Textile industries discharge a large quantity of colored wastewater which is harmful to the ecosystem. In this study, two kinds of dyes were investigated: the mono azo Acid Orange 7 (AO7) and diazo Reactive Green 19 (RG19). The photocatalytic degradation of single (AO7, RG19) azo dye and binary (AO7 and RG19 mixture) azo dye aqueous solutions was photocatalyzed by commercial titanium dioxide (T...

In this paper, we proposed the effects of Mo thickness on the properties of AZO/Mo/AZO multilayer thin films for opto-electronics applications. The structural, optical and electrical properties of AZO/Mo/AZO thin films were investigated. Optimization of the thin films coatings resulted with low resistivity of 9.98 × 10 Ω-cm, mobility of 12.75 cm/V-s, carrier concentration of 1.05 × 10 cm, maxim...

Abstract The accumulation of toxic chemical constituents in sludge and wastewater has fuelled an interest investigating efficient eco-friendly remediation approaches. In this study, a set bacterial samples were isolated from petroleum tested for their ability to degrade different aromatic pollutants, including azo dyes emerging pollutants. Although exhibiting differential specificity, all isola...

In this study, a hydrogen-based denitrification (HD) reactor was used to investigate the simultaneous treatment of nitrogen and decolorization in textile wastewater contaminated with organic matter. The operated two phases: without Despite short hydraulic retention time, HD system successfully removed all pollutants, including nitrate, nitrite, reactive black-5 dye chemical oxygen demand. unhin...

Photocatalytic degradations of azo dye (RR 180), pesticide (2,4-D) and antibiotic (enrofloxacin) in aqueous solutions were performed and compared by using pure ZnO and ZnO/TiO2 composite (at 1:1 ZnO to TiO2 mole ratio) catalysts in a self-supporting plate form. The plates were produced by tape casting of the constituent powder slurries and sintering at 600°C. Photocatalytic degradations of thes...

Electrospun materials, due to the possibility of design their properties, are suitable as supports for enzyme immobilization. Produced biocatalytic systems might be then apply in various reactions, including conversion pollutants. In our study, electrospun fibers made from nylon 6 was produced, modified and applied a support laccase immobilization by adsorption covalent binding. The with immobi...

In this study, indium-tin oxide (ITO)/Al-doped zinc oxide (AZO) composite films were fabricated by pulsed laser deposition and used as transparent contact layers (TCLs) in GaN-based blue light emitting diodes (LEDs). The ITO/AZO TCLs were composed of the thin ITO (50 nm) films and AZO films with various thicknesses from 200 to 1000 nm. Conventional LED with ITO (200 nm) TCL prepared by E-beam e...

BACKGROUND Role of renin-angiotensin aldosterone system (RAAS) in feline systemic hypertension is poorly understood. OBJECTIVES Examine plasma renin activity (PRA) and plasma aldosterone concentrations (PAC) in normotensive and hypertensive cats with variable renal function and in response to antihypertensive therapy. ANIMALS One hundred and ninety-six cats >9 years from first opinion pract...
