The electrons of an atom located the furthest distance from its nucleus in the highest energy occupied atomic orbitals, are known as the valence electrons of an atom. From the row (period) and group (column) position of a chemical element in the periodic table, y...

In a predefined porosity, the interfiber fusion enhanced the stiffness of the mat by 60%, which is independent of the loading mode and the mechanical property of individual fibers. For all ranges of porosities, bonding increases the stiffness of the mat; however, the bonding is more effective...
The following results were obtained.1. The shear bond strengths of SB to the tested materials were in the range of 27.8-39.8 MPa, nearly equivalent to those of SB to human enamel (39.0 MPa).2. The shear bond strengths of RMGIC to the tested materials were in the range of 0.1-13.9 ...
