"Die Erfindung von Anilin und anderen synthetischen Farbstoffen in der zweiten Hälfte des neunzehnten Jahrhunderts ist der Beginn einer neuen Epoche. Die von der noch jungen chemischen Industrie produzierten neuen Farben sind nicht nur leuchtender als die meisten der traditionellen Farbstoffe, sondern auch viel billiger. Sie verändern das Aussehen von Frauen auf den Straßen der modernen Stadt. Unter den ersten Medien, die diese Revolution bemerken und dokumentieren, sind Modezeitschriften, realistische Romane und impressionistische Gemälde. Der Beitrag zeigt, dass die strahlenden Farben der neuen Palette der impressionistischen Maler ein direkter Effekt der chemischen Industrie sind. </br></br>The invention of aniline and other synthetic dyes in the second half of the nineteenth century is the beginning of a new epoch. The new colors produced by the fledgling chemical industry are not only brighter than most of the traditional dyestuffs, but also much cheaper. They change the appearance of women on the streets of the modern city. Among the first media to notice and document this revolution are fashion magazines, realist novels, and Impressionist paintings. I argue that the bright colors on the new palette of Impressionist painters are a direct effect of the chemical industry. "

Photocatalytic Applications

Background: Textile industries discharge harmful synthetic dyes to nearby water sources. These colour effluents should be treated before discharge to reduce the toxicity caused by synthetic colours. Objective: To synthesize visible light active superstructures to reduce water pollution caused by textile industries. Methods: We have successfully synthesized ZnO/Dy/NiO hybrid nanocomposites using waste curd as fuel by a simple combustion method. The obtained material was able to reduce recombination and enhanced the photocatalytic degradation of organic pollutants. The as-synthesized material was characterized by XRD, absorption spectroscopy, FESEM, EDAX, etc. The obtained hybrid nanostructure was used as a photocatalyst for the degradation of methylene blue under sunlight, UV light as well as in dark. Comparative experiments were carried out with a variation of catalytic load, pH, dye concentrations, etc. for a better understanding of the performance of the catalyst at various conditions. Results and Conclusion: The ternary compound shows wide range of absorption by expanding absorption band both in UV and visible regions. ZnO/Dy/NiO hybrid nanocomposites performed well and showed uniqueness in the activity uder visible light.
