Article Synopsis
- - The study explores using vacuum distillation (VD) to effectively purify aluminum (Al) from Al-Mg alloys, employing advanced models to determine activity coefficients for the alloy components.
- - The research identifies the non-random two-liquid (NRTL) model as the most accurate for computing these coefficients and creates a vapor-liquid equilibrium (VLE) diagram to inform purification limits within specific temperature ranges.
- - Experimental results demonstrate that the VD method can achieve a high Al purity of 99.9989% while maintaining a direct recovery efficiency of 97.98%, all while adhering to eco-friendly standards in metallurgical practices.
Lithium metal anodes generally suffer from uncontrolled dendrite growth and large volume change, while traditional skeletons such as LiIn and LiSn are too heavy and discontinuous to offer highly efficient structural supportability for composite Li anodes. In this work, lightweight and stable fiber-clustered skeletons, which are composed of LiB fibers and jointed LiSi nanoparticles, can be obtained by smelting SiB powder and Li ingots. In addition to serving as both ionic and electronic conductors for composite Li anodes, the stable skeletons reduced volumetric fluctuation by offering uniform, heterogeneous, and continuous architectures while suppressing lithium dendrites with low nucleation overpotential and diffusion energy barrier.

- Autism Spectrum Disorder (ASD) affects gray matter, but the impact on structural-functional coupling in white matter (WM) is less understood; this study investigates that using brain imaging techniques.
- The research analyzed data from 89 ASD and 63 typically developing individuals, examining the relationship between WM coupling and ASD severity, utilizing machine learning for prediction accuracy.
- Findings showed ASD individuals had reduced WM structural-functional coupling, particularly in critical brain areas, and integrating multi-model analysis outperformed single-model approaches in predicting severity of ASD symptoms.
