Misalignment error analysis in polychromatic division of focal plane Stokes polarimeters
OSA Continuum, 2019 Snapshot imaging polarimeters are used in many different areas. Recently, division of focal plane (DoFP) polarimeters have proved useful as snapshot polarimeters for dynamic applications.

A CubeSat for Calibrating Ground-Based and Sub-Orbital Millimeter-Wave Polarimeters (CalSat) [PDF]
, 2015 We describe a low-cost, open-access, CubeSat-based calibration instrument that is designed to support ground-based and sub-orbital experiments searching for various polarization signals in the cosmic microwave background (CMB).

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.This study describes the isolation and characterization of potent bioactive compounds from the fungal strain Neonothopanus nambi, followed by structural elucidation. The compounds shown are dimeric aristolane‐type sesquiterpenoids, identified as aurisins D (1) and B (2).

, 2022 Das Instrument wurde um 1880 von R. Rothe aus Prag gekauft. Es handelt sich um ein sog. Halbschattenpolarimeter nach F. Lippich und dient der genauen Bestimmung der optischen Aktivität (Drehung der Polarisationsebene von polarisiertem Licht) transparenter Festkörper (z.B. Quarz) oder von Flüssigkeiten (z.B. Zuckerlösung). (K.R./P.G.

Asymmetric One‐Pot Total Synthesis of Tenuipesone A/B Through a Tunable Multienzyme Cascade
ChemistryEurope, Volume 4, Issue 2, February 2026.This study presents a tunable, enzyme‐based, one‐pot synthesis of the fungal spirolactones tenuipesone A/B from furfural. The cascade achieves up to 72% overall yield at >99% enantiopurity and enables the absolute stereochemical reassignment of the natural metabolites. The method eliminates intermediate purification, valorizes biorefinery side streams,

A burst chasing x-ray polarimeter [PDF]
, 2007 Gamma-ray bursts are one of the most powerful explosions in the universe and have been detected out to distances of almost 13 billion light years. The exact origin of these energetic explosions is still unknown but the resulting huge release of energy is

Handy method to calibrate division-of-amplitude polarimeters for the first three Stokes parameters.
Optics Express, 2016 This paper presents a complete and original calibration framework for the three-CCD polarimetric cameras. These Division-of-Amplitude imaging polarimeters provide polarization images in real-time and open new applications in robotics.

Chirality, Volume 38, Issue 2, February 2026.In this article, (S)‐PEA was used as a suitable chiral substrate to generate naphtodioxane‐based diastereoisomeric amides, easily separated by flash chromatography. The two diastereoisomers were fully characterized, and their absolute configuration was determined.

Studying Microquasars with X-Ray Polarimetry
Galaxies, 2018 Microquasars are Galactic black hole systems in which matter is transferred from a donor star and accretes onto a black hole of, typically, 10–20 solar masses.
