Ultrafast Exciton Dynamics in 2D van der Waals Nanostructures: Probing the Hot Exciton Relaxation of Size-Controlled & Well-Dispersed Graphene Nanoflakes

Graphene nanostructures, such as graphene quantum dots (G-QDs), graphene nanoribbons (G-NRs) and carbon nanotubes (C-NTs), combine the unique mechanical and electronical transport properties of sp2- hybridized carbon materials and the optical…

Temperature-mediated backaction in micromechanical and nanomechanical resonators

We theoretically investigate the thermally induced back-action effects in absorption-sensitive micro-and nanomechanical resonators. We propose a unified approach, enabling to simultaneously address both the effective dynamics and non-equilibrium…

Design of new nano-tools to target mitochondria and study the metabolic plasticity of cancer cells

Metabolic plasticity and mitochondrial function are crucial in tumorigenesis and cancer therapy response, making mitochondria a key target for novel treatments (1-2). Bioactive molecules, modulating mitochondrial activity, offer alternative…

3D Real-Time Single Particle Tracking using two-photon fluorescence from bright dye-based organic nanoparticles

This paper addresses the use of ultrabright dye-based fluorescent organic nanoparticles in a 3D single-particle tracking two-photon microscopy setup. The nanoparticles consist of an assembly of quadrupolar dyes, presenting a large twophoton…

Physique

Non-symmetrical vortex beam shaping in VECSEL laser arrays

We propose and numerically test a novel concept for asymmetric vortex beam generation in a Degenerate Vertical External Cavity Surface Emitting Laser (DVECSEL). The method is based on a phase-locking ring array of lasers created inside a degenerate…
