Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

The rotation impact of the Earth on the parameters trajectory movement of the objects

Military Technical Collection, 2017
The quantitative impact of Coriolis forces on parameters of trajectory movement when shooting plane coincides with the plane of the meridian was calculated in the work. All calculations were carried out using mathematical package MAPLE. The main factors that influence on the trajectory of motion to the movement were determined. Graphic dependences that
