Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

Energy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Trace MA+ Accelerates the Degradation of Perovskite Solar Cells at Elevated Temperatures

Information &Functional Materials, EarlyView.
We investigate how the A‐site cation influences the morphology and optoelectronic properties of perovskite films, and consequently, the operational stability of devices under continuous light illumination at elevated temperature. ABSTRACT Methylammonium (MA+) is the most widely adopted A‐site cation for high‐efficiency perovskite solar cells.
