[structure: see text] Non-aldol aldol rearrangement of the epoxy silyl ether 13b afforded the expected anti methyl ketone 14, while the diastereomeric epoxy silyl ether 13a afforded the syn methyl ketone 8b via an unprecedented syn hydride migration. Calculations suggest that this unusual reaction proceeds via the carbocation, which cannot easily rotate due to steric hindrance.

Non-isothermal crystallization kinetics has been traditionally predicted using the Nakamura crystal growth model, which is an integral form of Avrami equation under assumption that non-isothermal can be explained a series infinitesimal isothermal steps. However, model often overpredicts fraction near end because ignoring slower secondary kinetics. In this study, dual proposed to capture both pr...

Poly‐ether‐ether‐ketone (PEEK) is a biocompatible, high‐strength polymer with biomechanical properties similar to soft bone that has been proposed as an alternative titanium for orthopedic implants. Herein, micro‐CT imaging of 3D printed PEEK scaffold treated plasma immersion ion implantation (PIII) assess the degree osteoconduction relative identical untreated structure, by in scapula sheep, p...
