Wafer bonding technology has become a crucial process in 3D IC integration, particularly as a key method for monolithic integration where Through-Silicon Via (TSV) technology is not used [1]. However, due to the intricate mechanical stress and interconnect reliability issues associated ... En savoir plus

Nuclear fusion represents a promising solution for providing clean and sustainable energy. However, to support fusion reactions, tritium, a rare isotope, must be continuously produced within the reactor. Breeding blankets, which surround the plasma, produce this tritium. These components ... En savoir plus

This study focuses on optimizing the lengths of various structural components around a cylinder to minimize drag. Using COMSOL Multiphysics, numerical simulations involving Laminar Flow were performed. Key components optimized include an arrowhead positioned upstream and two flaps ... En savoir plus

Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus

The transfer molding process is a widely used method for encapsulating microelectronics and power semiconductor devices. In power electronics, it is gaining increasing importance, particularly in the automotive sector [1]. In transfer molding, an epoxy mold compound (EMC) is injected ... En savoir plus

This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... En savoir plus

The WaveEL buoy developed by the company Waves4power is characterized as a point absorber and has a 36 meters long vertical cylinder where a water-piston is oscillating due to induced motion from the waves. Estimating the wave loads on the piston is a challenge due to the presence of ... En savoir plus

A pneumonectomy is an invasive, high-risk surgical procedure performed to remove the right or left lung. Although this may be a life saving procedure for some patients, it has high morbidity rates and many complications post-pneumonectomy. Pneumonectomies result in the heart’s entire ... En savoir plus

We present a problem-adapted finite element model, which enables the design of a novel type of a highly miniaturized, electrostatic MEMS membrane pump, as well as the investigation and the optimization of its operation. The electro-mechanical actuation scheme constitutes a strongly ... En savoir plus

Started in March 2020, the SOFITT project (Saturated Open-Cell Foams for Innovative Tribology in Turbomachinery), funded by the ANR (French National Research Agency), aims to develop reliable, high-performance, and environmentally friendly solutions for the guidance and support systems ...
