The hardness and strength of alloys can be explained in terms of bonding. The impurity atoms added may form localized and rigid bonds. These tend to prevent the slippage of atoms past each other, which results in a loss of malleability and an increase in hardness. 

When solvent welding or thermal welding is not practical or desired, adhesive systems can be used. Adhesive types such as epoxies, urethanes, thermosetting acrylics, nitrile phe-nolics, and cyanoacrylates permit ABS to be bonded to itself and to other substrates. The best adhesives have shown strength greater than that of ABS however, these adhesives provide very rigid bonds. 

The particles in a solid are held together with sufficient force to maintain a rigid structure. In some cases, these forces consist of intermolecular forces, while in others, chemical bonds. Solids are typically classified according to the types of forces that hold the particles together. When classified this way, the four types of solid are molecular, ionic, covalent network, and metallic. 

These and other hydrogen bonds and hydrophobic interactions at the northern end of the molecule around the copper site make this the most rigid part of the molecule. This particularly applies to azurin, auracyanin, and rusticyanin, with the most buried copper sites and least to the phytocyanins, where the sites are much more exposed. 

The composition of a cell membrane is not uniform for all types of cells. Some cell membranes are more rigid than others. Rigidity is determined by a variety of factors, one of which is the structure of the carbon chains in the phospholipids that comprise the membrane. One example of a phospholipid was drawn in Section 3.7A, and another, having C-C double bonds in its carbon chains, is drawn here. Which phospholipid would be present in the more rigid cell membrane and why ... 

Occasionally, when the chemical exposure or other environmental considerations have dictated the use of a material that cannot be successfully bonded to the substrate, this same principle has found use even in composite linings employing "acid brick" or other rigid internal facings to protect the membrane lining from thermal or mechanical damage. An application of this kind requires the most careful study and construction if it is to be successful, and should not be attempted without the advice of experienced persons. 

The idea may be extended to other rigid double bond systems such as an imine, R2C=NR, or azo, RN=NR, in which case the terms syn and anti are used instead of cis or trans. 

Figure 18 shows a typical roll fusing configuration (100). A 100>m thick sheet of bond paper, bearing an approximately 30 m thick toner pattern enters the zone between a pair of rolls, one of which is compressible, the other rigid. The hot roll briefly presses the toner into...
