Abstract:
Color is the prime feature directly associated with the consumer’s attraction and choice of their food. The flavor, safety, and nutritional value of any food product are directly associated with the food color. Natural and synthetic colorants (dyes and pigments) have diversified applications in various sectors such as food, feed, pharmaceutical, textiles, cosmetics, and others. Concerning the food industry, different types of natural and synthetic colorants are available in the market. Synthetic food colorants have gained popularity as they are highly stable and cheaply available. Consumers wo

Abstract:
As a part of an ongoing interest in identifying environmentally friendly alternatives to synthetic dyes and in using liquid CO2 as a waterless medium for applying the resulting colorants to textiles, our attention turned to yellow-to-red biocolorants produced by Cortinarius sanguineus fungus. The three principal target anthraquinone colorants (emodin, dermocybin, and dermorubin) were isolated from the fungal bodies using a liquid–liquid separation method and characterized using 700 MHz NMR and high-resolution mass spectral analyses. Following structure confirmations, the three colorants were e

Abstract:
Dyes (colorants) are used in many industrial applications, and effluents of several industries contain toxic dyes. Dyes exhibit toxicity to humans, aquatic organisms, and the environment. Therefore, dyes containing wastewater must be properly treated before discharging to the surrounding water bodies. Among several water treatment technologies, adsorption is the most preferred technique to sequester dyes from water bodies. Many studies have reported the removal of dyes from wastewater using biochar produced from different biomass, e.g., algae and plant biomass, forest, and domestic residues, a

Abstract:
Use of dyes as well as colorants in industrial processes has extensively increased. Effluents from various industries such as textile, paint, food, etc. are reported to have a diverse range of colorants. The effluents from these industries are often released into natural water bodies, causing serious water and environmental pollution, to which humans and other species are constantly exposed. Continued changes in climate have also affected water availability for people around the world. Thus, advanced treatments and removal of harmful contaminants from municipal and industrial wastewater are be

ABSTRACT The last stage of activity of the Ischigualasto–Villa Unión Rift Basin in west-central Argentina is represented by the 1100-m-thick fluvial red-beds of the Los Colorados Formation (Norian). Facies and architectural-element analysis were applied and vertical stacking patterns evaluated in the Los Colorados Formation to develop a depositional model for the postrift stage of basin fill. The Los Colorados Formation is subdivided into eleven stratigraphic intervals, generally characterized by multistory and multilateral channelized bodies interspersed with thick floodplain deposits develop

Abstract:
Terracotta is valuable for its mineral content, which produces pigments for coloring ceramic bodies and glazes. Unlike commercial colors, terracotta's natural minerals make it unique. This study explores the potential use of local terracotta clay in transparent glaze formulations. Methods like clay powder percentages, X-ray diffraction, X-ray fluorescence tests, electron scanning, and microscope analysis (SEM) are used to examine the clay elements' morphology and structure. The addition of terracotta clay powder in proportions (20-50%) rendered the glaze translucent. Samples were applied on po

Abstract:
Colour is an important factor to enhance the consumer acceptance and appetizing value towards food and beverages. Foods are coloured with both natural and artificial/ synthetic food dyes. Instead of natural food colours, synthetic food colours are now widely employed by the food industry because of its superior features (cheap cost, enhanced look, greater colour intensity, increased colour stability, and consistency). Life of synthetic colorants is quite long as they are highly soluble in water and oil. Based on their solubility, synthetic colorants are classified into fat soluble synthetic co

Abstract : The transfer of energy between excited state chromophores is a topic of interest in the area of natural and laboratory photonic devices. Indeed, energy transfer is a process seen in nature in all photosynthetic organisms from complex multicellular plants to simple, single cell photosynthetic bacteria. For example, the purple photosynthetic bacteria uses two protein assemblies, referred to as the light-harvesting protein 1 (LH1) and the light-harvesting protein 2 (LH2), to collect light energy in order to survive. The LH2 protein serves only to absorb and transmit light energy to the

Urbanization and industrialization contribute to anthropogenic pollution, which harms ecological stability and climate change. Pollutants enter water bodies through a variety of point and non-point sources, with wastewater discharge being a major one. The existing conventional wastewater treatment methods are costly; therefore, a sustainable alternative approach to treatment costs must be obtained.
