Covalent Organic Frameworks in Smart Food Packaging: Advances, Challenges, and Future Prospects

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT Food preservation challenges have positioned packaging as a rapidly evolving, innovation‐driven field, with smart packaging offering transformative solutions. Among advanced materials, covalent organic frameworks (COFs) have attracted growing attention due to their permanent porosity, structural tunability, high surface area, and chemical ...

Mechanical Property and Microstructure of TZP and TZP/Al₂O₃ Composites

, 1986
There are various types of microstructure in the TZP materials and their composite materials. The fine-grained microstructure is well-known as the basic microstructural type of TZP materials. Y-TZP and Ce-TZP belong to this group.

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

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 11, Page 2177-2191, November 2026.
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 Glazing Dwell Time and Cooling Duration on Flexural Strength and Surface Microhardness of 3 mol% Yttria‐Stabilized Tetragonal Zirconia: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, Volume 38, Issue 11, Page 2199-2206, November 2026.
ABSTRACT Objective To evaluate the effect of glazing dwell time and cooling duration on the flexural strength and surface microhardness of high‐translucency 3 mol% yttria‐stabilized tetragonal zirconia polycrystal (3Y‐TZP). Materials and Methods Total of 108 rectangular zirconia specimens (20 × 4 × 2 mm) were fabricated from preshaded monolithic blocks

6 mol% calcia stabilized TZP – a perfect substitute for 3 mol% yttria stabilized TZP?

Open Ceramics
Calcia stabilized tetragonal zirconia polycrystals (Ca-TZP) represent a promising alternative to Y-TZP for medical and engineering applications, as they avoid the use of critical raw materials.
