Modifying solid surfaces, the daily life of bacteria
Unveiling how bacteria modify the surface of solid walls in their close environment at the nanoscale is an important step in nanotechnology and bioengineering as well as in geomicrobiology and …
Bronze medal presentation to Freek Massee
On November 25, the CNRS Delegation IdF Gif-sur-Yvette awarded the bronze medal to Freek Massee, CNRS research fellow at the Laboratoire de Physique des Solides, in the presence of Frédéric …
Mechanical
The service was created in 1998 by pooling the various mechanical skills of the laboratory. It supports the design and construction of the mechanical parts of scientific instruments and provides …
Efficient and tunable nanoscale light emitters with improved resistance!
Lead halide perovskites (LHPs) with composition CsPbX3 (X a halide, such as I, Cl, Br) have attracted intensive focus from the scientific community due to technological advances in the areas …
Liquid crystals: a playground for exploring physics
The teaching of experimental physics at the Master’s level has recently undergone a notable evolution thanks to the setting up of platforms equipped with state-of-the-art equipment, similar to that used …
The exposition “La science taille XX Elles” comes to the LPS
On the occasion of the 80th birthday of the CNRS, the association Femmes & Sciences and the CNRS have joined forces to promote women in science, to counteract stereotypes that …
What is the best recipe to blow giant bubbles?
Fragile, short-lived, fascinating, soap bubbles and in particular giant ones are often used by artists to accompany their acts. Each artist has a recipe that allows him to optimize his …
A Fréedericksz-like transition in a biaxial smectic A phase
Liquid-crystal (LC) displays exploit a physical phenomenon called the Fréedericksz transition. This effect is only observed with “nematic” LCs which are fluids of rod-like molecules aligned in the same direction. …
Original structure and dynamics of water in a geo-inspired nanotube – SFN 2021 thesis prize
The study of ultra-confined fluids opens a very large field concerning nano-flows and it highlights the determining role of interfaces in new structures of liquids such as water. The development …
An ultrafast and bright transmission electron microscope!
Linking the properties of light and the structure of a material at the nanometer scale provides valuable information for the development of optoelectronic devices. Physicists have measured for the first …
