Kalaivanan Nagarajan left our lab one week ago to go back in India where he will take a position of reader at the Department of Chemical Sciences of TIFR, Mumbai. He spent 5 years in the lab, during which he had time to build strong relationships with people here, to evolve as a scientist with a pure chemistry education to a much more physics one and to forge a family. His presence in the team was precious thanks to his energy and enthusiasm. No doubt that his new colleagues will benefit from this and we wish him all the best for the future !
Today, we have the pleasure to welcome Pr Hiroshi Fukumura (KU Leuven, Belgium, & Tohoku University, Japan) who will give a talk at 11am in the Salle de Conférence of ISIS, entitled
“Liquid-liquid phase separation dynamics: hierarchy from molecular level to continuous bulk”
Here below you can find the abstract of his talk :
Pulsed laser induced liquid-liquid phase separation has been studied with various time-resolved techniques. Time-resolved Raman spectroscopy and fluorescence spectroscopy revealed molecular level changes immediately after the laser pulses up to 1 . Ultrafast imaging under conventional microscopes showed macroscopic changes started 10 after the laser pulse. The macroscopic phase separation seemed to follow spinodal decomposition described by Kahn-Hilliard theory. It is, however, yet unclear what occurs in the time range between 1 and 10 . Recently we have succeeded in observing this time range with time-resolved structured illumination as well as optical diffraction techniques. Possible explanation of our results would be that mesoscopic entities like micelle-like structures mediate between molecular level changes and macroscopic spinodal decomposition. Related topics like liquid-liquid phase separation in living cells, critical Casimir force in binary liquids, laser ablation and implantation of polymer surfaces may be introduced.
On wednesday, 1st of June, during the ITI QMat scientific day held at IPCMS, Rémi Goerlich won the 1st prize for his poster “Harvesting information to control non-equilibrium states of active matter”.
Congratulations to him !
