Validation of conformal radiotherapy treatments in 3D using polymer gel dosimeters and optical computed tomography
(2008-12-18)Polymer gel dosimeters are a three dimensional (3D) dosimetry system that may be conveniently applied for verifying highly conformal radiation therapies where standard dosimetry techniques are insufficient. Polymer gel ... -
A Vertical Coarse Approach Scanning Tunneling Microscope
(2009-06-25)A Pan-style scanning tunneling microscope (STM), with a vertical coarse approach mechanism, was designed, built and tested. The microscope will be operated in ultra-high vacuum and also at cryogenic temperatures (8 K) ... -
Visualizing the Bipolar Electrochemistry of Electrochemically Doped Luminescent Conjugated Polymers
(American Chemical Society (ACS), 2017-04-20)A micromanipulated vacuum probe station and fluorescence imaging are used to induce and visualize bipolar electrochemical redox reactions in a solid-state polymer light-emitting electrochemical cell (PLEC). The PLEC is a ... -
The Volume of Black Holes
(2012-06-06)The invariant four-volume ($\mathcal V$) of a complete four-dimensional black hole (the volume of the spacetime at and interior to the horizon) diverges. However, if one considers the black hole resulting from the gravitational ... -
Wet-etched phononic crystal waveguiding on GaAs
(IOP Publishing, 2018-01-10)A wet-etched phononic crystal waveguide in GaAs with approximately two micron deep inclusions is studied both numerically and experimentally for controlled surface acoustic wave propagation. Numerically, the phononic crystal ... -
The White Beam Steady-State Diffractometer: A Next Generation Neutron Diffraction Strain Scanner
(2009-04-24)This project proposes a reactor-based instrument, which retains most of the above advantages of spallation source engineering instruments, while maintaining the advantages inherent to steady-state instruments. The main ... -
Wireless Electroluminescence: Polymer Light-Emitting Electrochemical Cells with Inkjet-Printed 1D and 2D Bipolar Electrode Arrays
(American Chemical Society (ACS), 2018-04-26)One-dimensional (1D) and two-dimensional (2D) arrays of conductive microdisks are printed on glass substrates using a silver nanoparticle (Ag-NP)-based ink. Polymer light-emitting electrochemical cells (PLECs) are then ... -
A Zinc(II) Benzamidinate-N-oxide Complex as an Aggregation-Induced Emission Material: toward Solution-Processable White Organic Light-Emitting Devices
(Wiley, 2018-10-11)The synthesis, characterization, photophysical and redox properties of a dinuclear complex Zn2(AMOX)4 (AMOX = 4-bromo N,N’-diphenylbenzamidinate-N-oxide) are highlighted. This compound is a first example of a novel class ...
