Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Effects of Acidic Media on the Mechanical and Optical Properties of Digitally Designed Restorative Materials

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This investigation assessed how acidic environments affect the optical behavior, surface roughness, and hardness of a newly developed 3D‐printed permanent resin compared with commonly used computer‐aided design/computer‐aided manufacturing restorative blocks.

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 ...

Surface roughness, stainability, and translucency of an additively manufactured interim resin reinforced with a commercially available ceramic composite concentrate after coffee thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To compare the surface roughness (Ra), stainability, and translucency of a ceramic composite concentrate‐reinforced interim resin with its corresponding non‐reinforced formulation and with a ceramic‐filled resin indicated for definitive use after coffee thermal cycling.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics
