Homogeneous crystallization via sustained solvent-extraction channels for methylammonium-free all-perovskite tandem solar cells
Replacing volatile methylammonium (MA^(+)) with formamidinium (FA^(+)) or cesium (Cs^(+)) cations in mixed Pb-Sn perovskite compositions improves thermal resilience. Nevertheless, the low-solubility Cs-based perovskite tends to preferentially crystallize into a dense Cs-rich surface layer during the AS-assisted crystallization process, which impedes the AS to extract the internal solvent. Here, we introduce a multi-Lewis-base modulator to maintain sustained solvent-extraction channels (SSC) open...

Psycho-socio-economic factors and risk of cardiorenal multimorbidity in middle to older-aged adults: prospective findings from the Canadian longitudinal study on aging
Psycho-socio-economic factors (PSEFs) such as income and homeownership may influence the prevalence of cardiorenal multimorbidity (CRM), yet their prospective associations with CRM risk remain unclear. This study aimed to estimate CRM incidence and examine its relationships with multiple PSEFs in a nationally representative Canadian cohort. We analyzed data from 16,557 participants (mean age: 60.4 years; 48.9% men) in the Canadian Longitudinal Study on Aging (CLSA) who were free of CRM at...
