Influence of RF Power on Structural and Corrosion Properties of Sputter‐Deposited CrN Films

open access: yesMicroscopy Research and Technique, EarlyView.
Three‐dimensional AFM images of CrN/304SS films synthesized at varying RF power levels. Height distribution and the curves of the bearing area of CrN/304SS films synthesized at varying RF power levels. ABSTRACT This study examines the deposition of chromium nitride (CrN) films on 304 stainless steel (304SS) substrates using radio‐frequency (RF ...

Photonic Floquet–Bloch Oscillations Dominated by Floquet Gauge

open access: yesLaser &Photonics Reviews, EarlyView.
A new type of Bloch oscillations (namely, asymmetric Floquet–Bloch oscillations) whose evolution is biased along the evolution dimension is proposed and visually observed. The Floquet gauge can determine the light broadening to be biased toward the first or second half of the period. These findings reveal a new mechanism for wave packet revival and may

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems

open access: yesLaser &Photonics Reviews, EarlyView.
This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

pH‐Dependent Pitting Corrosion in Nickel Thin Films

open access: yesMaterials and Corrosion, EarlyView.
This study investigates pitting corrosion in nickel thin films under varying pH conditions and inhibitor presence. Surface defects and solution chemistry modulate pit formation, while simulations reveal metal redeposition driven by chemical potential gradients at the pit center.
