The indestructible light beam

Researchers create special light waves that can penetrate even opaque materials as if the material was not even there

14-Apr-2021

Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way. However, as a research team from TU Wien (Vienna) and Utrecht University (Netherlands) has now been able to show, there is a class of very special light ...

Electromagnetic Fields of Nanostructures Visualized in 3D for the First Time

30-Mar-2021

Researchers at Graz University of Technology (TU Graz) and the University of Graz, together with experts from France, have succeeded in imaging so-called surface phonons in three dimensions for the first time. The research success could accelerate the development of new, efficient ...

New microscopy method resolves fluorescent molecules with resolution at the nanometer scale

22-Mar-2021

Scientists working with Stefan Hell at the Max Planck Institute (MPI) for Biophysical Chemistry in Göttingen and the Heidelberg-based MPI for Medical Research have developed another light microscopy method, called MINSTED, which resolves fluorescently labeled details with molecular sharpness. ...

It's snowing plastic

New technique detects minute particles of plastics in snow, rain and even soil

22-Mar-2021

The snow may be melting, but it is leaving pollution behind in the form of micro- and nano-plastics according to a McGill study that was recently published in Environmental Pollution. The pollution is largely due to the relatively soluble plastics found in antifreeze products (polyethylene ...

Solar cells: Losses made visible on the nanoscale

19-Mar-2021

Solar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. Now, for the first time, a team at Helmholtz-Zentrum Berlin (HZB) and ...

Determining the structure of a molecule with laser-induced electron diffraction

11-Mar-2021

Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we need at least 1000 times better resolution. Laser induced electron diffraction (LIED) is a technique ...

Scientists probe electronic angular momentum to a chemical reaction for the first time

01-Mar-2021

A chemical reaction can be understood in detail at the quantum state-resolved level, through a combined study of molecular crossed beam experiments and theoretical quantum molecular reaction dynamics simulations. At a single collision condition, the molecular crossed beam apparatus is able to ...

On the line: Watching nanoparticles get in shape

New method could advance next-generation applications in medicine, cosmetics, and petroleum recovery

26-Feb-2021

Liquid structures - liquid droplets that maintain a specific shape - are useful for a variety of applications, from food processing to cosmetics, medicine, and even petroleum extraction, but researchers have yet to tap into these exciting new materials' full potential because not much is known ...

Ultrafast Electron Dynamics in Space and Time

"We believe that our findings represent a crucial breakthrough towards the goal of tracing electrons through chemical reactions in space and time"

22-Feb-2021

In textbooks and explanatory videos, they are often depicted as colourful balloons or clouds: electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only ...
