Floating Platform Geometry as a Frequency‐Selective Mechanism for Triboelectric Wave Energy Harvesting

SmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Ocean wave energy has enormous potential for sustainable power generation but conventional technologies often face challenges in efficiency, durability, and adaptability to specific sites. Triboelectric nanogenerators (TENGs) are able to convert irregular and low frequency water motion into electrical energy, but their performance depends on ...

Well‐being decline during adolescence: school transition as a predominant driver beyond age progression

Journal of Child Psychology and Psychiatry, Volume 67, Issue 9, Page 1513-1524, September 2026.
Background The transition from primary‐to‐secondary school significantly impacts students' well‐being. However, existing research provides limited insight into the long‐term impact of school transition on well‐being, and no studies have disentangled age‐related changes from transition‐specific effects.
