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 ...

Biomemebranes are characterized by several elastic parameters that appropriately describe the energetics of their deformation under thermal fluctuations [1]. When their structure is quasi-two-dimensional (namely lipid bilayer 4-5 nm thick), several recent studies [1,2] showed that their ... En savoir plus
Present work is done in the framework of the SisAl Pilot EU project, which aims at optimising the silicon production in Europe by recycling materials and using a carbon-emission friendly technology. The silicon production experiments are conducted on laboratory and pilot scales in ... En savoir plus
Radiofrequency discharges in Hydrogen have a range of applications. In particular, they are used as high-intensity sources of atoms for fundamental and material processing applications. In this study, we investigate a small volume, low pressure RF discharge used to produce Hydrogen ... En savoir plus
While the modelling of smooth concentrated contact lubrication has been achieved a few decades ago [1], the engineer is often left with no other option than to neglect many aspects of real-world contacts. Among these aspects, the contribution of roughness in lubricated contacts is ... En savoir plus
Condenser microphones will have an electrical output for any displacement of the membrane relative to the back plate, which is usually bound to the microphone housing. For the typical use case, a pressure input will create a pressure difference across the membrane, which causes a ... En savoir plus
In the field of electron optics, precise control of magnetic fields is crucial for achieving high-performance outcomes in various applications, particularly in the semiconductor and chip production industry. As the demand for high-precision semiconductor production continues to grow, the ... En savoir plus
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
The objective of this simulation model is to enhance the thermal behavior in a MEMS Gas-Chromatographer (GC) pre-concentrator for Volatile Organic Compounds (VOCs) carried by Helium gas. The simulation plays a critical role in estimating voltages, thermal time constants, and spatial ... En savoir plus
Electrodialysis (ED) is a unit operation for the separation of electrolytes with numerous applications in the chemical, food and biotechnological fields. Its modeling requires estimating several parameters and performing many batch desalination experiments (Fidaleo and Moresi, 2005). ... En savoir plus
