Chemistry
When you stretch your spider silk, it becomes stronger by aligning the protein chains.
Scanning electron microscope images of fibers from engineered spider silk. To verify their calculations, a team in the northwest used spectroscopic techniques to examine how protein chains stretched and aligned with the actual fibers of engineered spider silk. Credit: Washington University, St. Louis As the spider rotates the net, it uses its hind legs to pull the silk thread from…

Researchers outperform silkworm silk by taking a holistic approach
PhD candidates Martin Zaki and Ben Alladeis are exhibiting unlaminated silk fibers and fabrics created at IFM Lab. Photo: Freyla Ferguson / IFM Dr. Ben Aladdis and PhD Deakin’s Institute for Frontier Materials (IFM) candidate Martin Zaki provided the world’s first in research into next-generation materials. Silkworm silk is a protein-based fiber with mechanical properties comparable to synthetic petroleum-derived fibers,…
