Application of extremophilic plant growth promoting bacteria (PGPB) and their enzymes in bioremediation have been received increasing interest due to eco-friendly nature effectiveness for bio treatment diverse industrial micro pollutants. In this work, the azo-dye decolorization potential halophilic PGPB Halomonas desertis G11 was evaluated optimized using central composite experimental design ...

Industrial development may result in the increase of environmental risks. The enzymatic transformation of polluting compounds to less toxic or even innocuous products is an alternative to their complete removal. In this regard, a number of different redox enzymes are able to transform a wide variety of toxic pollutants, such as polynuclear aromatic hydrocarbons, phenols, azo dyes, heavy metals,...

Atmospheric aerosol pollutants are considered for the first time durability evaluation of non-metallic photovoltaic materials on example pristine and Al2O3-encapsulated Al-doped zinc oxide (AZO) window layers. The AZO samples were exposed to a varied temperature humidity cycle, completed or not by daily deposition (NH4)2SO4 NaCl aerosols, typical in rural marine environments, respectively. with...

This paper introduces a new reagent N-phenylbenzylamine for determination of nitrite in water and aqueous solutions. The reagent in the acidic medium coupled with diazotized dapsone to form the azo dye. The reaction provides a sensitive and reproducible determination of nitrite without special modifications of reaction conditions. The detection limit is 0.07 μg.ml, and linear range 0.1-2.0 μg.m...

–A novel series of 2-phenyl-5-sulpha/substituted-3-phenyl substituted azo indoles have been synthesized and tested as an antifertility activity in mature albino mice. The tested compounds showed significant antifertility activity. Keywords––Synthesis, Antifertility activity, Indore, Azo indoles, chemical analysis.

Comparative study of the of azo Dyes (as a class important organic pollutants photodegradation process) in aqueous solution employing H2 O2 /UV and K2 S2 O8 /UV systems in a photochemical reactor were investigated. Lead zirconate titanate [Pb (Zr0.58Ti0.42) O3 ] (PZT) nanocatalyst was synthesized via the sol-gel method. Then, photocatalytic properties of dopant type on PZT were determined in a ...

Lignocellulose facilitates the fungal oxidization of recalcitrant organic pollutants through the extracellular ligninolytic enzymes induced by lignin in wood or other plant tissues. However, available information on this phenomenon is insufficient. Free radical chain reactions during lignin metabolism are important in xenobiotic removal. Thus, the effect of lignin on azo dye decolorization in v...

Azo dyes are produced in very large quantities and used as reactive dyes by the cotton industry. They are very stable and resistant to chemical processes. Therefore, their removal from industrial effluents by conventional methods (mechanical screening, sedimentation, biological treatment, biofilters) alone is usually not very effective. This problem can be solved by combining the conventional t...

The laser-initiated thermal (optothermal) switching of cholesteric liquid crystals (CLCs) is characterized by using different azobenzene (Azo) derivatives and laser wavelengths. Under 405-nm laser irradiation, Azo-doped CLCs undergo phase transition from cholesteric to isotropic. No cis-to-trans photoisomerization occurs when the 405-nm laser irradiation is blocked because only a single laser i...

In this work, we investigated the use of a homogeneous Al-doped zinc oxide (AZO) buffer layer to improve the performance of an organic light-emitting diode (OLED) device fabricated on an AZO anode. For this, 10-nm-thick AZO buffer layers with Al doping concentrations of 3.1, 4.1, and 5.1 at % were grown on 140-nm-thick AZO anode films containing 2.1 at % Al by atomic layer deposition. The elect...
