Major Improvement in the Cycling Ability of Pseudocapacitive Vanadium Nitride Films for Micro‐Supercapacitor

Aiman Jrondi, Gaëtan Buvat, Francisco de La Pena, Maya Marinova, Marielle Huvé, Thierry Brousse, Pascal Roussel, Christophe Lethien

Vanadium nitride film made using a thin film deposition technique is a promising electrode material for micro-supercapacitor applications owing to its high electrical conductivity and high volumetric and surface capacitance values in aqueous electrolyte. Nevertheless, the cycling stability has to…

Assessment of Large Critical Electric Field in Ultra-wide Bandgap p- type Spinel ZnGa2O4

Zeyu Chi, Tamar Tchelidze, Corinne Sartel, Tsotne Gamsakhurdashvili, Ismail Madaci, Hayate Yamano, Vincent Sallet, Yves Dumont, Amador Pérez-Tomas, Farid Medjdoub, Ekaterine Chikoidze

The spinel Zinc Gallate ZnGa2O4 stands out among the emerging ultra-wide bandgap (~5eV) semiconductors as the ternary complex oxide with the widest gap where bipolar conductivity (electrons and holes) has been demonstrated. For power and energy electronic applications, a fundamental property of the…

Two-photon responsive fluorophore-porphyrin biodegradable PMO nanoparticles for FRET-enhanced PDT and antibiotic encapsulation

Nicolas Bondon, Clement Charlot, Alexandre Barras, Christophe Nguyen, Lamiaa Ali, Denis Durand, Sabine Szunerits, Rabah Boukherroub, Nicolas Richy, Olivier Mongin, Nadir Bettache, Magali Gary-Bobo, Jean-Olivier Durand, Clarence Charnay

Herein, we report the successful multi-step syntheses of new two-photon responsive octupolar-shaped fluorophores with pendant propanol groups, abbreviated as F1 and F2. Mass spectrometry 1H NMR measurements confirmed they were pure isolated. This type compounds has already proven good…

Bio-inspired non self-similar hierarchical elastic metamaterials

M. Mazzotti, A. Foehr, O.R. Bilal, A. Bergamini, F. Bosia, C. Daraio, N.M. Pugno, M. Miniaci

Hierarchy provides unique opportunities for the design of advanced materials with superior properties that arise from architecture, rather than from constitutive material response. Contrary to the quasi-static regime, where the potential of hierarchy has been largely explored, its role in vibration…

Temperature dependent model for the quasi-static stick–slip process on a soft substrate

Stefano Giordano

The classical Prandtl–Tomlinson model is the most famous and efficient method to describe the stick–slip phenomenon and the resulting friction between a slider and a corrugated substrate. It is widely used in all studies of frictional physics and notably in nanotribology. However, it considers a…

Straightforward bias- and frequency-dependent small-signal model extraction for single-layer graphene FETs

Nikolaos Mavredakis, Anibal Pacheco-Sanchez, Wei Wei, Emiliano Pallecchi, Henri Happy, David Jiménez

We propose an explicit small-signal graphene field-effect transistor (GFET) parameter extraction procedure based on a charge-based quasi-static model. The dependence of the small-signal parameters on both gate voltage and frequency is precisely validated by high-frequency (up to 18 GHz) on-wafer…

Thermal effects on fracture and the brittle-to-ductile transition

Andrea Cannizzo, Stefano Giordano

The fracture behavior of brittle and ductile materials can be strongly influenced by thermal fluctuations, especially in micro-and nano-devices as well as in rubberlike and biological materials. However, temperature effects, in particular on the brittle-to-ductile transition, still require a deeper…
