In Situ and Step-Heating Ar/Ar Dating of White Mica in Low-Temperature Shear Zones (Tenda Massif, Alpine Corsica, France).

In order to clarify the link between Ar/Ar record in white mica and deformation, we performed in situ and bulkwise Ar/Ar dating over the East Tenda Shear Zone (Tenda massif, Alpine Corsica). White micas from 11 samples were selected and extensively analyzed using in situ techniques across nested scales of strain-intensity gradients developed at the expense of a late-Variscan protolith. Ar/Ar systematics are unaffected by inherited Ar and directly linked to deformation with little or no Ar lattice (volume) diffusion.

Revealing a decades-old fingermark with cyanoacrylate fuming and rhodamine 6G.

Cyanoacrylate fuming, rhodamine 6G staining and 532 nm laser light visualization were used to reveal a thirty-year-old fingermark on a plastic bag discovered at a double homicide scene.

Simulated infrared spectra of triflic acid during proton dissociation.

Vibrational analysis of triflic acid (TfOH) at different water uptakes was conducted. This molecule mimics the sulfonate end of the Nafion side-chain. As the proton leaves the sulfonic acid group, structural changes within the Nafion side-chain take place.
