Control of the Microstructure in Ceramics

Anne Leriche, Stuart Hampshire, Francis Cambier

Ceramic materials are commonly fabricated by powder processing and a subsequent heat treatment, which results in the elimination of about 40 vol% of porosity during the sintering step. The densification occurs at high temperature allowing atom diffusion in the solid state or through a liquid phase…

Linear hyperbolic systems on networks: well-posedness and qualitative properties

Marjeta Kramar Fijavž, Delio Mugnolo, Serge Nicaise

We study hyperbolic systems of one-dimensional partial differential equations under general, possibly non-local boundary conditions. A large class of evolution equations, either on individual 1-dimensional intervals or on general networks, can be reformulated in our rather flexible formalism, which…

Enhancement of both optical and catalytic activity of copper-decorated porous silicon micro-particles

Abderrahmane Hamdi, Chohdi Amri, Rachid Ouertani, El Hadj Dogheche, Hatem Ezzaouia

To the best of our knowledge, this study is the first to investigate the effect of chemical vapour etching (CVE) combined with copper decoration on both the optical and catalytic activities of silicon micro-particles (SiμPs). After exposure to acid vapours emanating from a hot solution of hydrogen…

An optimal control problem governed by heat equation with nonconvex constraints applied to selective laser melting process

Tonia-Maria Alam, Serge Nicaise, Luc Paquet

This paper deals with a PDE-constraints optimal control problem applied to an Additive Manufacturing process, namely a selective laser melting. Here, we want to control the temperature gradient inside the domain during a fixed time of heating, by acting on the trajectory of the dynamic Gaussian…

Four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature

Zhida Guan, Haizhong Li, Luc Vrancken

In this paper, through making careful analysis of Gauss and Codazzi equations, we prove that four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature. Our result gives the positive answer to the conjecture proposed by Balmuş–Montaldo–Oniciuc in 2008 for four…
