Quasi-2D perovskites have been pivotal in recent efforts to stabilize perovskite solar cells. Despite the stability boost provided when these materials are introduced in perovskite solar cells, little is known about the intrinsic light and environmental stability of quasi-2D perovskites. In this study, we characterize the photostability of exfoliated quasi-2D perovskite single crystals in air using photoluminescence, infrared, X-ray fluorescence, and energy-dispersive X-ray spectroscopy.

Material And Methods: 390 Adults with physical disabilities and/or chronic diseases participated in the Rehabilitation, Sports and Active lifestyle (ReSpAct) 2.0 study with measurements at 3-6 weeks before discharge (T0), and 14 (T1), 33 (T2), and 52 weeks (T3), and 6-8 years (T4) after discharge from rehabilitation.
Context: To improve physical activity (PA) participation in people with spinal cord injury (SCI), an international panel co-created theory- and evidence-based best practices for SCI PA counseling. This study aimed to identify and compare Canadian and Dutch counselors' knowledge, skills, and confidence in using these best practices.
Methods: An online survey was conducted in Canada and the Netherlands.
