Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.

Synthesis and Upconversion Luminescence of Nanoparticles Y2O3 and Gd2O3 Co-doped with Yb3+ and Er3+

, 2016
Upconversion nanoparticles (UCNs) find application in nanomedicine as biolabels to identify cancer cells. In this work, Y2O3: Er3+/ Yb3+ and Gd2O3: Er3+/ Yb3+ systems were fabricated by combustion synthesis (CS) and sol-gel (SG) methods to obtain ...

Effects of high‐speed sintering on the translucency and color of dental zirconia with different shades and yttria contents

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated the effects of high‐speed sintering on the translucency and color of various yttria‐stabilized zirconia (YSZ) compositions and identified factors influencing these properties to improve clinical predictability. Materials and Methods A total of 144 disc‐shaped specimens fabricated from 3YSZ, 4YSZ, and 5YSZ pucks in ...

Towards Season‐Specific Feeds: Maximising Protein Digestibility and Reducing Waste in Hybrid Abalone (Haliotis rubra × Haliotis laevigata) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 5, October 2026.
ABSTRACT Australian abalone grow‐out aquaculture relies on formulated feeds to provide for the nutritional requirements of the animal. At the same time, grow‐out systems are subject to seasonal water temperature fluctuations. As such, the economic and environmental performance of cultured abalone is inherently tied to the utilisation efficiency of ...
