Wheat-barley hybridization – the last forty years [PDF]

, 2013
Several useful alien gene transfers have been reported from related species into wheat (Triticum aestivum), but very few publications have dealt with the development of wheat/barley (Hordeum vulgare) introgression lines. An overview is given here of

Mineralization of regenerated cellulose hydrogels

Journal of Materials Science: Materials in Medicine, 2001
Due to their high water swelling, regenerated cellulose hydrogels and sponges were pre-incubated in a Ca-containing solution, and their mineralization was investigated. Results obtained demonstrate that a simple pre-incubation treatment in a Ca containing solution can induce mineralization in materials with limited or no tendency to mineralize.

Synergistic Adsorption of Heavy Metal Ions and Organic Pollutants by Supramolecular Polysaccharide Composite Materials from Cellulose, Chitosan and Crown Ether [PDF]

, 2014
We have developed a simple one-step method to synthesize novel supramolecular polysaccharide composites from cellulose (CEL), chitosan (CS) and benzo-15-crown 5 (B15C5). Butylmethylimidazolium chloride [BMIm+Cl−], an ionic liquid (IL), was used as a sole
