Topological insulators feature lossless conduction at the edges

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...

Study finds electrical fields can throw a curveball

MIT researchers have discovered a phenomenon that could be harnessed to control the movement of tiny particles floating in suspension. This approach, which requires simply applying an external electric field, may ultimately ...

New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...

Watching single protons moving at water-solid interfaces

The H+ proton consists of a single ion of hydrogen, the smallest and lightest of all the chemical elements. These protons occur naturally in water where a tiny proportion of H2O molecules separate spontaneously. Their amount ...

A theoretical boost to nano-scale devices

Semiconductor companies are struggling to develop devices that are mere nanometers in size, and much of the challenge lies in being able to more accurately describe the underlying physics at that nano-scale. But a new computational ...

Physicists offer a new 'spin' on memory

Imagine biting into a peanut butter sandwich and discovering a slice of cheese tucked between the bread and the butter. In a way, this is what happened to a team of physicists at the University of Arizona, except the "cheese" ...

NMR confirms molecular switches retain function in 2-D-array

Researchers led by Jiří Kaleta of IOCB Prague have synthesized regular 2-D assemblies of isotopically labelled molecular switches and measured the properties of their isomerization, revealing that formation of such an assembly ...

Transistor sets a new standard for energy efficiency

Smartphones, laptops and smartwatches consume vast quantities of energy, yet only around half of this energy is actually used to power important functions. And with billions of these devices in use worldwide, a significant ...

Nanofiber membranes transformed into 3-D scaffolds

In the movie "Transformers," cars morph into robots, jets or a variety of machinery. A similar concept inspired a group of researchers to combine gas foaming, which is a blend of chemicals that induces gas bubbling, and 3-D ...

Antiferromagnetic fluoride nanocrystals

When magnetic materials are nanometric at least in one dimension, the surface effect often dominates the static and transport behaviors due to the limited long-range order and broken translation symmetry. The perturbations ...
