Heat treatment of commercial polydimethylsiloxane PDMS precursors: Part II. Thermal properties of carbon-based ceramic nanocomposites

Srisaran Venkatachalam, Stéphane Lenfant, Michael Depriester, Abdelhak Hadj Sahraoui, D. Hourlier

Organosilicon polymer-derived ceramic (PDC) materials have been extensively studied for their various properties such as mechanical, chemical and electrical properties. One of the least explored properties of PDC is their thermal properties, required for designing a heat energy converter. In this…

Channel correlation-based approach for feedback overhead reduction in massive MIMO

Frédéric Challita, Pierre Laly, Marwan Yusuf, Emmeric Tanghe, Wout Joseph, Pierre Degauque, M. Lienard, Davy Gaillot

For frequency-division duplex multiple-input-multiple-output (MIMO) systems, the channel state information at the transmitter is usually obtained by sending pilots or reference signals from all elements of the antenna array. The channel is then estimated by the receiver and communicated back to the…

[Invited] Hydrogels and Other Ionic Conductors in ‘Piezo-Ionic’ Sensors, Actuators and Electrochemical Devices

John D.W. Madden, Yuta Dobashi, Mirza Sarwar, Dickson Yao, Saeedeh Ebrahimi Takalloo, Claire Preston, Tan Ngoc Nguyen, Justin Wyss, Bertille Dupont, Yael Petel, Carl Michal, Cedric Plesse, Giao Tran-Minh Nguyen, Frederic Vidal, Eric Cattan, Sébastien Grondel, David Shepherd, Geoffrey Spinks

Ionic conductors offer exciting device possibilities, particularly with the advent of highly extensible and easily synthesized hydrogels. Following on from recent work on hydrogel “ionic skin”, ‘piezo-ionic’ sensors and ionic artificial muscle, we present example ionic devices, including…

Iuliacumite: A Novel Chemical Short-Range Order in a Two-Dimensional Wurtzite Single Monolayer InAs 1– x Sb x Shell on InAs Nanowires

M. Schnedler, T. Xu, Isabelle Lefebvre, J.-P. Nys, S R Plissard, Maxime Berthe, H. Eisele, R. E Dunin-Borkowski, Ph. Ebert, B. Grandidier

A chemical short range order is found in single monolayer InAs 1-x Sb x shells, which inherit a wurtzite structure from the underlying InAs nanowire, instead of crystallizing in the energetically preferred zincblende structure. The chemical order is characterized by an anti-correlation ordering…

Encapsulation of a TRPM8 Agonist, WS12, in Lipid Nanocapsules Potentiates PC3 Prostate Cancer Cell Migration Inhibition through Channel Activation

G. Grolez, M. Hammadi, Alexandre Barras, D. Gordienko, C. Slomianny, P. Völkel, P. Angrand, M. Pinault, C. Guimaraes, M. Potier-Cartereau, N. Prevarskaya, Rabah Boukherroub, D. Gkika

In prostate carcinogenesis, expression and/or activation of the Transient Receptor Potential Melastatin 8 channel (TRPM8) was shown to block in vitro Prostate Cancer (PCa) cell migration. Because of their localization at the plasma membrane, ion channels, such as TRPM8 and other membrane receptors…

Intrinsic versus shape anisotropy in micro-structured magnetostrictive thin films for magnetic surface acoustic wave sensors

Harshad Mishra, Michel Hehn, Daniel Lacour, Omar Elmazria, Nicolas Tiercelin, Hamid Mjahed, Karine Dumesnil, Sébastien Petit, Vincent Polewczyk, Abdelkrim Talbi, Olivier Bou Matar, Sami Hage-Ali

This work aims at studying the interaction between surface acoustic waves (SAW) and micro-structured magnetostrictive layers under a magnetic field with a perspective to develop magnetic field sensors. The impact of the competition between the strong intrinsic magnetic anisotropy of the magnetic…

Optical external efficiency of terahertz quantum cascade laser based on Čerenkov difference frequency generation

A. Hamadou, Jean-Luc Thobel, S. Lamari

In this paper, we consider terahertz sources based on Čerenkov difference frequency generation in a dual-wavelength mid-infrared quantum cascade laser and calculate analytically the optical external efficiency of the out-going terahertz wave. The mid-infrared pumps operate simultaneously and have a…
