Operational stability of mixed Sn–Pb perovskite solar cells: Mechanisms, mitigation strategies, and perspectives

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review consolidates mechanisms and solutions for mixed Sn–Pb perovskite solar cells. It identifies Sn2+ oxidation, iodine generation, and interfacial defects as primary instabilities. It discusses progress in additives, interface passivation, alternative hole transport layers, and solvent engineering as well as future directions for achieving long‐

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Chiari I Malformation: Review and Update of Current Treatment Options

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The pathophysiology of Chiari malformation type I (CM‐I) is complex, involving structural abnormalities at the craniovertebral junction that result in herniation of the cerebellar tonsils through the foramen magnum. In this study, we aim to present and evaluate current treatment options for CM‐I, with a focus on evidence‐based clinical ...

Atherectomy With Multimodal Embolic Protection for Severely Calcified Femoropopliteal Lesions

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Severe calcification in femoropopliteal lesions remains a clinical challenge to achieve both the technical and long‐term success in endovascular therapy. Although atherectomy is an effective treatment for calcified lesions, it is associated with the risk of distal embolization, even with the use of embolic protection devices (EPDs), and ...

Recanalization of Thrombosed Atrial Flow Regulator in Failing Fontan: A Bridge to Transplant

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT We report the case of a 10‐year‐old boy (41 kg, 133 cm) with hypoplastic left heart syndrome (mitral and aortic atresia), who underwent staged palliation: Norwood‐Sano at 6 days, Glenn at 7 months, and Fontan completion at 3 years using a 16 mm non‐fenestrated extracardiac Gore‐Tex conduit.
