Thickness effect on optical behavior of monolithic zirconia [PDF]
BioinformationAchieving optimal esthetics in all-ceramic restorations remains a challenge due to variations in translucency and color influenced by material thickness. Therefore, this study aimed to evaluate the effect of thickness on the optical properties of monolithic zirconia compared to veneered zirconia.

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels
steel research international, EarlyView.This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.
