Hemicellulose lean pulps are a raw material source for numerous high value products. We have previously presented the IONCELL-P(ulp) process, a hemicellulose extraction method, based on a binary mixture of ionic liquid and water. The IONCELL-P proces

High purity cellulose from wood is an important raw material for many applications such as cellulosic fibers, films or the manufacture of various cellulose acetate products. Hitherto, multi-step refining processes are needed for an efficient hemicell

In our recent studies, it was demonstrated that the IONCELL-P process selectively dissolves hemicelluloses from bleached birch kraft pulp in a mixture of 1-ethyl-3-methylimidazolium acetate ([emim][OAc]) and water as a solvent system. The IONCELL-P m

Alterations at chromosome locus 4q12 are frequently found in gliomas; this locus contains the receptor tyrosine kinase–encoding genes KIT , PDGFRA , and KDR (alias VEGFR2 ). Notable among the genes at this locus is LNX1 , the ligand of Numb protein
