Cutting-edge technology allows for real-time monitoring of biomineralisation
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 ...
New form of spectroscopy provides insights for the development of resistance-free current transport at ambient temperature
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. ...
Researchers adapt 2D 'sandwich' for surface-enhanced Raman spectroscopy
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 ...
How the investigation of ion oscillations can lead to better batteries
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 ...
Research team produces new nanosheets for near infrared imaging
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 ...
How a molecule moves in the protective environment of a quantum fluid
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 ...
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 ...
New applications in the fields of quantum science, spectroscopy and chemistry
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 ...
Short pulses of strong laser light make the concentration of molecules visible
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 - ...
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 ...
