Curcuminoid Derivatives with a Donor‐Acceptor‐Donor Architecture: an Outstanding Platform for Highly‐Efficient Near‐Infrared Electroluminescence and Amplified Spontaneous Emission

open access: yesAdvanced Optical Materials, EarlyView.
Curcuminoid boron difluoride dyes containing triphenylamine units are prepared and their photophysical and electrochemical properties are investigated. These new light‐emitting dyes are used in organic light‐emitting diodes (OLEDs) emitting at 800 nm with 1% external quantum efficiency, and show low threshold amplified spontaneous emission in thin ...

Bubble Printing of Anisotropic Clay Nanotubes

open access: yesAdvanced Optical Materials, EarlyView.
Bubble printing patterns of lyotropic liquid crystal nanotubes form toroidal or linear patterns depending on laser movement and colloidal stability. Long nanotubes create radial filament bundles, while poor electrostatic repulsion hinders deposition.

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

open access: yesAdvanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

LE PARIS DE BALZAC : ÉCRITURE DU MYTHE OU MYTHE DE L’ÉCRITURE ? [PDF]

open access: yesStudii si Cercetari Filologice: Seria Limbi Romanice, 2013
On considère que Balzac a élaboré un imaginaire mythique de la ville, une image métaphorique et allégorique de la métropole moderne en devenir. La critique en a élaboré différentes conceptions, du mythe du héros moderne à celui de la lisibilité de la ...

Graphene as Infrared and Electron Transparent Electrode Applied to the Design of Narrow Bandgap Nanocrystal‐Based Photodiode

open access: yesAdvanced Optical Materials, EarlyView.
The article explores the need for transparent conductive electrode in the context of nanocrystal based infrared photodetectors beyond traditional transparent conductive oxide and metallic grids. Use of such sensor for imaging where the diode is deposited on a read‐out integrated circuit raised the need for top transparent electrode.
