New Scientific Finding: Light Can Be Used to Control Molecular Handedness

This new process could be particularly useful in chemically synthesizing compounds

15-Dec-2022

In a recent study, researchers at Freie Universität Berlin, the DESY research center in Hamburg, Kiel University, and Kansas State University have shown how light can turn a planar molecule into a chiral molecule with just one particular handedness, providing a solution to the long-standing ...

New insight into how long-banned chemicals unleash their toxicity inside the body

28-Nov-2022

Polychlorinated biphenyls (PCBs) were widely used in industrial and commercial products including plastics, paints, electronic equipment and insulating fluids. Their manufacture was extensively banned from the late 70s onwards due to their toxicity, however large amounts still remain in our ...

Using chirality for faster, smaller, and more efficient data storage devices

Researchers present an innovative approach for enhancing electronic devices

28-Oct-2022

Researchers at Johannes Gutenberg University Mainz (JGU) are pursuing a completely new and unconventional strategy to improve the way data can be processed and – in particular – stored. Together with their partners at the Hebrew University of Jerusalem, they have been granted funding by the Carl ...

Changing direction: Research team discovers switchable electronic chirality in an achiral Kagome superconductor

14-Oct-2022

An international research team led by the Department of Microstructured Quantum Matter at the MPSD reports the first observation of switchable chiral transport in a structurally achiral crystal, the Kagome superconductor CsV₃Sb₅. Its work has been published in Nature. Whether or not an object is ...

Chiral sources for metamaterial interface waveguides

A broadband near-field chiral source in the microwave band enables comparison of different edge states to advance applications in integrated photonics and wireless devices

25-Jul-2022

Metamaterial interface waveguides can confine and guide electromagnetic (EM) waves, which has attractive potential in integrated photonics physics and wireless devices, from radio frequencies to optical bands. The energy flow in waveguides can be fully controlled by sorting the near-field light ...

Making it easier to differentiate mirror-image molecules

Researchers have shown that mirror-image substances – so-called enantiomers – can be better distinguished using helical X-ray light

06-Jul-2022

Using a new method, scientists are better able to distinguish between mirror-image substances. This is important amongst others in drug development, because the two variants can cause completely different effects in the human body. Researchers from Paul Scherrer Institute PSI, EPF Lausanne ...

Scientists create luminescent gels with multitude of applications from counterfeiting to bio-sensing

15-Jun-2022

Scientists from Trinity College Dublin have taken inspiration from nature to create luminescent, self-healing gels with a suite of potential applications ranging from bank note counterfeiting to next-gen bio-sensing and imaging. Crucially, the scientists have been able to introduce guanosine (a ...

Tracking chirality in real time

“These ground-breaking experiments show that time-resolved circular dichroism is uniquely suited to capture the molecular motion that drives many (bio)chemical processes”

01-Jun-2022

Scientists at EPFL have developed a new laser-based technique that can measure ultrafast changes in the structural symmetry of molecules, called chirality, tracking their conformational shifts in real time. In a collaboration with researchers from the Universities of Geneva and Pisa, the ...

Using X-rays to identify liquid chiral molecules

New method can for the first time distinguish their components in liquid form – and more effectively than ever before

25-May-2022

Sugars, amino acids, drugs - chiral molecules are everywhere. Researchers in the AQUACHIRAL project at the Fritz-Haber-Institut have used X-rays to study hair-thin liquid jets of these molecules. Using a new method, they can now for the first time distinguish their components in liquid form – and ...

Controlling mirror images

Scientists has found a way to address chiral molecules separately

06-May-2022

Using a new experimental method, a team led by physicist Sandra Eibenberger-Arias of the Fritz-Haber-Institut has transferred the mirror-image forms of chiral molecules into different rotational states more efficiently than ever before. This opens doors to a deeper understanding and ...
