The flexural strength of bonded ice [PDF]
The Cryosphere, 2020 Abstract. The flexural strength of ice surfaces bonded by freezing, termed freeze bond, was studied by performing four-point bending tests of bonded freshwater S2 columnar-grained ice samples in the laboratory. The samples were prepared by milling the surfaces of two ice pieces, wetting two of the surfaces with water of varying salinity, bringing these

The Microtensile Strength of Bonding Resins [PDF]
Australian Dental Journal, 2001 AbstractBackground: The purpose of this study was to determine the effect of water on the tensile strength of three bonding resins (All Bond 2, Scotchbond Multi‐Purpose Adhesive, Clearfil LB Bond) and a low viscosity resin composite (Protect Liner F) after 1, 7, 28, 84 and 168 days of storage.Methods: Cylinders of bonding resin 2.4±0.2mm diameter and 9.

Bond Strengths of Two Dental Bonding Systems [PDF]
Military Medicine, 2000 A new bonding system named Kevloc has been introduced. It is based on acrylization of the metal surface with the goal of preventing the occurrence of a marginal gap between the metal and the resin. The purpose of this investigation was to determine the values of the shear bond strength achieved using the Kevloc technique on Ag-Pd (Auropal SE) and Co-Cr

Bond strength of brackets bonded with an adhesion promoter [PDF]
British Dental Journal, 2004 Enhance-L.C. is an orthodontic adhesion promoter. Our aim was to find out if this product is material-specific as stated by its manufacturers or whether its effects are similar when the promoter is used with other adhesive systems.In vitro study.Dental Clinic. University of Murcia, Spain, 2002.Enhance-L.C.

Strength of a bifurcated H bond [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Hydrogen bonding is one of the characteristic features of macromolecules. Therefore, it is not surprising that extensive research has gone into understanding the energetics and importance of hydrogen bonding. All of these studies focused on hydrogen bonds that involve a single donor and acceptor pair.

Bond strength evaluation of the veneering-ceramics bonds [PDF]
Medicina Oral Patología Oral y Cirugia Bucal, 2010 The purpose of this study was to determine whether the bond of veneering porcelain to a ceramic core in bilayered ceramics was similar to that of the metal ceramic control of well known behaviour.Six groups of nine specimens each were fabricated, whose dimensions were 15 mm long and 8 mm in diameter at the core, and 2 mm long and 8 mm in diameter for ...

The strength of a chemical bond [PDF]
International Journal of Quantum Chemistry, 2021 AbstractWe discuss the physical criteria that have been proposed as a measure of the strength of a chemical bond. Critical examination of the strengths and weaknesses of the various quantities shows that the force constant is the most general measure for determining the strength of a chemical bond in molecules.

New Way for Probing Bond Strength [PDF]
The Journal of Physical Chemistry A, 2020 The covalent chemical bond is intimately linked to electron sharing between atoms. The recent independent gradient model (IGM) and its δg descriptor provide a way to quantify locally this electron density interpenetration from wavefunction calculations. Each bond has its own IGM-δgpair signature. The present work establishes for the first time a strong
