biomimetics materials nacre strong tough

Nacre, also known as mother of pearl, is an organic-inorganic composite material produced by some molluscs as an inner shell layer. It comprises 95% calcium carbonate (aragonite) which, due to its layered microstructure, yields tensile strength, toughness and ductility levels as well as barrier and durability characteristics that far exceed those of monolithic aragonite or artificial inorganic materials such as concrete. 
     The superior engineering properties of nacre result from its controlled microstructure fored during a biomineralization process. This process involves controlled through-solution crystallization of amorphous materials (mostly calcium carbonate) to form intricate microstructures tailored towards serving structural, protective and other purposes.
     Can we learn from biomineralization of nacre to produce improved material for construction of longer-lasting, safer and more sustainable infrastructure systems?All Rights Reserved

Season 4 of The Virus Within Trinity is familiar with zombies, being one herself, but when strange zombies start appearing, she realizes that the world she knew might be changing yet again. When a dangerous set of scientific notes are discovered, Trinity and her friends don't realize anything is wrong until a frantic radio call comes in. Unaware of the notes, they race to the south and struggle to determine where the strange zombies came from. The zombies are unlike any ranks previously seen, and they aren't as predictable. Some have new tricks hidden up sleeves, forcing any Stronghold they encounter to quickly adapt to the new challenge or risk being overrun. Secrets never remain hidden, and zombie apocalypses never make life easy.
