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...

A review of the literature on the mutagenicity of textile dye products is presented in this article. This review discusses genetic hazards associated with the production and use of textile dyes throughout the world. Mutagenicity of azo and non azo dyes has been considered due to extensive recent data on the carcinogenicity and mutagenicity of this group of dyes. In addition, a section on Salmon...

The determination of dyes present in illicit pills is shown to be useful and easy-to-get information in strategic and tactical drug intelligence. An analytical strategy including solid-phase extraction (SPE) thin-layer chromatography (TLC) and capillary zone electrophoresis equipped with a diode array detector (CZE-DAD) was developed to identify and quantify 14 hydrosoluble, acidic, synthetic f...

VoltageFluor (VF) dyes have the potential to measure voltage optically in excitable membranes with a combination of high spatial and temporal resolution essential to better characterize the voltage dynamics of large groups of excitable cells. VF dyes sense voltage with high speed and sensitivity using photoinduced electron transfer (PeT) through a conjugated molecular wire. We show that tuning ...

objective: one of the major problems of all ceramic restorations is their probable fracture against the occlusal force. the aim of the present in-vitro study is was to compare the effect of two marginal designs (chamfer & shoulder) on the fracture resistance of zirconia copings, cercon (cad/cam). materials and methods : this in vitro study was done with single blind experimental technique. one ...

New applications have recently led to an increased interest in near infrared (NIR) dyes. Both, strong NIR absorption and fluorescence emission are important phenomena. While fluorescence is exploited especially for labelling purposes in microscopy, NIR absorption has a broad range of applications mainly in material science. Examples of growing fields of interest are NIR light emitting diodes an...

fe3o4 magnetic nanoparticles modified with 1-octyl-3-methylimidazolium bromide([c8mim]-fe3o4) were used for the removal of reactive red 141 (rr141) and reactive yellow 81 (ry81) as model azo dyes from aqueous solution. the mean size and the surface morphology of the nanoparticles were characterized by tem, xrd and ftir techniques. adsorption studies of two dyes were performed under different ex...
