Supramolecular Modulation of Photoinduced Charge Transfer: Tuning Between Tunneling and Incoherent Hopping

Angewandte Chemie, EarlyView.
Molecular recognition guest binding can comprehensively modulate photoinduced charge‐transfer dynamics in the cyclophane host, including charge separation and recombination, via coherent superexchange and incoherent hopping. Unlike covalent donor–bridge–acceptor systems, this supramolecular approach avoids tedious syntheses and offers precise tuning of

Extraction and optimisation of red pigment production as secondary metabolites from Talaromyces verruculosus and its potential use in textile industries

Mycology, 2017
Textile dyes and effluents are considered as one of the worst polluters of our priceless water sources and soils. New sources of natural pigments are getting particular research interests due to the toxicity produced by synthetic colouring agents.

Printing with Sustainable Natural Dyes and Pigments

, 2020
Natural dyes and pigments could be obtained from insects, plants, and animals. Natural dyes have been utilized in the dyeing of wool, cotton, and silk since the prehistoric ages. The first applications of natural dyes on textile fibers are estimated to have started in Mesopotamia and India in 4000 BC.

Guideline for High‐Performance Liquid Chromatography Detection of Anthocyanins

AgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Anthocyanins, as water‐soluble natural pigments widely present in plants, have various biological activities such as antioxidation and anti‐inflammatory, and are widely used in the fields of food, cosmetics, and medicine. However, because of the presence of unstable phenolic hydroxyl groups in their structure, they are prone to degradation due
