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 ...

Morphology and mechanical properties of poly(methylmethacrylate)-b-poly(alkylacrylate)-b-poly(methylmethacrylate) [PDF]

Polymer, 2001
Abstract A series of well-defined poly(methylmethacrylate) (PMMA)-b-poly(alkylacrylate)-b-PMMA triblock copolymers (MAM) has been synthesized by transalcoholysis of PMMA-b-poly(tert-butylacrylate)-b-PMMA precursors by alkyl alcohols. The molecular weight (MW) of the outer PMMA blocks is in the 10,000–50,000 range, compared to 50,000–200,000 for the ...

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

Advanced Science, Volume 13, Issue 21, 13 April 2026.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of polymer mechanochemistry, polymer physical properties, and material transfer, where ion‐derived dipoles modulate the interfacial potential and mechanochemically generated electronic states and work function differences drive electron transfer, providing a unified ...

Organophosphide: Eine neue Klasse der Luminophorliganden für Kupfer(I)‐Carben‐basierte TADF‐Emitter und Photokatalysatoren

Angewandte Chemie, Volume 138, Issue 13, 23 March 2026.
Der Einsatz von Dimesitylphosphid als höheres Homolog der etablierten Amidoliganden für Charge‐Transfer‐Kupfer(I)‐Komplexe führt zu einer Rotverschiebung der Emission um 3645 cm–1 in den rot‐orangen Spektralbereich im Festkörper sowie in den NIR‐Bereich in Lösung. Die thermisch‐aktivierte verzögerte Fluoreszenz weist hohe Dissymmetriefaktoren von glum =
