In our laboratory LIN we develop unique scientific instruments, components and sample environment devices, mainly for the neutron spallation source SINQ in Switzerland. There are also in kind contributions to the European spallation source ESS in Lund, Sweden. I use COMSOL Multiphysics® ... En savoir plus
The electromagnetic study for the design of microwave ovens requires knowledge of the electric permittivities of the materials within the chamber. In some cases, data can be easily obtained from the literature, as with Teflon, Mica, and borosilicate glass. However, for more advanced ... En savoir plus
The contamination of food products with low water contents is a safety issue that cannot be disregarded. Despite their low water activity, they are indeed susceptible to infection by micro-organisms that are highly resistant to heat. In this case, conventional pasteurisation techniques ...

In this paper, the topic of magnetic particle separation in a liquid column based on magnetophoresis is studied in depth. Magnetic powders are important basic materials for filaments, pastes and inks that need to exhibit magnetic properties. The geometric dimensions of the particles are ... En savoir plus
Quasi-static 2D-MEMS vector scanners are micro-opto-electro-mechanical systems (MOEMS) made of monocrystalline silicon. The primary application for these controllable micromirrors is the high dynamic and precise deflection of laser beams, for example in light detection and ranging ... En savoir plus
Design of the electromagnetic system requires a procedure where certain parameters need to be maximized under constraints placed on its dimensions. Optimization routines that can maximize the function value under given constraints are required. Design of such systems coupled with the ... En savoir plus
Obtaining a good coverage of Digital Audio Broadcasting (DAB) service, in the 200 MHz band, in motorway tunnels is quite a challenging task. Recently, Rai Research Centre (CRITS) has been involved in investigating alternative (and cheaper) solutions than those adopted so far (radiating ... En savoir plus
The goal of this study is to exploit the phase change in vanadium dioxide (VO₂) for optical sensing. Infrared (IR) sensing is of paramount interest for next-generation Internet of Things (IoT) devices. Phase change materials (PCMs) are expected to enable low-energy consumption sensors, ...

Due to the increase on the academic and industrial interest on thermal energy storage (TES) systems, the EU Horizon project HYSTORE is developing 4 different solutions. In these solutions, the use of thermochemical materials (TCM) and phase-change materials (PCM) are proposed. We ... En savoir plus
The aim of this work is to compute the mechanical forces in a 12-pulse converter transformer winding in different short-circuit modes. A 12-pulse converter transformer is a three phase transformer with two secondary windings whose tension have 30° phase displacement and one primary ... En savoir plus
