The Euplectella aspergillum is a cylindrical sponge that lives intropical waters. It has a height of 45 cm. Its exoskeleton consists of hydrated, amorphous silicon dioxide organized into a complexnetwork of spicules that supports the structure. These fibres, whichare 5-10 cm long and as thin as a hair form a crown at the foot ofthe network that anchors the sponge to the bottom of the ocean.

Using design principles inspired by the nanoscopic hairs on the gecko, UC Berkeley researchers and colleagues have created a novel microfiber array which has very high friction but is not “sticky”.

Many processes in organisms based on the self-organization of biological components. For materials scientists, such substances are a dream: you react autonomously to their environment and can adapt to this different conditions. At the U.S. MIT researchers aim to produce such wonders molecules artificially.

Hook and loop fasteners have become commonplace features of both industry and households.
These fasteners are resistant to chemicals and can withstand a tensile load of up to 35 tonnes per square meter at temperatures as high as 800°C.
Metaklett is basically suitable for use in all areas that require easily opened but stable fasteners, for example air-conditioning and ventilation systems in building services engineering and automotive construction.
