Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, Volume 97, Issue 6, Page 3267-3281, June 2026.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Promotion of 211 MAX Phase Formation through Bismuth A‐Site Solid Solution in Ti2(Al1‐xBix)C

Small Structures, Volume 7, Issue 6, June 2026.
Bi incorporation in the Ti–Al–C system stabilizes the 211 MAX phase across a wide synthesis window, suppressing competing 312 formation. The resulting Ti2(Al1‐xBix)C enables robust and scalable production of phase‐pure 211 precursors, while preserving the structural and functional characteristics of derived MXenes, demonstrating a practical route to ...

Dentifrices for preventing erosive tooth wear: An in vitro comparative study

European Journal of Oral Sciences, Volume 134, Issue 3, June 2026.
Abstract Erosive tooth wear is a progressive condition that compromises enamel structure and requires preventive strategies. This in vitro study aimed to compare the protective effects of fluoride‐based dentifrices containing various bioactive agents on sound enamel subjected to simulated erosive–abrasive challenges.

Microstructural Engineering of Sodium Potassium Niobate for Enhanced and Temperature‐Stable Electromechanical Response

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
This study investigates the synergistic effects of Ti‐doping and K5.4Cu1.3Ta10O29 (KCT) co‐modification on KNN ceramics to develop sustainable, lead‐free piezoelectrics. Co‐modification significantly enhances electromechanical coupling and the mechanical quality factor. The optimized KNN‐Ti‐KCT system achieves thermal stability comparable to commercial

Quantitative Determination of Iron Redox State in Copper–Iron–Silicate Slags by Electron Probe Microanalysis

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
The manuscript presents a quantitative approach for determining iron oxidation state in multicomponent silicate oxide systems through direct oxygen measurement by EPMA. The study provides experimentally validated data obtained under controlled equilibrium conditions. The methodology is intended to offer a broadly applicable framework for studying redox
