All that is (nano)gold is not biochemically stable

Researchers stumble upon the lesson that typically stable gold nanoparticles can't always be trusted.

Electric polarization in the macroscopic world and electrons moving at atomic scales

Femtosecond x-ray experiments in combination with a new theoretical approach establish a direct connection between electric properties in the macroscopic world and electron motions on the time and length scale of atoms. The results open a new route for understanding and tailoring the properties of ferroelectric materials.
