Reusing waste energy with 2-D electron gas

More than 60 percent of the energy produced by fossil fuels is lost as heat. Thermoelectric energy conversion has attracted much attention as a way to convert waste heat from power plants, factories and cars into electricity. ...

Nature of bonding determines thermal conductivity

Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. ...

Magnetism in thin insulating films at room temperature

(Phys.org)—Researchers at the University of Twente's MESA+ Institute for Nanotechnology have succeeded in producing ultrathin films with an unusual combination of properties. At room temperature they do not conduct electricity, ...

Researchers reveal model of Sun's magnetic field

Researchers at the Universities of Leeds and Chicago have uncovered an important mechanism behind the generation of astrophysical magnetic fields such as that of the Sun.

Making flexible electronics with nanowire networks

A smartphone touchscreen is an impressive piece of technology. It displays information and responds to a user's touch. But as many people know, it's easy to break key elements of the transparent, electrically conductive layers ...
