(Section 2.7.2), it is possible for chain molecules to form regions in which repeat units are aligned in close-packed, ordered arrays.Crystalline regionsin polymers are generally lamellar in form and often small, with their smallest dimension in the order of 10–20 nm. Inevitably, because of...
Another example of a molecule containing a 3-electron bond, in addition to two 2-electron bonds, is nitric oxide, NO. The oxygen molecule, O2 can also be regarded as having two 3-electron bonds and one 2-electron bond, which accounts for its paramagnetism and its formal bond order of 2...
OBJECTIVE: To review the development history, chemical composition, bonding mechanism, clinical indications and the differences between Super-Bond C&B and other conventional resin cements, in order to help the clinicians to choose the appropriate bonding system in cementation process of complex cases of...
Surface preparation for ceramic substrates Even though ceramic substrates have high surface energy and can be easily wet, it is important to carry out the necessary surface preparation in order to optimize adhesion to different substrates. Typically, degreasing the substrates would help improve their b...
The bond distance/bond order/bond energy relationships are surveyed for various bond types. The ionic model is applied to the crystal lattice energy calculations, introducing Madelung's constants. Electronic properties of solids, particularly band gaps, are related to the type of the chemical bonding...

While similar to the phenolic bond, a polyimide resin is a stronger, higher-temperature binder that requires less volume in order to bond the superabrasive material. This allows the polyimide resin to be combined with a wide variety of other materials to make the wheel structure more heat-conduc...
For example, in order to form covalent bonds in graphene (nanotubes and fullerenes), one of the 2s electrons is promoted to a 2p orbital, and the orbitals are then hybridised to form what are called sp2 bonds. In sp2 bonding, each carbon atom forms three bonds with three other ...
