Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films ...
Chemists at Kiel University built the first artificial molecular machines that performs synthesis
Chemists usually synthesize molecules using stochastic bond-forming collisions of the reactant molecules in solution. Nature follows a different strategy in biochemical synthesis. The majority of biochemical reactions are driven by machine-type protein complexes that bind and position the ...
Research team of material scientists present an innovative, sustainable energy storage concept
Longer lifetimes, larger ranges and faster recharging - developments such as electric mobility or the miniaturisation of electronics place new requirements on rechargeable batteries. With its enormous storage capacity, silicon has decisive advantages over the materials used in commercially ...
New approach for prevention of biofouling
Organisms like algae, mussels or barnacles rapidly colonise surfaces in maritime applications, such as ship hulls. The protective coatings primarily used to date contain substances like copper, which are harmful to the environment. The nets used in fish farming are also largely impregnated with ...
Research team examines ultrafast conversion of light energy in a solid
During the conversion of light into electricity, such as in solar cells, a large part of the input light energy is lost. This is due to the behaviour of electrons inside of materials. If light hits a material, it stimulates electrons energetically for a fraction of a second, before they pass the ...
Research team investigates the surface chemistry of the frog sticky-tongue mechanism
Frogs' capture their preywiththestickymucuscoveringtheir tongues, but this mucusisn't inherently adhesive.Frogmucus is thought to be pressure-sensitive, with tongue retraction strain triggering adhesion. A research team from Oregan State University, Aarhus University and Kiel University ...
The properties of materials are determined by their atomic structure. If atoms and electrons change their positions, then the characteristics of a material also change. The complex processes that occur during these changes are being investigated by a working group at Kiel University (CAU), using ...
In batteries, fuel cells or technical coatings, central chemical processes take place on the surface of electrodes which are in contact with liquids. During these processes, atoms move over the surface, but how this exactly happens has hardly been researched. Physicists at Kiel University want to ...
Prototype for new connection technology
Welding is still the standard technique for joining metals. However, this laborious process carried out at high temperatures is not suitable for all applications. Now, a research team from the "Functional Nanomaterials" working group at Kiel University, together with the company Phi-Stone AG from ...
Waste heat from industry can often not be utilised because of its low temperature. With this material, it can be used in environmentally friendly cooling systems for example in the field of building technology. The research team from Kiel will present its material and its applications at the ...
