Synergy in a superlattice

Article Abstract:

Researchers have achieved the synergistic combination of two materials' properties in one superlattice, where the material is an example of binary nanocrystal superlattice that could be used as a thermoelectric. Lead telluride and silver telluride are used as the nanocrystal building-blocks, where the addition of silver telluride provides silver ions as dopants, thus improving the material's overall electrical conductivity and its thermoelectric figure of merit.

Changing face of the chameleon

Article Abstract:

The chameleon compounds can be crystalline or amorphous, metallic or semi conducting and conductors of ions or electrons, which are already important in optical storage discs and fibres, are being proposed as the basis for sold-state memory technologies. This thermally driven, amorphous-crystalline phase change, which can encode binary information, is already of great commercial significance.

Don't mention the 'F' word: Raising brows

Article Abstract:

The US president funded femtotechnology was expected to lead advances in medicines, information technology, and defense. The first picobot clones were built in order to assemble themselves into cell parts required to make animal muscle tissue but it eventually resulted in extinction of animals, thereby infuriating the president.
