Optoelectronic Properties of Natural Cyanin Dyes

The Journal of Physical Chemistry A, 2009
An integrated theoretical/experimental study of the natural cyanin dye is presented in terms of its structural and optoelectronic properties for different gas-phase and prototypical device configurations. Our microscopic analysis reveals the impact of hydration and hydroxylation reactions, as well as of the attached sugar, on ground and optically ...

Natural dye senstizers for photoelectrochemical cells

Energy & Environmental Science, 2009
In nature, fruit, vegetable, leaves, flowers and algae contain several dyes which can be easily extracted and employed in dye sensitized photoelectrochemical cells. In this contribution, the most significant advances made in the search for efficient and convenient natural sensitizers are reported through meaningful examples and case studies.

Sustainable Dyeing of Silk with Natural Dyes Using Natural Sources of Water

Journal of The Institution of Engineers (India): Series E, 2020
River water containing different types of metals and heavy metals are far more efficient in promoting surface colour strength and all round colourfastness properties of silk fabrics when dyed with aqueous extract of Ceriops decandra and Diospyros malabarica. However, pre-mordanting with aluminium and/or ferrous sulphate would promote the depth of shade

Sustainable Dyeing of Wool by Natural Dyes in Conjunction with Natural Mordants

2021
Indians are known as precursors in natural dyeing art. Even though home-grown knowledge mode has been experienced in the past over the years but applications of natural colourants have been reduced due to lack of methodical knowledge of extraction, dyeing procedures and documentation over generations.

Unconventional Natural Dyeing Using Microwave Heating with Cochineal as Natural Dyes

Research Journal of Textile and Apparel, 2011
This research concerns making wool fabrics with dye extracted from cochineal using microwave heating. The result shows good fastness properties. To promote value addition in domestic processing and to boost rural income and employment in small-scale agroenterprises, it is necessary to promote non-polluting natural dyes, which involve inexpensive ...
