Plasmon resonance optical tuning based on photosensitive composite structures [PDF]

, 2014
This paper reports a numerical investigation of a periodic metallic structure sandwiched between two quartz plates. The volume comprised between the quartz plates and the metallic structure is infiltrated by a mixture of azo-dye-doped liquid crystal. The

Potential and prospects of reductases in azo dye degradation: a review

The Microbe
Synthetic dyes, particularly azo dyes, pose environmental and health risks because of their toxicity and persistence. To reduce these negative effects, it is necessary to degrade and detoxify these dyes into simple, non-toxic substances.

Exploiting stored TiO2 electrons for multi-electron reduction of an azo dye methyl orange in aqueous suspension

Journal of Saudi Chemical Society, 2018
The mechanism of multi-electron reduction of methyl orange (MO) azo dye on TiO2 nanoparticles has been studied performing stopped flow technique. A multi-electron reduction of azo dye has been investigated.

Azo-hydrazone tautomerism of aryl azo pyridone dyes [PDF]

Hemijska industrija, 2013
In the last three or four decades disperse dyes derived from pyridones (in particular azo pyridone dyes) have gained in importance, and are widely used in various fields. These compounds have excellent coloration properties, and are suitable for the dyeing of polyester fabrics.

Concentration dependence of thermal isomerization process of methyl orange in ethanol [PDF]

, 2017
The thermal isomerization (TI) rates of methyl orange (MO) and 4-dimethylaminoazobenzene (DMAAB) in ethanol (EtOH) are measured. Usually TI rates of azobenzene dyes are known to be concentration independent.

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

Advanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Treatment of azo dyes in industrial wastewater using microbial fuel cells [PDF]

, 2014
Due to the extensive use of xenobiotic azo dyes in the colour industry and their proven mutagenic and cytotoxic nature, their treatment prior to discharge is essential and is legally enforced.

Quantification of Nitrite/Nitrate in Food Stuff Samples Using 2-Aminobenzoic Acid as a New Amine in Diazocoupling Reaction [PDF]

, 2011
2-Aminobenzoic acid has been used as an amine in diazocoupling reaction to form an azo dye in the quantification of nitrite/nitrate at trace level. The formed azo dye has an absorption maximum at 550 nm in aqueous phase, and the resulted dye can be ...
