Forces in an optical funnel is selected as Editor's Choice and featured in Physics

11 December 2015

The manipulation of airborne micrometer-size particles by light is governed by photophoresis, a thermal force, which is due to uneven illumination of the particles. The more-illuminated side becomes slightly warmer and the resulting airflow around the particle pushes it away from the intensest light.

Review: Spatially-controlled complex molecules and their applications

06 November 2015

Our review article on spatially-controlled complex molecules and their applications is published in International Reviews in Physical Chemistry. Ee provide an overview of the creation of structurally pure neutral samples in the gas phase using strong inhomogeneous electric fields in the electrostatic deflector — the electric analog of a Stern-Gerlach deflector.

On the road to diffractive imaging of intrinsic molecular dynamics

09 September 2015

The determination of molecular structure and its changes over time is an essential step towards understanding chemical dynamics.
​Time-resolved diffractive imaging is one promising approach to unravel structural changes, of nuclei and electrons, within a molecule. In the Controlled Molecule Imaging (CMI) group at CFEL two complementary diffractive imaging approaches, i.e., x-ray and electron diffraction, are employed to achieve a more complete picture of structural dynamics of gas-phase molecules.

Femtochemistry conference kicks off in Hamburg

13 July 2015

Nobel laureate and femto pioneer Ahmed Zewail holds public scientific lecture — about 400 attendees.
At the 12th International Conference on Femtochemistry FEMTO12 — organizes by the CFEL Controlled Molecule Imaging Group — world leading experts gather at DESY in Hamburg this week. Femtochemistry deals with the ultrafast chemical interactions between molecules and atoms and is of fundamental importance for a broad spectrum of questions in many disciplines, from basic physics to biology and materials science.

What's a "molecular movie"?

04 July 2015

It is a dream of the molecular sciences to record movies of molecules in action, i.e., undergoing chemical reactions, with atomic resolution. These molecular movies would provide a clear, albeit fairly classical, slow-motion movie of the atomic displacements during the chemical rearrangement.
