Bilayer Network Modeling
… membrane potentials and ion currents through a bilayer network system. The modeling platform builds off of work performed by Hodgkin and Huxley in modeling cell membrane potentials and ion currents with electrical circuits. This modeling platform is built specifically for cell mimics where …

Theory of Bilayer Graphene Spectroscopy.
… we model theoretically spectra measured for bilayer graphene obtained using the angle-resolved photoemission spectroscopy, magneto-optical absorption spectroscopy and electronic Raman spectroscopy The theories are based on the tight-binding description of the pi bands in the material. In …

Studies of bilayer and trilayer graphene
… a material with high potential for applications. Bilayer graphene (2LG) and trilayer graphene (3LG) share many of the interesting properties of its monolayer relative, but with several key differences. This thesis makes use of resonant Raman spectroscopy to characterize these systems and quantify …

The Bilayer Polymer Light-Emitting Electrochemical Cells
… layer and the electrolyte layer, creating a bilayer LEC. In my thesis, multiple studies were conducted to explore whether the thickness of the luminescent polymer layer changes the performance of the bilayer LEC, the development of a blue bilayer LEC, and examining a different bilayer LEC …

Buckling patterns on pre-stretched bilayer shells
… from the biaxial compression of elastomeric bilayer shells. After fabricating our samples, releasing the pre-stretch in the substrate by deflation places the outer film in a state of biaxial compression and yields a variety of buckling patterns. We systematically explore the parameter space …

Quantum Hall transport in graphene and its bilayer
… with a peculiar Landau Level at zero energy. In bilayer graphene, the Dirac-like quadratic energy spectrum leads to an equally interesting, novel integer quantum Hall effect, with a eight-fold degenerate zero energy Landau level. In this thesis, we present transport studies at high magnetic field …

Incorporation and analysis of bilayer constituents in nanodiscs
… engineered lipoparticles composed of a lipid bilayer and two surrounding amphipathic proteins, have been utilized to house and solubilize integral membrane proteins and other molecules with large hydrophobic groups which limit their aqueous solubility. In the experiments described herein, …

Analysis and implementation of the bilayer microfluidic geometry
… In this thesis, we will consider a membrane bilayer device configuration in which the transport of a solute to a cell population is achieved by flowing solute through a proximate channel separated from the culture channel by a membrane and seek to characterize some of its hydrodynamic and …

Electronic transport in low-angle twisted bilayer graphene
… is developed to reliably produce twisted bilayer graphene with controlled angle, and electronic transport measurements of the resulting high-quality samples are performed and discussed. We discover novel insulating states that purely results from the moiŕe superlattice band structure. The …

Phase coherence in the regime of bilayer exciton condensation
At a total filling factor of one two closely-spaced two-dimensional electron systems (2DES) can be viewed as a Bose-Einstein condensate of excitons, where electrons from one 2DES couple to vacant states from the other 2DES. The pairing of electrons and holes (i.e., excitons) is mediated by Coulomb …

Investigating Cholesterol Orientation in Lipid Bilayer by Raman Spectroscopy
… are understood in part, how the phospholipid bilayer in cells accommodates the different processes for the copious types of proteins is not fully understood. Cholesterol however has been proven to play a key role in animal membrane functions. By using gold nanorods as a substrate, lipid …

Photoelectric Characterization of Bacteriorhodopsin Reconstituted in Lipid Bilayer Membrane
… a system was built to characterize the lipid bilayer membranes and to measure the photocurrent. The lipid bilayer membrane was characterized by its capacitance and resistance. A picoampere photocurrent was observed when Bacteriorhodopsin protein was present in the bilayer membrane and a 532 nm …

Quantum many body physics in single and bilayer graphene
… in doped graphene. Next, we study bilayer graphene (BLG), which has a non-vanishing density of states even at charge neutrality. We show that Coulomb interactions give rise to a zero bias anomaly in the tunneling density of states for BLG, which manifests itself at high energy …

Lipid Bilayer Formation in Aqueous Solutions of Ionic Liquids
The formation of lipid bilayer membranes between droplets of ionic liquid is presented as a means of forming functional bimolecular networks for use in sensor applications. Ionic liquids are salts that have a number of useful properties, such as low melting points making them liquid at room …

Stability analysis of a bilayer contained within a cylindrical tube
Airways in the lung are coated with a liquid bilayer consisting of a serous layer adjacent to a more viscous mucus layer which is contiguous with the air core. An instability due to surface tension at the interfaces may lead to the formation of a liquid plug that blocks the passage of air. This is …
