Researchers at the Laboratoire Léon Brillouin (CEA-CNRS), Univ. Paris-Saclay have demonstrated that ordinary liquids can emit a modulated hot and cold thermal signal upon applied mechanical shear wave (Figure below). It tells that the mechanical energy is not dissipated but converted in local thermodynamic states. Prof. Laurence Noirez together with her student Eni Kume (ESR 5) thus identified the equivalent of the thermo-elasticity which was known in solids only.These experimental advances are utmost important for liquid theories and microfluidics, and open the way to a new generation of energy-efficient temperature converters. View the article By applying a low frequency shear mechanical stimulus (~ Hz), the liquid emits a modulated thermal signal synchronous with the stimulus.

The team successfully imaged water flow imbedded in ferrofluid enclosure, stabilized by magnetic forces. X-ray tomography 3D imaging was performed at PSI synchrotron (CH), in a new collaboration, which validated the full shape of the microfluidic circuitry, as well as the accuracy of the optical method used IPCMS laboratory in parallel. The team is now capable of stabilizing and imaging tubes of 15 microns diameter, more than one order of magnitude smaller than before. This finding a key for showing how this approach is relevant for the field of microfluidics, in particular for flowing very viscous liquids or very delicate biological compounds. These results are published in latest issue in Nature Dunne, P., Adachi, T., Dev, A.A. et al. Liquid flow and control without solid walls. Nature 581, 58–62 (2020).…

From 27.01 to 29.01 the Students from European Project MAMI have been working on different projects related to microfluidics: paper microfluidics, 3D printed microfluidics, cells on a chip and polymer fabrication of microfluidic devices.   On Monday 27th of January MAMI students visited Microliquid facilities in Arrasate-Mondragón. They learnt about mass scale fabrication of microfluidics devices, visited their facilities and enjoyed a great microfluidics industrial experience!
