Skyrmions are stable topological vortices in the magnetization. They can be created on surfaces of magnetic materials where they move through the materiallike a kind of hose. Their motion can be controlled with magnetic and/or electric fields or currents. Skyrmions have a diameter in the nm range and can be easily generated and also detected. SkyrMem is a novel storage arrangement that uses these properties of the skyrmions. It consists of a strip of magnetic material, about twice as wide as the diameter of a skyrmion. A potential barrier is applied in the center of the strip so that the skyrmions can only be placed above or below the line. This can be used to represent logical “1” and “0”. By applying a voltage, the scyrmions can be moved along the strip, permitting serial reading of the information.
With SkyrMem, a completely new type of digital memory can be realized. Since scyrmions are very small and nevertheless stable, storage densities above the values customary today for hard disks are possible. High readout rates can also be achieved. SkyrMem provides a technical basis for the storage media of the future.
A German patent application was filed, international applications are still possible.
In the name of the University of Cologne, we offer interested companies the opportunity to license and further develop the technology.
Powered, multi-funcitonal limb movement auxiliary method and device, particularly prosthesis and movement-assisting orthosis, with combined estimation regimes of multiple degrees of freedom (DOF) showing a “natural” movement.
Diazadiborines provide a new class of substances for molecular electronics. In addition to the application in the area of molecular electronics itself, i.e. as molecular electronic building blocks, diazadiborines may also ? analogously to other polycyclic aromatic compounds ? be used in the area of printable electronics, esp. as functional compounds in printing-pastes
The first inorganic compound with a double helix structure is a semiconductor with interesting mechanical properties.
Scientists at RWTH Aachen University developed a novel screening method substantially improving the finding of favored enzyme variants using the directed evolution technique. The method, an entirely cell-free system, uses innovative compartments, thus enabling the efficient detection of human and toxic proteins.
