Abstract A chemical modification of cotton fabrics by 2-diethylaminoethyl chloride (DEAE-Cl) was achieved, and the resulted demonstrated salt-free dyeing properties with anionic dyes. Nucleophilic property hydroxyl groups in cellulose enhanced under alkaline conditions could react DEAE-Cl, a possessing both nucleophilic electrophilic sites. The monolayered DEAE-grafted further DEAE-Cl to form m...

A complete study of thermophysical properties concerning the 2-(2-diethylaminoethoxy)ethanol (DEAE-EO) + water binary system is realized. Density, speed sound, dynamic and kinematic viscosities refractive index measurements have been performed at atmospheric pressure, using a vibrating tube densitometer, falling ball viscosimeter, refractometer for pure DEAE-EO, water, aqueous solutions from 27...

introduction : albumin, one of the most important plasma proteins, has a difficult process of synthesis and production. we compared two different methods for albumin purification: carboxymethyl cellulose (cm cellulose) resin exchange and diethylaminoethyl cellulose (deae cellulose) resin exchange in order to determine which resin could be more beneficial. materials and methods : two ion exchang...

Document-level event argument extraction (DEAE) aims to identify the arguments corresponding roles of a given type in document. However, scattering and overlapping make DEAE face great challenges. In this paper, we propose novel model called Role Knowledge Prompting for Document-Level Event Argument Extraction (RKDE), which enhances interaction between templates through role knowledge guidance ...

We evaluated a more practical and cost-effective immobilization carriers for ethanol production using the yeast Saccharomyces cerevisiae. Three candidate materials-rice hull, rice straw, and sawdust-were tested for their cell-adsorption capacity and operational durability. Derivatizations of rice hull, rice straw, and sawdust with the optimal concentration of 0.5 M of 2-(diethylamino)ethyl chlo...
