Aggregation‐Controlled Vat Dyeing of Meta‐Aramid Fibers: Mechanistic Insights and Suppression of Surface Dye Deposition

Advanced Materials Interfaces, EarlyView.
Supramolecular aggregation governs the interfacial adsorption, diffusion, and fixation of anthraquinone‐based vat dyes in meta‐aramid fibers. By correlating reduction chemistry, aggregate formation, and fiber microstructure, a multiscale mechanism for aggregation‐controlled dyeing is established, providing an effective strategy to suppress surface dye ...

Do Xylem Fibers Affect Vessel Cavitation Resistance? [PDF]

Plant Physiology, 2005
Abstract Possible mechanical and hydraulic costs to increased cavitation resistance were examined among six co-occurring species of chaparral shrubs in southern California. We measured cavitation resistance (xylem pressure at 50% loss of hydraulic conductivity), seasonal low pressure potential (P  min), xylem conductive efficiency ...
