Biomimicry
=== Battery Electrodes === Crab shells which already have the bouligand structure, can be used as templates for nanostructred battery electrodes. Crab shells are a low-cost, sustainable alternative to otherwise expensive starting materials and processing methods for nanostructures batteries. The crab shells have a Bouligand structre composed of highly-mineralized chitin fibers. The structure can be used as a bio-template to make hollow carbon nanofibers. The desired battery materials, often sulfur and silicon, can be contained in these hollow fibers to create the cathodes and anodes.


 * I want to add more here about why nanostructured batteries are good

=== Nanocellulose Films === Cellulose nanocrystals self assemble into helicoldical thin flims, the pitch angle between the layers can then be modified via solvent processing. The resulting nanocellulose films, which have a Bouligand structure, can be manipulated to achive various effects on the material properties. These nanocellulose films are impact-resistant, sustainible, and multi-functional and can be used in various applications such as: stretchable electronics, protective coatings, eyewear, and body armor.

Shear wave filtering
The periodic and hierarchical nature of the Bouligand structure, creates a shear wave filtering effect that is especially effective during high intensity dynamic loads. As the force is applied, specific frequencies that are in shear are not permitted to transmit through the layered structure, creating a band gap in the transmitted energies and decreasing the effective energy felt by the system. The pitch angle of the layers, thickness of the layers, and number of layers present in the material all effect which frequencies are filtered out.

This section will focus on the biomimetic applications of the bouligand structure. Some possible subjects to cover include:


 * Plywood Structure
 * Something that would go into the main section
 * Bio templating
 * Could potentially add this as a section?
 * Crab shells used as templates for battery electrodes
 * Nanocellulose films made with a bouiligand structure
 * Biomimetic nanocomposites
 * This aticle is really just all about aditive manufacturing methods

The section will go over some of these examples and why the bouligand structure is beneficial. The methods used to create the biomimetic materials will also be discussed. The different examples will most likely be separated into a few smaller subsections.
