Volcanic eruptions are often preceded by periods of unrest, where the behavior of the volcano deviates from a background level towards one of increasing concern . Understanding what causes and contributes to unrest is a key challenge in volcanology today, influencing risk mitigation and hazard forecasting. Deformation of the volcanic edifice is one such indicator of unrest owing to a ...

This paper presents the results of modeling of a microreactor with three inputs geometry (or crow's-feet), in relation to distributions of velocities and concentrations. The objective of this work is the study of this kind of geometry with relation to fluid dynamics behavior, improving the knowledge of microfluidics and microreactors projects. These numerical responses allow conclusions about ...

COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows consideration of mantle compressibility using the CFD Module and I benchmarked COMSOL Multiphysics using ...

Our laboratory is currently leading the design and the manufacture of a novel device that allows NMR spectroscopy to be cooled down to cryogenics temperature (in the 10-100 K range). The system features a sample-holder that rotates at very high frequencies (f >10 kHz). Two aerostatics gas-bearings, allows this sample holder to be suspended in its chamber thanks to a Helium flow. A second Helium ...

One of the major challenges in biology concerns the integration of data across length and time scales into a consistent framework: how do macroscopic properties and functionalities arise from the molecular regulatory networks and how do they evolve? A deeper understanding of morphogenesis and organogenesis in particular is required to advance tissue engineering. Recent advancements in 3D ...

Ion implantation in insulating materials leads to local variations in mechanical and optical properties that can be exploited for the fabrication of micro-structures. In particular, ion irradiation of diamond causes the formation of buried amorphised layers, with correspondent mass density and refractive index variations that depend on the level of “damage” of the crystal structure. ...

A small particle or a nano-sized object placed in a liquid is subject to random collisions with solvent molecules. The resulting erratic movement of the object is known as Brownian motion, which, in nature, cannot be used to any practical advantage both in natural systems (such as biomolecular motors) or by artificial devices. If energy is supplied by external source or by chemical reactions, ...

Tunnels and their detection have been a problem in warfare since the ancient world. Recent events have highlighted the ongoing problems of tunnels and the difficulties in locating them, not only in military situations, but also in law enforcement and homeland security applications as well. Electromagnetic and acoustic or seismic techniques may provide the significant advantage of a mobile non ...

Mass transport modelling through porous media is typically characterized by complex physics and geometry. In the particular case of radionuclide transport, modelling for radioactive waste repositories, an additional level of complexity, and thus uncertainty, originates from the long time frames involved. Performing a safety analysis of a radioactive waste disposal system requires therefore ...

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...
