water plays a vital and essential role in our ecosystem. this natural resource is becoming scarce, making its availability a major social and economic concern. use of a large variety of synthetic dyes in textile industries has raised an hazardous environmental alert. about 17 - 20% of freshwater pollution is caused by textile effluents. these effluents are recalcitrant to biodegradation and cau...

Laser dyes are organic chemicals whose systematic names are lengthy and confusing. Other names-some jargon, some trade-have come into everyday use, but there is no consistency, and sometimes research workers will have dyes from different suppliers that are identical in structure although different in name. This paper tabulates laser dyes by a characteristic identification number.

The paper presents a three-stage framework for assessment of fluorescent dyes as tracers for use within Municipal Solid Waste (MSW) landfills. The value of tracer testing as a means of determining leachate behaviour and guiding leachate management strategies is explained. In the first stage, the fluorescence spectra of 27 leachates were compared with 30 fluorescent dyes, to find those dyes for ...

A facile, solvothermal synthesis of mesoporous cerium oxide nanospheres is reported for the purpose of the photocatalytic degradation of organic dyes and future applications in sustainable energy research. The earth-abundant, relatively affordable, mixed valence cerium oxide sample, which consists of predominantly Ce7O12, has been characterized by powder X-ray diffraction, X-ray photoelectron a...

Mesoporous nanostructures represent a unique class of photocatalysts with many applications, including splitting of water, degradation of organic contaminants, and reduction of carbon dioxide. In this work, we report a general Lewis acid catalytic template route for the high-yield producing single- and multi-component large-scale three-dimensional (3D) mesoporous metal oxide networks. The large...

Azo dyes are widely prevalent environmental contaminants that are recalcitrant to biodegradation processes and have detrimental biological effects. Hence, exploring the novel microbial agents and to develop ecofriendly cost-effective process is pertinent for treatment of textile effluents. A fungal consortium comprising three strains Penicillium oxalicum SAR-3, Aspergillus niger SAR-6 and Asper...

As a new family of functional porous materials, conjugated polymers (CPPs) with tuneable porosities and molecular architectures show great potentials in adsorption, light harvesting, catalysis applications. This paper describes the incorporation strong visible-light absorbing BODIPY molecules into skeleton CPPs via Sonogashira coupling reactions. The obtained displayed integrated properties hig...
