X-ray Polarimetry

open access: yes, 2010
Due to the advent of a new generation of detectors, X-ray polarimetry promises to join X-ray imaging, spectroscopy and timing as one of the main observational techniques in high energy astrophysics. This has renewed interest in the field, and indeed several polarimetric missions have recently been proposed.

Reversible Hydration Tuning of Polar Order and Large Nonlinear Optical Response in a 2D van der Waals Crystal, LiInP<sub>2</sub>S<sub>6</sub>. [PDF]

open access: yesAdv Mater
Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Ultrathin Freestanding BiFeO<sub>3</sub> Membranes Grown by Pulsed Laser Deposition. [PDF]

open access: yesSmall
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

X-Ray Polarimetry as a Tool to Constrain Orbital Parameters in X-Ray Binaries

open access: yesThe Astrophysical Journal
X-ray binary systems consist of a companion star and a compact object in close orbit. Thanks to their copious X-ray emission, these objects have been studied in detail using X-ray spectroscopy and timing.

Highly Chiral MoS<sub>2</sub> Flakes With Redox-Active Centers for Spin Selective Water Oxidation. [PDF]

open access: yesSmall Sci
The chiral‐induced spin selectivity effect was realized exploited in Ni‐doped, intrinsically chiral 2D MoS2 flakes to suppress H2O2 production and enhance water oxidation kinetics during water splitting. We propose a hydrothermal synthesis route for highly chiral two‐dimensional flakes of MoS2 doped with single nickel atoms (Ni:MoS2) for spin ...

X-ray polarimetry and its application to strong-field quantum electrodynamics

open access: yesHigh Power Laser Science and Engineering, 2023
Polarimetry is a highly sensitive method to quantify changes of the polarization state of light when passing through matter and is therefore widely applied in material science.

Polarized Light Microscopy for Quantitative Assessment of Sarcomere-Scale Structural Order in Cardiac Tissue. [PDF]

open access: yesJ Biophotonics
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 ...
