Optical properties of single CsPbBr3 perovskite quantum dots synthesized by a modified ligand-assisted reprecipitation method
Marina Cagnon Trouche, Ernest Ruby, Margaux Cartier +5
Colloidal perovskite quantum dots (pQDs) are promising quantum light emitters, and investigations at the single pQD scale have so far relied mostly on hot-injection synthesis, whic…
Features of a nano-twist phase in the nanolayered Ti3AlC2 MAX phase
Julien Guénolé, Vincent Taupin, Maxime Vallet +2
Complex intermetallic materials known as MAX phases exhibit exceptional properties from both metals and ceramics, largely thanks to their nanolayered structure. With high-resolutio…
Sub-millisecond electric field sensing with an individual rare-earth doped ferroelectric nanocrystal
Athulya Muraleedharan, Jingye Zou, Maxime Vallet +5
Understanding the dynamics of electrical signals within neuronal assemblies is crucial to unraveling complex brain function. Despite recent advances in employing optically active n…
Heterogeneity in tribologically transformed structure (TTS) of Ti-6Al-4V under fretting
Vivien Lefranc, Soha Baydoun, Camille Gandiolle +4
Fretting wear is a surface degradation process caused by oscillatory motion and contact slipping. During gross slip, high local stresses and plastic deformation in the surface and…
