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.

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.

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.
