In this work, we have performed a detailed investigation on the crystallization tendency of the modeled glass-forming pharmaceutical compound, fenofibrate. To do this, we have employed four different experimental techniques allowing following of the crystallization process. This has included...

Why is surface diffusion the same in ultrastable, ordinary, aged, and ultrathin molecular glasses?.

Physical chemistry chemical physics : PCCP

Ngai KL, Paluch M, Rodríguez-Tinoco C.
PMID: 29086788
Phys Chem Chem Phys. 2017 Nov 15;19(44):29905-29912. doi: 10.1039/c7cp05357f.

Recently Fakhraai and coworkers measured surface diffusion in ultrastable glass produced by vapor deposition, ordinary glass with and without physical aging, and ultrathin films of the same molecular glass-former, N,N'-bis(3-methylphenyl)-N,N'-diphenylbenzidine (TPD). Diffusion on the surfaces of all these glasses...
