Determination of xanthophylls in egg yolk using a combination of spectrophotometric and diol phase high-performance liquid chromatography methods.

Normal-phase (NP) liquid chromatography is one of the most effective methods for separating isomers with sensitive structural features, including xanthophyll isomers. In this work, reverse-phase (RP) and NP liquid chromatography (LC), with silica gel and diol phase, respectively, were evaluated for the separation of xanthophyll isomers. The results showed that RP LC with monomeric C18 phase not only poorly separate all xanthophyll isomers in egg yolk but also requires additional sample preparation to eliminate triacylglycerols in egg yolk.

Acute Exposure to Polyethylene Microbeads and Effects on the Water Flea Moina Macrocopa.

Microplastics merit attention as they can be ingested by lower trophic organisms, transferred to the food web, and pose potential risks to higher trophic levels. This study investigated the accumulation and effects of polyethylene microbeads (PEMBs, 63-75 μm) on adult water flea Moina macrocopa (600-800 μm), an order-magnitude difference in size, as a result of acute exposure. The organisms were exposed to PEMBs in four treatments of 0 (the Control), 5, 50, and 500 mg PEMB/L for examining PEMB accumulation, survival and reproduction of the organisms after the 24- and 48-h exposures.

Electron-phonon coupling effect on the optical absorption of gated β-borophene.

This study addresses the effect of electron-phonon coupling (EPC) on the electro-optical properties of gated β-borophene. The focus is on how EPC influences the orbital hybridization of boron atoms, particularly within the Bariśic-Labbe-Friedel-Su-Schrieffer-Heeger framework, and considers the role of gate electrodes in this process. The results reveal a redshift in the optical spectrum only when there is positive feedback from one electrode on EPC.
