Surface wear and roughness of experimental composites containing calcium orthophosphate particles following toothbrush abrasion

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract This study evaluated experimental composites containing dicalcium phosphate dihydrate (DCPD) particles for toothbrush wear and roughness. Composites containing bisphenol‐A glycidyl dimethacrylate/triethylene glycol dimethacrylate with 50 vol% inorganic fraction consisting of barium glass and DCPD (35:15 and 15:35 vol%) or barium glass only ...

Effect of Sintering Parameters on the Densification, Microstructure, and Mechanical Performance of ZrB2–SiC Ceramics

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
This graphical abstract illustrates the systematic investigation of Spark Plasma Sintering (SPS) parameters, temperature, pressure, and dwell time, on the densification and mechanical performance of ZrB2–20 vol% SiC composites. It highlights the critical influence of powder processing history (WC vs.

Wire Arc Directed Energy Deposition of Aluminum–B4C Composites

open access: yesInternational Journal of Applied Ceramic Technology, Volume 23, Issue 2, April 2026.
ABSTRACT The scalable fabrication of structural‐grade aluminum metal matrix composites (A‐MMCs) remains constrained by inherent limitations of conventional processing routes and laser‐based additive manufacturing (AM) methods. In this work, we demonstrate the development of a hybrid wire arc directed energy deposition (WA‐DED) platform for the near‐net‐

Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.
ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

Microstructural and Thermal Evolution of Turbostratic and Crystalline hBN Using SPS With In‐Situ YAG

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
hBN ceramics with an in‐situ formed YAG phase were fabricated by SPS using turbostratic and crystalline powders. The results show that the microstructure, textural orientation, and functional properties of hBN ceramics can be significantly controlled by sintering temperature, starting powder structure, and additives.

The Effect of Preheating, Resin‐Based Composite, and Wire Types of Orthodontic Lingual Fixed Retainers on the Load at Failure: A Comparative In‐Vitro Study

open access: yesJournal of Esthetic and Restorative Dentistry, Volume 38, Issue 4, Page 892-904, April 2026.
ABSTRACT Background Preheating resin‐based composites (RBC) has been shown to enhance their mechanical and bonding properties. Nevertheless, the effect of preheating RBCs on the performance of orthodontic lingual fixed retainers has been scarcely reported.
