Six ionic liquid (IL)-modified dyes were synthesized and characterized. Compared to the methyl red and methyl orange, these IL-modified [MR](-)- or [MO](-)-based dyes exhibit lower melting points and enhanced solubility, and can be used as sensitive indicators towards free proton in both aqueous and non-aqueous solutions. This work also supplies a new concept of developing novel modified materi...
In this research we have developed a treatment method for textile wastewater by TiO2/SiO2-based magnetic nanocomposite. Textile wastewater includes a large variety of dyes and chemicals and needs treatments. This manuscript presents a facile method for removing dyes from the textile wastewater by using TiO2/SiO2-based nanocomposite (Fe3O<su...
Seventeen commonly used dyes and 16 of their metabolites or derivatives were tested in the Salmonella-mammalian microsome mutagenicity test. Mutagens active with and without added Aroclor-induced rat liver microsome preparations (S9) were 3-aminopyrene, lithol red, methylene blue (USP), methyl yellow, neutral red, and phenol red. Those mutagenic only with S9 activation were 4-aminopyrazolone, 2...

The involvement of Ca(2+) on phytochrome-controlled nyctinastic closure in Albizzia lophantha has been studied by testing the effect of the calcium ionophore 6S-[6alpha(2S(*),3S(*)),8beta(R(*)),9beta,11alpha]-5- methyl-amino)-2-[[3,9,11-trimethyl-8-[-1-methyl-2-oxo-2-(1H-pyrrol-2-yl) ethyl]-1,7-dioxaspiro[5.5]-undec-2yl] methyl]-4-benzoxazolecarboxylic acid (A23187) and the intracellular calciu...
تعدادی از کمپلکس های باز شیف محلول در آب n,n?-bis{5[(triphenylphosphoniumchloride)-methyl]salicylidine}-4-methyl-o-phenylenediamine]copper(??) ([cu(5-ch2pph3-4-methyl-1,2-salophen)](clo4)2), n,n?-bis{5-[(triphenylphosphoniumchloride)-methyl]salicylidine}-4-methyl-o-phenylenediamine]nickel(??) ([ni(5-ch2pph3-4-methyl-1,2-salophen)](clo4)2), و کمپلکس های نانو باز شیف محلول در آب n,n?-bis{5...
In this work, chitosan and carboxy methyl cellulose biopolymers were used as gelling agents in composition of electrolyte of dye sensitized solar cells. The effect of both biopolymers on performance of dye sensitized solar cell were investigated by adding the same amounts of two biopolymers to the liquid electrolytes composed of ox/red couple of I-/I3- with similar concentrations. The electroch...
Searching for virulence marking tests for Mycobacterium tuberculosis, Dubos and Middlebrook reported in 1948 that in an alkaline aqueous solution of neutral-red, the cells of the virulent H37Rv M. tuberculosis strain fixed the dye and became red in color, whereas the cells of the avirulent H37Ra M. tuberculosis strain remained unstained. In the 1950 and 1960s, fresh isolates of M. tuberculosis ...
