Molecular Design Principles for Near-Infrared Absorbing and Emitting Indolizine Dyes

Mohammad Khaja Nazeeruddin, Aswani Yella, Aron Joel Huckaba

Desirable components for dye-sensitzed solar cell ( DSC) sensitizers and fluorescent imaging dyes include strong donating building blocks coupled with well-balanced acceptor functionalities for absorption beyond the visible range. We have evaluated the eff ...

How does Tetraphenylethylene Relax from its Excited States?

Antonio Prlj

Tetraphenylethylene is a prototypical example of a molecule displaying aggregation-induced emission. Despite many studies on the optical properties of TPE and its derivatives, the origin of the non-emissive behavior in the gas phase or in dilute solutions ...

Large-Area Low-Cost Plasmonic Perfect Absorber Chemical Sensor Fabricated by Laser Interference Lithography

Andreas Tittl

We employ laser interference lithography as a reliable and low-cost fabrication method to create nanowire and nanosquare arrays in photopolymers for manufacturing plasmonic perfect absorber sensors over homogeneous areas as large as 5.7 cm(2). Subsequently ...

Orientation Dependence of Plasmonically Enhanced Spontaneous Emission

Olivier Martin

We computationally explore how the orientation of dipolar emitters placed near plasmonic nanostructures affects their radiative enhancement and spontaneous emission rate. We demonstrate that the expressions for these quantities show a subtle dependence on ...

Operational regimes in a closed loop pulsating heat pipe

John Richard Thome, Navid Borhani, Giulia Spinato

Synchronized thermal and visual investigation was carried out on a single-turn channel CLPHP using R245fa as the worldng fluid. The tests were carried out at filling ratios from 10 to 90% and heat inputs from 2 to 60 W for vertical and inclined orientation ...

Three-dimensional concentration of light in deeply sub-wavelength, laterally tapered gap-plasmon nanocavities

Giulia Tagliabue, Dimos Poulikakos

Gap-plasmons (GP) in metal-insulator-metal (MIM) structures have shown exceptional performance in guiding and concentrating light within deep subwavelength layers. Reported designs to date exploit tapered thicknesses of the insulating layer in order to con ...

A novel carbon coating technique for foil bolometers

Basil Duval, Benoît Labit, Umar Sheikh, Federico Nespoli

Naked foil bolometers can reflect a significant fraction of incident energy and therefore cannot be used for absolute measurements. This paper outlines a novel coating approach to address this problem by blackening the surface of gold foil bolometers using ...

Rapid-Response Low Infrared Emission Broadband Ultrathin Plasmonic Light Absorber

Giulia Tagliabue, Dimos Poulikakos

Plasmonic nanostructures can significantly advance broadband visible-light absorption, with absorber thicknesses in the sub-wavelength regime, much thinner than conventional broadband coatings. Such absorbers have inherently very small heat capacity, hence ...

Pore structure evolution of compacted granular bentonite during wetting and drying cycles

Lyesse Laloui, Alessio Ferrari, Ali Seiphoori

Deep geological repositories are considered as suitable solutions for the disposal of high level nuclear wastes. In several repository concepts (e.g. in Spain and Switzerland), bentonites are selected as the main component of the engineered barrier to be p ...
