Environmental pollution may be considered one of the main problems affecting world population. As effluents from textile industries are largest representatives sources water bodies due to disposal colored compounds in environment. Microorganisms capable thriving wastewater exhibit metabolic machinery synthesize a wide variety enzymes and/or secondary metabolites industrial interest. The present...

The zero valent iron doped polypyrrole (Ppy/Fe) was synthesized via chemical oxidative polymerization method in diethylene glycol medium for the first time this study. characterization of Ppy and Ppy/Fe composites realized by using fourier transform infrared spectrometer (FTIR), UV-visible diffuse reflectance (DRS), scanning electron microscope (SEM), elemental dispersion X-ray analysis (EDX), ...

This work aims to study the photodegradation of Direct Blue 199 dye. The investigation was performed using titanium dioxide-based films immobilized on a polymethyl methacrylate (PMMA) polymer, by a promising low coast technique. The characterization of the films by X-ray diffractometry, fourier transform infrared spectroscopy, scanning electron microscopy, UV-Visible transmittance, and fluo...

While nature exploits folded biopolymers to achieve molecular recognition and catalysis, comparable abiological heteropolymer systems have been difficult to create. We synthesized and identified abiological peptoid heteroploymers capable of binding a dye. Using combinatorial synthesis, we constructed a library of 3400 amphiphilic 15-mer peptoids on an ultra-high-capacity beaded support. Individ...

A water soluble azo dye modified β-cyclodextrin polymer 4 was synthesized and used as a chemosensor for the detection of chlorinated phenols, model chlorinated by-products (CBPs) of water treatment for drinking purposes. The characterization of the intermediates and the azo dye modified β-CD polymer was done by UV/Vis Spectrophotometry, FT-IR and (1)H-NMR spectroscopies. The chlorophenols were ...

We present the synthesis and device characterization of new hole transport materials (HTMs) for application in solid-state dye-sensitized solar cells (ssDSSCs). In addition to possessing electrical properties well suited for ssDSSCs, these new HTMs have low glass transition temperatures, low melting points, and high solubility, which make them promising candidates for increased pore filling int...

The production of efficient, tunable, and switchable circularly polarized laser emission would have far reaching implications in optical communications or biophotonics. In this work, it is demonstrated the direct generation of circularly polarized (CP) laser emission in achiral and isotropic dye laser systems without the use of extracavity polarizing elements, and without resorting to chiral dy...

A method is proposed for separating light reflected from turbid media with a rough surface into a bulk and a surface component. Dye is added to the sample, thereby increasing absorption and canceling bulk scattering. The remaining reflected light is surface reflectance, which can be subtracted from the total reflectance of an undyed sample to obtain the bulk component. The method is applied to ...

In this paper, the fabrication and characterization of PDMS 2D-optical lenses are reported. These lenses are designed in order to improve the performance of fluorescent spectroscopy detection performed on a portable chip using optical fibers. The fabrication process of the PDMS layer is first detailed, and the patterns are then checked with a SEM. By comparing various interfacial structures, it...

In this research, nickel ferrite (NiFe2O4) nanoparticles (NFNs) are prepared through coprecipitation method, and applied for adsorption removal of a model organic pollutant, methyl orange (MO). The characterization of t...
