The Morphological Structure

Numerous works have been implemented on tellurium electrochemistry and its adsorption at metal surfaces. The morphological structures of electrodeposited Te layers at various stages of deposition (first UPD, second UPD, and bulk deposition) are now well known [88-93]. As discussed in the previous paragraphs, Stickney and co-workers have carried out detailed characterizations of the first Te monolayer on Au single-crystal surfaces in order to establish the method of electrochemical atomic layer epitaxy of CdTe. 

First of all let us consider the morphological structure of an agglomerate electrode [6] by way of example of the model shown in Figure 1. This schematic represents a multiphase system with no fixed connection between its components. As a rule, the active mass of an electrode is a mixture of Nickel hydroxide (oxyhydroxide) with conductive carbon or a metal, which are well dispersed mechanically in the matrix. 

The morphological structure of irradiated cells was also significantly injured all membrane structures melted and became less contrast, organelles, especially nuclei, were round off, condensed, and fragmented - a typical picture of toxic stress (Fig. 7.4). 

The biocrystalline layer of avian egg shells is approximately 270-300 jum thick (chicken). It can be divided into morphological units as follows eisospherites, organic matrix core, zone of tabular aggregates, zone fish bone patterns, external zone, cuticle, and organic matrix. Details of the morphological structure have been reviewed recently28, 374). 

Electron microscopy (59, 60) is not as generally applicable because sample preparation is sometimes difficult. For the butadiene-styrene copolymers used here, contrasting of the butadiene phase with 0s04 is particularly suitable (41). Thin films, several tenths of a micron thick, are cast from dilute solutions and placed in the vapor of an aqueous 0s04 solution. A similar process is followed for thin sections of macroscopic samples. If the morphological structure of these films in planes normal to the film surface is of interest, such films must be embedded before cutting in a material of similar hardness which does not swell or dissolve the sample to be investigated. 

Between February 1999 and July 2001, a total number of 96 patients (52 females, 44 males mean age 31 years), suffering from nasal hyperreactivity symptoms, were enrolled from those attending our ENT Department. Inclusion and exclusion criteria were evaluated examining the description of clinical signs and symptoms, the morphological structure of nasal cavities, and causal factors. 

The signs and symptoms considered were rhinorrhea, nasal obstruction and sneezing. The morphological structure of the nasal cavities was examined with anterior rhinoscopy. Skin prick tests, nasal provocation tests, nasal microbiological tests and mucociliary clearance time (MCT) were used to identify the causal factors. The skin prick tests were used to... 

The morphological structure of the fiber determines the pathway that dyes take during dyeing and is critical for the rate and extent of dye uptake. In some way, the dye has to penetrate the more or less hydrophobic layer on the fiber surface, formed by the epicuticle and the exocuticle. The strong swelling capacity of the intercellular cement is important for the penetration of dyes into the fiber. Only then are the sulfur-rich keratins also penetrated by the dye molecules. In general terms, Fick s law can be applied to the diffusion phenomena [46],... 

What role does the cooling rate play in the morphological structure of semi-crystalline polymers ... 

The phase equilibrium of materials is an inherently multiscale phenomenon which spans from the functional group (or atomic) scale through the morphological-structure scale to the macroscopic scale. Two texts presented in this volume are devoted to this problem. 

It is interesting to note that the (L-N-B)-model leads to similar expressions for the moduli like the VTG-model apart from the first summand of Eq. (38). However, contrary to the semi-empirical weighting functions W(y6) of the VTG-model, the corresponding density distribution function/la(y) in the (L-N-B)-model is related to the morphological structure of the filler network, i.e., the distribution of singly connected bonds in a percolation network. Unfortunately, this distribution function is not known, exactly. Therefore, a simple exponential... 

The morphological structure of precipitates can often be improved by after-treatment. It is known that the solubility of very small particles is considerably greater than that of a larger crystal of the same substance. If a mixture made of the mother liquor and the precipitate is simply allowed to stand for a longer time, the small particles will slowly dissolve in the mother liquor, while the larger particles will in turn grow thus a recrystallization occurs. This process...
