Other Morphologies

The structures discussed above are just examples that can be found in mar synthetic fibers. Fiber scientists now can manipulate the fiber formation processes to obtain a wide range of stractures for different applications. Therefore, other crystalline morphologies and models exist for synthetic fibers.

The tables show that the fronds treated with extracted materials exhibited bleaching, chlorosis, and other morphological changes. 

Even more complex structures have been described. For example, chirality of blocks may lead to other morphologies. A polystyrene-fc-poly-(L-lactide) diblock copolymer, PS-fr-PLLA, constituting both achiral and chiral blocks was reported to form an array of hexagonally packed PLLA nanohelices with a left-handed helical sense in the bulk state (Fig. 3). The structure was found... 

In contrast to the other, morphologically relevant photoreceptor phytochrome, no unequivocal assay is available for the bluelight photoreceptor. This makes its purification and molecular characterization extremely difficult. 

Finally, the formation of crew-cut micelles with spherical and various other morphologies was reported by Eisenberg and coworkers for PS-PEO diblocks with a major PS block [134], More information about crew-cut micelles will be given in Sect. 6. 

Other morphologies have also been made and observed for SiNW. Although straight nanowires dominate, other forms such as string beans (strings of pearls), shells. 

Patel et al. showed that a Bruggeman exponent of 1.5 is often not valid for real separator materials, which do not have uniform spherical shape.Porous networks based on other morphologies such as oblate (disk-type) ellipsoids or lameller increase the tortuous path for ionic conductivity and result either in a significant increase of the exponent a, or in a complete deviation from the power law. They showed that spherical or slightly prolate ellipsoidal pores should be preferred for separators, as they lead to higher ionic conductivity separators. 

Digital image analysis directly gives the size distributions and a mean diameter, d. All other morphological characteristics are calculated with this mean diameter and the model shown in Fig. 20. 

The particles formed are in most cases spherical, although rods, ellipsoids, platelets, and hexagonal structures have also been produced. Solids composed of spherical particles are as a rule amorphous, while those of other morphologies are crystalline. In general, aging times of 2 h at approximately 100°C were sufficient to produce the desired results however, in some instances much longer times were necessary to complete the precipitation process. 

Chronic use of combination agents depresses ovarian function. Follicular development is minimal, and corpora lutea, larger follicles, stromal edema, and other morphologic features normally seen in ovulating women are absent. The ovaries usually become smaller even when enlarged before therapy. 

The use of shape-symmetry arid other morphological features in the study of the internal structure of crystals will be considered further in Part 2 of this book (Chapters VII and VIII). Here we are concerned with crystal shapes in so far as they afford evidence for the purpose of identification. 

Before leaving the subject of crystal shape, there are a few other morphological features which are sometimes encountered and must be mentioned briefly. 

The domain spacing and interfacial area per block were determined for blends of PS-PI diblocks in PS for a < 1 using SAXS by Hashimoto et al (1990). The domain spacing was found to increase with increasing homopolymer volume fraction, as depicted in Fig. 6.7 for blends of a diblock forming a lamellar phase in the melt. Addition of homopolymer leads to transitions to other morphologies... 

In addition to chlorophyll mutations, other morphologic and physiologic characteristics have been used in mutational studies in plants.70 109 Two characteristics that have... 

While other plant studies were conducted relative to other morphological observations and interactions with exogenously applied plant growth regulators such as indole-3-acetic acid and abscisic acid, the major message was that CB influenced cytoplasmic streaming, but not cell division perse, in plants.
