Dyes And Pigments

Colour is one of the elements of nature that makes human life more aesthetic and fascinating in the world. Plants, animals, and minerals have been used as primary sources for colourants, dyes or pigments since ancient times. In our daily life, we know about many substances which have specific colours. These are the substances which are used as colourants i.e.; colour imparting species. Both dyes and pigments are coloured as they absorb only some wavelength of visible light. Their structures have Aryl rings that have delocalized electron systems. These structures are said to be responsible for the absorption of electromagnetic radiation that has varying wavelengths, based upon the energy of the electron clouds. Dyes are coloured organic compounds that are used to impart colour to various substrates, including paper, leather, fur, hair, drugs, cosmetics, waxes, greases, plastics and textile materials. A Dye is a coloured compound due to the presence of chromophore and its fixed property to the acid or basic groups such as OH, SO3H, NH2, NR2, etc. The polar auxochrome makes the dye water-soluble and binds the dye to the fabric by interaction with the oppositely charged groups of the fabric structure. Pigments are organic and inorganic compounds which are practically insoluble in medium in which they are incorporated. Dyes and pigments are the most important colourants used to add colour or to change the colour of something. They are widely used in the textile, pharmaceutical, food, cosmetics, plastics, paint, ink, photographic and paper industries. This chapter is devoted to the structure and properties of dyes and pigments.

Since ancient times, the need for healthy water has resulted in the development of various kinds of water supply systems. From early history, civilizations have developed water purification devices and treatment methods. The necessity for fresh water has influenced individual lives as well as communities and societies. During the last two hundred years, intensive and effective efforts have been made internationally for sufficient water quantity and quality. At the same time, human life expectancy has increased all over the globe at unprecedented rates. The present work represents an effort to sketch out how water purity and life expectancy have entangled, thus influencing one another. Water properties and characteristics have directly affected life quality and longevity. The dramatic increase in life expectancy has been, indisputably, affected by the improvement in water quality, but also in other concomitant factors, varying temporally and spatially in different parts of the world throughout the centuries. Water technologies and engineering have an unequivocal role on life expectancy. In some cases, they appear to have taken place earlier than the progress of modern medicine. Among these, improved sanitation, personal hygiene, progress in medicine, and better standards of economic living have played the greatest roles.

This review focuses on the ability of some natural antioxidant molecules (i.e., hydroxycinnamic acids, coumarin-3-carboxylic acid, quercetin, luteolin and curcumin) to form Al(III)- and Fe(III)-complexes with the aim of evaluating the coordination properties from a combined experimental and theoretical point of view. Despite the contributions of previous studies on the chemical properties and biological activity of these metal complexes involving such natural antioxidants, further detailed relationships between the structure and properties are still required. In this context, the investigation on the coordination properties of Al(III) and Fe(III) toward these natural antioxidant molecules might deserve high interest to design water soluble molecule-based metal carriers that can improve the metal’s intake and/or its removal in living organisms.

Water soluble organic molecular pollution endangers human life and health. It becomes necessary to develop highly stable noble metal nanoparticles without aggregation in solution to improve their catalytic performance in treating pollution. Polyethyleneimine (PEI)-based stable micelles have the potential to stabilize noble metal nanoparticles due to the positive charge of PEI. In this study, we synthesized the amphiphilic PEI-oleic acid molecule by acylation reaction. Amphiphilic PEI-oleic acid assembled into stable PEI-oleic acid micelles with a hydrodynamic diameter of about 196 nm and a zeta potential of about 34 mV. The PEI-oleic acid micelles-stabilized palladium nanoparticles (PO-PdNPsn) were prepared by the reduction of sodium tetrachloropalladate using NaBH4 and the palladium nanoparticles (PdNPs) were anchored in the hydrophilic layer of the micelles. The prepared PO-PdNPsn had a small size for PdNPs and good stability in solution. Noteworthily, PO-PdNPs150 had the highest catalytic activity in reducing 4-nitrophenol (4-NP) (Knor = 18.53 s−1mM−1) and oxidizing morin (Knor = 143.57 s−1M−1) in aqueous solution than other previous catalysts. The enhanced property was attributed to the improving the stability of PdNPs by PEI-oleic acid micelles. The method described in this report has great potential to prepare many kinds of stable noble metal nanoparticles for treating aqueous pollution.

The aim of the work is to search for new drugs and technologies for processing textile materials to achieve high quality products with minimum costs and practical absence of harmful industrial emissions. Studies on the use of insoluble aluminum silicate in practical application in the textile industryare conducted at the Ivanovo State University of Chemical Technology. The experience of using silicates for modifying the properties of wool fibre and purification of exhaust dyeing solutions from direct, active and acidic dyes has been accumulated. The article considers the possibility of using fluorinated aluminum silicate (xAl2O3 * ySiO2 * zAlF3), which is a by-product in manufacture of aluminum fluoride, when coloring textile materials with pigment dyes. The uniqueness of this preparation lies in the fact that fluorinated aluminum silicate combines two fractions: insoluble (silicon and aluminum oxides) and soluble (aluminum fluoride). Aluminum fluoride has a limited solubility in water (0.41% by weight at 25 ° C), but is catalytically active and is used in a number of chemical processes as a catalyst. Due to the presence of water-soluble aluminum fluoride, fluorinated aluminum silicate has an acidic reaction. This powder is finely dispersed and its insoluble part has a white color, so it can be used as filler for blending printing inks and a catalyst for the dye fixing process on the fibre. The color and strength characteristics of the obtained stains convincingly prove that the fluorinated aluminum silicate can successfully replace commercially available catalysts. An additional positive feature is an increase in the shelf life of the finished printed composition. The limited solubility of aluminum fluoride, on the one hand, and its distribution in the structure of insoluble alumina and silicon oxides, on the other, makes the preparation catalytically inactive at room temperature, which positively affects the stability of the ink. Another option for the use of fluorinated aluminum silicate in combination with pigments can be purification of exhaust dyeing solutions. In this case, the high sorption activity of fluorinated aluminum silicate with respect to pigments plays a leading role. If fine dispersed fluorinated aluminum silicate is placed in the aqueous dispersion of the pigment, then, settling, it will capture the dye. Within 24 hours, the dispersion completely discolored. At the same time, the settled powder acquires a pigment tint. The results of the research presented in this paper make it possible to talk about the technological possibilities of using fluorinated aluminum silicate in the coloring of textile materials with pigments in which both its sorption ability and catalytic activity are in demand.

Cultural Message

The bread in one form or another has been known to people all over the world. Linguistic data and rites show that the Lithuanians have been eating bread since ancient times. Bread is mentioned in the small-form verbal folklore, songs, sagas, fairy tales, beliefs and various rites. In ancient times the bread was personalised and deified. The examples from the dialect dictionaries were also included into the research because every dialectal saying is an example of cultural message, manifestation of tradition nurturance and preservation, a part of cultural heritage, which links the past with the present. The dialectal examples show, what is deep-rooted in the tradition, what is passed down from generation to generation, what lies in the traditional value system and what makes the essence of an ethnic group. Due to these reasons the dialectal texts have a huge public or cultural value as they denote a content that is significant to a certain community. Having completed the analysis of dialectal discourse, it can be stated that various dictionaries construct the following picture of the concept bread: bread is the main meal of people, it is baked from different kinds of cereal flours, it is respected and saved, it has healing powers; the bread baked at home is the most delicious; if there is no bread, a person starves; to have bread all the time one has to work hard because baking bread is labour-intensive work, which has to be performed with knowledge and love, to make bread delicious and fragrant, calamus, cabbage or maple leaves are put under a loaf of bread, it is decorated or marked with sacred signs; an individual equals bread with human activity and appearance; bread is a measure of life, a reference point for evaluating certain actions. The place of bread in the human life is reflected by derivates as well: special things, capacities for mixing, souring, baking, slicing or keeping bread; other meals prepared from bread.

Different beliefs and practices are found in human life from birth to death. These beliefs are created by the people and are followed and protected by the mother’s community. Man has been living with nature since ancient times. Beliefs appeared in natural human life. Hope can be traced back to ancient Tamils and still prevails in Tamil Nadu today. The hope of seeing the omen in it is found all over the world. Proverbs show that people have faith in omens. Our ancestors wrote the book 'Gauli Shastri' because the lizard omen is very important in our society. The word lizard played a major role in Tamil life during the Sangam period. It is possible to know that people have lived by the benefit of the lizard. There is hope from the public that the sound of the lizard will predict what will happen next. The purpose of this article is to illustrate the lizard word that has been around for a long time in folklore.

Christian History

The article deals with one of the most popular techniques in Belarusian magical medicine — the so-called historiolae, the essence of which is to recall precedent situations. This implies that the “disequilibrium of being, which has arisen in human life at the present moment (e.g. a disease), is restored according to a sacred pattern that took place in the past”. The texts declare connections between different levels of the worlds, past and present, but to the same extent between the microcosm and the macrocosm, erasing all distinctions between the real and the supernatural worlds. The present time of these charms prevents the transfer of the patient and the healer to ancient times of the myths. Instead, it is the sacred world that spreads around the requester. The most common form of such charms includes a narrative that relates certain events in Christian history, primarily describing the life of Christ or of one of the saints. A particular place among the narrative manifestations of historiolae is occupied by references to the Passion of Christ. These narratives, in turn, possess powerful life-affirming and healing potential. It is not the logical correspondence of a specific comparison in an incantation that is central, but the very desire to place the situation of treatment in an appropriate context. A number of texts from the author’s field records and archival materials are introduced here into scholarly circulation.
