Scientists show how originally spherical nucleus can transform into cube with high surface-to-volume ratio. These nanocubes are available to be used in practice, and may interest many designers of new materials.
The world is run by catalysts. They clean up after cars, help make fertilizers, and could be the key to better hydrogen fuel. Now, a team of chemists has found a better way to make metal nanoframe catalysts.
Researchers have designed a high-performance nanowire photodetector with side-gated structure by combining ferroelectric materials and nanowires, and the as-fabricated device can be employed to reduce the dark current and increase the sensitivity of the photodetectors.
Using coherent X-rays, a new technique has been discovered for sensing motion and velocity of small groups of atoms. This advance gives an unprecedented, nanoscale view of disordered objects as they are being created - like the thin films used to make solar cells and LCD screens.
