The predominantly deep-sea hexactinellid sponges are known for their ability to construct remarkably complex skeletons from amorphous hydrated silica. The skeletal system of one such species of sponge, Euplectella aspergillum , consists of a square-grid-like architecture overlaid with a double set of diagonal bracings, creating a chequerboard-like pattern of open and closed cells. Here, using a combination of finite element simulations and mechanical tests on 3D-printed specimens of different… Expand

Extreme flow simulations reveal skeletal adaptations of deep-sea sponges.
TLDR
Mechanisms of extraordinary adaptation to live in the abyss are revealed, paving the way towards further studies of this type at the intersection between fluid mechanics, organism biology and functional ecology. Expand

TLDR
By comparing the disordered sponge ridge geometry to other more symmetrical strake-based vortex suppression systems commonly employed in infrastructure applications ranging from antennas to underwater gas and oil pipelines, it is found that the unique maze-like ridge organization of E. aspergillum can completely suppress vortex shedding rather than delaying their shedding to a more downstream location, thus highlighting their potential benefit in these engineering contexts.

3D-Printed Architected Materials Inspired by Cubic Bravais Lattices.
TLDR
This study aims to provide a deeper understanding of the structure-property relationship of crystal-lattice-inspired materials, starting from the study of single unit cells inspired by the cubic Bravais crystal lattices, and suggests that the chosen topologies have a mainly stretching-dominated behavior.

Exploring the property space of periodic cellular structures based on crystal networks
TLDR
It is shown that molecular crystal networks with atoms connected by chemical bonds can be interpreted as cellular structures with nodes connected by mechanical bars and identified new structures with extremal properties as well as known structures such as the octet-truss or the Kelvin cell and how crystallographic symmetries are related to their mechanical properties.
