This is neat stuff yet I am having trouble with the use of the term &quot;material&quot;, somebody help me.<p>To me this isn&#x27;t a new material any more than aluminum honeycomb is a new material.  The material is aluminum or steel.  They are then fabricated into honeycomb sheets or lattices.<p>I don&#x27;t see it as discovering a new material but rather fabricating an existing material in a different way.<p>Other examples of this might be aluminum truss used in staging and the use of trussed steel in bridge building.<p>What is a material?
