Synthesis and Optical Properties of Ln2Ln′2‐Tetranuclear Lanthanide(III) Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of new heterotetranuclear lanthanide complexes (Ln2Ln′2) is synthesized to study Ln‐to‐Ln′ energy transfer. Using stable dinuclear precursors, Tb2Yb2 and Nd2Tb2 are prepared and show visible/NIR emission. Reduced Tb3+ lifetimes suggest energy transfer to Yb3+ or Nd3+, offering a modular route to mixed‐lanthanide systems.

Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...

Challenges to parental engagement in K‐12 online learning during the pandemic: Lessons learned and a tripartite model for future involvement

open access: yesFuture in Educational Research, EarlyView.
Abstract Online learning became a central feature of education during the COVID‐19 pandemic, as traditional classrooms were rapidly replaced by virtual environments within students' homes through platforms such as Zoom. This abrupt transition required parents of K‐12 students to assume the unfamiliar role of at‐home educators, often without adequate ...

Ce‐LLMs: Status and trends of education‐specific large language models developed in China

open access: yesFuture in Educational Research, EarlyView.
Abstract The prevalence of AI hallucination in general‐purpose large language models (LLMs) poses significant pedagogical challenges, particularly in terms of content credibility and reliability. In response, China has launched the development of education‐specific LLMs as a national strategic initiative. However, current reports on Chinese educational
