Chiral Phase Change Nanomaterials
Advanced Functional Materials, Volume 36, Issue 67, 20 August 2026.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Aggregate, Volume 7, Issue 8, August 2026.Accessible and chiroptically tunable helically chiral boron‐dipyrromethene dimer dyes enable the fabrication of solution‐processed isotropic neat thin films that retain sharp visible electronic circular dichroism signatures from solution. This platform establishes a direct molecule‐to‐material relationship and provides a robust foundation for the ...

Journal of Biophotonics, Volume 19, Issue 8, August 2026.Impact of cardiac and respiratory arrest on cardiac muscle tissue. Wistar rats were injected (on the left) either with cisatracurium to induce a respiratory arrest or lidocaine to induce a cardiac arrest (in the middle). Further, the pathophysiological changes developed and were assessed with linear polarization microscopy at 600–3000 nm wavelength ...

Aggregate, Volume 7, Issue 7, July 2026.A new chiral indaceno[1,2‐b:5,6‐b′]dithiophene bis‐thiophenylpropynone (IDT‐TPO) dye, which exhibits giant chiroptical properties (up to 18,000 mdeg) in drop‐casted and spin‐coated thin films upon simple aging, was deeply investigated by means of computational, microscopy, and spatially resolved chiroptical techniques.

Radio Science, Volume 61, Issue 6, June 2026.Abstract The ionosphere imposes coupled amplitude, phase, and polarization distortions on trans‐ionospheric Global Navigation Satellite System (GNSS) signals, reflecting the structure and dynamics of electron‐density irregularities. Classical weak‐scatter theory provides a mature framework for interpreting amplitude and phase scintillation, but these ...

Advanced Materials, Volume 38, Issue 25, 4 May 2026.Interferometric second‐harmonic generation (SHG) imaging reveals the ubiquitous formation of antiparallel domains in CVD‐grown 2D hexagonal boron nitride. By resolving lattice orientation and SHG phase, hidden domain structures and disorder become visible over large areas. The SHG intensity quantitatively tracks crystalline quality across growth routes,

Mueller matrix polarimetry using full Poincaré beams
Optics and Lasers in Engineering, 2019 Full Poincaré beams (FPBs) are proposed for polarimetric applications. Such beams present all states of totally polarized light across their transverse section at once and therefore can be considered as parallel polarization state generators. A simple setup, including a FPB as input light, has been designed and implemented to measure the Mueller matrix

Proposed Methods For Measuring and Interpreting Mueller Matrices in In Vivo Retinal Polarimetry [PDF]
, 2020 Mueller matrix polarimetry is the examination of how a sample transforms the polarization state of light. This requires probing the sample with input light of a variety of generated polarization states and analyzing the resulting output states, using a ...

Advanced Materials, Volume 38, Issue 16, 17 March 2026.In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

Preservation of Historically and Scientifically Important Geospatial Data From Venus
Earth and Space Science, Volume 13, Issue 3, March 2026.Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.
