Frictionless

Researchers have developed a simple new way to make material surfaces with intricate nanoscale textures, all inspired by nature. Different patterns have a range of applications, like making antimicrobial surfaces or reducing ship hull friction.

As honeybees collect pollen and nectar from flowers, they repeatedly bend and straighten their abdomens – yet with a minimal amount of friction. Scientists have discovered what makes this possible, and it could have applications in human technology.

Researchers at the Karlsruhe Institute of Technology (KIT) have figured out how to potentially use the structure of snake scales to enhance everything from hip prostheses to computer hard disks.

Developed as part of the MAGDRIVE research project, a new frictionless transmission gear and corresponding contactless axles have been created using superconductor magnetic levitation. Aimed primarily for use in spacecraft, the system is also adaptable for use in automobiles, railways, and aircraft.
