Measurement for high aspect ratio trenches based on inversion of pupil wavefront

High-aspect-ratio (HAR) trench structures are critical components in advanced semiconductor and integrated circuit manufacturing. However, achieving rapid, non-destructive, and high-precision measurement of their morphological parameters (depth and linewidth) remains a significan...

A Multiscale Theoretical Framework of Piezocatalysis

Abstract Piezocatalysis, which converts mechanical stimuli into chemical energy, holds significant promise for noninvasive medical therapies. In this process, ultrasonic frequency plays a dual role: it governs both the reaction rate and the electromechanical coupling efficiency,...

Data-driven control for orbit transition of piezoelectric energy harvesters under stochastic excitation

To address the tendency of bistable piezoelectric energy harvesting systems to remain trapped in low-energy intrawell oscillations and the difficulty of sustaining high-energy interwell motion under stochastic disturbances, this study proposes a data-driven event-triggered jump–d...

Anion Immobilization-Induced Enhancement of Li+ Transport at the Polymer Electrolyte–Separator Interface

Combustion characteristics and mechanisms of highly ignition-sensitive Al-Si-Li/PTFE energetic materials in low-pressure environments

As aerospace technologies advance globally, the application fields of energetic materials have expanded from ground and near-ground levels to high altitudes. The decrease in ambient pressure associated with increasing altitude significantly affects the ignition reliability and st...

Integrated retrieval of ocean surface wind and current fields from single-geometry SAR observations through a physically constrained Bayesian framework

Ocean surface winds and currents are coupled through air–sea interaction but are commonly retrieved independently from spaceborne synthetic aperture radar (SAR). For operational single-geometry SAR, simultaneous wind–current retrieval is underdetermined and remains reliant on bac...
