Hidden order in windswept sand

An interdisciplinary team including researchers from Leipzig University has analyzed an extensive collection of sand samples from so-called megaripple fields around the world and gained new insights into the composition of ...

Quantum effects detected in hydrogen and noble gas collisions

A Freie Universität Berlin research team headed by quantum physicist Professor Christiane Koch has demonstrated how hydrogen molecules behave when they collide with noble gas atoms such as helium or neon. In an article published ...

Graphene nanoribbons get metallic

Researchers at Aalto University have succeeded in experimentally realizing metallic graphene nanoribbons (GNRs) that are only 5 carbon atoms wide. In their article published in Nature Communications, the research team demonstrated ...

Thawing permafrost releases greenhouse gas from depth

Which effects did the heat wave of summer 2020 have in Siberia? In a study led by the University of Bonn (Germany), geologists compared the spatial and temporal distribution of methane concentrations in the air of northern ...

Chemists synthesize 'flat' silicon compounds

Chemists at the University of Bonn (Germany) have synthesized extremely unusual compounds. Their central building block is a silicon atom. Different from usual, however, is the arrangement of the four bonding partners of ...

Molecular rings mystery solved after 20 years

Although the double benzene molecule tried to reveal its structure in experiments in 1993, chemists at the time were unable to find an explanation for the spectral peaks they saw. Now, 20 years later, Nijmegen theoretical ...

High efficient solar water heating achieved with nanoparticles

A research team in Japan discovered through numerical calculations that nanoparticles of transition metal nitrides and carbides absorb sunlight very efficiently, and confirmed experimentally that nitride nanoparticles, when ...
