Multicellular monolayer’s self-organization under external stimuli

Creator:: Li, Guanyu
Abstract:: Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...

Molecular Packing-Dependent Exciton and Polari on Dynamics in Anthradithiophene Organic Crystals

Creator:: Van Schenck, Jonathan D. B., Giesbers, Gregory, Kannegulla, Akash, Cheng, Li-Jing, Anthony, John E., and Ostroverkhova, Oksana
Abstract:: Polarization-dependent absorption spectra of two functionalized derivatives of fluorinated anthradithiophene, diF TES-ADT and diF TDMS-ADT, were studied in the crystal phase using a Holstein-like Hamiltonian. For both molecules, the primary contribution to the lowest energy absorption was found to be the S-0-S-1 excitonic transition perturbed by an intermolecular coupling of...

Synthesis and charge transport studies of stable, soluble hexacenes

Creator:: Purushothaman, Balaji, Parkin, Sean R., Kendrick, Mark J., David, Daniel, Ward, Jeremy W., Yu, Liyang, Stingelin, Natalie, Jurchescu, Oana D., Ostroverkhova, Oksana, and Anthony, John E.
Abstract:: Acenes larger than pentacene are predicted to possess enticing electronic properties, but are insoluble and prone to rapid decomposition. Utilizing a combination of functionalization strategies, we present stable, solution processable hexacenes and an evaluation of their hole and electron transport properties.

Nonlinear Photocarrier Dynamics in Multilayer WSe2 Induced by Intense Terahertz Pulses

Creator:: Guay, Viela, Johnson, Nathan, Zhang, Yue, Van Der Zande, Arend M., Thorp, Spencer G., Graham, Matthew, and Lee, Yun-Shik
Abstract:: Non-equilibrium photocarriers in multilayer WSe2 injected by femtosecond laser pulses exhibit extraordinary nonlinear dynamics in the presence of intense THz fields. The THz absorption in optically excited WSe2 rises rapidly in the low THz field regime and gradually ramp up at high intensities. The strong THz pulses drive the photocarriers...

A nanoscale pn junction in series with tunable Schottky barriers

Creator:: Aspitarte, Lee, McCulley, Daniel R., and Minot, Ethan D.
Abstract:: PN junctions in nanoscale materials are of interest for a range of technologies including photodetectors, solar cells, and light-emitting diodes. However, Schottky barriers at the interface between metal contacts and the nanomaterial are often unavoidable. The effect of metal-semiconductor interfaces on the behavior of nanoscale diodes must be understood, both...

In silico screening of nanoporous materials for gas sensing and separation

Creator:: Gantzler, Nickolas
Abstract:: The utility of high-throughput, computational screening has become an invaluable asset to the field of materials science. In the hierarchy of computational methods, the most accurate methods are often the most computationally expensive. However, as both the efficiency and fidelity of numerical techniques advance, high-quality screening of large materials datasets...

A potential model investigation of the low-energy antikaon-nucleon interaction and antikaon-nucleus bound states

Creator:: Schnick, Jeffrey W.
Abstract:: The parameters of separable coupled channels s-wave potentials for the strong KN interaction are determined from low energy K⁻p scattering data with additional constraints from π⁻p π∑K° production data. The shifts and widths of the Coulomb bound states in kaonic hydrogen are calculated with these potentials and compared with experiment....

New computational methods for determining antikaon-nucleus bound states

Creator:: Fink, Paul J., 1954-
Abstract:: Optical potential for antikaon-nucleus strong interactions are constructed using elementary antikaon-nucleus potentials determined previously. The optical potentials are used to determine the existence of a kaon hypernucleus. Modern three dimensional visualization techniques are used to study model dependences, new methods for speeding the calculation of the optical potential are developed,...

Sub-diffraction light propagation and imaging in planar negative refraction waveguides

Creator:: Wangberg, Robyn
Abstract:: In this dissertation we study the electromagnetic properties of planar waveguides with non-magnetic strongly anisotropic dielectric cores. We develop an analytical description of the mode propagation in these systems and show that the index of refraction can be either positive or negative depending on the specific material parameters. Propagating modes...
