Introduction: Air turbine dental drill noise contains high-frequency components that are of concern for patients and dental staff. Meanwhile, verbal communication between the dentist and patient is essential. Conventional active noise-cancelling headphones are ineffective for dental drill noise and si...

As AI becomes an increasingly prevalent tool across society, conversations have begun on whether it should be implemented into education. Teachers and parents are at the forefront of this dilemma, their opinions being an integral part of the ongoing discussion. This study explores ...

The world has been consistently experiencing a shortage of teachers. This issue is exacerbated as more developed nations advance technologically. The shortage of teachers disproportionately affects the quality of education in more developed countries, where educators are spread thin. However, tec...

Summary: The chatbot psychosis phenomenon is no longer just a hypothesis. We call for interdisciplinary frameworks to systematically investigate individual characteristics and artificial intelligence related factors which (on their own or in combination) cause or contribute to this phenomenon,&...

Al–Fe based alloys exhibit excellent high heat-resistance property but suffer from low strength and hardness because the soft aluminum matrix is interrupted by coarse needle/flake-like Al₃Fe phases. To refine Al₃Fe phases and strengthen Al matrix, we developed an in-situ liquid-solid reactio...

摘要：低合金化镁合金因其可加工性好、耐蚀性优异和成本低等优势，成为变形镁合金发展的重要趋势之一。焊接连接已成为推广应用这类材料的关键。然而，低合金化镁合金在焊接过程中存在焊缝晶粒粗大、有效强化相较少等组织软化问题，导致焊接强度不匹配等。本文基于镁合金焊接冶金学的相关理论，重点总结了调控低合金化镁合金焊缝组织的方法，并系统论述了焊缝组织演变过程和机理。最后，针对这类合金在焊接方面的应用需求，对该领域的发展趋势进行了展望。
