The textile industry contributes significantly to environmental pollution through massive water usage and toxic synthetic dye effluents. Bioremediation offers a sustainable solution by using microorganisms, such as bacteria, to transform complex cont...
Natural food pigments such as curcumin and β-carotene are valued for their coloring properties and health-promoting bioactivities, including antioxidant and anticancer effects. However, both compounds are susceptible to light-induced degradation...
Fungi in the Chlorociboria genus produce a blue pigment called xylindein—a pigment with high UV stability, photovoltaic capacity, and which is used as a historic wood colorant. The pigment has not yet been synthesized; however, recent studies h...
This paper reports the controlled synthesis of ZrO2 nanocrystals via a peroxide-assisted hydrothermal (HT) route at 120 °C, with processing times ranging from 12 to 72 h, and investigates the correlation between structural evolution, defect chemi...
Hydroxygallium phthalocyanine type V (HOGaPc V) is an excellent photo generator and is applied in xerography. The material is only accessible as polycrystalline substances, and the crystal structure for an evaluation of the structure–property r...
This study examines the colorimetric characteristics and possible biological effects of the quinoline-derived dye M1 1,4-bis((E)-2-(quinolin-2-yl)vinyl)benzene. The pi-conjugated structure and high planarity of M1 give it important semiconductor and...
Melanin is a biological pigment known for its broadband UV-Vis absorption and structural disorder, which collectively determine its chromatic response. In this study, melanin–silica hybrid materials were synthesized via sol–gel processing...
In recent years, increasing consumer demand for healthier and more natural foods has driven the food industry to replace artificial additives. Among these, colorants play a crucial role, as they influence the sensory perception and acceptance of food...
We report a π-extended N-phenylphenothiazine dye bearing thiophene substituents, designed to address the practical compromise between long-wavelength near-infrared (NIR) absorption and the isolability of a stable radical cation state. The target c...
The development of bio-based inks represents a promising strategy to reduce the environmental impact of digital printing technologies. This study investigates the formulation and performance of water-based inks incorporating two renewable pigments: a...
By examining historical recipes from the medieval treatise The Montpellier Liber Diversarum Arcium, the creation of bottle green and verdigris pigments involved various types of tempera, such as parchment glue and gum arabic. Malachite was also prepa...
Water contamination by synthetic dyes such as malachite green (MG) remains a significant environmental and public health challenge due to their high toxicity, chemical stability, and resistance to biodegradation. In this study, a CaO-CuFe2O4 composit...
Light-based diagnostic and therapeutic approaches are increasingly important in modern biomedicine, with organic dyes emerging as versatile optical agents due to their tunable photophysical properties. Precise control over absorption and emission cha...
