Material gradients could strengthen polymer components

via Phys.org

Combining flexible and stiff materials has bestowed bamboo with a strength-to-weight ratio that rivals steel. Gradually transitioning from a soft to hard substance allows the squishy squid to slice up prey with rigid, scissor-like beaks.

With the help of a new  co-developed at the University of Nebraska-Lincoln, these two evolution-honed principles could eventually enable engineers to double or triple the strength of polymer-based components.

LSU Biology Sciences Professor Develops Biodegradable Mardi Gras Beads from Microalgae

BATON ROUGE – Tens of thousands of pounds of plastic Mardi Gras beads enter the environment every year. After the parades, most of the discarded beads end up in the landfill. Biologist Naohiro Kato at LSU is developing an innovative way to solve this problem by creating biodegradable Mardi Gras beads.
