‘Where are the adults?’: Troubling child‐activism and children's political participation
British Educational Research Journal, EarlyView.Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

In-Situ Fretting Wear Analysis of Electrical Connectors for Real System Applications
Journal of Manufacturing and Materials Processing, 2019 The tribological behavior of electrical contacts, especially separable type electrical connectors at low contact loads, are considered. The reliability of these connectors has been a major concern due to the fretting phenomenon that can lead to an ...

Engineered Metal–Organic Frameworks‐Based Materials for Environmental Detection
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Engineered metal–organic frameworks (MOFs) regulated by various material modification strategies are discussed for environmental contaminant detection under different sensing mechanisms, providing future improvements of MOFs in environmental detection. Sensitive and selective detection of contaminants is crucial for environmental protection.
