Researchers patent a nanofluid that improves heat conductivity

Scientists have developed and patented a nanofluid improving thermal conductivity at temperatures up to 400 C without assuming an increase in costs or a remodeling of the infrastructure. This progress has important applications in sectors such as chemical, petrochemical and energy, thus becoming a useful technology in all industrial applications using heat transfer systems such as solar power plants, nuclear power plants, combined-cycle power plants and heating, among other.

Restoring order - A spin Hall effect without all the fuss

Scientists have developed a model for what happens when ultracold atomic spins are trapped in an optical lattice structure with a 'double-valley' feature, where the repeating unit resembles the letter W. This new theory result opens up a novel path for generating what's known as the spin Hall effect, an important example of spin-transport.

Goldilocks principle wrong for particle assembly: Too hot and too cold is just right

Micro- and nanoparticles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of scientists has found. Their discovery points to new ways to create 'smart materials', cutting-edge materials that adapt to their environment by taking new forms, and to sharpen the detail of 3-D printing.

Towards controlled dislocations

Scientists have used atomic-resolution Z-contrast imaging and X-ray spectroscopy in a scanning transmission electron microscope to explore dislocations in the binary II-VI semiconductor CdTe, commercially used in thin-film photovoltaics. The results may lead to eventual improvement in the conversion efficiency of CdTe solar cells. These novel insights into atomically resolved chemical structure of dislocations have potential for understanding many more defect-based phenomena.

Nanomaterial boost for stone conservation

Castles and cathedrals, statues and spires - Europe's built environment would not be the same without these witnesses of centuries past. But, eventually, even the hardest stone will crumble. EU-funded researchers have developed innovative nano-materials to improve the preservation of our architectural heritage.
