Soft fault detection and localization in an unshielded twisted pair network using power line communication

Abdelkarim Abdelkarim, Virginie Degardin, Vincent Cocquempot, Mohamed Amine Atoui

Vehicular electrical wires and communication systems can be affected by faults. Depending on their severity, faults can be divided into two families: hard and soft faults. Hard faults indicate open/short circuits that can lead to serious breakdowns because they prevent the flow of energy or…

[1+1] Copper(II) macrocyclic Schiff base complex on rGO as a photocatalyst for reduction of nitroaromatics compounds under visible-light irradiation

Saeed Nasiri Ghalebin, Abolfazl Bezaatpour, Moayad Hossaini Sadr, Mirabdullah Seyed Sadjadi, Mohammad Khodadadi Moghaddam, Sabine Szunerits

In this work, [1 + 1] macrocyclic Copper(II) Schiff base complex ([CuL](NO3)2.H2O) was synthesized and grafted on reduced graphene oxide successfully. The novel prepared sample was characterized by physico-chemical techniques and used as a photocatalyst for the reduction of nitroaromatic compounds…

Conductance switching of azobenzene-based self-assembled monolayers on cobalt probed by UHV conductive-AFM

Louis Thomas, Imane Arbouch, David Guérin, X. Wallart, Colin van Dyck, Thierry Melin, Jérôme Cornil, Dominique Vuillaume, Stéphane Lenfant

We report the formation of self-assembled monolayers of a molecular photoswitch (azobenzene-bithiophene derivative, AzBT) on cobalt via a thiol covalent bond. We study the electrical properties of the molecular junctions formed with the tip of a conductive atomic force microscope under ultra-high…
