Stereodivergent Synthesis of C5‐α‐Substituted Linezolid Derivatives From D‐Mannitol and Structure–Antibacterial Activity Evaluation

Chirality, Volume 38, Issue 9, September 2026.
A stereodivergent route from D‐mannitol enables access to enantiopure C5‐α‐substituted linezolid analogues with full configurational control. Biological evaluation reveals that α‐substitution abolishes antibacterial activity irrespective of stereochemistry, establishing a strict steric limitation at C5 and highlighting the dominant role of substituent ...

Instrument-matrix based full-Stokes parameter direct retrieval for snapshot imaging polarimeter

Optics Express
Full-Stokes parameters of reflected lights provide rich information on a target’s polarization properties, making polarimetric imaging play a crucial role in numerous application fields of optic vision, where vast amounts of information are required. However, efficiently and accurately retrieving the full-Stokes parameter remains a challenging task, as

OBSERVING THE POLARIZED COSMIC MICROWAVE BACKGROUND FROM THE EARTH: SCANNING STRATEGY AND POLARIMETERS TEST FOR THE LSPE/STRIP INSTRUMENT

, 2020
Detecting B-mode polarization anisotropies on large angular scales in the Cosmic Microwave Background (CMB) polarization pattern is one of the major challenges in modern observational cosmology since it would give us an important evidence in favor of the inflationary paradigm and would shed light on the physics of the very early Universe.

A cross-instrument closure and polarimetric study for improving sub-millimeter polarimeter-radiometer ice cloud microphysics retrievals

Atmospheric Chemistry and Physics
Ice cloud microphysical properties, such as phase, shape, size and density, introduce significant uncertainties and biases that affect our understanding of how clouds influence weather and climate. The upcoming spaceborne sub-millimeter radiometers are expected to help in reducing the ice microphysics induced uncertainties in observations.
