A bond-order-bond-length-bond-strength (bond-OLS) correlation mechanism is presented for consistent insight into the origin of the shape-and-size dependence of a nanosolid, aiming to provide guidelines for designing nanomaterials with desired functions. It is proposed that the coordination number im...
Relationship between bond-strength tests and clinical outcomesBond strengthClinical effectivenessClinical trialRetentionAdhesiveOne often alleges that laboratory bond-strength testing cannot predict clinical effectiveness of adhesives. Major argument to sustain this claim is the wide variation in bond-strength ...
The strain introduced into intramolecular H-bonds can act to raise the proton transfer barrier. Nonetheless, the relationship between weaker H-bonds and lower barriers is apparent, even in excited electronic states. 展开 DOI: 10.1016/0166-1280(94)80118-5 被引量: 14 ...
The relationship between dentin permeability and the shear bond strength of Scotchbond/Silux was investigated. In the presence of a smear layer, there was no correlation between dentin permeability and dentin bond strengths. After removal of the smear layer with acids, there was an inverse relations...
2.To join (two or more individuals) in a relationship, as by shared belief or experience:An interest in banking reform bonded the two political opponents. 3. a.To finance by issuing bonds:Two projects have already been bonded. b.To raise by issuing bonds:The city bonded $900,000 for th...
Further investigation of the topological properties of the charge density indicates that the generalization of the bond-length-bond-order relationship of CC bonds due to Bader et al. may be extended to intermolecular hydrogen bonding. Calculations at the 6–31G ** level, including complete geometry...
