Optical Rotation—A Reliable Parameter for Authentication of Honey? [PDF]

open access: yesMolecules, 2022
The controversial question of whether optical rotation data can be used to distinguish floral from honeydew honey was investigated. Specific optical rotation angles were determined for 41 honey samples, including floral, honeydew, and adulterated honey ...

Unconventional specular optical rotation in the charge ordered state of Kagome metal CsV3Sb5 [PDF]

open access: yesNature Communications, 2023
Kagome metals AV3Sb5 (A = K, Cs, Rb) provide a rich platform for intertwined orders, where evidence for time-reversal symmetry breaking, likely due to the long-sought loop currents, has emerged in STM and muon spin relaxation experiments.

Deep learning-based method for analyzing the optically trapped sperm rotation [PDF]

open access: goldScientific Reports, 2023
Optical tweezers exert a strong trapping force on cells, making it crucial to analyze the movement of trapped cells. The rotation of cells plays a significant role in their swimming patterns, such as in sperm cells. We proposed a fast deep-learning-based

Chiral supramolecular assembly to enhance the magneto-optical rotation of organic materials [PDF]

open access: yesNature Communications
Connections between magnetic field induced optical activity and chirality have a rich and complicated history. Although the broken inversion symmetry of chiral molecules generates ‘natural’ optical activity, magnetic optical activity is generated by ...

Polarimetric Measurements of Surface Chirality Based on Linear and Nonlinear Light Scattering

open access: yesFrontiers in Chemistry, 2021
A molecule, molecular aggregate, or protein that cannot be superimposed on its mirror image presents chirality. Most living systems are organized by chiral building blocks, such as amino acids, peptides, and carbohydrates, and any change in their ...

Complexation of Boronic Acid with Chiral α-Hydroxycarboxylic Acids and the Ability of the Complexes to Catalyze α-Hydroxycarboxylic Acid Esterification

open access: yesMolecules, 2023
The complexation of boric acid (BA) with various α-hydroxycarboxylic acids (HCAs) was examined by analyzing the change in the optical rotation after the addition of BA to aqueous HCA solutions, and the catalytic properties of the complexes were examined ...
