmic reticulum is disrupted. it is now well established that ion channels of endoplasmic reticulum membrane have a critical role in endoplasmic reticulum luminal homeostasis. our previous studies showed the presence of an atp-sensitive cationic...

A thermal cracker enhanced gas source molecular beam epitaxy system was used to synthesize large-area graphene. Hydrocarbon gas molecules were broken by thermal cracker at very high temperature of 1200 C and then impinged on a nickel substrate. High-quality, large-area graphene films were achieved at 800 C, and this was confirmed by both Raman spectroscopy and transmission electron microscopy. ...

Deposition of behenic acid (B.A) mono and bilayers onto gold coated surfaces was performed by Langmuir-Blodget dip-casting technique. Surface Plasmon resonance (SPR) and ellipsometry methods were employed for investigation of the monolayer and bilayer films. The adsorption of the biologically important molecule Concanavalin A (Con A) from bulk solution to these monolayers and bilayers as we...
