The Mammalian Membrane Microenvironment Regulates the Sequential Attachment of Bacteria to Host Cells

Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Zaïnebe Dhirani, Jeremy Pak Hei Wong

Pathogen attachment to host tissue is critical in the progress of many infections. Bacteria use adhesion in vivo to stabilize colonization and subsequently regulate the deployment of contact-dependent virulence traits. To specifically target host cells, th ...

Multiscale Modeling Strategy of 2D Covalent Organic Frameworks Confined at an Air-Water Interface

Andres Adolfo Ortega Guerrero

Two-dimensional covalent organic frameworks (2D COFs) have attracted attention as versatile active materials in many applications. Recent advances have demonstrated the synthesis of monolayer 2D COF via an air-water interface. However, the interfacial 2D p ...

Bridging scales in wear modeling with volume integral methods for elastic-plastic contact

Lucas Henri Galilée Frérot

All mechanical systems, naturally occurring or human-produced, are subjected to friction and wear at the interface of solid constituents. Large portions of energy dissipation and loss of material, in every-day life and industrial applications alike, are du ...

Role of interfacial adhesion on minimum wear particle size and roughness evolution

Jean-François Molinari, Ramin Aghababaei, Tobias Brink, Enrico Milanese

Adhesion between two bodies is a key parameter in wear processes. At the macroscale, strong adhesive bonds are known to lead to high wear rates, as observed in clean metal-on-metal contact. Reducing the strength of the interfacial adhesion is then desirabl ...

Transition from Exponentially Damped to Finite-Time Arrest Liquid Oscillations Induced by Contact Line Hysteresis

François Gallaire

To clarify the role of wetting properties on the damping of liquid oscillations, we studied the decay of oscillations of liquid columns in a U-shaped tube with controlled surface conditions. In the presence of sliding triple lines, oscillations are strongl ...

Resistance and ductility of FRP composite hybrid joints

Thomas Keller, Lulu Liu

An experimental investigation of the load-bearing behavior and ductility of FRP hybrid double-lap joints composed of both adhesively-bonded and bolted connection parts was conducted. Amongst other things, the effects of the adherends’ fiber architecture (u ...

Carbon Nanomaterials from Oligoyne Surfactants

Enzo Jean Raymond Bomal

Carbonaceous nanocoatings such as diamond-like amorphous carbon or graphene layers exhibit remarkable properties in multiple fields, ranging from corrosion protection to electronics and lubrication. However, they are typically deposited from the vapor phas ...

Light-Activated, Bioadhesive, Poly(2-hydroxyethyl methacrylate) Brush Coatings

Dominique Pioletti, Harm-Anton Klok, Jian Wang, Peyman Karami, Nariye Cavusoglu Ataman

Rapid adhesion between tissue and synthetic materials is relevant to accelerate wound healing and to facilitate the integration of implantable medical devices. Most frequently, tissue adhesives are applied as a gel or a liquid formulation. This manuscript ...

Review of fatigue of bulk structural adhesives and thick adhesive joints

Anastasios Vassilopoulos

Fatigue of structural adhesives has been investigated through joints and a little number of works investigate bulk adhesive behaviour itself. Aerospace and automotive engineering focuses more on joint configuration studies, which are correlated with practi ...

Energy dissipation in adhesive and bolted pultruded GFRP double-lap joints under cyclic loading

Thomas Keller, Sonia Yanes Armas, Ghazaleh Eslami

Fiber-reinforced polymer (FRP) structures, due to their low mass, are valuable alternatives to traditional steel or concrete structures in seismic areas. However, to resist seismic actions, FRP structures must be able to dissipate a significant amount of i ...

The Effect of Material Fresh Properties and Process Parameters on Buildability and Interlayer Adhesion of 3D Printed Concrete

The advent of digital concrete fabrication calls for advancing our understanding of the interaction of 3D printing with material rheology and print parameters, in addition to developing new measurement and control techniques. Thixotropy is the main challen ...
