Probing the Electrochemical Li Insertion–Extraction Mechanism in Sputtered LiNi0.5Mn1.5O4 Thin Film Cathode for Li‐Ion Microbattery

Ankush Bhatia, Clement Leviel, Maxime Hallot, Jean Pierre Pereira-Ramos, Christophe Lethien, Pascal Roussel, Rita Baddour-Hadjean

Due to its great theoretical capacity (147 mAh g−1) and high operating potential (4.7 V vs Li+/Li), Co-free spinel LiNi0.5Mn1.5O4 (LNMO) is one of the most promising thin film cathodes allowing designing Li-ion micro-batteries with a high specific energy. In this work, the Li extraction–insertion…

Understanding the Effect of Ni-Substitution on the Oxygen Evolution Reaction of (100) IrO 2 Surfaces

Gaëtan Buvat, Mohammad Eslamibidgoli, Tianjun Zhang, Sagar Prabhudev, Azza Hadj Youssef, Andreas Ruediger, Sébastien Garbarino, Gianluigi Botton, Peng Zhang, Michael Eikerling, Daniel Guay

The electrolysis process of water is impeded by the slow kinetics of the oxygen evolution reaction (OER). While iridium oxide (IrO2) is considered one of the most efficient metal catalysts for the OER, the adsorption of the OER intermediates at the IrO2 surface is not optimal, the *OH intermediate…

Improvement of emotion recognition from facial images using deep learning and early stopping cross validation

Mohamed Bentoumi, Mohamed Daoud, Mohamed Benaouali, Abdelmalik Taleb-Ahmed

Inthis paper, we present a new approach for emotion recognition from facial images. The proposed method is based on the association of a pretrained convolutional neural network (CNN) model (VGG16, ResNet50) with a multilayer perceptron (MLP) classifier. The pretrained CNN model is used as a feature…

Statistical mechanics of rate-independent stick-slip on a corrugated surface composed of parabolic wells

Stefano Giordano

The stick-slip phenomenon, at the basis of friction, is crucial for several applications ranging from nanotechnology and biophysics to mechanics and geology. Deep understanding of friction mechanisms and, in particular, the methodologies for its reduction must be sought in its nanoscopic nature,…

Sustainability in (bio-)analytical chemistry [Editorial]

Antje Baeumner, Günter Gauglitz, Luigi Mondello, María Cruz Moreno Bondi, Sabine Szunerits, Qiuquan Wang, Stephen Wise, Adam Woolley

We all live on this amazing planet, which, with available sunlight and abundant resources, offers more than enough to maintain life and livelihood. Nevertheless, how we continue to consume what the Earth provides will decide for what duration humanity will still be able to meet these ongoing needs…

Friedrich-Wintgen bound states in the continuum and induced resonances in a loop laterally coupled to a waveguide

Madiha Amrani, Soufyane Khattou, El Houssaine El Boudouti, Abdelkrim Talbi, Abdellatif Akjouj, Leonard Dobrzynski, Bahram Djafari-Rouhani

The concept of bound states in the continuum (BICs) in a simple cavity attracts much interest in recent works in wave physics. The BICs are perfectly confined modes with an infinite lifetime that reside inside the continuous spectrum of radiative modes, but they remain totally decoupled from it.…

Distinguishing cellular from abiotic spheroidal microstructures in the ca. 3.4 Ga Strelley Pool Formation

Maxime Coutant, Kevin Lepot, Alexandre Fadel, Ahmed Addad, Élodie Richard, David Troadec, Sandra Ventalon, Kenichiro Sugitani, Emmanuelle Javaux

The morphogenesis of most carbonaceous microstructures that resemble microfossils in Archean (4–2.5 Ga old) rocks remains debated. The associated carbonaceous matter may even—in some cases—derive from abiotic organic molecules. Mineral growths associated with organic matter migration may mimic…
