Stabilization Strategies for Carbon Based Perovskite Solar Cells Under Light, Heat, and Humidity

open access: yesEcoEnergy, EarlyView.
Carbon‐based MA1−x(AVA)xPbI3/CsPbBr3 QD heterostructures fabricated under ambient conditions exhibit < 5% loss under ISOS‐D‐3 and reversible photo‐induced degradation, revealing the dual role of QDs in defect passivation and dynamic interfacial stabilization.

Forecasting heart failure: Seasonal alignment of heart failure outcomes in New York

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 819-831, April 2025.
Abstract Background Seasonal variations have been observed in heart failure (HF) hospitalization. Numerous explanatory mechanisms have been proposed, but no prior studies have examined potential contributors directly. Our objective was to identify specific factors that could contribute to seasonal variability using a large longitudinal dataset of HF ...

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...
