‘Spindoctors’ note that topological order, associated with quantum mechanics, also applies to classical material called artificial spin ice. Physicists have identified a new state of matter whose structural order operates by rules more aligned with quantum mechanics than standard thermodynamic theory. In a classical material called artificial spin ice, which in certain phases appears disordered, the material is actually ordered, but in a “topological” form.

“Our research shows for the first time that classical systems such as artificial spin ice can be designed to demonstrate topological ordered phases, which previously have been found only in quantum conditions,” said Los Alamos National Laboratory physicist Cristiano Nisoli...

New holographic data storage medium could enable wearable technology that captures and stores detailed 3D images. New nanoparticle-based films that are more than 80 times thinner than a human hair may provide materials that can holographically archive more than 1,000 times more data than a DVD in a 10-by-10-centimeter piece of film...

Engineers at MIT have developed a polymer thermal conductor — a plastic material that, however counterintuitively, works as a heat conductor, dissipating heat rather than insulating it. Image: Chelsea Turner/MIT

Technique could prevent overheating of laptops, mobile phones, and other electronics. Plastics are excellent insulators, meaning they can efficiently trap heat – a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic casings for laptops and mobile phones, which can overheat, in part because the coverings trap the heat that the devices produce.

Now a team of engineers at MIT has developed a polymer thermal conductor – a plastic material that, however counterintuitively, works as a heat co...

These schematics show the printing of water in oil using a nanoparticle supersoap. Gold nanoparticles in the water combine with polymer ligands in the oil to form an elastic film (nanoparticle supersoap) at the interface, locking the structure in place. Credit: Berkeley Lab

Reconfigurable material could be used for liquid electronics and chemical synthesis, among other applications. Scientists from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a way to print 3D structures composed entirely of liquids. Using a modified 3D printer, they injected threads of water into silicone oil – sculpting tubes made of one liquid within another liquid.

They envision their all-liquid material could be used to construct liquid electronics that power flexible,...
