Optimization of a Green Dyeing Process Using Natural Dyes Extracted from Corchorus Olitorius Leaves

Journal of Natural Fibers, 2023
The main purpose of this study is to develop a green dyeing process using Corchorus olitorius dye extract. Corchorus olitorius leaves were used as a new dyestuff source that has never been used for cotton fabric dyeing. Dye extraction was performed using

Angular Momentum Mixing in Crystalline Color Superconductivity [PDF]

, 2002
In crystalline color superconductivity, quark pairs form at non-zero total momentum. This crystalline order potentially enlarges the domain of color superconductivity in cold dense quark matter.

Eco-Friendly Dyeing of Pretreated Cotton Fabric Using a Natural Dye Extract from Erythrina abyssinica

Journal of Natural Fibers, 2022
The increasing awareness of toxicity of synthetic dyes has considerably raised the demand for natural dyes. Retaining color fastness and strength of natural dyes on fabric is the main limitation in textile dyeing with natural dyes.

Influence of coloring liquid immersion on flexural strength, Vickers hardness, and color of zirconia

The Journal of Prosthetic Dentistry, 2021
Zirconia is a widely used restorative material, yet its white color does not meet esthetic requirements and coloring is needed. However, the effects of different durations of coloring have not been thoroughly investigated.The purpose of this in vitro study was to evaluate the effects of coloring liquid immersion of different durations on the flexural ...

Optimized Dyeing of Cotton with semi-synthetic Embelin Ninhydrin Dye Obtained by Chemical Modification of Embelin from Embelia Schimperi

Journal of Natural Fibers, 2022
Chemical modification is a promising path to address the limitations of a natural dye, such as limited shades and inadequate fastness properties. This study investigated the modification of embelin (2, 5-dihydroxy-3-undecyl-1, 4-benzoquinone) a plant ...

Electron Population Aging Models for Wide-Angle Tails [PDF]

, 1999
Color-color diagrams have been useful in studying the spectral shapes in radio galaxies. At the workshop we presented color-color diagrams for two wide-angle tails, 1231+674 and 1433+553, and found that the standard aging models do not adequately ...
