- Efficient photocathode for generating hydrogen using sunlight
A team at the HZB Institute for Solar Fuels has developed a new composite photocathode for generating hydrogen with high quantum efficiency using sunlight. This enables solar energy to be stored ch... - Bonding behaviour of iron pentacarbonyl experimentally decoded
Following six years' work, an international team comprising eleven research institutions has been successful in observing precisely how light affects the outer electrons of a metallic compound and ... - Losing one electron switches magnetism on in dichromium
An international team of scientists from Berlin, Freiburg and Fukuoka has provided the first direct experimental insight into the secret quantum life of dichromium. Whereas in its normal state the ... - Holes in valence bands of nanodiamonds discovered
Researchers hope that their properties might be altered to permit nanodiamonds to be used as catalysts for generating hydrogen from sunlight. Nanodiamonds are tiny crystals only a few nanometres... - Artificial catalysts imitate natural photo-synthesis
Scientists at the Helmholtz Center for Materials and Energy (HZB) in collaboration with the School of Chemistry and ARC Centre of Excellence for Electromaterials Science at Monash University, Austr...
- New in situ cell for investigating solid- and liquid-state samples and their interfaces under electrical voltage
A team headed by Dr. Kathrin Aziz-Lange has developed a new in-situ cell for X-ray spectroscopy of fluid samples and their interfaces to solid bodies. What is special is the cell contains electrode... - Better knowledge on interpretation of RIXS-spcetra
RIXS-spectroscopy is a powerful method to gain insights into molecular and electronic structures in complex samples, liquid or solid. HZB scientists now know even a bit better how to interpret the ... - Lighter elements precisely detected using scanning electron microscopy
Reflection zone plates produced by HZB enable lighter elements in material samples to be efficiently and precisely detected using scanning electron microscopy (SEM) by providing high resolution in ... - New class of protein crystals discovered
Scientists at the Helmholtz Center Berlin (HZB) along with researchers at China's Fudan University have characterized a new class of materials called protein crystalline frameworks (PCFs). Thank... - New kind of spectrometer for the analyses of sample surfaces
HZB's own Prof. Dr. Gregor Schiwietz and his team have developed a new kind of spectrometer capable of particularly sensitive analyses of sample surfaces. It has allowed them to be the first to obt... - Three-dimensional volume diffraction optics for X-rays developed
Physicists at HZB have developed a process to generate improved lenses for X-ray microscopy that provide both better resolution and higher throughput. To accomplish this, they fabricate three-dimen... - X-ray pulses on demand from Electron Storage Rings
HZB physicists recently devised a new method to pick single x-ray pulses out of the pulse trains usually emitted from synchrotron radiation facilities. The technique is very useful to support studi... - New tool for Joint Lab to investigate the chemistry of nature
The Aziz' team at the Joint Laboratory between Freie Universität Berlin and HZB has built a laser-based tabletop setup which generates ultrashort XUV light pulses and achieves their monochromatizat... - Even thinner solar cells through use of nanoparticles
Nanostructures could enable more light to be directed into the active layer of solar cells, increasing their efficiency. Prof. Martina Schmid (HZB und Freie Univ. Berlin) has now measured how irreg... - Aging of Li-ion batteries explained by using X-ray absorption spectroscopy
Even the best Li-ion batteries degrade with time. A reason for this was now identified by researchers at HZB. They could directly observe at BESSY II and DORIS atomic rearrangements occurring in th... - How to use light to manipulate the spin in topological insulators
Researchers at HZB investigated the topological insulator bismuth selenide (Bi2Se3) by spin-resolved photoelectron spectroscopy at BESSY II. They found an astonishing difference depending on whethe... - Analysis of the efficiency of solar cells by time-resolved spectroscopy
Perovskite based solar cells are a hot topic in energy research and Science Magazine has put it on the list of Breakthroughs in 2013. In only a few years their efficiency has increased from 3 % to ...
- Better insight into molecular interactions
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...
- Imaging with neutrons: Magnetic domains shown for the first time in 3D
So far, it has only been possible to image magnetic domains in two dimensions. Now, for the first time, Scientists at Helmholtz-Zentrum Berlin (HZB) have managed to create three-dimensional images ... - New microscope reveals ultrastructure of cells
Researchers at Helmholtz-Zentrum Berlin (HZB) have developed a new X-ray nanotomography microscope. Using their new system, they can reveal the structures on the smallest components of mammalian ce... - Innovative measuring chamber for X-ray study of liquid jets
Until now, the only way to study liquids by soft X-ray emission spectroscopy (XES) has been through a membrane window. Now, researchers of Helmholtz-Zentrum Berlin have carried out an XES study of ...
