Better insight into molecular interactions

23-Aug-2013

How exactly atoms and molecules in biochemical solutions or at solid-liquid interfaces do interact, is a question of great importance. Answers will provide insights at processes in catalysts, smart functional materials and even physiological processes in the body, which are essential for health. ...

Open a door for solid state physics

Laser processes observed with X-rays on a solid

23-Aug-2013

Without the currently available plethora of X-ray methods, basic research in the physical sciences would be unthinkable. The methods are used in solid state physics, in the analysis of biological structures, and even art historians have X-rays to thank for many new insights. Now, scientists at ...

Fast detector for a wide wavelength range

13-Aug-2013

Free-electron lasers are extremely versatile research tools because their intense, super short light flashes permit a closer look at new materials and even biological molecules; thus, allowing effects to be observed that had not been known previously. For pulsed lasers in the far infrared range, ...

Watching catalysts at work -- at the atomic scale

Innovative combination of methods at HZB leads to fundamental insights in catalyst research

29-Jul-2013

Scientists of Helmholtz-Zentrum Berlin (HZB) and collaborators have now combined the spectroscopic method "RIXS" with so-called ab initio theory in order to describe these processes in detail for a model organometallic catalyst of great interest to catalysis research – the iron carbonyl complex. ...

Luminous bacterial proteins detect chemicals in water

13-Jun-2013

While residual medications don’t belong in the water, trace metals from industrial process waters handled by the recycling industry are, in contrast, valuable resources. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a simple color sensor principle which facilitates ...

American biochemist to receive this year's Inhoffen Medal

12-Apr-2013

How do bacteria cope when exposed to toxic mercury, how are they able to outlast antibiotics, and how can they be killed using so-called "suicide inhibitors?" These are but a few of the many research topics US biochemist Christopher Walsh has devoted his career as a scientist to. Walsh will be ...

Magnetic fingerprints of interface defects in silicon solar cells detected

02-Apr-2013

In theory, silicon-based solar cells are capable of converting up to 30 percent of sunlight to electricity - although, in reality, the different kinds of loss mechanisms ensure that even under ideal lab conditions it does not exceed 25 %. Advanced heterojunction cells shall affront this problem: ...
