Fast Switching and High Polarization in Ferroelectric Hf0.5Zr0.5O2 Films
Small Science, EarlyView.Ferroelectric Hf0.5Zr0.5O2 thin films are grown under tuned redox conditions to simultaneously achieve high polarization and fast switching. Control of defect dipoles and internal fields enables stable domain wall motion without compromising performance. This work provides a pathway for designing fast and energy‐efficient ferroelectric devices.

Jet array impingement flow distributions and heat transfer characteristics. Effects of initial crossflow and nonuniform array geometry [PDF]
Two-dimensional arrays of circular air jets impinging on a heat transfer surface parallel to the jet orifice plate are considered. The jet flow, after impingement, is constrained to exit in a single direction along the channel formed by the jet orifice ...

Making Peace with Artificial Intelligence (AI) in Art Education
International Journal of Art &Design Education, EarlyView.Abstract Views regarding the access, position and use of Artificial Intelligence (AI) and AI pedagogies in transformative art education are changeable and controversial, particularly regarding influence, opportunity and ethics. This dialogic paper grapples with these concerns to ‘make peace’ with AI and its pedagogic development in art education.

A climate‐sensitive tropical urbanism under extreme heat†
Singapore Journal of Tropical Geography, EarlyView.Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.
