Bionisch inspirierte Strahlungskühlung: Kühlen wie die Silberameise

open access: yesPhysik in unserer Zeit, EarlyView.
Wie kann ein wenige Millimeter großes Insekt helfen, Gebäude ohne Strom zu kühlen? Die Silberameise überlebt extreme Hitze mithilfe raffinierter Mikrostrukturen, die einen Großteil des Sonnenlichts zurückwerfen und gleichzeitig thermische Energie über Infrarotstrahlung in den Weltraum abführen.

Multifunktionale DNA‐Moiré‐Supergitter: Moiré‐Strukturen aus den Bausteinen des Lebens

open access: yesPhysik in unserer Zeit, EarlyView.
Moiré‐Strukturen sind längst ein Schlüsselbegriff in der modernen Festkörperphysik. Sie entstehen, wenn sich zwei periodische Materialgitter mit leicht unterschiedlichen Gitterkonstanten oder Orientierungen übereinanderlagern. Das so entstehende großflächige Interferenzmuster, das als Moiré‐Muster bezeichnet wird, kann die physikalischen Eigenschaften ...

Evaluating the realism of double moment parameterised particle size distributions in a midlatitude frontal ice cloud with complex microphysics

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Uncertainties in the representation of ice particle size distributions (PSDs) cause inaccuracies in parameterisations of clouds. In this study, observed PSDs from a midlatitude frontal case study are compared with gamma PSDs with the same concentration and ice water content.
