Improvement of wear and corrosion protection of PEO on AA2024 via sol-gel sealing

Luciane Sopchenski, Julien Robert, Matthieu Touzin, Arnaud Tricoteaux, Marie-Georges Olivier

Plasma electrolytic oxidation (PEO) is a versatile and cost-effective technique to obtain protective oxide coatings in light metals, although its intrinsic porosity is a drawback for long-term corrosion resistance. Sol-gel layers are pointed as a useful tool to seal PEO porosity and increase its…

MULTIPLE BOUNDED VARIATION SOLUTIONS FOR A PRESCRIBED MEAN CURVATURE EQUATION WITH NEUMANN BOUNDARY CONDITIONS

Alberto Boscaggin, Francesca Colasuonno, Colette De Coster

We prove the existence of multiple positive BV-solutions of the Neumann problem - (u'/\sqrt{1+{u'}^2})' = a(x)f (u) in (0, 1), u (0) = u (1) = 0, where a(x) > 0 and f belongs to a class of nonlinear functions whose prototype example is given by f (u) = −λu + u^p, for λ &gt…

Effect of spray drying treatment on the optical properties of Mg–Al spinel ceramics

Robin Stocky, Judith Boehmler, Sébastien Lemonnier, Pierre Gibot, Yannick Lorgouilloux, Anne Leriche

In recent years, Mg–Al spinel ceramic has been in the spotlight due to its large transparency range and goodmechanical properties. The aim here, was to control the state of agglomeration of powder to improve densifi-cation behaviour and consequently optical and mechanical properties of the ceramics…

Guaranteed Quantity of Interest Error Estimate Based on Equilibrated Flux Reconstruction

Zuqi Tang, Suyang Lou, Abdelkader Benabou, Emmanuel Creusé, Serge Nicaise, Julien Korecki, Jean-Claude Mipo

The quality of a local physical quantity obtained by the numerical method, such as the finite element method (FEM), attracts more and more attention in computational electromagnetism. Inspired by the idea of goal-oriented error estimate given for the Laplace problem, this work is devoted to a…

Homotopy perturbation technique for improving solutions of large quadratic eigenvalue problems: Application to friction-induced vibration

Jérémy Sadet, Franck Massa, Thierry Tison, Isabelle Turpin, Bertrand Lallemand, El-Ghazali Talbi

This paper puts forward a projection technique for accurately calculating solutions of large Quadratic Eigenvalue Problem. The aim here is to stabilize the complex eigensolutions whilst reducing residual errors, especially when considering significant damping contribution or asymmetric stiffness…

Facile synthesis of fluorine-free, hydrophobic, and highly transparent coatings for self-cleaning applications

Abderrahmane Hamdi, Julie Chalon, Pascal Laurent, Benoit Dodin, El Hadj Dogheche, Philippe Champagne

Non-fluorinated coatings have recently emerged as a new approach to avoid contamination on transparent surfaces. This research work concerns the synthesis of highly transparent, hydrophobic, durable, and self-cleaning coatings as an alternative to fluorine-based coatings used on glass. The…

Weighted $$L^2$$ Version of Mergelyan and Carleman Approximation

Séverine Biard, John Erik Fornæss, Jujie Wu

Abstract We study the density of polynomials in H2 ( E , φ ) , the space of square integrable functions with respect to e−φdm and holomorphic on the interior of E in C, where φ is a subharmonic function and d m is a measure on E . We give a result where E is the union of a Lipschitz graph and a…

On the nonexistence and rigidity for hypersurfaces of the homogeneous nearly Kähler S3×S3

Zejun Hu, Marilena Moruz, Luc Vrancken, Zeke Yao

In this paper, we study hypersurfaces of the homogeneous NK (nearly Kähler) manifold S3×S3. As the main results, we first show that the homogeneous NK S3×S3 admits neither locally conformally flat hypersurfaces nor Einstein Hopf hypersurfaces. Then, we establish a Simons type integral inequality…

Development of Femtosecond Laser-Engineered β-Tricalcium Phosphate (β-TCP) Biomimetic Templates for Orthopaedic Tissue Engineering

Albena Daskalova, Liliya Angelova, Anton Trifonov, Marie Lasgorceix, Stephane Hocquet, Mendy Minne, Heidi Declercq, Anne Leriche, Dante Aceti, Ivan Buchvarov

Reconstruction of bone tissue defects is a problematic area of the modern world. Temporary “platforms” of various materials for improving cell adhesion and proliferation have been extensively researched in recent decades. β-tricalcium phosphate (β-TCP) is a suitable biocompatible, biodegradable…

Rational energy decay rate for the wave equation with delay term on the dynamical control

Gilbert Bayili, Serge Nicaise, Roland Silga

We consider the wave equation with a delay term in the dynamical control. If the delay term is small enough, we establish the strong stability of this system, but show that it is not exponentially stable. We then prove that the system with delay has the same rational decay rate than the one without…
