Spectroscopic and thermal properties of stannadithiane compounds bearing endocyclic ether and lactone groups
(Pergamon-Elsevier Science Ltd, 2019-03)
Four related stannadithiane compounds containing different endocyclic functional groups -including ether (1), diether (2), lactone (3), and spirolactone (4)- were prepared. The conformational landscape has been fully ...
Effect of cyclic compressive loading on the bond strength of an adhesive system to dentin after collagen removal
(2005-07-25)
Purpose: The objective of this study was to verify the effect of cyclic compressive loading on the shear bond strength of an adhesive system following collagen removal. Materials and Methods: Sixty bovine teeth were divided ...
