Development of an 11-channel multi wavelength imaging diagnostic for divertor plasmas in MAST Upgrade

Basil Duval, Yanis Andrebe, Artur Perek, Wouter Vijvers

Divertor detachment and alternative divertor magnetic geometries are predicted to be promising approaches to handle the power exhaust of future fusion devices. In order to understand the detachment process caused by volumetric losses in alternative diverto ...

Oxidative Fluorination of Cyclopropylamides through Organic Photoredox Catalysis

Jérôme Waser, Mingming Wang

We report an oxidative ring-opening strategy to transform cyclopropylamides and cyclobutylamides into fluorinated imines. The imines can be isolated in their more stable hemiaminal form, with the fluorine atom installed selectively at the gamma or delta po ...

Method for labeling products with a transparent photoluminescent label, and transparent photoluminescent label

Nicolas Grandjean

A method for marking a product (1) with a photoluminescent mark, said mark comprising a photoluminescent portion (10) which is transparent under normal light conditions and revealed by photoluminescence under UV illumination, said mark further comprising a ...

Magic Prints: Image-Changing Prints Observed under Visible and 365 nm UV Light

Petar Pjanic, Marjan Shahpaski

In this paper we propose a novel layered-printing method consisting of superposed visible cmy and invisible fluorescent ultraviolet (UV) rgb inks. Our approach can be used to generate a variety of visual color-alteration effects such as revealing two compl ...

Effects of InAlN underlayer on deep traps detected in near-UV InGaN/GaN single quantum well light-emitting diodes

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Mauro Mosca, Camille Haller

Two types of near-UV light-emitting diodes (LEDs) with an InGaN/GaN single quantum well (QW) differing only in the presence or absence of an underlayer (UL) consisting of an InAlN/GaN superlattice (SL) were examined. The InAlN-based ULs were previously sho ...

Bis-Sulfone- and Bis-Sulfoxide-Spirobifluorenes: Polar Acceptor Hosts with Tunable Solubilities for Blue-Phosphorescent Light-Emitting Devices

Mohammad Khaja Nazeeruddin

Bis-sulfone- and bis-sulfoxide-spirobifluorenes are a promising class of high-triplet-energy electron-acceptor hosts for blue phosphorescent light-emitting devices. The molecular design and synthetic route are simple and facilitate tailoring of the solubil ...

Photochromic Torsional Switch (PTS): a Light-Driven Actuator for the Dynamic Tuning of π-Conjugation Extension

Pascal Miéville, Riccardo Petraglia, Emilie Baudat, Giuseppe Sforazzini, Adrien Georges Nicolai, Adam Antoni Sobczuk, Luca Cervini

Here we present a molecular architecture that can reversibly change the geometric conformation of its π-system backbone via irradiation with two different wavelengths. The proposed ‘molecular actuator’ consists of a photoswitchable azobenzene orthogonally ...
