Flow injection enzymatic biosensor for aldehydes based on a Meldola Blue-Ni complex electrochemical mediator

Ana Maria Titoiu, Georgiana Necula-Petrareanu, Diana Visinescu, Valentina Dinca, Anca Bonciu, Cristian Mihailescu, Cristina Purcarea, Rabah Boukherroub, Sabine Szunerits, Alina Vasilescu

Carbon nanofibers (CNF) are efficient electrode modifiers in electrochemical biosensors that enhance the electrochemical active area, induce electrocatalytic effect toward the oxidation of the enzymatic cofactor nicotinamide adenine dinucleotide (reduced form, NADH), and enable the quantitative…

Deep CNN-based Pedestrian Detection for Intelligent Infrastructure

Bilel Tarchoun, Imen Jegham, Anouar Ben Khalifa, Ihsen Alouani, Mohamed Ali Mahjoub

Autonomous driving systems and driver assistance systems are becoming the center of attention in transport technology. Given its safety criticality, pedestrian detection is a highly important task. Transport oriented intelligent systems use embedded sensors for the detection task. However, vehicle…

Long-range nonspreading propagation of sound beam through periodic layered structure

Yurii Zubov, Bahram Djafari-Rouhani, Yuqi Jin, Mathew Sofield, Ezekiel Walker, Arup Neogi, Arkadii Krokhin

Linear spreading of a wave packet or a Gaussian beam is a fundamental effect known in evolution of quantum state and propagation of optical/acoustic beams. The rate of spreading is determined by the diffraction coefficientDwhich is proportional to the curvature of the isofrequency surface. Here, we…

Enzymatic depolymerization of industrial lignins by laccase-mediator systems in 1,4-dioxane/water

Justine Dillies, Céline Vivien, Mickael Chevalier, Alexandre Rulence, Gabrielle Châtaigné, Christophe Flahaut, Vincent Senez, Renato Froidevaux

Lignin is the second most abundant polymer after cellulose in lignocellulosic biomass. Its aromatic composition and recalcitrant nature make its valorization a major challenge for obtaining low molecular weight aromatics compounds with high value-added from the enzymatic depolymerization of…

A Comparative Performance Evaluation of 2D Nanomaterials for Applications in Plasmonic Biosensing

Kang Lx, Das Cm, Liu D, Chen Mw, P. Coquet, Hong G, Yong Kt

Plasmonic sensing relies on the interaction between the electromagnetic light wave and free electrons that reside at the interface of two materials, one of them being a metal. Surface plasmon resonance (SPR)‐based biosensing has distinct advantages of providing real‐time and label‐free detection…

Female role models in analytical chemistry: then, now, and in the future

Antje J. Baeumner, Hua Cui, Maria Cruz Moreno Bondi, Sabine Szunerits

“Who were your role models?” is a question we get asked seemingly at all relevant career stages of our scientific lives. Concerning women in chemistry, this question is often asked with more precision inquiring about our female role models in chemistry. This question is answered quickly—no need to…

Topological states in twisted pillared phononic plates

Yabin Jin, Wan Wang, Zhihui Wen, Daniel Torrent, Bahram Djafari-Rouhani

In recent years, the advances in topological insulator in the fields of condensed matter have been extended to classical wave systems such as acoustic and elastic waves. However, the quantitative robustness study of topological states which is indispensable in practical realization is rarely…

Rate-dependent force–extension models for single-molecule force spectroscopy experiments

Manon Benedito, Fabio Manca, Pier Luca Palla, Stefano Giordano

Single-molecule force spectroscopy (SMFS) techniques allow for the measurements of several static and dynamic features of macromolecules of biological origin. In particular, the atomic force microscopy (AFM), used with a variable pulling rate, provides valuable information on the folding/unfolding…

PEDOT:PSS-based micromuscles and microsensors fully integrated in flexible chips

Kätlin Rohtlaid, Lauréline Seurre, Giao T M Nguyen, Garrett Curley, Caroline Soyer, Sébastien Grondel, Frederic Vidal, Cedric Plesse, Eric Cattan

The demand for polymer-based soft micro-electro-mechanical systems (MEMS) is growing due to the substantial increase of flexible and wearable electronic devices. In this context, electronically conducting polymers (ECPs) fulfil the requirements for soft MEMS by offering the possibility of actuation…

Beyond linear coupling in microwave optomechanics

D. Cattiaux, Xin Zhou, S. Kumar, I. Golokolenov, R. R Gazizulin, A. Luck, L Mercier de Lépinay, M. Sillanpää, A. D Armour, A. Fefferman, E. Collin

We explore the nonlinear dynamics of a cavity optomechanical system. Our realization consisting of a drumhead nano-electro-mechanical resonator (NEMS) coupled to a microwave cavity, allows for a nearly ideal platform to study the nonlinearities arising purely due to radiation-pressure physics.…
