Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

This comprehensive review systematically evaluates high‐entropy alloys as a transformative platform for sustainable electrocatalysis. By structurally mapping the interplay between elemental selection boundaries, multi‐dimensional morphological engineering, innovative synthesis driving forces and mechanistic understanding through in situ ...

We present a multidecadal analysis of the seismic response of a midrise reinforced concrete (RC) building in Taipei, Taiwan, combining legacy strong‐motion accelerograph (SMA‐1) data with recent recordings from a dense array of low‐cost microelectromechanical systems (MEMS)‐based Quake Structural Integrity System (QSIS) sensors.

ABSTRACT The exceptional ductility of face‐centered cubic high/medium‐entropy alloys (H/MEAs) is counterbalanced by intrinsically restrained yield strength, fundamentally compromising their application in structural and functional materials. Here, a novel carbon (C)‐driven precipitation strategy is introduced to promote discontinuous precipitation (DP)

ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Enhanced Microwave Attenuation via Coupled Ni3ZnC0.7/Ni3InC0.5 Heterogeneous Interfaces
ABSTRACT The growing complexity of electromagnetic environments places increasingly stringent demands on microwave absorbers, particularly regarding broadband attenuation, impedance matching in ultrathin configurations, and structural stability. Herein, we propose a dual nonstoichiometric carbide synergistic regulation strategy, in which Ni3ZnC0.7 and ...

ABSTRACT Capacitive deionization (CDI) using activated carbon (AC) electrodes holds great promise for seawater desalination, yet its practical application is severely constrained by the intrinsic hydrophobicity of carbon surfaces. Herein, we propose a solid‐state superhydrophilic modulation strategy that physically wet‐mixes superhydrophilic MOF ...

ABSTRACT Powder metallurgy (PM) near‐α Ti alloys are often constrained by a pronounced strength–ductility trade‐off, due to the coarse lamellar microstructure formed during the sintering process. To address this issue, a thermomechanical route combining cyclic hot rolling with short‐time solution treatment was developed to improve the mechanical ...

ABSTRACT Achieving excellent strength–ductility synergy remains a critical scientific challenge for ordered Ni3Al‐based intermetallic alloys. In this work, a hierarchical heterostructure was deliberately architected in a novel L12‐type Ni3Al‐based high‐entropy aluminide, (Ni38.5Co38.5Al11.5Ti5Cr4.5Ta2)99.7B0.1C0.2 (at%), through a simple and cost ...

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM
Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.
