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.

Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

Light‐Modulated Exchange Bias in Multiferroic Heterostructures

open access: yesElectron, EarlyView.
In this article, exchange bias and magnetization are modulated with visible light at room temperature in PMN‐PZT/FeGa/IrMn multiferroic heterostructures. Photostrictive effect is the main mechanism leading to the modulation of magnetic anisotropy and interfacial exchange bias coupling between the ferromagnetic and antiferromagnetic layers.

Heterogeneous Impact of Green Bonds on Environmental Quality: A Cross‐Country Analysis of the Load Capacity Factor

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study investigates the impact of green bonds on environmental sustainability for a panel of 15 countries from 2014 to 2024, using the load capacity factor (LCF) as the main proxy for environmental quality, with biocapacity, ecological footprint, and CO2 emissions per capita used as additional environmental indicators.

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.
