Winding borders may enhance graphene
Far from being a defect, a winding thread of odd rings at the border of two sheets of graphene has qualities that may prove valuable to manufacturers.
Worms lead way to test nanoparticle toxicity
The lowly roundworm is the star of an ambitious Rice University project to measure the toxicity of nanoparticles.
Wrinkle predictions
New mathematical theory may explain patterns in fingerprints, raisins, and microlenses.
Microscopic monitoring may yield advances in production of products, pharmaceuticals
A team of physicists has developed a method to monitor the properties of microscopic particles as they grow within a chemical reaction vessel, creating new opportunities to improve the quality and consistency of a wide range of industrial and consumer products. Their work offers benefits for commodities ranging from food and pharmaceuticals to perfumes and cosmetics.
Graphene displays clear prospects for flexible electronics
Researchers show that new 2D 'designer materials' can be produced to create flexible, see-through and more efficient electronic devices.
A molecular sensor for 'crowd control' in cells
Scientists have developed a molecular sensor to measure 'crowding' in cells, which reflects the concentration of macromolecules present. The sensor provides quantitative information on the concentration of macromolecules in bacteria and in mammalian cells.
Dance of the nanovortices
The trajectories of small magnetic entities referred to as skyrmions have been captured and recorded with the help of X-ray holography. Researchers gained new insight from the analysis of this motion: these nanoscale vortices possess mass.
The quest for efficiency in thermoelectric nanowires
Researchers say better materials and manufacturing techniques for the nanowires could allow carmakers to harvest power from the heat wasted by exhaust systems or lead to more efficient devices to cool computer chips.
