Published in 2017 at "Journal of Molecular Liquids"

DOI: 10.1016/j.molliq.2016.11.125

Abstract: Abstract The optical density, microstructure and electrical conductivity in nematic (ZhK440, 5CB and their mixtures) and cholesteric (the mixtures of ZhK440, 5CB with chiral M5) colloids with single-walled carbon nanotubes (CNTs) were studied. The azoxy… read more here.

Published in 2018 at "Nutritional Neuroscience"

DOI: 10.1080/1028415x.2017.1329976

Abstract: Objective: Macular pigment optical density (MPOD) – a non-invasive indicator of retinal xanthophylls and correlate of brain lutein – has been associated with superior cognitive function among adult populations. Given that lutein accumulation in the… read more here.

Published in 2021 at "Retina"

DOI: 10.1097/iae.0000000000003387

Abstract: Macular pigment optical density, measured by heterochromatic flicker photometry, increases in eyes with primary epiretinal membrane, proportionally to epiretinal membrane severity and, particularly, to outer nuclear layer thickening. Probably, epiretinal membrane contraction induces a foveal… read more here.

Published in 2023 at "Optics express"

DOI: 10.1364/oe.484093

Abstract: We theoretically propose a scheme to generate a strong continuous-variable quantum entangled light source in four-wave mixing (FWM) process by increasing the optical density of atomic medium. By properly choosing the input coupling field Rabi… read more here.

Published in 2020 at "Nutrients"

DOI: 10.3390/nu12040888

Abstract: Macular pigment (MP), which is composed of lutein/zeaxanthin/mezo-zeaxanthin, is concentrated in the central part of the retina, the macula. It protects the macula by absorbing short-wavelength light and suppressing oxidative stress. To evaluate whether MP… read more here.
