The European Research Council awards the ERC Starting Grant for top-level early-career scientists to Ellen Backus, who is working at the MPI-P. The physical chemist will receive funds for her scientific work amounting to 1.5 million euros for the next five years.
To do this she uses laser pulses to cause a vibration of the molecules, and then she measures the resonance of the molecular vibration. This allows conclusions to be drawn about the dynamics and interaction of the molecules. In a second step, a further laser pulse takes over the sun’s task: It splits the water molecules.
The pulses are comparable to the flashes of a stroboscope, but with durations of femtoseconds, which are 10-15 of a second. With these ultra-short time intervals it is now possible to sequentially record how the molecules move on the one hand and how they split on the other.
The photocatalytic splitting of water has great potential to produce hydrogen in an ecological and economic way. As previously forecasted, hydrogen as a source of energy will play a decisive role for covering energy requirements in future; however fewer losses have to be achieved during the reaction for it to become economical. Ellen Backus’ scientific work is concentrated on the fundamental processes that occur during splitting in order to understand the energy transport, and the molecules’ bond behavior.ERC Starting Grants are among the most prestigious grants awarded by the European Research Council for world-class researchers. They give the opportunity for top-level early-career scientists to conduct fundamental research and establish or consolidate their own research team. According to the ERC, last year, 500 research scientists and their projects were funded with a total of about 800 million euros.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
