• 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 f more

• Wiggling atoms switch the electric polarization of crystals
  

  Ferroelectric crystals display a macroscopic electric polarization, a superposition of many dipoles at the atomic scale which originate from spatially separated electrons and atomic nuclei. The macroscopic polarization is expected to change when the atoms are set in motion but the connection between more

• Reducing manure and fertilizers decreases atmospheric fine particles
  

  Fine particulates have numerous sources – not only traffic, which is currently under particular scrutiny. Reducing agricultural emissions could also considerably reduce the particulate levels that are hazardous to health, concludes a study by researchers at the Max Planck Institute for Chemistry in more
