Assessing the microstructure of simple rhamphothecae in chickens (Aves: Galliformes: Gallus gallus domesticus)

Journal of Anatomy, EarlyView.
Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, Volume 15, Issue 26, 10 July 2026.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Predicting the creep compliances of short fiber reinforced polymer composites from the matrix creep using an elementary volume model Vorhersage der Kriechkomplianzen polymerer Kurzfaserverbunde auf Basis des Matrixkriechens mit Hilfe eines Elementar‐Volumen‐Modells

Materialwissenschaft und Werkstofftechnik, Volume 57, Issue 6, Page 567-585, June 2026.
Creep prediction of short fiber composites: A prediction tool is presented based on an elementary volume model. It predicts creep compliances of injection molded short fiber reinforced composites using only the matrix creep. The assumption “perfect fiber matrix adhesion” underestimates the creep enabling the introduction of an adhesion factor.
