Design of keto-coumarin based photoinitiator for Free Radical Photopolymerization: Towards 3D printing and photocomposites applications

In this article, ten organic dyes based on keto-coumarin (KC) derivatives (MeO-Coum1, MeO-Coum10) have been synthesized and characterized as high performance photoinitiators for the Free Radical Photopolymerization (FRP) of acrylates upon visible…

Naphthalimide-Based Dyes as Photoinitiators under Visible Light Irradiation and their Applications: Photocomposite Synthesis, 3D printing and Polymerization in Water

In this work, six new fluorescent dyes derived from the naphthalimide scaffold (Napht1–Napht6) were synthesized and used as high-performance photoinitiating systems (PISs) in two and three-component systems (combined with iodonium salt (Iod) and/or…

Comparison of magnetic coupling topologies for interleaved multilevel inverters

This paper presents a study and comparison in terms of magnetic circuit sizing for two magnetic coupling topologies for interleaved multilevel inverters: the cyclic cascade and the secondary loop. This comparison includes modeling of both topologies…

A New Arm Voltage Control Scheme for a Single Phase Modular Multilevel Converter

Modular Multilevel Converters (MMCs) are widely used in medium to high voltage/power applications such as in energy transformation and grid connected systems. MMCs benefit from being redundant and allowing transformer-less operations. Unfortunately,…

Mesure de champ magnétique pour détecter le court-circuit dans le convertisseur de puissance

Les capteurs de courant jouent un rôle important en électronique de puissance tant pour la protection des convertisseurs que pour leur contrôle. Ce papier propose une méthode de détection des événements de court-circuit à travers des mesures du…

Evaluating sleep deprivation and time-of-day influences on crash avoidance maneuvers of young motorcyclists using a dynamic simulator

Motorcyclists are particularly at risk of being injured when involved in a road traffic accident. To avoid such crashes, emergency braking and/or swerving maneuvers are frequently performed. The recent development of dynamic motorcycle simulators…
