Production of Oleic Acid Based Wax Ester Using Acidic Homogeneous Catalysts

open access: yesJournal of Chemistry, Volume 9, Issue 1, Page 99-106, 2012., 2012
Four homogeneous acidic catalysts were tested for their ability to catalyze the esterification reaction of oleic acid and oleyl alcohol to produce oleyl oleate, a wax ester. Sulfuric acid showed relatively higher specific activity. Various reaction parameters were optimised to obtain high percentage yield of oleyl oleate.

Breast Carcinoma, Intratumour Heterogeneity and Histological Grading, Using Geostatistics

open access: yesAnalytical Cellular Pathology, Volume 20, Issue 2-3, Page 83-91, 2000., 2000
Tumour progression is currently believed to result from genetic instability. Chromosomal patterns specific of a type of cancer are frequent even though phenotypic spatial heterogeneity is omnipresent. The latter is the usual cause of histological grading imprecision, a well documented problem, without any fully satisfactory solution up to now.
