Histochemical and morphological characterization of reticular fibers

Histochemistry, 1980
The results presented in this paper show that collagen fibers can be clearly distinguished from reticular fibers using the picrosirius-polarization method. A morphologic and morphometric study of these two types of fibers with electron microscopy shows that reticular fibers are characterized by the smaller diameter of their fibrillar components and the

The morphology of electrospun polystyrene fibers

Korean Journal of Chemical Engineering, 2005
Electrospinning is a process of electrostatic fiber formation which uses electrical forces to produce polymer nanofibers from polymer solution. The electrospinning system consists of a syringe feeder system, a collector system, and a high power supplier.

Polyimide fibers: Structure and morphology

Journal of Applied Polymer Science, 1979
AbstractPolyimide fibers were prepared by wet spinning of poly(p,p′ ‐diaminodiphenylmethanepyro‐mellitamic acid). Density measurements and x‐ray diffraction studies were carried out to study the structure of the resultant polyimide fibers. Polyamic acid as well as undrawn polyimide fibers were essentially amorphous with two amorphous haloes.

Morphological Aspects of Dietary Fibers in the Intestine

1982
Publisher Summary This chapter discusses the morphological aspects of dietary fibers in the intestine. It presents the results from a comparative assessment of the structural responses to the inclusion of carefully defined semi purified fibers and bile salt-binding resins in paired groups of animals.

Morphology of oriented carbon fibers

Carbon, 1975
Abstract Longitudinal microtome sections were obtained from two specimens of PAN-based commercial carbon fibers using three different cutting directions with respect to the fiber axis orientation. Evidence is presented that secondary features larger than the graphite fibril (i.e.

Structure and Morphology of Helicene Fibers

Journal of the American Chemical Society, 1998
Nonracemic helicene 1 when cooled from the melt organizes itself into macroscopic liquid crystalline fibers. Transmission electron microscopic analysis shows that the fibers are comprised of lamellae 50−200 nm wide, each only ca. 10 nm high. Analyses by X-ray and electron diffraction demonstrate that the molecules are organized in hexagonally packed ...
