Access to new fluorescent materials
Access to new fluorescent materials
Significantly increased efficiency of fluorescence - Wide range of applications in everyday life Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important role in our everyday lives, for example in modern screens.

Honeycombs in the desert
Honeycombs in the desert
Convection of salty water creates hexagonal patterns The honeycomb-like patterns that often occur in salt deserts, including Death Valley and Chile, look like something from another world. A team that included researchers from the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany, explain the origin of the mysterious patterns for the first time.

When the light is neither 'on' nor 'off' in the nanoworld
When the light is neither ’on’ nor ’off’ in the nanoworld
Scientists at the Universities of Würzburg and Bielefeld detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips. Whether the light in our living spaces is on or off can be regulated in everyday life simply by reaching for the light switch.

Method found for analysing complex, tiny crystals
Method found for analysing complex, tiny crystals
The atomic structure of solid substances can often be analysed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances exist. Chemist Professor Oliver Oeckler from Leipzig University and his team are developing methods to make this possible even for very small crystals that cannot be seen with the naked eye.

Method found for analyzing complicated, tiny crystals
Success after ten years of research: Three intergrown compounds discovered The atomic structure of solid substances can often be analyzed quickly, easily and very precisely using X-rays. However, this requires that crystals of the corresponding substances are available. Chemist Oliver Oeckler of the University of Leipzig and his team are developing methods to make this possible even for very small crystals that are invisible to the naked eye.

Creating 3D objects with sound
Scientists assemble matter in 3D using sound waves for 3D printing Scientists from the Max Planck Institute for Medical Research and the Heidelberg University have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed.

New method for targeted design of molecules
New method for targeted design of molecules
Potential applications include industrial processes, drug discovery and optoelectronics Engineering novel molecules and materials with specific properties can yield significant advances for industrial processes, drug discovery and optoelectronics. However, the search for novel molecules and materials is comparable to looking for a needle in a haystack, since the number of molecules in chemical space is of the unimaginable order of 10 to the power of 60.

Asteroid impact in slow motion
Asteroid impact in slow motion
For the first time, researchers have recorded live and in atomic detail what happens to the material in an asteroid impact. The team of Falko Langenhorst from the University of Jena and Hanns-Peter Liermann from DESY simulated an asteroid impact with the mineral quartz in the lab and pursued it in slow motion in a diamond anvil cell, while monitoring it with DESY's X-ray source PETRA III.

Thermal motions and oscillation modes determine the uptake of bacteria in cells
Thermal motions and oscillation modes determine the uptake of bacteria in cells
Team at the University of Freiburg analyzes how model bacteria dock to and penetrate membrane bubbles. How and with what effort does a bacterium - or a virus - enter a cell and cause an infection? Researchers from Freiburg have now made an important contribution to answering this question: A team led by physicist Alexander Rohrbach and his collaborator Dr. Yareni Ayala was able to show how thermal fluctuations of a model bacterium and membrane oscillation modes of a model cell influence the energy with which the model bacteria dock and enter the membrane.

Colour images from the shadow of a sample
Researchers at Göttingen University develop new method for X-ray colour imaging A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan the whole sample.

A new model for dark matter
A new model for dark matter
PRESS AND PUBLIC RELATIONS Phase transition in the early universe changes strength of interaction between dark and normal matter Dark matter remains one of the greatest mysteries of modern physics. It is clear that it must exist, because without dark matter, for example, the motion of galaxies cannot be explained.

Physical effect also valid in the quantum world
Researchers at the University of Bonn confirm validity of a central theorem of physics for Bose-Einstein condensates Physicists at the University of Bonn have experimentally proven that an important theorem of statistical physics applies to so-called "Bose-Einstein condensates." Their results now make it possible to measure certain properties of the quantum "superparticles" and deduce system characteristics that would otherwise be difficult to observe.

Swarm Intelligence Caused by Physical Mechanisms
Seemingly spontaneously coordinated swarm behaviour exhibited by large groups of animals is a fascinating and striking collective phenomenon. Experiments conducted by researchers at Leipzig University on laser-controlled synthetic microswimmers now show that supposed swarm intelligence can sometimes also be the result of simple and generic physical mechanisms.
