Heat source and voiding signatures of Mullins damage in filled EPDM

Nicolas Candau, Oguzhan Oguz

The thermomechanical coupling of Mullins damage in filled EPDM has been investigated by analysing the self-heating via Infrared thermography (IR) and the voiding fraction by Digital Image Correlation (DIC). The volumetric strain measured during the rubber ...

Tensile response of UHPFRC under very low strain rates and low temperatures

Emmanuel Denarié, Mohamed Abdul Hafiz

This paper addresses the uniaxial tensile response of Strain Hardening Ultra High-Performance Fiber Reinforced Concretes (SH-UHPFRC) subjected to very low strain rates and low temperatures. The influence of four different strain rates; 1 × 10−5, 1 × 10−7, ...

Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii

Bruno Lemaitre, Samuel Rommelaere, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...

Nonreciprocal surface acoustic wave propagation via magneto-rotation coupling

Dirk Grundler, Mingran Xu

A fundamental form of magnon-phonon interaction is an intrinsic property of magnetic materials, the “magnetoelastic coupling.” This form of interaction has been the basis for describing magnetostrictive materials and their applications, where strain induce ...

Mechanics and co-evolution of allosteric materials and proteins

Riccardo Ravasio

The regulation of several processes inside and outside the cell depends on the action of a particular class of enzymes, called allosteric. In allosteric macromolecules, binding a ligand at one site affects the binding activity at a distal functional site, ...

A detailed view on the rebar–to–concrete interaction based on refined measurement techniques

Aurelio Muttoni, Miguel Fernández Ruiz, Raffaele Cantone

Simplified assumptions have traditionally been made on the rebar–to–concrete interaction in structural concrete to calculate the stress state in rebars. Such assumptions typically consider a uniform stress state in the reinforcement at a given cross sectio ...

Influence of humidity, temperature and prestretch on the dielectric breakdown strength of silicone elastomer membranes for DEAs

Herbert Shea, Fabio Beco Albuquerque

Humidity, temperature and membrane prestretch influence the dielectric breakdown strength of elastomer membranes. These three factors thus also influence the maximum force and strain that dielectric elastomer actuators (DEAs) can generate, as the Maxwell p ...

Cold Atmospheric Plasma Inactivation of Microbial Spores Compared on Reference Surfaces and Powder Particles

Alan Howling, David Martinet

Heat-resistant spores on a dry, heat- and water-sensitive food matrix are difficult to inactivate. Radioactive or X-ray exposure is allowed and accepted only for some selected commodities. Non-thermal atmospheric pressure plasma treatments could offer an e ...

Thermomechanical Nanostraining of Two-Dimensional Materials

Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Samuel Tobias Howell

Local bandgap tuning in two-dimensional (2D) materials is of significant importance for electronic and optoelectronic devices but achieving controllable and reproducible strain engineering at the nanoscale remains a challenge. Here, we report on thermomech ...

Open and Closed Radicals: Local Geometry around Unpaired Electrons Governs Magic-Angle Spinning Dynamic Nuclear Polarization Performance

David Lyndon Emsley, Gabriele Stevanato, Yu Rao, Dominik Józef Kubicki, Moreno Lelli, Manuel Cordova, Georges Guévork Jean-Jacques Menzildjian

The development of magic-angle spinning dynamic nuclear polarization (MAS DNP) has allowed atomic-level characterization of materials for which conventional solid-state NMR is impractical due to the lack of sensitivity. The rapid progress of MAS DNP has be ...
