Abstract Achieving a near-zero temperature coefficient of resonant frequency (τf) while maintaining an ultra-high quality factor (Q×f) remains a critical challenge for microwave dielectric ceramics in next-generation 5G/6G communication systems. Herein, we report a configurationa...

Investigation of the Solidification Pathways and Magnetic Properties of Pr 6 Fe 13 M (M = Cu, Ga, Ge) Compounds

RE 6 Fe 13 M phases play an important role in enhancing coercivity of RE–Fe–B magnets, whereas their underlying mechanism remains unclear. Investigating the formation temperature, solidification path, and ground magnetic state of the Pr 6 Fe 13 M phase is essential for further cl...

Graphite-induced interface regulation in hard carbon for high-performance sodium-ion storage

In this work, we propose a graphite-induced interface strategy, in which pre-carbonized coconut shell carbon is wrapped with graphite paper and then carbonized. This process induces ordered rearrangement of carbon atoms on the hard carbon surface, forming ion transport channels c...

From bias to bots: discrimination and AI service preference

Purpose While artificial intelligence (AI)-enabled services have become increasingly prevalent, little is known about how discriminatory service encounters influence consumers’ preference for AI-based service providers. This research aims to investigate whether – and why – percei...

Equivalent End-Weakening Governing Crushing Modes and Crashworthiness of CFRP Tubes with Different End Triggers Under Quasi-Static Axial Compression

Quasi-static axial crushing tests were carried out on CFRP tubes with various end triggers (chamfer, tulip, crown, notch), aiming to reveal the joint regulation mechanism of geometric configuration and equivalent end-weakening on the crushing behavior of the tubes. Load–displacem...
