Shining the light to terahertz spectroscopy of nL-volume biological samples

Sergey I. Mitryukovskiy, Melanie Lavancier, Flavie Braud, Goedele Roos, Theo Hannotte, Emmanuel Dubois, Jean-Francois Lampin, Romain Peretti

We present a technique allowing the confinement of a broadband terahertz pulse to a few-nL volume. The method is approved in terahertz time-domain spectroscopy study of biological samples and further perspectives are discussed.

Room-Temperature Electron Transport in Self-Assembled Sheets of PbSe Nanocrystals with a Honeycomb Nanogeometry

Maryam Alimoradi Jazi, Aditya Kulkarni, Sophia Buhbut Sinai, Joep Peters, Eva Geschiere, Michele Failla, Christophe Delerue, Arjan Houtepen, Laurens Siebbeles, Daniel Vanmaekelbergh

ABSTRACT: It has been shown recently that atomically coherent superstructures of a nanocrystal monolayer in thickness can be prepared by self-assembly of monodisperse PbSe nanocrystals, followed by oriented attachment. Superstructures with a honeycomb nanogeometry are of special interest, as theory...

Design, fabrication, and characterization of TIP-enhanced Raman spectroscopy probes based on metallic nano-antennas, Conception, fabrication et caractérisation de sondes de spectroscopie raman à exaltation de pointe à base de nano-antennes métalliques

Damien Eschimese

Since the start of the 2000s the evolution of tip-enhanced Raman spectroscopy (TERS) has enabled the simultaneous measurement of localized structural, molecular, and physicochemical properties. TERS technology combines scanning probe microscopy -- atomic force microscopy (AFM) -- with near field..., Depuis les années 2000, le développement de la spectroscopie Raman à exaltation de pointe (TERS) a permis l’accès de manière extrêmement localisée aux propriétés structurales et moléculaires à la surface de la matière et à des analyses physico-chimiques combinées. La technologie TERS associe les...

Textile split ring resonator antenna integrated by embroidery

Jianping Hao, A. Leblanc, Ludovic Burgnies, Amine-Rami Djouadi, Cédric Cochrane, François Rault, Vladan Koncar, Eric Lheurette

A split ring resonator (SRR) antenna integrated in textile by embroidery is reported. The antenna was designed and produced by targeting two goals. First, a size reduction of the antenna was achieved by means of an SRR. Secondly, the connection loss was reduced by using a copper wire dipole fixed...

Mesoscale pore structure of a high‐performance concrete by coupling focused ion beam/scanning electron microscopy and small angle X‐ray scattering

Sébastien Brisard, Catherine Davy, Laurent Michot, David Troadec, Pierre Levitz

This contribution couples (a) Small angle X‐ray scattering (SAXS) experiments of a high‐performance concrete (HPC) at the millimetric scale, and (b) Focused ion beam/scanning electron microscopy (FIB/SEM) of the cement paste of the HPC, with 10‐20 nm voxel size. The aim is to improve the...

Kalman Filter-Based Channel Estimation for Mobile-to-Mobile and Relay Networks

Ali Houssam El Husseini, Laurent Ros, Eric Pierre Simon

This paper deals with channel estimation in mobile-to-mobile communications, possibly including amplify and forward mobile relays, assuming a two-dimensional scattering environment. A second-order autoregressive (AR(2)) model with the Kalman filter is used to estimate the channel gain of the global...

Efficient Equalization for FBMC-OQAM Under Doubly Selective Channel Estimation Errors

Michel Saideh, Iyad Dayoub, Marion Berbineau

The FBMC-OQAM waveform recently has received a lot of interest due to its outstanding spectral characteristics. However, that comes with the cost of a new built-in interference introduced between its subcarriers which triggered the need for new transceiver techniques. In this letter, we propose an...

Two-stages based facial demographic attributes combination for age estimation

Mohammed-En-Nadhir Zighem, Abdelkrim Ouafi, Athmane Zitouni, Yassine Ruichek, Abdelmalik Taleb-Ahmed

Automatic age estimation from face images is a topic of growing interest nowadays, because of its great value in various applications. The main challenge in automatic facial age estimation task comes from the large intra-class facial appearance variations due to both gender and race attributes. To...
