Evolution and Conceptual Insights into the Geometric Phase of Light: A Comprehensive Review
This review presents a unified account of the geometric phase of light, linking its fundamental principles to diverse manifestations in polarization, spatial, and vector modes. By connecting theoretical frameworks with key experimental realizations, it reveals a coherent physical picture that deepens understanding and stimulates new directions in ...

The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Two methods for the optimization of chiral reflection by a metamaterial made of either GaP/Air or PMMA/Air interfaces are compared, showing approaches towards fast design exploration and high‐performance results: a neural‐network pipeline and a genetic algorithm. The structures considered are characterized by a periodic, chiral texturation with a shape

Reconfigurable Nanogap SERS for Multiscale Molecular Sensing on Curved Surfaces
Reconfigurable Au‐coated SMP nanocomposites enable adaptive SERS through reversible tuning of Au─Au nanogaps. Embedded AgNPs serve as photothermal triggers and reinforcements. Wide gaps facilitate macromolecule detection, while narrowed gaps enhance small‐molecule signals for reliable multiscale sensing on curved surfaces.

The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...

Computational methods for automated center determination in electron diffraction patterns
This study evaluates and compares automated methods for center detection in 2D diffractograms. The methods have been implemented in EDIFF, an open‐source user‐friendly Python package for the processing of electron diffraction patterns.Accurate center detection in electron diffraction patterns is critical for all subsequent processing of experimental ...

Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...
