77Se Solid-State NMR Investigation of Selenium Chemical Shift Tensors of Chalcogen Bonds in Selenadiazole Cocrystals

Tristan Axel Georges

This study focuses on 3,4-dicyano-1,2,5-selenadiazole and substituted 2,1,3-benzoselenadiazole-based cocrystals synthesized via mechanochemical methods and characterized by a combination of X-ray diffraction and solid-state NMR spectroscopy. Eight new sing ...

Millisecond-time-scale Controlled Freeze-quench for Solute-intermediate Analysis by Solid-state Nmr

Tristan Axel Georges

Crystallization is a fundamental process in biomineralization, yet its complexity increases significantly in non-classical pathways of nucleation and growth, where numerous intermediates exist between free ions in solution and the final crystalline phase. ...

43ca Freeze-quenched Mas-dnp for the Characterization of Transient Phases Involved in Nonclassical Formation of Hydroxyapatite

Tristan Axel Georges

Calcium orthophosphates, such as hydroxyapatite (HAP), have been shown to follow nonclassical nucleation and crystallization mechanisms involving intermediate species, including solute prenucleation species (PNS) that precede solid transient phases. Charac ...
