Scientists uncover a process that stands in the way of making quantum dots brighter

Bright semiconductor nanocrystals known as quantum dots give QLED TV screens their vibrant colors. But attempts to increase the intensity of that light generate heat instead, reducing the dots’ light-producing efficiency. A new study explains why,...

First closeups of how a lithium-metal electrode ages

They discovered that the nature of the battery electrolyte, which carries charge between the electrodes, has a big impact on aging – a factor that needs to be taken into account when developing electrolytes that maximize a battery’s performance.

A new hands-off probe uses light to explore the subtleties of electron behavior in a topological insulator

Topological insulators are electron are superhighways on their edges and insulators everywhere else. Researchers used a process called high harmonic generation to separately probe electron behavior in both of those domains.

Squeezing a rock-star material could make it stable enough for solar cells

A promising lead halide perovskite is great at converting sunlight to electricity, but it breaks down at room temperature. Now scientists have discovered how to stabilize it with pressure from a diamond anvil cell. The required pressure is well...

Study shows tweaking one layer of atoms on a catalyst’s surface can make it work better

When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately engineering the surface to take advantage of this...
