Five hundred-nanometer-thick ZnO-based textured polycrystalline films consisting of 490-nm-thick Al-doped ZnO (AZO) films deposited on 10-nm-thick Ga-doped ZnO (GZO) films exhibited a high Hall mobility (μ H) of 50.1 cm(2)/Vs with a carrier concentration (N) of 2.55 × 10(20) cm(-3). Firstly, the GZO films were prepared on glass substrates by ion plating with dc arc discharge, and the AZO films ...

The present study investigated the effect of Azomite (AZO) on growth performance, nutrient utilisation, and bone mineralisation broilers fed low protein diet. A total number 180 one-day-old male chicks were randomly distributed to three treatment groups having six replicates 10 birds each. Experimental diets included; positive control (PC) with 21.5% CP (starter) 19.0% (finisher), negative (NC)...

The photocatalytic degradation of two commercial textile azo dyes, namely C.I Reactive Black 5 and C.I Reactive Red 239, has been studied. TiO(2) P25 Degussa was used as catalyst and photodegradation was carried out in aqueous solution under artificial irradiation with a 125 W mercury vapor lamp. The effects of the amount of TiO(2) used, UV-light irradiation time, pH of the solution under treat...

UNLABELLED Azo dyes, which re characterized by azo bonds, are a predominant class of colorants used in tattooing, cosmetics, foods, textile and consumer products. Laccases (EC 1.10.3.2), lignin peroxidases (EC 1.11.1.14) , Azo reductases (EC 1.7.1.6) of different micro organisms are mainly useful for the development of biodegradation systems as they catalyse reductive cleavage of azo groups (-N...

A new preparation method of polymer dyes was developed to improve both the grafting degree of the azo dyes onto O-carboxymethyl chitosan (OMCS) and the water solubility of prepared polymer dyes. Firstly, the coupling compound of two azo edible colorants, sunset yellow (SY) and allura red (AR), was grafted onto OMCS, and then coupled with their diazonium salt. The chemical structure of prepared ...

In this data article, we introduce data acquired from new adsorbent, bi-metalized chitosan particle that is successfully synthesized and applied to remove the orange II dye, an azo dye, from textile wastewater. The adsorbent was meso- and macro-porous material with BET surface area of 12.69 m(2)/g and pHzpc 6.6. The simulated textile-wastewater can be significantly treated using a relatively lo...

Push-pull bithienylpyrrole-based azo dyes exhibit thermal isomerisation rates as fast as 1.4 μs in acetonitrile at 298 K becoming, thus, the fastest neutral azo dyes reported so far. These remarkably low relaxation times can be transferred into liquid-crystalline matrices enabling light-triggered oscillations in the optical density of the final material up to 11 kHz under ambient conditions.

the main objective of this study was to investigate the effi ciency of biological treatmentof azo dye-containing wastewater with a sequencing batch reactor system, followed by ultrafi ltration.the performance of the system was quantifi ed by measuring the chemical oxygen demand and azo dyeconcentration. the biodegradation was carried out under combined alternating anaerobic and aerobiccondition...

At the concentrations usually employed as a Ca2+ indicator, arsenazo III undergoes a one-electron reduction by rat liver microsomes to produce an azo anion radical as demonstrated by electron spin resonance spectroscopy. Either NADH or NADPH can serve as a source of reducing equivalents for the production of this free radical by rat liver microsomes. The steady state concentration of the azo an...
