Sharper than ever: Physicists make molecular vibrations more detectable

The new method will improve the understanding of interactions in molecular systems and to further develop simulation methods

22-Sep-2022 - In molecules, the atoms vibrate with characteristic patterns and frequencies. Vibrations are therefore an important tool for studying molecules and molecular processes such as chemical reactions. Although scanning tunnelling microscopes can be used to image individual molecules, their vibrations ...

NanoCar Race II: Eight teams from three continents gather for the world's smallest race - the race of the molecules

24-Mar-2022 - When they hear the term "24-hour race," many people might think of Le Mans, Daytona, or even the Nürburgring. Images of colorful cars racing by at breakneck speed, accompanied by deafening noise and the smell of burning high-performance fuels may appear in the mind's eye. But at the NanoCar Race ...

A unique scanning tunnelling microscope with magnetic cooling to study quantum effects developed

"Adiabatic cooling is a real quantum leap for scanning tunneling microscopy"

02-Sep-2021 - Scanning tunnelling microscopes capture images of materials with atomic precision and can be used to manipulate individual molecules or atoms. Researchers have been using the instruments for many years to explore the world of nanoscopic phenomena. A new approach by physicists at Forschungszentrum ...

Autonomous Robot Plays with NanoLEGO

Scientists are developing an autonomous artificial intelligence system that can selectively grip and move individual molecules

07-Sep-2020 - Molecules are the building blocks of everyday life. Many materials are composed of them, a little like a LEGO model consists of a multitude of different bricks. But while individual LEGO bricks can be simply shifted or removed, this is not so easy in the nanoworld. Atoms and molecules behave in a ...

An ultrafast microscope for the quantum world

28-Jan-2020 - Processes taking place inside tiny electronic components or in molecules can now be filmed at a resolution of a few hundred attoseconds and down to the individual atom. The operation of components for future computers can now be filmed in HD quality, so to speak. Manish Garg and Klaus Kern, ...

Sensing magnetism in atomic resolution with just a scanning tunneling microscope

Researchers use single molecule on microscope tip as a sensor to detect magnetic moments with unprecedented spatial resolution

07-Nov-2019 - Scientists from the University of Strasbourg, France, in close collaboration with colleagues from the research centers in San Sebastián, Spain, and Jülich, Germany, have achieved a breakthrough in detecting the magnetic moments of nanoscale structures. They succeeded in making the magnetic ...

Single molecule control for a millionth of a billionth of a second

11-Sep-2018 - Physicists at the University of Bath have discovered how to manipulate and control individual molecules for a millionth of a billionth of a second, after being intrigued by some seemingly odd results. Their new technique is the most sensitive way of controlling a chemical reaction on some of the ...

Controlling Quantum States Atom by Atom

13-Jun-2016 - An international consortium led by researchers at the University of Basel has developed a method to precisely alter the quantum mechanical states of electrons within an array of quantum boxes. The method can be used to investigate the interactions between various types of atoms and electrons, ...

Handshake of atoms: lefties or righties?

25-Feb-2016 - A team of researchers from the Department of Physics at Hamburg University, together with col-leagues from the Radboud university in Nijmegen, the FZ Jülich and the MPI of Solid State Research in Stuttgart, explored the atomistic origin of magnetization handedness in a structure containing as few ...
