Evaluation of ion exchange material from sulfonated polystyrene waste synthesized for removal Cr3+ from aqueous solution by column experiment

The paper aims to study the effect of operatiing conditions in the column experiment with the ion exchange material which was prepared in optimum synthesized conditions. Polystyrene waste from disposable food packaging was dissolved in cyclohexane and sulfonated by sulfuric acid to synthesize cation exchange materials which were applied to remove Cr3+ in water by the ion exchange principle.

Báo cáo Y học: Chemical structures and immunolocalization of glycosphingolipids isolated from Diphyllobothrium hottai adult worms and plerocercoids

Glycosphingolipids (GSLs) were puriﬁed from adults and plerocercoids of the tapeworm Diphyllobothrium hottai, and their chemical structures were determined. Total lipid fractions prepared from chloroform/methanol extracts of whole tissues were fractionated successively on ion-exchange chromatography, silicic acid column chromatography, and preparative TLC. The puriﬁed GSLs were characterized by methylation analysis, TLC-immunostaining, liquid secondary ion MS, MALDI-TOF MS, and 1H-NMR.

Báo cáo khoa học: Protein oligomerization induced by oleic acid at the solid–liquid interface – equine lysozyme cytotoxic complexes

Protein oligomeric complexes have emerged as a major target of current research because of their key role in aggregation processes in living systems andin vitro. Hydrophobic and charged surfaces may favour the self-assembly process by recruiting proteins and modifying their interactions. We found that equine lysozyme assembles into multimeric complexes with oleic acid (ELOA) at the solid–liquid interface within an ion-exchange chromatography column preconditioned with oleic acid.
