A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... En savoir plus
High temperature thermodynamic data are crucial for a wide variety of applications in nuclear and aeronautic domains as well as material production processes like glass formation or casting. Contactless acquisition methods are preferred to avoid chemical interactions with the container. ... En savoir plus
In industrial oxygen systems at high temperature and high pressure, contamination by solid particles is one of the principal causes of ignition hazards. Indeed, gas can sweep away particles, generated by corrosion inside the pipes or during maintenance operations (welding residues, ... En savoir plus
Additive manufacturing processes are increasingly used for designing metallic parts with complex geometries. The current needs are focused on the manufacturing of large-scale parts, typically of meter range. However, for such dimensions, the traditional trial-and-error methodology used ... En savoir plus
The next step in the evolution of the metal sector of Additive Manufacturing and especially for Laser based Powder Bed Fusion is the production of multi-material components as shown by [1]. Therefore, the powder application module must be able to selectively arrange different powders in ... En savoir plus
The demand of the data storage continues increasing with the development of the big data, cloud computing technologies. Heat-assisted magnetic recording (HAMR) technology is the most promising technology for data storage to push the areal density up to 10 Tb/in2. In HAMR, the laser ... En savoir plus
Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the ... En savoir plus
The advanced gravitational wave detectors require injecting a high continuous power laser into the optical cavities of the interferometers to reach their design sensitivity. To mitigate the thermal aberrations created by absorption of this high power load into the various optical ... En savoir plus
The importance of laser processing and thermal properties investigation of bulk materials and thin layers is still increasing. For thermal properties investigation many experimental systems were developed based on the photothermal effect. One of typical ways is to induce a rapid surface ... En savoir plus
