High‐Power Performance of Textured Piezoelectric Ceramics Through Synergistic A‐Site Donor and B‐Site Acceptor Doping

open access: yesSmall Methods, EarlyView.
A/B‐site co‐doping combined with templated grain growth enables synergistic defect and domain engineering in textured PIN–PMN–PT ceramics. The approach simultaneously enhances piezoelectric response and mechanical quality factor, achieving a balanced soft–hard characteristic.

About the Dedekind psi function in Pauli graphs [PDF]

open access: yes, 2010
We study the commutation structure within the Pauli groups built on all decompositions of a given Hilbert space dimension $q$, containing a square, into its factors.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

open access: yessteel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

open access: yesStructural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

Tech Diplomacy and the Digital International Order: The Case of the EU–U.S. Trade and Technology Council

open access: yesGlobal Policy, EarlyView.
ABSTRACT This article examines the evolving role of the U.S.–EU Trade and Technology Council (TTC) in advancing the EU's digital diplomacy, with a particular focus on its contribution to global digital ordering. Positioned at the intersection of normative engagement and regulatory coordination, the TTC operates as a hybrid mechanism that integrates ...

Fatigue Performance and Failure Loads of Composition‐Gradient Multilayer Zirconia: Partial‐Coverage Restorations Versus Single Crowns at Different Thicknesses

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study investigated the influence of restoration type (partial‐coverage versus crown) and ceramic‐layer thickness on the fatigue behavior and failure load of monolithic composition‐gradient multilayer zirconia (4Y‐PSZ/5Y‐PSZ) molar restorations. Material and Methods Seventy‐two CAD/CAM‐fabricated monolithic zirconia restorations (

Impact of Zirconia Three‐Unit Resin‐Bonded Fixed Partial Dentures in the Posterior Region on Oral Health‐Related Quality of Life: A 12‐Month Longitudinal Observation

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Patient‐reported outcome measures (PROMs) remain limited in prosthodontics, including for ceramic resin‐bonded fixed partial dentures (RBFPDs), despite their growing relevance in minimally invasive practice. Oral health–related quality of life (OHRQoL) can be reliably assessed using the validated Oral Health Impact Profile −14 ...
