This bismuth-III structure is also observed for antimony from 10 to 28 GPa and for bismuth from 2.8 to 8 GPa. At even higher pressures antimony and bismuth adopt the body-centered cubic packing of spheres which is typical for metals. Bi-III has a peculiar incommensurate composite crystal structure. It can be described by two intergrown partial structures that are not compatible metrically with one another (Fig. 11.11). The partial structure 1 consists of square antiprisms which share faces along c and which are connected by tetrahedral building blocks. The partial structure 2 forms linear chains of atoms that run along c in the midst of the square antiprisms. In addition, to compensate for the... 

An important feature of surfactant monolayers is their transferability from the air-water interface to clean, smooth, solid supports such as glass or metal surfaces. Blodgett and Langmuir (67) developed this technique and employed it for building up multilayers whose thickness was that of a known number of molecular chain lengths. Recently, there has been considerable interest in the application of this technique to prepare organized multilayers for the study of optical, electrical, and catalytic properties of very thin films of known composition (47,53-55). 

The composition of branched building blocks in the isolated clusters of the amylose-free potato starch, was analyzed by treating the clusters with excess a-amylase (Bertoft, 2007b). Under such conditions, the enzyme is forced to continue the attack at internal chains shorter than 9 residues inside the clusters. As a resultthe building blocks, which practically resist further attack... 

The shape of the rate-time plot is significant a maximum in rate suggests a chain reaction. Build-up to a maximum corresponds to build-up to the steady state, after which the concentration of chain carriers remains constant and the overall rate, a composite quantity, gradually decreases as in a typical non-chain reaction. When there is a complex mechanism the overall rate constant is also composite and is made up of one or more rate constants relating to individual steps in the mechanism e.g. in Chapter 3, Problem 3.18, the mechanism for the decomposition of C3H8 is a chain mechanism and the analysis gave...
