XVI.—On artificial alizarin

Skeletal examination by alizarin staining.

A skeletal examination of fetuses is required in regulatory embryo-fetal development studies. This chapter describes a method of skeletal examination using alizarin staining. All fetuses are removed from the mother by caesarean section before birth. The fetuses are first examined externally. For larger species (rabbit and minipig), an internal examination can be performed on the fresh soft tiss...

Alizarin marking of whitefish, Coregonus lavaretus otoliths during egg incubation

Alizarin red S from 200 to 5000 mg L was used to mark the otoliths of whitefish embryos Coregonus lavaretus (L.) from 5 days after fertilization until shortly before hatching, to develop a method for evaluating the effect of stocking whitefish. Mark quality depended on developmental stage at the time of immersion. The best results were obtained when the otolith primordia had formed and had star...

Imaging the Ultrafast Photoelectron Transfer Process in Alizarin-TiO2.

In this work, we adopt a quantum mechanical approach based on time-dependent density functional theory (TDDFT) to study the optical and electronic properties of alizarin supported on TiO2 nano-crystallites, as a prototypical dye-sensitized solar cell. To ensure proper alignment of the donor (alizarin) and acceptor (TiO2 nano-crystallite) levels, static optical excitation spectra are simulated u...

Spectrophotometric determination of ceterizine hydrochloride with Alizarin Red S.

A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer. The chromogen being extractable with chloroform, could be measured quantitatively at 440 nm. All variables were st...
