Plasma-activated polymer films for mesenchymal stem cell differentiation [PDF]

, 2014
Polyetheretherketone (PEEK) is a biomaterial utilized for spine, orthopedic and trauma implants. Its inertness prevents osseointegration, so that coatings with titanium or hydroxyapatite are required for load-bearing PEEK implants.

Peeking at the Impossible

Notre Dame Journal of Formal Logic, 1997
In `On the cohomology of impossible figures' [Topologie Struct. 17, 11-16 (1991; Zbl 0743.52002)] \textit{R. Penrose} provides a mathematical analysis of certain geometrically impossible objects. Essentially, they are those whose parts cannot be consistently assembled, as is expressed by the failure of certain equations to have solutions.
