Electronic properties of atomically coherent square PbSe nanocrystal superlattice resolved by Scanning Tunneling Spectroscopy

Pierre Capiod, Maaike van Der Sluijs, Jeroen de Boer, Christophe Delerue, Ingmar Swart, Daniel Vanmaekelbergh

Rock-salt lead selenide nanocrystals can be used as building blocks for large scale square superlattices via two-dimensional assembly of nanocrystals at a liquid-air interface followed by oriented attachment. Here we report Scanning Tunneling Spectroscopy (STS) measurements of the local density of…

Freehand system for antenna diagnosis based on amplitude-only data

Guillermo Alvarez-Narciandi, Jaime Laviada, Yuri Alvarez-Lopez, Guillaume Ducournau, Cyril Luxey, Cybelle Belem-Gonçalves, Frédéric Gianesello, Nour Nachabe, Carlos del Rio, Fernando Las-Heras

This article presents a portable system for freehand antenna diagnosis and characterization based on amplitude-only data. The amplitude-only samples are acquired by moving a handheld probe, which is tracked by a motion capture system, in front of the antenna under test (AUT) aperture. The acquired…

Enhanced visible light-triggered antibacterial activity of carbon quantum dots/polyurethane nanocomposites by gamma rays induced pre-treatment

Milica Budimir, Zoran Markovic, Jan Vajdak, Svetlana Jovanović, Pavel Kubát, Petr Humpoliček, Matej Mičušík, Martin Danko, Alexandre Barras, Dušan Milivojević, Zdenko Špitalský, Rabah Boukherroub, Biljana Todorović Marković

Persistent microbial contamination of medical implant surfaces is becoming a serious threat to public health. This is principally due to antibiotic-resistant bacterial strains and the formation of bacterial biofilms. The development of novel antibacterial materials that will effectively fight both…

Surface micromachining of chip-edge silicon microcantilevers using xenon difluoride etching of silicon-on-insulator

Thomas Lerond, Dmitri Yarekha, Vanessa Avramovic, Thierry Melin, S. Arscott

We demonstrate a straightforward surface micromachining process for the rapid prototyping of thin 'chip-edge' silicon microcantilevers protruding from the edge of a silicon-on-insulator chip. The process uses a single photolithographic mask-with xenon difluoride used to both pattern the…

Thermal performance of self-rewetting gold nanofluids: application to two-phase heat transfer devices

Ibrahim Zaaroura, Souad Harmand, Julien Carlier, Malika Toubal, Aurélie Fasquelle, Bertrand Nongaillard

This paper presents an experimental analysis of the phenomenon of phase change inside a porous medium using different types of working fluids. It represents the impact of these fluids on improving the characteristics of heat and mass transfer in a Capillary Heat Pipe (CHP). In this study, gold…

Modeling and Prediction of the Dynamic Viscosity of Nanofluids by a Homogenization Method

Ibrahim Zaaroura, Hilal Reda, Fabrice Lefebvre, Julien Carlier, Malika Toubal, Souad Harmand, Bertrand Nongaillard, Hassan Lakiss

Nanofluids are an innovative technology that can be used to improve the efficiency of heat transfer in systems such as coolers. Thermal system design requires access to all the physical properties of the nanofluids among which viscosity, thermal conductivity, and so on. Viscosity is an important…

[Invited] THz spintronic emitters with magnetoelectric control of the polarization and applications to polarimetry

Nicolas Tiercelin, Geoffrey Lezier, Pierre Koleják, Jean-Francois Lampin, Kamil Postava, Mathias Vanwolleghem

We present a scheme to achieve coherent polarization rotation without multipolar or rotating external magnetic bias nor complex cascaded emitters, by exploiting artificially engineered strong uniaxial anisotropy in intermetallic heterostructures of rare-earth and transition metals. By replacing the…

Genipin-mediated immobilization of glucose oxidase enzyme on carbon felt for use as heterogeneous catalyst in sustainable wastewater treatment

May Kahoush, Nemeshwaree Behary, Jinping Guan, Aurélie Cayla, Brigitte Mutel, Vincent Nierstrasz

Enzyme immobilization is necessary process to improve the bioactivity and stability of the biocatalyst. In this study, glucose oxidase (GOx) enzyme was immobilized on plasma-treated fibrous carbon felt as a textile carrier to produce a heterogeneous catalyst. Genipin, as a naturally occurring…
