Unveiling the Impact of C60–O2 Interaction on the Performance and Characterization of Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.

Rapid Design of Efficient Mn3O4‐Based Photocatalysts by Machine Learning and Density Functional Theory Calculations

Advanced Energy and Sustainability Research, EarlyView.
A rapid design strategy is presented for efficient Al‐doped Mn3O4‐based photocatalysts by integrating density functional theory calculations, machine learning (ML) modeling, and experiments. The optimized Al0.5Mn2.5O4/35 wt%‐Ag3PO4 heterojunctions achieved a 27‐fold improvement in methylene blue degradation under visible light compared to pristine ...

Maximum Principle and Application of Parabolic Partial Differential Equations

IERI Procedia, 2012
AbstractWe use the maximum principle in comparison principle and blowing up questions. In the last, we discuss the maximum principle of elliptic partial differential equation. By importing the strong maximum principle and Hopf lemma of boundary, and presents two results which are unknown before .And applied maximum to the problem of Poisson and the ...

Suppressed Thermal Conductivity in van der Waals Semiconductor SnS2 by Stacking Engineering

Advanced Energy and Sustainability Research, EarlyView.
Achieving low thermal conductivity is crucial for materials used for thermoelectric energy conversion. It is demonstrated that the lattice thermal conductivity of van der Waals semiconductor SnS2 can be significantly reduced by introducing 2H and 4H structures stacked along the c‐axis.

A unique case of commensalism: The beaver beetle Platypsyllus castoris (Leiodidae, Coleoptera) and its morphological adaptations

Journal of Morphology, Volume 284, Issue 1, January 2023., 2023
We document in detail the morphology of adults of the beaver beetle Platypsyllus castoris with modern techniques, and interpret evolutionary changes linked with the specific life style of the beetle in the fur of the beaver. Platypsyllus displays numerous structural specializations which ensure mechanical stabilization, firm anchorage on the host, and ...
