Reproducible generation of green-emitting color centers in hBN using oxygen annealing

The ability to generate quantum emitters with reproducible properties in solid-state matrices is crucial for quantum technologies. Here, we show that a high density of close-to-identical single-photon emitters can be created in commercial hexagonal…

Self-assembly dynamics of simple icosahedral nucleocapsids under high and low capsid protein concentrations

All viruses on Earth depend on host cell machinery for replication, a process that entails a complex self-assembly mechanism. The cowpea chlorotic mottle virus (CCMV) is a simple, icosahedral, non-enveloped, single-stranded RNA (ssRNA) plant virus…

Quantifying nucleation in flow by video-FLIM

During a precipitation experiment in microfluidics, crystals appear in the flow. Using a molecule that turns fluorescent in the solid phase, these crystals can be counted, measured and their polymorph identified. From this collection of data, the…

Probing single-molecule dynamics in self-assembling viral nucleocapsids

All viruses on Earth rely on host cell machinery for replication, a process that involves a complex self-assembly mechanism. Our aim here is to scrutinize in real time the growth of icosahedral viral nucleocapsids with single-molecule precision…

Exploring non-Euclidean photonics: Pseudosphere microlaser

Classical and wave properties of microlasers with the shape of a truncated pseudosphere are investigated through experiments and numerical simulations. These pseudosphere microlasers are surface-like organic microlasers with constant negative…

Spectro-FLIM for heritage: scanning and analysis of the time resolved luminescence spectra of a fossil shrimp

Nous décrivons l'utilisation d'un dispositif d'imagerie par comptage de photons uniques pour scanner la surface d'un spécimen fossile plat. Nous avons étudié une crevette du Trias précoce identifiée comme Anisaeger longirostrus, du biote de Paris …

Direct fabrication of rough gold nanoholes and investigation of their second-harmonic generation

Abstract In this study, we introduce a simple and cost-effective technique called one-photon absorption-based direct laser writing (OPA-based DLW) to directly fabricate noncentrosymmetric gold nanoholes (Au NHs). This technique relies on the…
