Transfer learning-based fault diagnosis of wind turbine high-speed shaft bearings using CWRU pretraining and public run-to-failure data

Fault diagnosis of wind turbine high-speed shaft bearings (HSSBs) is hindered by the distribution gap between laboratory data and field signals, and by the lack of labeled run-to-failure recordings. This study proposes a three-stage transfer learning framework to address both pro...

Vaporization-Guided Morphology Evolution Enables Precision Control in Blade-Coated Organic Solar Cells

Abstract Controlling the morphology evolution of blade-coated bulk-heterojunction active layers is crucial for achieving high-efficiency organic solar cells (OSCs), yet remains challenging because rapid solvent evaporation and unbalanced donor–acceptor aggregation often lead to p...
