Optically Active Defects Improve Carbon Nanotubes
Optically Active Defects Improve Carbon Nanotubes
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes - microscopically small tubular compounds that emit light in the near-infrared - chemists and materials scientists at Heidelberg University led by Jana Zaumseil have now demonstrated a new reaction pathway to enable such defect control.

The egg in the X-ray beam
A team of scientists has been using DESY's X-ray source PETRA III to analyze the structural changes that take place in an egg when you cook it. The work reveals how the proteins in the white of a chicken egg unfold and cross-link with each other to form a solid structure when heated. Their innovative method can be of interest to the food industry as well as to the broad field of research surrounding protein analysis.

Researchers first to link silicon atoms on surfaces
Researchers first to link silicon atoms on surfaces
Materials such as gallium arsenide are extremely important for the production of electronic devices. As supplies of it are limited, or they can present health and environmental hazards, specialists are looking for alternative materials. So-called conjugated polymers are candidates. These organic macromolecules have semi-conductor properties, i.e. they can conduct electricity under certain conditions.

Strong weld joints for aerospace applications
Strong weld joints for aerospace applications
Measurements at the Research Neutron Source help with the development of intelligent welding equipment When a rocket is launched, the weld seams on the enormous fuel tanks must withstand immense forces. To produce joints with the necessary strength, a process known as "friction stir welding" is used.

The very first structures in the Universe
Astrophysicists at the Universities of Göttingen and Auckland simulate microscopic clusters from the Big Bang The very first moments of the Universe can be reconstructed mathematically even though they cannot be observed directly. Physicists from the Universities of Göttingen and Auckland (New Zealand) have greatly improved the ability of complex computer simulations to describe this early epoch.

Breaking the warp barrier for faster-than-light travel
Breaking the warp barrier for faster-than-light travel
Astrophysicist at Göttingen University discovers new theoretical hyper-fast soliton solutions If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have -exotic- physical properties such as negative energy density.

Nanoscale sound waves vibrate artificial atom
Nanoscale sound waves vibrate artificial atom
A German-polish research team from Augsburg, Münster, Munich and WrocÅ‚aw successfully mixed nanoscale sound waves and light quanta. In their study published in Optica the scientists use an 'artificial atom' that converts the vibrations of the sound wave to single light quanta - photons - with unprecedented precision.

Pioneering molecule on its way into quantum computers
Researchers from the University of Jena and University of Florence, develop cobalt compound with special quantum properties In quantum computers, instead of electrical circuits being switched on or off, quantum mechanical states are altered. For this, suitable chemical compounds are needed. A research team from the University of Jena and the University of Florence has now succeeded in producing such a compound.

New insights into the mechanism of nuclear fission
New insights into the mechanism of nuclear fission
Nuclear physicists at the University of Cologne have contributed to an international research collaboration to show the way the spin of the two fragments, resulting from the splitting of an atomic nucleus, is generated / publication in Nature A series of experiments at the ALTO particle accelerator facility in Orsay, France, has revealed that the fragments resulting from nuclear fission obtain their intrinsic angular momentum (or spin) after fission, not before, as is widely assumed.

The size of the helium nucleus measured to femtometer accuracy
Helium is the second most abundant element in the universe after hydrogen. Helium nuclei consist of four components, namely two protons and two neutrons. Knowing the properties of the helium nucleus is crucial for fundamental physics, for example, in order to understand the processes in atomic nuclei that are heavier than helium.

Ingredients for earliest life forms preserved in 3.5 billion-year-old rocks
Researchers including Göttingen University discover biologically-relevant organic molecules in fluid inclusions It is generally accepted that the earliest life forms used small organic molecules as building materials and energy sources. However, the existence of such components in early habitats on Earth had not been proven to date.

A sharper look at the interior of semiconductors
A research team is developing a high-resolution imaging technique that can be used to investigate materials in a non-destructive manner and with nanometre precision Images provide information - what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward.

The transforming power of light
A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt University of Berlin have found out that semiconductors can be converted to metals and back more easily and more quickly than previously thought. This discovery may increase the processing speed and simplify the design of many common technological devices.

Captured lithium
Captured lithium
Neutrons show effective lithium and electrolyte distribution in lithium-ion cells In our smartphones, our computers and in our electric cars: We use rechargeable lithium-ion batteries everywhere. But their capacity drops after a while. Now a German-American research team has investigated the structure and functionality of these batteries using neutron diffraction: They discovered that the electrolyte fluid's decomposition products capture mobile lithium in the battery and that the distribution of lithium within the cell is surprisingly uneven.

Crystal structures in super slow motion
Physicists from Göttingen first to succeed in filming a phase transition with extremely high spatial and temporal resolution Laser beams can be used to change the properties of materials in an extremely precise way. This principle is already widely used in technologies such as rewritable DVDs. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation.
