Liquid crystals are substances with one or more states of matter between the crystalline solid and the usual liquid. These liquid-crystal states are characterized by the specific, microscopic organization of …
Understanding how materials absorb light on the nanometer scale is essential for applications in photonics and quantum optics. By superimposing a laser beam and an electron beam in an electron …
In collaboration with researchers from the Institut de Biologie Intégrative de la Cellule, the SOLEIL synchrotron and the University of California, Riverside, a team from the Laboratoire de Physique des …
From chocolate mousse to shaving foam and insulating foams, foams are ubiquitous in everyday objects. A better understanding of their mechanical behavior opens up a wide range of applications. Liquid …
Interactions emerging at the interface of an ultrathin magnetic layer, such as the Dzyaloshinskii-Moriya (DMI) antisymmetric exchange interaction, can lead to the appearance of particular spin orientations within the layer, …
The configuration and geometry of chemical reactors determine reliability when assessing the performance of photocatalytic materials. Researchers have developed a novel automated photoreactor for H2 production that substantially improves the …
Two young researchers from the STEM group, Nadezda Varkentina (former postdoc) and Yves Auad (Ph.D) have received the 2022 Outstanding Paper Award from the European Microscopy Society in the Instrumentation …
Unlike squares, triangles, or hexagons, pentagons cannot completely tile the plane. Using silver nanoprisms with a pentagonal cross-section, researchers have reproduced theoretically predicted tilings and determined the mechanisms that allow …
Foams are unstable jammed materials whose growth mechanisms remain poorly understood. A recent study has demonstrated a dominant effect of the viscoelasticity of the continuous phase on the cellular structure …
Rectification of an optical signal using an all-metallic electronic device is of fundamental and technological importance for nano-optics. Researchers probed experimentally the microscopic mechanism at the origin of the optical …
