“…While alcoholic or acidic carmine preparations may be stable, alkaline preparations encourage autolysis and fermentation of macerated cochineal insects . This could be involved in the two cochinilla dyes described here but, in addition, there is no guarantee that these locally sourced dyes do not contain other colorants, either synthetic or from Amazonian plants, such as annatto from Bixa orellana . Colorants from Dactylopius species are predominant, both for histology and traditional Andean textiles, but the situation for the history of textiles is more complicated because several genera of European scale insects also produce red anthraquinone dyes .…”

Spectra were strongly influenced by the way they were measured but, in general, carmine, cochinilla rojo and rosada, and red annatto all had strong transmittance and reflectance of red light (>640 nm), and strong absorbance of green light (520-560 nm). Spectra for carmine and cochinilla rosada both had secondary peaks for transmittance and reflectance (around 420 and 450 nm for stains, respectively), whereas secondary peaks were not found for cochinilla rojo and red annatto. Both cochinilla rosada and rojo stained skeletal myofibers, but only cochinilla rojo withstood alcohol dehydration and mounting as a general stain for paraffin sections. Carmine was ideal for enhancing the appearance of pork because its spectrum was similar to that of myoglobin, thus increasing the absorbance of green light without producing unnatural colors like cochinilla rosada and rojo. Cochinilla rojo dyed alpaca wool orange, and cochinilla rosada dyed wool pink. The scale of the measurement (micro-vs. macroscopic) and the type of measurement (transmittance vs. reflectance) were of minor importance in colorimetry, whereas a major effect was detected for light scattering in the sample. A ratio indicative of scattering (400/700 nm) was strongly correlated with chromaticity coordinate x, r 5 20.86, P < 0.001, n 5 18.

Summary An innovative dye‐sensitized solar cell based on achiote seeds with a new dual electrical generation mechanism is presented. This dye‐sensitized solar cell, in addition to the well‐known mechanism, where the conduction electrons are released from the dye molecules due to their interaction with photons, shows a distinct chemical mechanism that produces an effective electric current under dark conditions. Both mechanisms operate simultaneously; however, the electrical signal obtained from the photoelectrical mechanism is stronger. Additionally, during a rapid transition from darkness to illuminate conditions, non‐linear oscillations in the current signal are produced when the system is shifted rapidly far from equilibrium conditions.

“…https://www.indjst.org/ Nowadays, the use of natural dyes for leather has been increasing. Several previous studies have investigated the use of some natural dyes on leather, such as Bixa orellana seed extracts (2) , Henna leaf extracts (Lawsonia inermis) (3) , and Marigold flower extracts (Tagetes erecta L.)

Background/Objectives: The eco-printing method is a dye transfer process that produces natural shapes of leaves and flowers on sheep leather. The research objective aimed at determining the quality of sheep crust leather using the eco-printing method. Methods/Statistical analysis: The research applied the experimental method using sixteen sheets of sheep crust leather. The study employed a completely randomized design. The treatments involved soaking the crust leather in a mordant of alum solution with several soaking times, namely (T0) = 0 hours, (T1) = 12 hours, (T2) = 24 hours, and (T3) = 36 hours; each of the treatments was repeated four times. The research variables included wet rubbing resistance, sweat resistance, washing resistance, tear strength, elongation, and seam strength. The data were analyzed using anova. Findings: The results showed that the soaking time did not significantly affect (P> 0.05) on tear strength, elongation, and seam strength. However, it had a significant effect (p <0.05) on wet rubbing resistance, sweat resistance, and washing resistance. Therefore, the crust leather soaked in the mordant of Aluminum potassium sulfate for 36 hours before being dyed using the ecoprinting method did not show any decrease in its physical quality. It even showed some improvements of wet rubbing resistance with the value of 4 and 5, sweat resistance with the value of 4, and washing resistance with 4 to 5. Novelty/Applications: Natural dyeing using the eco-printing method can be applied to sheep crust leather to improve the quality of wet rubbing resistance, sweat resistance, and washing resistance. It is also recommended that crust leather be soaked in Aluminum potassium Sulfate's mordant solution for 36 hours.
