Tuning the microstructural and micro‐/nanomechanical properties of silicon nitride–carbon nanotube composites by powder oxidation

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Microstructure showing hexagonal α‐Si3N4 (green arrows) and CNTs distributed between beta‐Si3N4 (yellow arrows) and the oxidation impact to elastic moduli. Abstract The effects of the oxidation on the micro/nanohardness, density, and microstructure of the silicon nitride–carbon nanotube (Si3N4–CNT) composite were investigated.

Synthesis and thermal properties of dense Si─Al─C─N‐based polymer‐derived ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract In the present study, aluminum‐modified preceramic silicon polymers were synthesized via chemical modification of a commercially available organopolysilazane using an aluminum amido complex. The incorporation of aluminum into the polymer structure and its effect on ceramization behavior and processability as well as the thermal and mechanical ...

Load‐bearing performance comparison of lap joints in oxide ceramic matrix composites

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract This study evaluates the load‐bearing performance of oxide ceramic matrix composites (Ox‐CMCs) reinforced with continuous fibers, which contain fiber interruptions caused by the manufacturing process. Two different lap joint designs are evaluated: stepped and overlaying lap joints.

Color stability of precolored and extrinsically colored monolithic multilayered polychromatic zirconia: Effects of surface finishing and aging

Journal of Prosthodontics, Volume 35, Issue 2, Page 169-175, February 2026.
Abstract Purpose To explore the impact of zirconia types, coloring methods, and surface finishing on the color stability of monolithic multilayered polychromatic zirconia after artificial aging, including thermocycling and simulated toothbrushing. Materials and Methods Eighty square‐shaped zirconia samples were divided into 2 types (M3Y‐TZP and M6Y‐PSZ)
