Study of enantioseparation of β-blockers using amylose tris(3-chloro-5-methylphenylcarbamate) as chiral stationary phase under polar-organic, reversed-phase and hydrophilic interaction liquid chromatography conditions
(Elsevier, 2020-12)
In this study, we describe the experimental variables influencing enantioseparation of twelve β-blockers when analyzed under polar-organic, reversed-phase and hydrophilic interaction liquid chromatography conditions on a ...
Phase Characterization of Lead Zirconate Titanate Obtained from Organic Solutions of Citrates
(1992-01-01)
Lead zirconate titanate (PZT) with several Zr/Ti ratios was prepared by the organic solution of citrates of the respective cations. The Rietveld method was applied to perform quantitative analysis of the coexisting phases. ...
Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...

Advances in metal-mediated solid-phase synthesis of heterocyclic compounds
(Springer, 2017)
While heterocycles are a key feature frequently found in compounds with pharmaceutical or agrochemical interest, the combination between solidsupported synthesis and organometallic chemistry has demonstrated to be a helpful ...
Reevaluation of ethanol as organic modifier for use in HPLC-RP mobile phases
(Soc Brasileira QuimicaSao PauloBrasil, 2004)
Desenvolvimento longitudinal do andar para frente e para trás: Impacto da restrição ambiental
(2006-12-01)
The purpose of this study was to investigate, through longitudinal observations, the onset and development of forward and backward walking in their temporal organization and the impact of environmental constraints. The ...
