Finite-Element Analysis of Low-Power Laser Heating in Gold::Vanadium Dioxide Nanocomposites
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
Finite element modeling was performed using COMSOL Multiphysics to study the
thermal dynamics of gold::vanadium dioxide (VO$_{2}$) nanocomposites. These
simulations were done to understand the data from transient ...
Reflection and rotation for three dimensional microscopy of live cells
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-18)
Confocal scanning laser microscopy and multiphoton microscopy provide 3D data from biological specimens, but with limited z-axis precision. Multiple microscale mirrors can be used to obtain more accurate 3D data on living ...
Influence of patient size on dose to female breast tissue during routine computed tomography scans
(Vanderbilt University. Dept. of Physics & Astronomy, 2008-04-21)
Monte Carlo methods are well suited to the evaluation of radiation transport phenomena. The scalable phantoms employed in this project permitted rapid creation of three models of similar geometry, but different body habitus. ...
Micro Programmable Object Navigation Gadget (micro-PONG) for Studying Electroosmotic Flow in PDMS Microchannel
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
Precise control of fluid delivery in analytical devices may be achieved by harnessing electroosmotic flow (EOF) in oxidized
poly(dimethylsiloxane) microfluidic channels fabricated via soft lithography. However, the ...
Engineering a perfusion-enabled mechanical compressor for long-duration immobilization and microscopy of cells and small organisms
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
The study of living specimens is essential to the understanding of
organismal behavior. Unfortunately, a major difficulty in the study of
live organisms is that many move in and out of the field of view or
focal plane ...
Perturbation Theory for Thin Cladding Layers on Silicon Photonic Systems
(Vanderbilt University. Dept. of Physics and Astronomy, 2011-04)
I develop a perturbation theory for resonant frequency shifts caused by thin
layer of material added to dielectric systems. This development can be used
to effectively model photonic surface-sensing systems, which use ...
Real-time real-space density functional theory calculations of electron scattering in materials
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)
Density functional theory is utilized in real-time,
real-space simulations of LEED measurements and attosecond electron
scattering. For LEED measurements, we find that our simulation results
agree well with experimental ...
Measurement of Energy Spectrum of Electrons Field-Emitted from Diamond Field-Emitter Arrays
(Vanderbilt University. Dept. of Physics and Astronomy, 2009-04-20)
A retarding mesh analyzer was used to measure the electron energy spectrum field emitted from a single tip of a Diamond Field Emitter Array. The emission was dominated by adsorbed gas
atoms and molecules on the surface ...
Multipole mixing ratios of transitions out of high spin gamma vibrational states in neutron rich Mo, Ru isotopes
(Vanderbilt University. Dept. of Physics and Astronomy, 2010-04-27)
Current models of nuclear structure describe nuclear states in terms of
collective vibrations and rotations of a ground state. - One such quadrupole
vibrational band is the gamma-band formed by vibrations of the short ...
Dark radiation from particle decays during big bang nucleosynthesis
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)
Cosmic microwave background (CMB) observations suggest the possibility of an extra dark
radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more
ambiguous. Dark radiation from a decaying ...
