A plate Differential Mobility Analyser (DMA) is composed of two parallel plates between which aerosol-laden air flows. A specific device charges the aerosol particles electrically before they enter the DMA. Applying a voltage difference between the plates allows to deflect the particles ... En savoir plus
While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ...

The present work focuses on modeling a new experimental technique: Scanning Electro-chemical Potential Microscopy (SECPM), which is used to probe the potential profile of the electric double layer (EDL). We used an electrostatic approach to compute the EDL potential measured within the ... En savoir plus
Experiments in quantum computation using superconducting circuits involve fabrication of various microwave frequency structures like waveguide cavities, meander inductors, inter-digitated capacitors, etc. In order to optimize the design, we use finite element simulation using COMSOL ...

In “Micro-Electro-Mechanical-Systems” shortly known as MEMS, one of the most important and effective principle of creating transduction of electrical power to displacement force is thermal expansion. A slim beam of MEMS material, typically Silicon, is heated by the application of ... En savoir plus
Pulsed Electric Field (PEF) technology is gaining much attention in the food industry, as it offers unique advantages in terms of food safety, preservation of the organoleptic and nutrients properties, and low energetic requirements. Winemaking processes, in particular, can greatly ... En savoir plus
The actuation system of the deformable mirror is one of the crucial components of an Adaptive Optics unit. One possible implementation comprehends a linear force motor and a capacitive sensor providing the feedback measure signal. Choosing a magnetic circuit that makes optimum use of the ...

The study of the movement of solutes and their interaction with the solid phase of active clays is a problem of maximum interest in various geoenvironmental engineering applications, but especially in the deep geological disposal of spent nuclear fuel and other highly radioactive ... En savoir plus
Study of interaction of drops and bubbles with electric field is important for understanding the physics involved in various physical phenomenas and industrial processes. Important applications arise in colloidal systems (Miller and Scriven, 1970), meteorology and cloud physics (Sartor, ... En savoir plus
Finite elements using COMSOL Multiphysics have been used to simulate the edge plasma in a large area capacitively coupled RF reactor. In order to reduce numerical difficulties simplified reactor edge geometries have been used. First results show the importance of electrostatic double ... En savoir plus
