A dual catalytic strategy for carbon-phosphorus cross-coupling via gold and photoredox catalysis. [PDF]

open access: yes, 2014
A new method for the P-arylation of aryldiazonium salts with H-phosphonates via dual gold and photoredox catalysis is described. The reaction proceeds smoothly at room temperature in the absence of base and/or additives, and offers an efficient approach ...

A Novel Multi-Phosphonate Surface Treatment of Titanium Dental Implants: A Study in Sheep

open access: yesJournal of Functional Biomaterials, 2014
The aim of the present study was to evaluate a new multi-phosphonate surface treatment (SurfLink®) in an unloaded sheep model. Treated implants were compared to control implants in terms of bone to implant contact (BIC), bone formation, and biomechanical
