Bond Strengths:  The Importance of Hyperconjugation

Organic Letters, 2006
[Structure: see text] Gronert (J. Org. Chem. 2006, 71, 1209) has challenged the importance of hyperconjugation in determining C-H bond dissociation enthalpies (BDEs) in alkanes. Electron paramaganetic resonance spectra of H3CCH2*, (H3C)2CH*, and (H3C)3C* show significant positive spin on their beta-H3C groups' hydrogens. A 55%/45% partitioning of these

Bond strength and durability of porcelain bonding systems

The Journal of Prosthetic Dentistry, 1996
Because the most effective bonding system for ceramic restorations has not been documented, this study examined bond strength and durability of bonding systems joined to a feldspathic porcelain. Disks of porcelain specimens were fired on refractory investment materials and were air-abraded with alumina.

Bond strengths of dentine bonding agents to dentine

British Dental Journal, 1992
This study assessed comparatively the tensile bond strengths to dentine of four resin dentine bonding agents. Flat surfaces were produced in the occlusal dentine of human third molars, finished with 600-grit paper and prepared for bonding to Silux Plus composite with Gluma, Prisma Universal Bond 2, Scotchbond 2 and Tenure.

Bond strengths of resin-bonded metal castings

Dental Materials, 1985
Abstract Composite resin-retained appliances are susceptible to failure at the resin-metal interface. The objective of this study was to evaluate bond strengths of perforated and electrolytically etched framework designs by subjecting them to tensile and shear loading. Shear bond strengths were always higher than tensile bond strengths.
