At the beginning of the new decade, all data acquisition and analysis systems developed by the PP&B IT group will be compatible with the "bluesky" framework. This software was developed at NSLS-II and is another collaborative development in the EPICS [1] environment. more

Frances Ross has been awarded with the Gerhard Ertl Lecture Award 2019 for her groundbreaking research in electron microscopy that she applies to studying mechanisms of self-assembly and growth of nanostructures on surfaces as well as their manipulation. more

The chemist Prof. Dr. Kevin Pagel has been awarded a highly endowed Consolidator Grant from the European Research Council (ERC). Pagel is a professor of bioorganic chemistry at Freie Universität Berlin and a visiting researcher at the Fritz Haber Institute. more

Researchers from the Fritz-Haber Institute of the Max-Planck Society in Berlin identified aluminum monofluoride (AlF) as an excellent molecule to be laser-cooled to ultra-low temperatures with a high density. Atoms have been laser-cooled with great success for over 30 years. Recently, this powerful technique has been extended to small molecules, but a major challenge remains: to increase the density of the laser-cooled molecular gas by many orders of magnitude. AlF has the potential to achieve this, and recent developments in laser technology now make it possible to use this molecule. AlF is stable and deeply-bound with unique properties, enabling cooling to very low temperatures and with a high density. more

We propose a novel direct detection concept to search for dark matter with masses in the 100 keV to 100 MeV range, in which the dark matter particles scatter off molecules in a gas and excite a vibrational and rotational state of the molecule. The excited ro-vibrational mode relaxes rapidly and produces a spectacular signal consisting of multiple infrared photons, which can be observed with ultrasensitive photodetectors. more

Highly-selective Cu-based catalysts for CO2 electroreduction were synthesized using electrolyte-induced nanostructuring of a Cu foil. In addition to enhanced surface roughness, the effect is associated with the formation and stability of Cu+ species as revealed by operando spectroscopy. more

In the nanometer length-scale, structural stability is prone to ultrafast motions that range from atomic vibrations to translations and rotations of entire nanostructures. To study the rotational motions of entire nanoparticles, we establish femtosecond electron diffraction as goniometer of ultrafast nanocrystal rotations. To achieve our scope we have combined experiments that use ultrashort pulses of electrons and photons, with detailed simulations of molecular dynamics and electron diffraction. more
