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

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

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 ...

Microfluidic devices for the study of cell-cell, cell-particle and particle-particle interactions

Margaux Catherine Marie Duchamp

Microfluidics and microtechnologies are of great interest for biological applications. This interest is linked to the fact that microtechnologies enable the study of single cells at the cellular and sub-cellular level. One of many applications of such sing ...

Understanding the effects of material properties and operating conditions on component aging in polymer electrolyte water electrolyzers

Ugljesa Babic, Mohamed Tarik, Thomas Justus Schmidt

If polymer electrolyte water electrolysis (PEWE) is to penetrate the energy market in the context of power-to-x, challenges related to component durability need to be understood and addressed. In this study, PEWE component degradation mechanisms are induce ...

Microfluidic device performing on flow study of serial cell–cell interactions of two cell populations

Philippe Renaud, George Coukos, Thamani Dahoun, Margaux Catherine Marie Duchamp, Alexandre Harari, Marion Arnaud

In this study we present a novel microfluidic hydrodynamic trapping device to probe the cell–cell interaction between all cell samples of two distinct populations. We have exploited an hydrodynamic trapping method using microfluidics to immobilize a batch ...

Mutation update: TGFBI pathogenic and likely pathogenic variants in corneal dystrophies

Human transforming growth factor beta-induced (TGFBI), is a gene responsible for various corneal dystrophies. TGFBI produces a protein called TGFBI, which is involved in cell adhesion and serves as a recognition sequence for integrins. An alteration in cel ...

Quantifying Guest-Host Dynamics in Supramolecular Assemblies to Analyze Their Robustness

Maartje Martina Cornelia Bastings, Eva Eugene Kurisinkal

The most basic function of synthetic microenvironments for tissue engineering is to act as a physical substrate for cell attachment, migration, and proliferation, similar to the natural cell environment. Functionalization of supramolecular materials with g ...

Dielectrophoresis‐assisted creation of cell aggregates under flow conditions using planar electrodes

Philippe Renaud, Harald Van Lintel, Jonathan Bastien Cottet, Soufian Lasli

We present a microfluidic platform allowing dielectrophoresis-assisted formation of cell aggregates of controlled size and composition under flow conditions. When specific ex- perimental conditions are met, negative dielectrophoresis allows efficient conce ...

Ultraviolet Functionalization of Electrospun Scaffolds to Activate Fibrous Runways for Targeting Cell Adhesion

Silvestro Micera

A critical challenge in scaffold design for tissue engineering is recapitulating the complex biochemical patterns that regulate cell behavior in vivo. In this work, we report the adaptation of a standard sterilization methodology-UV irradiation-for pattern ...

Structure and Function of the Branched Receptor-Binding Complex of Bacteriophage CBA120

Sergey Nazarov, Petr Leiman, Sergii Buth, Nikolai Prokhorov, Michel Plattner

Bacteriophages recognize their host cells with the help of tail fiber and tailspike proteins that bind, cleave, or modify certain structures on the cell surface. The spectrum of ligands to which the tail fibers and tailspikes can bind is the primary determ ...

New Binding Sites, New Opportunities for GPCR Drug Discovery

Horst Vogel, Thamani Dahoun, Shuguang Yuan, Yen-Huan Li

Many central biological events rely on protein-ligand interactions. The identification and characterization of protein-binding sites for ligands are crucial for the understanding of functions of both endogenous ligands and synthetic drug molecules. G prote ...
