Effects of postural intervention using a risshin chair on physical posture, class time perception, and subjective well‐being in junior high school students

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1341-1361, September 2026.
Abstract Background Research based on embodied cognition has demonstrated that physical posture, particularly an upright seated posture, can influence emotions and cognition. However, although students spend most of the day sitting in classrooms, intervention research on upright seated postures suitable for learning environments is limited.

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

Polymer International, Volume 75, Issue 8, Page 722-728, August 2026.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Depth‐Resolved Photo‐Degradation of Perovskite Layer in Solar Cells Stressed Under ISOS Light‐Aging Protocol Conditions: The Role of Substrate, Electron‐Transport‐Layer and Perovskite Deposition Method

Solar RRL, Volume 10, Issue 13, 15 July 2026.
Herein, a depth‐resolved analysis of ambient‐air‐processed perovskite layers employed in carbon‐based hole‐transport‐layer‐free photovoltaics subjected to ISOS light‐aging is provided. In all cases, the light‐induced degradation is demonstrated to start near both top and buried interfaces, and spread into the bulk, affecting perovskite crystals quality,
