Nanoscale 3D quantitative imaging of 1.88 Ga Gunflint microfossils reveals novel insights into taphonomic and biogenic characters

Precambrian cellular remains frequently have simple morphologies, micrometric dimensions and are poorly preserved, imposing severe analytical and interpretational challenges, especially for irrefutable attestations of biogenicity. The 1.88 Ga…

Kinetic study of azobenzene E/Z isomerization using ion mobility-mass spectrometry and liquid chromatography-UV detection

Z and E azobenzene isomers are molecular switches which can interconvert both photochemically and thermally. Presently, we studied a ketal-substituted bridged azobenzene in which two stable diastereomeric conformers (Z1 and Z2) photochemically…

Fluorescent Copolymers for Bacterial Bioimaging and Viability Detection

Novel fluorescent labels with high photostability and high biocompatibility are required for microbiological imaging and detection. Here, we present a green fluorescent polymer chain (GFPC), designed to be nontoxic and water-soluble, for multicolor…

Naviguer dans la toile : imagerie 3D de textiles minéralisés du site de Nausharo (première moitié du IIIe millénaire av. J.-C.)

Les textiles sont périssables dans la plupart des environnements archéologiques. L’un des principaux processus conduisant à la préservation exceptionnelle de leur morphologie résulte du contact avec un objet métallique, un phénomène connu sous le…

Unravelling the true MOF-5 luminescence

Highly pure millimeter-sized MOF-5 single crystals were synthesized and characterized. Photoluminescence (PL) spectroscopy and time-correlated single photon counting (TCSPC) demonstrate a solvent-guest dependency of MOF-5 emission and its ligand…

Helically shaped cation receptor: design, synthesis, characterisation and first application to ion transport

The methyl ester of 8-oxo-8H-indenonaphtho[1,2-b]thiophene-2-carboxylic acid (1) and its corresponding PEGylated ester were synthesised and fully characterised. X-ray diffraction studies on (1) confirmed the helical structure of the receptor and…
