A new twist in eutectic composition: deracemization of a racemic compound amino acid by Viedma ripening and temperature fluctuation. [PDF]
, 2021 Viedma ripening and temperature fluctuation are processes based on solution phase racemization and dissolution-growth of racemic or scalemic conglomerates resulting in solid-phase deracemization.

Enabling direct preferential crystallization in a stable racemic compound system [PDF]
, 2019 The preparative resolution by preferential crystallization (PC) of proxyphylline has been achieved despite the existence of a stable racemic compound. This is enabled through the careful selection of a solvent in which both the racemic compound and the ...

Crystal structure of β-d,l-allose
Acta Crystallographica Section E: Crystallographic Communications, 2015 The title compound, C6H12O6, a C-3 position epimer of glucose, was crystallized from an equimolar mixture of d- and l-allose. It was confirmed that d-allose (l-allose) formed β-pyranose with a 4C1 (1C4) conformation in the crystal.
