Seminar by Pr. Hiroshi Fukumura

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.


Seminar Kevin Kubarych

Kevin Kubarych, from the University of Michigan, is visiting our lab today and tomorrow with two of his collaborators. He will give a seminar entitled

Exploring Vibrational Polariton Dynamics with Ultrafast Two-Dimensional Infrared Spectroscopy

this afternoon, October 8, at 2.30pm in the meeting room of ISIS.

On the roof of Collège de France

Some souvenir de Paris…where all the team, or almost, had a pleasant and interesting colloquium in a wonderful place ! It was also a good opportunity to meet some of our former members. Four of them are hidden in the picture, would you recognize them ?

E-MRS Quinquennial anniversary award

The E-MRS Anniversary Award recognizes the career contribution of a scientist to fundamental understanding of the science of materials through experimental and/or theoretical research.” It is attributed every five years and after Sir Richard Friend, Prof. Dan Schechtman and Sir John Pendry,  the award has been attributed this year to …  Prof. Thomas Ebbesen !

He will receive it during the E-MRS conference plenary session on Wednesday 20th June in Strasbourg, where he will deliver a presentation on

Light-Matter Interactions in a Material Science Perspective.


Colloquium in College de France

Next week, on June 18 and 19, and in the framework of the Chaire Annuelle d’Innovation Technologique Liliane Bettencourt, a colloquium organized by Thomas Ebbesen will take place in College de France, Paris, entitled

New QED Landscapes for Molecules and Materials 

The speakers will be a mix of former or actual collaborators from our group and world recognized specialists in the field and the detailed program is visible here below.


Venga Yoseline !

Tomorrow, June 13, at 9.15am, our phD student Yoseline Rosales-Cabara will lead the summer edition of the Young Scientist Seminar of ISIS, with a talk entitled
