Mechanochemical Defluorination of Polytetrafluoroethylene (PTFE) With Base Metals

Angewandte Chemie, EarlyView.
Polytetrafluoroethylene (PTFE) mechanochemically reacts with safe‐to‐handle, abundant, and inexpensive base metals Zn and Al, as well as with metals like Cd and Pb, to produce sp2‐carbon and industrially important metal fluorides. The reactivity presents PTFE as a mechanochemical fluorination agent, with opportunities for closed‐loop reductive ...

Nanoporous tantalum coated zirconia implant improves osseointegration

, 2020
Zirconia has become a new dental implant material because of its excellent esthetics, biocompatibility, and minimal ion release. However, biological inertness of zirconia surface results in weak integration with bone tissue in the early stage of ...
