Polyphosphate gel/methyl orange supramolecular composites

Optical Materials, 2004
The aims of this work were to investigate theoretically the optical properties of methyl orange (MO) and the synthesis of new supramolecular composites based on the incorporation of this dye in an aluminum polyphosphate gel network. The theoretical methodology was based in semiempirical (AM1 and INDO/S-CI) and ab initio (3-21G*) methods.

Acridine Orange—Methyl Green Fluorescent Staining of Nucleoli

Stain Technology, 1981
The staining of nucleoli with the fluorescent dye acridine orange following by counter-staining with methyl green differentially stained nucleoli in both plant and animal cells. The nucleoli fluoresced as bright structures highlighted against the quenched fluorescence of the chromatin. This technique provides a simple and highly reproducible method for

Adsorption of Methyl Orange on Starches

Journal of Food Science, 1991
ABSTRACT Adsorption characteristics of methyl orange were investigated on kudzu, sweet potato, corn, rice, wheat, potato and snake gourd starches. No adsorption of methyl orange, an anionic dye, was observed on potato starch and snake gourd starch because of the presence of phosphate esters. Adsorption isotherms were found to fit both

Surface activity of methyl orange

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1979
The aggregation of methyl orange in aqueous acidic solutions is accelerated by enlarging either the gas–liquid or the glass–liquid interface and occurs heterogeneously.The subsequent surface activity of methyl orange in acidic solutions is confirmed by surface tension measurements.

Fluorescence Spectral Properties of Methyl Orange in Homogeneous Media

Journal of Fluorescence, 2021
The methyl orange [C14H14N3SO3Na], an azo dye exhibited strong emission and large Stokes shift in various solvents, and the largest shift (Δλ = 125.51nm or Δν = 9297cm-1) was obtained in the water. The UV-visible spectra of the dye showed the absorption in the range (33,333 - 20,000) cm-1.

In situ preparation of g-C3N4/Bi4O5I2 complex and its elevated photoactivity in Methyl Orange degradation under visible light.

Journal of Environmental Science, 2020
A graphite carbon nitride (g-C3N4) modified Bi4O5I2 composite was successfully prepared in-situ via the thermal treatment of a g-C3N4/BiOI precursor at 400°C for 3 hr. The as-prepared g-C3N4/Bi4O5I2 showed high photocatalytic performance in Methyl Orange

THE ADSORPTION OF METHYL ORANGE BY LYSOZYME

Canadian Journal of Biochemistry and Physiology, 1954
Adsorption isotherms for methyl orange on lysozyme at ionic strengths varying from 0.001 to 0.05, pH 5.5, are sigmoid. Increasing ionic strength shifts the inflection point of such isotherms to higher free anion concentrations. Binding of one methyl orange anion to a lysozyme molecule in 0.05 M acetate, pH 5.5, facilitates adsorption of nine others ...

Degradation of methyl orange using bismuth oxide

International Conference on Advanced Nanomaterials & Emerging Engineering Technologies, 2013
Bismuth oxide is prepared by a simple chemical route and it crystallizes in the monoclinic crystal system. The measured optical band gap value of 2.694(1) eV supported that the prepared bismuth oxide can be used as a visible light photocatalyst.

Synthesis of methyl orange using ionic liquids

Tetrahedron Letters, 2003
Abstract Two ionic liquids were synthesized, each system consisting of the 1-hexyl-3-methylimidazolium ion ([hmim]+) as the cation and either hexafluorophosphate ([PF6]−), or perchlorate ([ClO4]−) as the anions. This study involves the synthesis of methyl orange (4-[[(4-dimethylamino)phenyl]-azo] benzene sulfonic acid sodium salt) using the ionic ...

Photoinduced changes in methyl orange polyimide layers

Optical Materials, 1996
Abstract Photoinduced changes in methyl orange/polyimide layers are investigated by dichroic, holographic and z -scan measurements. Demonstrated is a substantial difference between the erasure kinetics of scalar and polarization holographic recording.
