Tubercles are much more than amorphous lumps of corrosion product and deposit. They are highly structured. Structure and growth are interrelated in complex ways.

In addition to examining the structure and growth of thin passivating oxide films, the process of film reduction and breakdown promises to be a fruitful area of research. Some preliminary results involving SECM as well as STM have been published [257,270,271].

Ikemiya et al. [445] have investigated both the atomic structure and growth of electrodeposited Te films on Au(lOO) and Au(lll) with large lattice misfits. Deposition was performed in sulfuric acid solutions using in situ AFM. On both substrates, bulk-deposited Te films were formed according to the Stranski-Krastanov mechanism. Their atomic structures changed with the increasing film thickness. 

Of the morphological phenomena mentioned in the last few paragraphs, that of twinning is likely to be of most frequent value in identification problems, but all the phenomena are significant from the point of view of crystal structure and the relation between internal structure and growth characteristics. The subject of crystal morphology in relation to internal structure will not, however, be pursued further at present it will be taken up again in Chapters VII and VIII. For the present, we shall continue our consideration of the problem of the identification of microscopic crystals we pass oij to discuss crystal optics, the relation between optical properties and crystal shape and symmetry, and the determination of refractive indices and other optical characteristics under the microscope.

The entire animal or plant is composed either of cells or of substances thrown off by cells cells have a life that is somewhat independent, and litis individual life of all the cells is subject to that of the organism as a whole. ... 

The purpose of this paper is to summarize the current understanding of the defect chemistry of nonlinear optical oxide crystals and specifically the relationship of the defects present to 1) the structure and growth, or processing, of the material and 2) the properties of interest for device applications. The defects in traditional nonlinear optical oxide crystals (i.e. BaTiC>3, LiNbC>3, Sri-xBaxNb206, Ba2NaNb50l5, K3Li2Nb50l5) are reviewed. Our recent work on the defect chemistry of new...

Instead of supramolecular synthons, in nucleation work it is more common to talk about a growth unit defined as the es-sential building block that transfers structural information from the solution to the crystal surface. The relationship between supramolecular synthons, which come from observation of complete crystal structures, and growth units, is at present poorly understood. 

One of the key discoveries was the realization that very many real networks in nature, technology (e.g., the Internet and WWW) and human relations have similar structure and growth patterns, and can be described by the same mathematical formulas. All of them share similar properties and behavior. This discovery and the new theory have created an unprecedented opportunity for investigating resilience and vulnerabilities of the Internet and the WWW. For this reason we consider the scale-free network theory and related empirical results as being a significant development in the Cyberspace Security and Defense. 

Compound 14, having the structural and growth-promoting characteristics expected of a potential anticytokinin, was tested for its ability to block the promotion of cell division and growth by other compounds having significant cytokinin activity.

Hydrogen permeation tests on ferritic stainless steels indicated that hydrogen can diffuse through the alloys, though the permeation was drastically decreased by formation of chromia scale on the alloys. - The mechanisms by which the presence of hydrogen or protons at the air side affects the oxide scale structure and growth are not clearly understood at this time. Several mechanisms have been proposed to tentatively explain the observed anomalous oxidation behavior. ...

Because each monomer is potentially tetrafunctional, all sorts of partially hydrolyzed and partially condensed species are possible. For example, 10 distinct dimers may be formed. Many cyclic species can occur. Many of the species in solution are metastable with respect to anhydrous, amorphous Si02, and rearrangements occur with time (2). The complexity of this system means that the structure and growth of these polymers can be described only in a statistical and geometric fashion rather than by a more conventional description in terms of topologies (such as chains and cross-links) and molecular weights. The most useful and intuitive description of the structure of these polymers is in terms of fractal geometry.
