Coral bleaching events are often associated with higher levels of coral mortality but when this occurs in the chronology of individual bleaching events is poorly documented. Knowing when mortality occurs is important for understanding molecular mechanisms and the putative adaptive significance of the response (the Adaptive Bleaching Hypothesis).

Pulp Bleaching and Bleaching Effluents
2013In Kraft pulping, about 90–95 % of wood lignin gets solubilized during the cooking process. The remaining 5–10 % of lignin is responsible for the brown color of the Kraft pulp and unbleached paper. The objective of bleaching is to remove the residual lignin from the pulp as selectively as possible, without degrading the pulp carbohydrate, especially ...

Bleaching Activators and the mechanism of bleaching activation
Journal f�r Praktische Chemie/Chemiker-Zeitung, 1992Bleaching activators are compounds with O- or N-bounded acetyl groups which are able to react with the strongly nucleophilic hydroperoxy anion to yield peroxyacetic acid. The peroxyacetic acid is decomposed in weakly basic media in a bimolecular reaction forming singlet oxygen.

Selection of bleaching agents for dry bleaches
Journal of the American Oil Chemists' Society, 1983AbstractDry bleaches or all‐fabric dry bleaches are increasing in usage (7% +, annually, is quoted) because the consumer is seeking fabric and dye safety coupled with good stain removal. Additionally, the consumer wants a product which requires less sorting of fabrics or colors and aids in the cleansing and stain‐removal action without color, fabric ...
