Synthesis of YAP phase by a polymeric method and phase progression mechanisms
The phase formation kinetics of YAP (YAlO(3)) synthesized through the polymeric precursor method was investigated by thermal analysis, X-ray diffraction and FT-IR spectroscopy. We demonstrated that the YAP synthesis is ...
Structure and Properties of Barium Bismuth Titanate Prepared by Mechanochemical Synthesis
(Taylor & Francis Ltd, 2008-01-01)
Bi4Ti4O15 [BBT], a member of Aurivillius bismuth-based layer-structure perovskites, was prepared from stoichiometric amounts of BaTiO3 [BT] and Bi4Ti3O12 [BIT] obtained via mechanochemical synthesis. Mechanochemical synthesis ...
A Sequential Integration between Optimal Flexible Heat Exchanger Network Synthesis and Control Structure Design
(American Chemical Society, 2018-08)
In this work, the optimal synthesis and control structure design (CSD) problems for flexible heat exchanger networks (HENs) are integrated into a new sequential methodology. The proposed approach relies, on one hand, on a ...
Poly(3-hydroxybutyrate) synthesis by recombinant Escherichia coli arcA mutants in microaerobiosis
(American Society for Microbiology, 2006-04)
We assessed the effects of different arcA mutations on poly(3- hydroxybutyrate) (PHB) synthesis in recombinant Escherichia coli strains carrying the pha synthesis genes from Azotobacter sp. strain FA8. The arcA mutations ...
Optimal Feedback Synthesis and Minimal Time Function for the Bioremediation of Water Resources with Two Patches
This paper studies the bioremediation, in minimal time, of a water resource or reservoir using a single continuous bioreactor. The bioreactor is connected to two pumps, at different locations in the reservoir, that pump ...
Isolation, synthesis and bioactivity studies of phomactin terpenoids
(Nature Publishing Group, 2018-09-01)
Studies of secondary metabolites (natural products) that cover their isolation, chemical synthesis and bioactivity investigation present myriad opportunities for discovery. For example, the isolation of novel secondary ...
Triglyceride synthesis by human bone marrow fibroblasts
An increase in triglyceride synthesis has been observed in cultures of human bone marrow fibroblasts after the cells reach confluence. The addition of hydrocortisone further enhances triglyceride synthesis. Conditioned ...
Dualistic Nature of the Mechanism of the Morita-Baylis-Hillman Reaction Probed by Electrospray Ionization Mass Spectrometry
(Amer Chemical SocWashingtonEUA, 2009)
Buthionine sulfoximine has anti-Trypanosoma cruzi activity in a murine model of acute Chagas' disease and enhances the efficacy of nifurtimox
(AMER SOC MICROBIOLOGY, 2008)
L-Buthionine (S,R)-sulfoximine (BSO) at a dose of 220 mg/kg of body weight/day showed an anti-Trypanosoma cruzi effect in infected mice, increasing their survival rate and decreasing the parasitemias and parasite burden ...
