“It turns out that the fiber is made of a number of nanostrands,” Schniepp ... Consequently, Schniepp said, the silk cross-section is 1/10,000th that of a human hair. Schniepp and Wang also found that ...

In contrast, for common textiles, including silk fabrics, to reach such level ... the air voids cause strong optical scattering in the fiber cross-section, providing sideways confinement of ...

So a cross-section of polar bear hair would show it ... the researchers turned to another natural fiber: silk. Instead of using the silk fiber directly, the silk was purified and dissolved in ...

However, there have also been drawbacks to these techniques, as Jonathan Brewer points out, since they often require cutting the silk thread (also called fiber) open to obtain a cross-section for ...

Although the team identified the fiber’s protein ingredients ... He argued that future experiments should try to directly observe these layers by capturing silk cross-sections using electron ...

Schniepp explained that all species of spiders produce strands of silk that are essentially protein cablets, more or less round in cross section. But the brown recluse ... loops cause premature ...
