Thermoelectrics: From heat to electricity

A lot of heat gets lost during the conversion of energy. Estimates even put it at more than 70%. However, in thermoelectric materials, such as those being studied at the Institute of Solid State Physics at TU Wien, heat can ...

Malaria parasites form vortices

The disease of malaria is triggered by single-celled parasites that accumulate in large groups in the salivary glands of mosquitoes before transmission to human beings. The limited space there prevents them from actually ...

Phase transitions in the early universe and their signals

Phase transitions, such as the boiling of water or the melting of a metal, are commonplace but fascinating phenomena that spur surprises decades after decades. They often occur as the temperature of a substance is changed, ...

A look into the future of magnetic phase transitions

Researchers at PSI have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes. This view into processes that take place within so-called artificial spin ...

Novel theory of entropy may solve materials design issues

A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this phenomenon for some specific ...
