Investigation of Crystal Structure Change and Mechanical Properties of 3D Printed PLA After Annealing

open access: yesPolymer Engineering &Science, EarlyView.
Thermal annealing of FDM‐printed PLA significantly enhances longitudinal tensile and flexural strengths by increasing crystallinity to 46.6%. However, transverse properties remain constrained by weak interlayer adhesion, providing crucial insights into the anisotropic thermo‐mechanical behavior of printed biopolymers for demanding engineering ...

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.

Neue Einblicke in ein Schlüsselmaterial für Planetenphysik, Fusion und Materialforschung: Flüssiger Kohlenstoff

open access: yesPhysik in unserer Zeit, EarlyView.
Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...

Harnessing Natural Compounds in Psoriasis: Targeting Cellular Pathways for Effective Therapy

open access: yesPhytotherapy Research, EarlyView.
Natural compounds act on key cellular pathways in psoriasis by suppressing keratinocyte hyperproliferation, modulating Th17/IL‐17‐mediated immune responses, and reducing oxidative stress. These multi‐target effects highlight their potential as safer adjunctive therapies alongside conventional treatments.
