Atomic force microscopy on fibers

Natural and synthetic fibers exhibit a huge diversity regarding their dimension, structure and physical-chemical properties. The wanted properties of textiles are adjusted by directed selection, development and processing of fiber material. Atomic force microscopy offers as sole method the possibility to acquire quantitative information in the nanoand micro range under environmental conditions ...

Gum Tragacanth Fibers Introducing Primitive GT Fibers (RESEARCH NOTE)

In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

FABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS

Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...

The other side of kinetochore fibers

The other side of kinetochore fibers n page 671, Khodjakov et al. uncover a new mechanism of spindle morphogenesis that involves the capture of microtubule minus ends. In the established model of spindle formation in vertebrate cells, spindle microtubule minus ends are focused at spindle poles in association with centrosome-nucleated microtubules. Kinetochore O fibers, which pull chromosomes to...
