Analyzing cell–cell interaction is essential to investigate how immune cells function. Elegant designs have been demonstrated to study lymphocytes and their interaction partners. However, these devices have been targeting cells of similar dimensions. T lymphocytes are smaller, more deformable, and...

Optomechanical Hot-Spots in Metallic Nanorod–Polymer Nanocomposites

Thomas Vasileiadis, Adnane Noual, Yuchen Wang, Bartlomiej Graczykowski, Bahram Djafari-Rouhani, Shu Yang, George Fytas

Plasmonic coupling between adjacent metallic nanoparticles can be exploited for acousto-plasmonics, single-molecule sensing, and photochemistry. Light absorption or electron probes can be used to study plasmons and their interactions, but their use is challenging for disordered systems and colloids...

Molecular beam epitaxial growth of 2D-boron nitride on Ni substrates

Jawad Hadid, Ivy Colambo, Jose Avila, Aexandre Plaud, Christophe Boyaval, D. Deresmes, Nicolas Nuns, Pavel Dudin, Annick Loiseau, Julien Barjon, Xavier Wallart, Dominique Vignaud

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. Based on spatially resolved photoemission spectroscopy and on the detection of the π plasmon peak, we discuss the origin of...

Electrocatalytic hydrogen generation using tripod containing pyrazolylborate-based copper(II), nickel(II), and iron(III) complexes loaded on a glassy carbon electrode

Mohamed Ibrahim, G. Mersal, Ahmed Fallatah, Khaled Althubeiti, Hamdy El-Sheshtawy, Manal Abou Taleb, Manash Das, Rabah Boukherroub, Mohamed Attia, Mohammed Amin

Three transition metal complexes (MC) namely, [Tp(MeMe)CuCl(H2O)] (CuC), [Tp(MeMe)NiCl] (NiC), and [Tp(MeMe)FeCl(2)(H2O)] (FeC) {Tp(MeMe) = tris(3,5-dimethylpyrazolypborate) were synthesized and structurally characterized. The three complexes CuC, NiC, and FeC-modified glassy carbon (GC) were...

Physical layer enhancement for next-generation railway communication systems

Qianrui Li, Jean-Christophe Sibel, Marion Berbineau, Iyad Dayoub, François Gallée, Herve Bonneville

This paper presents an overview of the challenges and state-of-the-art physical layer enhancement designs for next-generation railway communication, also known as high-speed train (HST) communication. The physical layer design for the HST should adapt from its counterpart in the general-purpose...

Comparison of Brillouin Light Scattering and Density of States in a Supported Layer: Analytical and Experimental Study

Ossama El Abouti, John Cuffe, El Houssaine El Boudouti, Clivia Sotomayor Torres, Emigdio Chavez-Angel, Bahram Djafari-Rouhani, Francesc Alzina

We provide a detailed analytical calculation of the Brillouin light scattering (BLS) intensity of a layer on a substrate, taking into account both photoelastic and moving boundary (ripple effect) mechanisms, and give a comparison between BLS intensity and density of states (DOS) to determine the...
