New view of dendrites in Li batteries gets to the root of the problem
Muscles act as metamaterials due to collective behavior, physicists show
Sodium-air battery offers rechargeable advantages compared to Li-air batteries
Ferroelectric memristors may lead to brain-like computers
Solution-grown nanowires make the best lasers
Take a material that is a focus of interest in the quest for advanced solar cells. Discover a "freshman chemistry level" technique for growing that material into high-efficiency, ultra-small lasers. The result, ...
Prototype 'nanoneedles' generate new blood vessels in mice
Scientists have developed tiny 'nanoneedles' that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice.
Landmark study proves that magnets can control heat and sound
Researchers at The Ohio State University have discovered how to control heat with a magnetic field.
Popular origami pattern makes the mechanical switch
An origami paper-folding pattern called the square twist is the basis of a microscopic switch that Cornell physicists say could lead to origami-inspired materials and machines.
Wrinkle predictions: New mathematical theory may explain patterns in fingerprints, raisins, and microlenses
As a grape slowly dries and shrivels, its surface creases, ultimately taking on the wrinkled form of a raisin. Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. ...
Graphene displays clear prospects for flexible electronics
Published in the scientific journal Nature Materials, University of Manchester and University of Sheffield researchers show that new 2D 'designer materials' can be produced to create flexible, see-through and mo ...
How ionic: Scaffolding is in charge of calcium carbonate crystals
Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic scaffolds in which such crystals form guide crystallization ...
Solar cell polymers with multiplied electrical output
One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy ...
World's most complex crystal simulated
The most complicated crystal structure ever produced in a computer simulation has been achieved by researchers at the University of Michigan. They say the findings help demonstrate how complexity can emerge ...
First direct evidence that a mysterious phase of matter competes with high-temperature superconductivity
(Phys.org)—Scientists have found the first direct evidence that a mysterious phase of matter known as the "pseudogap" competes with high-temperature superconductivity, robbing it of electrons that otherwise ...
