The molecular deformation of cotton cellulose whisker/epoxy resin (CW/EP) and tunicate whisker/poly(vinyl) acetate (TW/PVAc) composites were investigated using Raman spectroscopy. A shift in the 1095 cm Raman peak position is recorded for samples deformed in both tension and compression, which corresponds to the molecular deformation of the cellulose chains within the whiskers. Cyclic molecular...
Haematological and biochemical aspects of a new family with heterozygous Hb O Padova [alpha 30(B11) Glu----Lys] is described. This variant has been found on a screening programme of abnormal haemoglobin in cord blood. It was separated by cellulose acetate, isoelectric focusing, citrate agar, DEAE-cellulose chromatography and by cation exchange high-performance liquid chromatography. The heat st...
