High voltage (HV) stability is an important requirement in many technical areas. The prevention of partial discharges or flashovers requires careful mechanical and electrical design of all components with high electric potential difference towards the surrounding. In the Semiconductor ... En savoir plus

Among the various technological platforms, which are currently investigated as candidates for the implementation of large-scale multi-qubit quantum computers, spin qubits in silicon quantum dots (QDs) are one of the most attractive. Long spin lifetimes can indeed be achieved in ... En savoir plus

Spinal cord injury triggers an initial inflammatory response followed by scar tissue formation, hindering the repair of severed neural tracts and sensorimotor function.1 Injectable hydrogels consisting of a water-swollen polymer network can be engineered to mimic the environment of ...

In the field of industrial marking, continuous inkjet technology is based on high speed emission of ink drops. The printing quality is directly linked to the interactions of the droplets with their environment during flight time : electric field, aerodynamic perturbations, and droplet ... 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

A critical element in understanding the pre-breakdown and breakdown mechanisms in gas/solid insulation systems is the triple point. This point is where two dielectric materials and a conductor intersect. Understanding these mechanisms at the triple point is crucial for designing systems ... En savoir plus

A substantial campaign of simulations was recently launched in the Bonomi Group with the goal of improving the understanding of the multiphysics involved in high voltage equipment such as aerial power lines, insulators, surge protectors and disconnectors. The activity not only resulted ... En savoir plus

Gallium Oxide (β-Ga2O3) is an emerging wide bandgap oxide semiconductor that has garnered attention for power electronic applications because of its large 4.8 eV bandgap energy and critical electric field strength of ~ 8 MV/cm [1]. However, due to Gallium Oxides' poor thermal ... En savoir plus

In the field of coding and industrial marking areas, CIJ technology is based on high speed emission of ink drops (20 m/s) which are directed onto a moving printing medium. The printing quality depends, on one hand, on drops position on the media determined by the drop charge and the ... En savoir plus
