Recognition of unmyelinated fiber disease: Morphologic criteria
Muscle & Nerve, 1978AbstractAn attempt is made to evaluate available information regarding the integrity of unmyelinated fibers, particularly somatic unmyelinated fibers in man and in other primates, with relation to early recognition of nerve disorders. Discussion is limited to morphologic aspects of these fibers.

Structure and Morphology of Helicene Fibers
Journal of the American Chemical Society, 1998Nonracemic 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 ...

Mechanical properties and micro-morphology of fiber posts
Dental Materials, 2013To evaluate flexural properties of different fiber posts systems and to morphologically characterize their micro-structure.Six types of translucent fiber posts were selected: RelyX Post (3M ESPE), ParaPost Taper Lux (Colthéne-Whaledent), GC Fiber Post (GC), LuxaPost (DMG), FRC Postec Plus (Ivoclar-Vivadent), D.T. Light-Post (RTD).

Morphological study on poly‐p‐phenylenebenzobisoxazole (PBO) fiber
Journal of Polymer Science Part B: Polymer Physics, 1998Morphological survey on new PBO fiber (Zylon®) was conducted by X-ray and transmission electron microscopic studies. Crystal size, orientation of the crystal, fibrils, microvoids, and fine structure were discussed. It was found that the molecule in the fiber showed high orientation (more than 0.99 in Hermann's orientation function for heat-treated ...

Morphological Aspects of Dietary Fibers in the Intestine
1982Publisher 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.

Formation of high‐performance fiber morphologies
Journal of Applied Polymer Science, 1980AbstractProcesses aimed at forming high‐performance fiber morphologies from rigid, semirigid, and flexible polymers have been analyzed. Routes that rely at least partially on the favorable thermodynamic consequences of conformational rigidity imparted by intramolecular and polymer–solvent interactions are shown to offer much greater promise than those ...

Fiber Orientation and Fracture Morphology in Short Fiber-Reinforced Thermoplastics
1989Spatial fiber distribution and fracture morphology were studied for three injection-molded thermoplastic composites: PPS, PAI, and PEEK reinforced with carbon fibers. Specimens were dog bone-shaped tensile coupons and flex bars. Both optical and scanning electron microscopes were used.
