A quantum magnet with a topological twist

Materials with a kagome lattice pattern exhibit 'negative magnetism' and long-sought 'flat-band' electrons.

Understanding high efficiency of deep ultraviolet LEDs

Steps that form during LED fabrication improve their efficiency by creating tiny paths of electric current.

Magnetization reversal achieved at room temperature using only an electric field

Scientists achieved magnetization reversal in cobalt-substituted bismuth ferrite by applying only an electric field. Such an effect had been sought after for over a decade in order to make new types of low-power-consumption magnetic memory devices.

A tip for future nanoscale sensing

The tiny diamond pyramid tips used for atomic force microscopy may also prove to be highly useful for nanoscale, quantum sensing.

With nanopore sensing, physicists detect subtle changes in single particles

The researchers' findings open the door to observe all kinds of interesting phenomenon on nanosurfaces, an area of great interest to chemists.

More flexible nanomaterials can make fuel cell cars cheaper

A new method of increasing the reactivity of ultrathin nanosheets, just a few atoms thick, can someday make fuel cells for hydrogen cars cheaper.

Design principles for disease-sensing nanomaterials

The detailed findings in a new paper could lead to more precise, effective methods of treating and diagnosing a variety of diseases, including cancers.
