Thermoelectric materials can be much more efficient

Researchers from the University of Twente's MESA+ research institute have managed to significantly improve the efficiency of a thermoelectric material. Because of their unique qualities, these materials can convert waste ...

First thin films of spin ice reveal cold secrets

Thin films of spin ice have been shown to demonstrate surprising properties which could help in the development of applications of magnetricity, the magnetic equivalent of electricity.

Imaging ferroelectric domains

(Phys.org) —When thin films of ferroelectric materials are grown on single-crystal substrates, they can develop regions of aligned polarization—called "domains"—that often adopt complex patterns. Manipulation of ferroelectric ...

Atomic-scale catalysts may produce cheap hydrogen

Researchers at North Carolina State University have shown that a one-atom thick film of molybdenum sulfide (MoS2) may work as an effective catalyst for creating hydrogen. The work opens a new door for the production of cheap ...

'Inverse opal' structure improves thin-film solar cells

(Phys.org) —Researchers have shown how to increase the efficiency of thin-film solar cells, a technology that could bring low-cost solar energy. The approach uses 3-D "photonic crystals" to absorb more sunlight than conventional ...
