'Resonance' raman spectroscopy with 1-nm resolution

06-Sep-2019

Tip-enhanced Raman spectroscopy resolved "resonance" Raman scattering with 1-nm resolution in ultrathin zinc oxide films epitaxially grown on a single-crystal silver surface. Tip-enhanced "resonance" Raman scattering can be used to investigate a specific chemical structure at nanoscale and at the ...

Scientists demonstrate the wavelike nature of van der Waals Forces

14-Mar-2016

Like the gravitational forces that are responsible for the attraction between the Earth and the moon as well as the dynamics of the entire solar system, there exist attractive forces between objects at the nanoscale. These are the so-called van der Waals forces, which are ubiquitous in nature and ...

X-ray laser reveals chemical reaction

18-Mar-2013

What happens when a chemical bond is broken? That question was recently answered with the help of a so-called free electron x-ray laser, which makes it possible to follow in real time how bindings in a molecule are changed and broken. The study, published in Science, found, among other things, ...

Insights into the process which converts carbon dioxide into methanol could make it possible to recycle greenhouse gas

02-May-2012

There is now one less mystery in chemical production plants. For many decades industry has been producing methanol on a large scale from a mixture of carbon dioxide and carbon monoxide, as well as hydrogen. An international team, including chemists from the Fritz Haber Institute of the Max Planck ...
