The strength of a chemical bond [PDF]

open access: yesInternational 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.

Bond Strength of Fusion Bonded Epoxy-Coated Reinforcement in Concrete

open access: yesJournal of the Civil Engineering Forum, 2019
Fusion-bonded epoxy-coated steel is expected to extend the service life of the reinforced concrete structure in chloride-laden environments. However, the effect of coating on the bond-strength between rebar and concrete is not well understood yet.

The influence of bond-rigidity and cluster diffusion on the self-diffusion of hard spheres with square-well interaction [PDF]

open access: yes, 2007
Hard spheres interacting through a square-well potential were simulated using two different methods: Brownian Cluster Dynamics (BCD) and Event Driven Brownian Dynamics (EDBD). The structure of the equilibrium states obtained by both methods were compared

Kuat Rekat Tarik dan Geser Bahan Bonding pada Perekatan Awal Braket dengan Pengetsaan dan Perekatan Ulang Tanpa Pengetsaan

open access: yesJournal of Dentistry Indonesia, 2015
The incidence of loose brackets during orthodontic treatment has reached 5%; therefore, loose brackts should be rebonded. Rebonding without etching might decrease chair time without compromising bond strength.
