Researchers Show How 3-dimensional Nanostructures Can Be Printed Using Compact Desktop Devices
Lasers in conventional laser printers for paper printouts are very small. 3D laser printers for 3-dimensional microstructures and nanostructures, by contrast, have required big and expensive laser systems so far. Researchers of Karlsruhe Institute of Technology (KIT) and the Heidelberg University ...
Chemists succeed in producing synthesis and complete characterisation for the first time
Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent – geometrically speaking, a square. ...
Scientists achieve defect control with a new reaction pathway
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 ...
Phase transitions: Physicists observe the emergence of collective behaviour
Phase transitions describe dramatic changes in properties of a macroscopic system – like the transition from a liquid to a gas. Starting from individual ultracold atoms, Heidelberg University physicists were able to observe the emergence of such a transition with an increasing number of ...
New spectroscopic method
A new spectroscopic method now makes it possible to measure and visualise the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr Yana Vaynzof, a physicist at Heidelberg University. This novel visualisation technique enables ...
BASF and the University of Heidelberg extend cooperation
BASF and the University of Heidelberg will jointly continue operating their Catalysis Research Laboratory (CaRLa) for a further three years. The partners signed the appropriate contract to extend the research cooperation until 2022. At CaRLa, researchers work on issues relating to homogeneous ...
Many phenomena of the natural world evidence symmetries in their dynamic evolution which help researchers to better understand a system’s inner mechanism. In quantum physics, however, these symmetries are not always achieved. In laboratory experiments with ultracold lithium atoms, researchers ...
Researchers quantify rare CO2 variants using laser spectroscopy
For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils ...
Physicists reinvent the wheel with the help of a polymer fibre
Physicists and material scientists have succeeded in constructing a motor and an energy storage device from one single component. They used an elastic polymer fibre closed into a ring that was made to rotate on application of an external energy supply. The researchers from the universities in ...
Fermions in flatland pair up at very high temperatures: Physicists find evidence of an exotic state of matter
Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter where the constituent particles pair up when limited to two dimensions. The findings from the field of quantum physics may hold important clues to intriguing phenomena of ...
