Effect of different surface treatments on the shear bond strength of nanofilled composite repairs

open access: yesJournal of Dental Research, Dental Clinics, Dental Prospects, 2016
Background. Repairing aged composite resin is a challenging process. Many surface treatment options have been proposed to this end. This study evaluated the effect of different surface treatments on the shear bond strength (SBS) of nano-filled composite ...

Hydrogen bond dynamics at the glass transition [PDF]

open access: yesarXiv, 2021
The glass transition in hydrogen-bonded glass formers differs from the glass transition in other glass formers. The Eshelby rearrangements of the highly viscous flow are superimposed by strongly asymmetric hydrogen bond rupture processes, responsible for the excess wing.

Comparison of shear bond strength of the stainless steel metallic brackets bonded by three bonding systems [PDF]

open access: yesCaspian journal of dental research, 2013
Introduction: In orthodontic treatment, it is essential to establish a satisfactory bond between enamel and bracket. After the self-etch primers (SEPs) were introduced for the facilitation of bracket bonding in comparison to the conventional etch-and ...

Insights into the fracture mechanisms and strength of amorphous and nanocomposite carbon [PDF]

open access: yesPhys. Rev. Lett., 96, 185503 (2006), 2006
Tight-binding molecular dynamics simulations shed light into the fracture mechanisms and the ideal strength of tetrahedral amorphous carbon and of nanocomposite carbon containing diamond crystallites, two of the hardest materials. It is found that fracture in the nanocomposites, under tensile or shear load, occurs inter-grain and so their ideal ...
