Nature Unveiling Herself Before Science

Cutting-edge technology allows for real-time monitoring of biomineralisation

22-May-2020

21st century societal challenges such as demographic developments and an ageing population demand for new functional materials, such as for bone prostheses. Nature often serves as inspiration when designing these materials. In a recent study published in Analytical Chemistry, a team led by ERC ...

The Higgs boson and superconductivity

New form of spectroscopy provides insights for the development of resistance-free current transport at ambient temperature

20-May-2020

Without the Higgs mechanism, particles would have no mass. The Higgs boson, which was discovered in 2012, is therefore also referred to as the “God particle”. It arises as an oscillating excitation of the Higgs field, which penetrates the world. Superconductivity displays similar properties. ...

2D sandwich sees molecules with clarity

Researchers adapt 2D 'sandwich' for surface-enhanced Raman spectroscopy

18-May-2020

A sandwich of molybdenum, sulfur and selenium turns out to be deliciously useful for detecting biomolecules. Tests at Rice University's Brown School of Engineering of a two-dimensional Janus compound showed it could be an effective and universal platform for improving the detection of ...

When ions rattle their cage

How the investigation of ion oscillations can lead to better batteries

07-Apr-2020

Electrolytes play a key role in many areas: They are crucial for the storage of energy in our body as well as in batteries. In order to release energy, ions - charged atoms - must move in a liquid such as water. Until now the precise mechanism by which they move through the atoms and molecules of ...

A pigment from ancient Egypt to modern microscopy

Research team produces new nanosheets for near infrared imaging

25-Mar-2020

Egyptian blue is one of the oldest manmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen ...

Researchers observe ultrafast processes of single molecules in liquid helium for the first time

How a molecule moves in the protective environment of a quantum fluid

24-Mar-2020

Markus Koch, head of the research group Femtosecond Dynamics at the Institute of Experimental Physics at TU Graz, and his team develop new methods for time-resolved femtosecond laser spectroscopy to investigate ultrafast processes in molecular systems. In 2018 the group demonstrated for the first ...

Unraveling the optical parameters: New method to optimize plasmon enhanced spectroscopy

23-Mar-2020

For exploring the nanoscale far beyond the optical resolution limit, tip-enhanced Raman spectroscopy (TERS) is widely recognized as an essential yet still emergent technique. Using this marker-free spectroscopic method scientists gain insights into the structural and chemical composition of ...

Perturbation-free studies of single molecules

New applications in the fields of quantum science, spectroscopy and chemistry

16-Mar-2020

Researchers of the University of Basel have developed a new method with which individual isolated molecules can be studied precisely – without destroying the molecule or even influencing its quantum state. This highly sensitive technique for probing molecules is widely applicable and paves the ...

Sensitive detection of molecules

Short pulses of strong laser light make the concentration of molecules visible

13-Mar-2020

To observe molecules, one has to use sensitive tools. Such measurements would be important for determining the concentration of minute particles in blood samples or during neuronal information transfer in the brain. A team of Max Planck scientists has taken a decisive step in this direction - ...

'Tickling' an atom to investigate the behavior of materials

09-Mar-2020

Scientists and engineers working at the frontier of nanotechnology face huge challenges. When the position of a single atom in a material may change the fundamental properties of that material, scientists need something in their toolbox to measure how that atom will behave. A research team led by ...
