Evaluation of an antenna selection strategy for reduced massive MIMO complexity

Frédéric Challita, M. Lienard, Davy Gaillot, Jose-Maria Molina-Garcia-Pardo

Massive Multiple-Input Multiple-Output (MIMO) is emerging as one promising technology for the fifth generation (5G), but the hardware and software complexity arising from the sheer number of transmitting elements is a bottleneck. Antenna selection strategies have been reported as an appealing…

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…

Sputtered LiNi0.5Mn1.5O4 Thin Films for Lithium-Ion Microbatteries

M. Hallot, Pascal Roussel, C. Lethien

To power miniaturized and smart electronic devices, lithium-ion microbatteries with high energy densities remain the most attractive solution. The Ni-substituted LiMn2O4 spinel material seems to be the most promising high-performance electrodes to significantly enhance the energy density of Li-ion…

[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…

Atomic Layer Deposition of a Nanometer-Thick Li₃PO₄ Protective Layer on LiNi_0.5Mn_1.5O₄ Films: Dream or Reality for Long-Term Cycling?

Maxime Hallot, Borja Caja-Munoz, Clement Leviel, Oleg Lebedev, Richard Retoux, José Avila, Pascal Roussel, Maria Carmen Asensio, Christophe Lethien

LiNi0.5Mn1.5O4 (LNMO) is a promising 5V-class electrode for Li-ion batteries but suffers from manganese dissolution and electrolyte decomposition owing to the high working potential. An attractive solution to stabilize the surface chemistry consists in mastering the interface between the LNMO…
