Hierarchical Fluorinated Polymer Separator Design Mitigating Bilateral Ionic Crosstalk in Aqueous Batteries

Advanced Energy Materials, EarlyView.
Aqueous zinc‐ion batteries suffer from rapid decay under practical conditions due to bilateral Zn2+/Mn2+ ionic crosstalk, a system‐level failure mechanism. We develop a hierarchical fluorinated polymer separator that regulates ion fluxes and stabilizes both electrodes simultaneously. This strategy enables extended cycle life while maintaining capacity,

Testing an in-line digital holography ‘inverse method’ for the Lagrangian tracking of evaporating droplets in homogeneous nearly isotropic turbulence

, 2012
An in-line digital holography technique is tested, the objective being to measure Lagrangian three-dimensional (3D) trajectories and the size evolution of droplets evaporating in high-Reλ strong turbulence.

Clinically Informed Intelligent Classification of Ovarian Cancer Cells by Label‐Free Holographic Imaging Flow Cytometry

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quantitative phase maps of single cells recorded in flow cytometry modality feed a hierarchical architecture of machine learning models for the label‐free identification of subtypes of ovarian cancer. The employment of a priori clinical information improves the classification performance, thus emulating the clinical application of liquid biopsy during ...

Speckle Reduction in Digital Holography by Fast Logistic Adaptive Non-Local Means Filtering

Photonics
Digital holography is a promising imaging technology. However, there is speckle noise in the reconstructed image of a digital hologram. Speckle degrades the quality of the reconstructed image.

Magnetic Solitons and Thickness‐Dependent Magnetization Reversal in Interconnected Helical Nanowire Arrays

Advanced Physics Research, EarlyView.
3D magnetic interconnected helical nanowire arrays are fabricated and shown to host a variety of magnetic solitons. It is observed that the magnetic reversal mechanism is repeatable and not stochastic for a consistent direction of the applied field. Additionally, changing the shape of the nanowire arrays alters the magnetic solitons that form, but the ...

Extending the Depth of Field beyond Geometrical Imaging Limitations Using Phase Noise as a Focus Measure in Multiwavelength Digital Holography

Applied Sciences, 2018
Digital holography is a well-established technology for optical quality control in industrial applications. Two common challenges in digital holographic measurement tasks are the ambiguity at phase steps and the limited depth of focus.

Label‐Free Holographic Imaging Flow Cytometry With Deep‐Learning‐Based Detection and Classification of Thousands of Cells Per Second

Cytometry Part A, EarlyView.
ABSTRACT We present a new end‐to‐end neural network approach for real‐time biological cell detection and classification via label‐free quantitative imaging flow cytometry based on digital holography, offering a comprehensive representation of cellular structures without the need for chemical cell staining. In contrast to previous studies, our method is
