Introduction of glyphosate resistance into crops through genetic modification has revolutionized crop protection. Glyphosate is a broad-spectrum herbicide with favorable environmental characteristics and effective broad-spectrum weed control that has greatly improved crop protection efficiency. However, in less than a decade, the utility of this technology is threatened by the occurrence of gly...

Abstract The modification of cotton fabrics with water-soluble cationic copolymers for salt-free dyeing applications reactive dyes is explored in the present work. To this end, a family bifunctional was designed through chemical poly(4-vinyl benzyl chloride), PVBC, triethylamine, TEAM. These were applied onto aqueous alkaline solutions at moderate temperature (60 °C). successful verified charac...

Liposome is colloidal, vesicular structures capable of targeting to specific sites. Evans blue dye (hydrophilic dye) were formulated in liposomes using phosphatidyl choline, cholesterol and those liposomes were modified using surfactants surfactants span 20 , span 40 , span 80 or tween 80 at various molar ratio and optimized for its stable vesicular formation. The particle size and FTIR analysi...

Microbial fuel cells (MFCs) represent an emerging technology that focuses on power generation and effluent treatment. This review compiles articles related to MFCs using azo dye as the substrate. The significance of the general components in MFCs and systems of MFCs treating azo dye is depicted in this review. In addition, degradation of azo dyes such as Congo red, methyl orange, active brillia...

Abstract A new green approach was developed in the present study to pre-activate and modify cellulose/polyester blended fabrics surfaces using atmospheric plasma, as a alternative non-eco-friendly conventional chemical modification processes, followed by post-dyeing/functional finishing obtain high value-added, multifunctional, protective colored fabrics. The obtained results demonstrated that ...

An efficient synthetic protocol to functionalize the cyanoacrylic acid anchoring group of commercially available MK-2 dye with a highly water-stable hydroxamate anchoring group is described. Extensive characterization of this hydroxamate-modified dye (MK-2HA) reveals that the modification does not affect its favorable optoelectronic properties. Dye-sensitized solar cells (DSSCs) prepared with t...

ZnO and TiO2 nanoparticles wereimpregnated with merbromin dye and used as modified photocatalysts for degradation of phenol. Dye-modified ZnO and TiO2 showed significantly higher photocatalytic activity than neat ZnO and TiO2 under visible light illumination. Moreover, the prepared dye-modified ZnO showed superior photocatalytic efficiency in degrad...
