It has been shown that changes in selective reflection spectra are stronger at higher temperatures close to the transition point to isotropic phase. Optical density increases linearly with quercetin concentration and descreases with temperature, with sharp fall at the transition to isotropic phase. Such behavior is not conventional and can be used as a characteristic for interaction of liquid crystal with quercetin. Product Description popup.authors Ващенко О.В.
