Grasshoppers (Orthoptera)

open access: yes, 2014
Grasshoppers belong to the insect order Orthoptera, which also includes locusts and crickets. This order comprises more than 26,000 species (http://orthoptera.speciesfile.org) with global distribution and higher diversity in the tropics. The name of the order is derived from “orthos,” meaning “straight,” and “pteron,” meaning “wing.” Most orthopteran ...

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
