Spontaneous electric polarization, a phenomenon called ferroelectricity, occurs in a material when the spatial distributions of positive and negative charges differ. It is therefore intimately related to the symmetry of …
The LPS STEM group and their collaborators have unveiled the interaction of phonons and plasmons at the nanometer scale. This interaction, which is discussed in an article just published in …
In some conditions, very elongated rod-like silver nanoparticles can be grown on gold seeds. What is the origin of this surprising shape? LPS researchers, in collaboration with the MPQ laboratory …
Epidemiological studies show a clear increase in renal lithiasis in most western countries, induced by changes in eating habits and lifestyle. Almost 20% of the population will be affected by …
Is it better to take a smooth or a rough spoon to eat your chocolate mousse? That is the question that a team from the LPS answers by studying the …
In physics, chemistry or biology, reaction rates are very often limited by energy barriers that have to be overcome by thermal activation. Researchers from LPS, LPTMS (CNRS/U. Paris Saclay) and …
RNA viruses are a family of infectious agents with sometimes dramatic health and economic consequences such as those we are currently experiencing. Over the course of a life cycle, viral …
Clays are lamellar minerals ubiquitous on the earth’s surface. Researchers at IC2MP, LPS and ICMN have shown that the preferred orientation of clays in a wide variety of natural environments …
A major challenge in the study of high temperature superconductivity in copper oxide materials is to understand their macroscopic quantum behavior in terms of microscopic mechanisms. Using the electric field …
Direct observation of topological properties of materials is now possible in experiments on mesoscopic samples, including measurement of “winding numbers” — which were until now considered rather abstract properties of …
