Elucidating the mechanism of the considerable mechanical stiffening of DNA induced by the couple Zn2+/Calix[4]arene-1,3-O-diphosphorous acid

Yannick Tauran, Mehmet Tarhan, Laurent Mollet, Jean Baptiste Gerves, Momoko Kumemura, Laurent Jalabert, Nicolas Lafitte, Ikjoo Byun, Beomjoon Kim, Hiroyuki Fujita, Dominique Collard, Florent Perret, Mickael Desbrosses, Didier Léonard, Christelle Goutaudier, Anthony Coleman

The couple Calix[4]arene-1,3-O-diphosphorous acid (C4diP) and zinc ions (Zn 2+) acts as a synergistic DNA binder. Silicon NanoTweezer (SNT) measurements show an increase in the mechanical stiffness of DNA bundles by a factor of >150, at Zn 2+ to C4diP ratios above 8, as compared to Zinc alone...

Electronic contribution in heat transfer at metal-semiconductor and metal silicide-semiconductor interfaces

Georges Hamaoui, Nicolas Horny, Zilong Hua, Tianqi Zhu, J.F. Robillard, Austin Fleming, Heng Ban, Mihai Chirtoc

This work presents a direct measurement of the Kapitza thermal boundary resistance Rth, between platinum-silicon and platinum silicide-silicon interfaces. Experimental measurements were made using a frequency domain photothermal radiometry set up at room temperature. The studied samples consist of...

Evolution of LSPR of gold nanowire chain embedded in dielectric multilayers

Zakariae Oumekloul, S. Lahlali, A. Mir, Abdellatif Akjouj

The objective of this paper is to improve the sensitivity and the performance of nano-sensors by using the simulation, which was done by finite element method in 2D plasmonic nanostructures. Meanwhile, the effects of geometric parameters of a hexagonal gold nanostructure, and the influence of two...

Performance analysis of AO‐OFDM‐CDMA with advanced 2D‐hybrid coding for amplifier‐free LR‐PONs

Hichem Mrabet, Sofien Mhatli, Iyad Dayoub, Elias Giacoumidis

All-optical orthogonal frequency division multiplexing (AO-OFDM) and optical code-division multiple-access system (OCDMA) are combined in the first analytical model, which considers subcarrier hopping by means of advanced two-dimensional (2D) hybrid-coded (2D-HC) signature. The model incorporates...

Robustness of elastic properties in polymer nanocomposite films examined over the full volume fraction range

Elena Alonso-Redondo, Laurent Belliard, K. Rolle, Bartlomiej Graczykowski, Wolfgang Tremel, Bahram Djafari-Rouhani, George Fytas

Polymers with nanoparticle inclusions are attractive materials because physical properties can be tuned by varying size and volume fraction range. However, elastic behavior can degrade at higher inclusion fractions when particle-particle contacts become important, and sophisticated measurement...

On the origins of transport inefficiencies in mesoscopic networks

Sébastien Toussaint, Frederico Martins, Sebastien Faniel, Marco Pala, L. Desplanque, Xavier Wallart, Hermann Sellier, Serge Huant, Vincent Bayot, Benoit Hackens

A counter-intuitive behavior analogous to the Braess paradox is encountered in a two-terminal mesoscopic network patterned in a two-dimensional electron system (2DES). Decreasing locally the electron density of one channel of the network paradoxically leads to an increased network electrical...
