Resonant Absorption in GaAs-Based Nanowires by Means of Photo-Acoustic Spectroscopy
Semiconductor nanowires made of high refractive index materials can couple the incoming light to specific waveguide modes that offer resonant absorption enhancement under the bandgap wavelength, essential for light harvesting, ...
Directions in QPPR development to complement the predictive models used in risk assessment of nanomaterials
There is an increasing need for predictive risk assessment of nanomaterials (NMs) using methods that are rapid, accurate and resource efficient. To fulfill this need, the development and use of Quantitative Property Property ...
Standoff alpha radiation detection for hot cell imaging and crime scene investigation
This paper presents the remote detection of alpha contamination in a nuclear facility. Alpha-active material in a shielded nuclear radiation containment chamber has been localized by optical means. Furthermore, sources of ...
Spin filtering in silicene by edges and chemically or electrically induced interfaces
Silicene is a graphene-like material with relatively strong spin-orbit coupling exhibiting gapless topologically protected edge states. In addition, it has a buckled structure, and hence, it stands as a feasible candidate ...
Metal/Polymer Back Reflectors with Diffraction Gratings for Light Trapping in III-V Solar Cells
We report on the fabrication, characterization and simulation of diffraction gratings for back contact reflectors in III-V solar cells. The gratings are designed for thin-film solar cells incorporating absorbers with bandgap ...
Comparison of ‘shallow’ and ‘deep’ junction architectures for MBE-grown InAs/GaAs quantum dot solar cells
We report on the fabrication of InAs/GaAs quantum dot solar cells with high open circuit voltage by molecular beam epitaxy. ‘Shallow’ and ‘deep’ junction architectures were compared. The highest open circuit voltage of ...
Alpha radiation induced luminescence in solar blind spectral region
(OSA - The Optical Society, 2018)
Intense luminescence in the solar blind spectral region is produced by modifying the gas atmosphere around an alpha emitter. This enables standoffdetection of alpha radiation under daylight conditions.
How Cardiolipin Peroxidation Alters the Properties of the Inner Mitochondrial Membrane?
Cardiolipins have multiple vital functions within biological cell membranes, most notably in the energy metabolism associated with the inner mitochondrial membrane. Considering their essential role, peroxidation of ...
The characterization of surgical smoke from various tissues and its implications for occupational safety
Electrosurgery produces surgical smoke. Different tissues produce different quantities and types of smoke, so we studied the particle characteristics of this surgical smoke in order to analyze the implications for the ...
Photo-Acoustic Spectroscopy Reveals Extrinsic Optical Chirality in GaAs-Based Nanowires Partially Covered with Gold
We report on the extrinsic chirality behavior of GaAs-based NWs asymmetrically hybridized with Au. The samples are fabricated by a recently developed, lithography-free self-organized GaAs growth, with the addition of AlGaAs ...
