Generating energy from fluctuations of light

Researchers at the Laboratory of Organic Electronics at Linköping University have developed a method and a material that generate an electrical impulse when the light fluctuates from sunshine to shade and vice versa. As ...

Tetrahedrality is key to the uniqueness of water

A Japan-based research team has studied the anomalous behavior of tetrahedral liquids such as water. Via computer simulation, they calculated the phase diagrams of a range of model liquids. Varying a parameter called lambda ...

Better identification of microscopic fossils

Blue-green algae are one of the oldest organisms in the world and have an important role to play in many ecosystems on Earth. However, it has always been difficult to identify fossils as blue-green algae without any trace ...

Superconductivity in an alloy with quasicrystal structure

Extraordinary things happen at low temperatures. One of the best examples is superconductivity, a phenomenon wherein the electrical resistance of a solid drops to zero below a critical temperature. Known for a century, superconductivity ...

Smart conveyor rollers to optimize parcel logistics operations

Engineers from Saarbrücken have developed a system of self-monitoring conveyor rollers to solve crucial logistics problems for sorting offices and parcel services. Drive systems specialist Professor Matthias Nienhaus from ...
