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 …
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 …
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 …
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 …
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. …
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 …
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 …
Each year, about 150 faculty from all disciplines and from universities throughout France are appointed for five years to the Institut Universitaire de France (IUF), whose mission is to promote …
Cover of EPJ B’s June issue is illustrated by the main figure of article « Topology of contact points in Lieb-kagomé model », by Gilles Abramovici. This object, called classification surface, is …
The story of liquid crystals is that of transgression of frontiers and of breaking of common beliefs. Indeed, liquid crystals were discovered by a biochemist, Friedrich Reinitzer, who shared his …
