A new class of zirconia supported mixed metal oxides (ZnO-TiO(2)-Nd(2)O(3)/ZrO(2) and ZnO-SiO(2)-Yb(2)O(3)/ZrO(2)) has demonstrated the ability to convert low quality, high free fatty acid (FFA) bio-oils into biodiesel. Pelletized catalysts of ZrO(2) supported metal oxides were prepared via a sol-gel process and tested in continuous flow packed bed reactors for up to 6 months. In a single pass,...
An N-acetylgalactosaminyltransferase, which converts blood group 0 red blood cells to A cells, was purified to homogeneity from plasma of blood group A, subjects. The enzyme was adsorbed on Sepharose QB, and after washing out the impurities, the enzyme was eluted with UDP. This procedure resulted in a 70,000to lOO,OOO-fold increase in specific activity with recovery of about 80%. Further purifi...
Nanoporous poly(2-hydroxyethyl methacrylate-co-ethylene dimethacrylate) (HEMA-EDMA) is used as a 3D mesh for spotting lipid arrays. Its porous structure is an ideal matrix for lipid ink to infiltrate, resulting in higher fluorescent signal intensity as compared to similar arrays on strictly 2D substrates like glass. The embedded lipid arrays show high stability against washing steps, while stil...
This study was an attempt to produce bio-oil from empty fruit bunches (EFB) of oil palm waste using fast pyrolysis technology. A 150 g/h fluidised bed bench scale fast pyrolysis unit operating at atmospheric pressure was used to obtain the pyrolysis liquid. A comparison of the elemental composition of unwashed and washed feedstock was made in this study. With the five methods of treatment being...
