Controllable Iodoplumbate-Coordination of Hybrid Lead Iodide Perovskites via Additive Engineering for High-Performance Solar Cells.

The crystallization and growth of perovskite crystals are two crucial factors influencing the performance of perovskite solar cells (PSCs). Moreover, iodoplumbate complexes such as PbI, PbI, and PbI in perovskite precursor solution dictate both the quality of perovskite crystals and the optoelectrical performance of PSCs. Here, we propose an iodoplumbate-coordination strategy that employs pentafluorophenylsulfonyl chloride (PTFC) as an additive to tailor the crystal quality.

Pyridine-Anchored Small Molecule Interlayer Enables Defect Passivation and Enhanced Carrier Transport for Perovskite Solar Cells.

Engineering of the interface between the perovskite and hole transport layer (HTL) has been crucial to achieving high performance. In this study, two interfacial materials, MN-CZ and CN-CZ, are designed by systematically regulating the group substitution site to study the relationship between spatial conformation and the passivation effect. The passivation groups of CN-CZ molecules exhibit a stronger "vector addition" effect, resulting in larger molecular dipoles and enhanced defect passivation and energy level regulation effects.

Negative family and interpersonal relationship are associated with centromedial amygdala functional connectivity alterations in adolescent depression.

The amygdala, known for its functional heterogeneity, plays a critical role in the neural mechanism of adolescent major depressive disorder (aMDD). However, changes in its subregional functional networks in relation to stressful factors remain unclear. We recruited 78 comorbidity-free, medication-naive aMDD patients and 40 matched healthy controls (HC) to explore changes in resting-state functional connectivity (FC) across four amygdala subregions: the centromedial nucleus (CM), the basolateral nucleus (LB), the superficial nucleus (SF), and the amygdalostriatal transition area (Astr).

A Child With Concomitant Neuroblastoma and IgA Nephropathy: A Case Report and Literature Review.

Advances in metabolomics profiling of pediatric kidney diseases: A review.

Pediatric renal diseases encompass a diverse array of pathological conditions, often engendering enduring ramifications. Metabolomics, an emergent branch of omics sciences, endeavors to holistically delineate alterations in metabolite compositions through the amalgamation of sophisticated analytical chemistry techniques and robust statistical methodologies. Recent advancements in metabolomics research within the realm of pediatric nephrology have been substantial, offering promising avenues for the identification of robust biomarkers, the elaboration of novel therapeutic targets, and the intricate elucidation of molecular mechanisms.
