Roles of 2D halide perovskites in 2D/3D heterojunctions for high‐performance perovskite solar cells

open access: yesBulletin of the Korean Chemical Society, EarlyView.
This review establishes a design framework for two‐dimensional (2D)/three‐dimensional (3D) perovskite heterojunctions, redefining the 2D perovskite layer as an active semiconductor component. We classify 2D structures by spacer chemistry and analyze their roles within the heterojunction.

ESG Performance, Debt Financing, and R&D Output: Evidence From the Healthcare Sector

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid growing calls for sustainability in the healthcare sector, this study examines how and under what conditions environmental, social, and governance (ESG) performance influences research and development (R&D) output. Although existing studies suggest that ESG performance enhances R&D output, the financial mechanisms that enable or constrain

Recent Strategies Toward Durable and Ion‐Tolerant Transition Metal‐Based Electrocatalysts in Seawater Electrolysis

open access: yesCarbon Energy, EarlyView.
Recent strategies address these challenges through ion‐specific regulation, encompassing chloride‐tolerant and chloride‐regulating anodes together with cathode designs that suppress OH− accumulation and Mg2+/Ca2+ coupling. This ion‐management‐oriented framework provides general guidelines for achieving stable, selective, and scalable seawater ...
