Neste trabalho, os nanocompósitos de interesse foram preparados, utilizando-se o Método dos Precursores Poliméricos, por meio do qual se prepararam os citratos de céria dopados com 10, 15 e 20% de gadolínio, e encapsularam-se com 3% em mol de ZrO2, em diferentes temperaturas. Para a caracterização dos materiais obtidos, utilizaram-se as técnicas de Difração de Raios X e Emissão Fotoluminescente. Verifiou-se que a alta concentração do dopante ocasiona tanto a melhoria na emissão, pela adição de defeitos, quanto a diminuição, pelo quenching da emissão.

Phase separation during the synthesis and decomposition of lead magnesium niobate (PMN)–ethylenediaminetetraacetic acid (EDTA) and PMN–citrate gels strongly affects perovskite Pb(Mg1/3Nb2/3)O3 phase formation. The PMN–EDTA gel was synthesized from a solution containing Pb–EDTA, Mg–EDTA, and peroxo–citrato–niobium complexes at pH 8. Pb–EDTA precipitation was avoided by using Pb:EDTA in the mole ratio >1:2.5 and flash pyrolyzing the PMN–EDTA solution at 225 °C. Consequently, the PMN yield increased from 80 to 98 wt%.

Abstract:
In this work, a series of supported CoMo or NiMo HDS catalysts have been prepared based on the organic-metal matrix decomposition method and tested for diesel deep HDS with minimum hydrogen consumption under relatively low hydrogen partial pressure conditions. The aim is to develop a HDS catalyst which can reduce sulphur in diesel fuel from 5000ppm down to 50 ppm in a single pass with minimum hydrogen consumption under the conditions of 340oC, 35 bar, LHSV 1.2 h-1 with low H2/oil ratio. The catalysts preparation process was monitored and the resultant catalyst samples before and after the HDS performance test have been characterised, some interesting results have been obtained. The presence of citric acid as organic additive/dispersing agent/chelating agent in the impregnation solution improved HDS activity compared to the equivalent CoMo catalyst prepared without citric acid, The order of activity of the cobalt precursors is Co citrate &gt; Co acetate &gt; Co nitrate.

Abstract:
Protein C is the precursor to a serine protease in plasma which contains gamma-carboxy glutamic acid and functions as a potent anticoagulant. Protein C shows considerable structural homology with the other vitamin K-dependent coagulation factors including prothrombin, factor VII, factor IX and factor X. This homology includes the putative pro-peptide region of the prepro leader sequences for these proteins, as well as the leader sequences for gamma-carboxylated proteins from bone. Deletion mutants have been constructed in the cDNA for human protein C in order to test the possibility that the p

Abstract:
Protein C is the precursor to a serine protease in plasma which contains gamma-carboxy glutamic acid and functions as a potent anticoagulant. Protein C shows considerable structural homology with the other vitamin K-dependent coagulation factors including prothrombin, factor VII, factor IX and factor X. Sequence analysis ofthe cDNAs for these proteins has revealedthe presence of a prepro leader sequence that contains a pre sequence or hydrophobic signal sequence and a propeptide containing a number of highly conserved amino acids. The pre region is removed from thegrowing polypeptide chain by
