Separation of human immunoglobulin G subclasses using monolithic column
Leblebici, P.; Rodrigues, A.E.; Pais, L.S.The present study aims to separate hIgG into its subclasses using monolithic stationary phase.
Multicomponent chiral separations by multicolumn and simulated moving bed adsor...
Ribeiro, António E.; Graça, Nuno S.; Ferreira, Alexandre P.; Rodrigues, A.E.; Pais, L.S.This work will present a complete methodology concerning experimental, modelling and simulation results. Both the CHIRALPAK AD and CHIRALPAK IA CSP will be evaluated. The selection of the proper CSP/solvent combination for preparative operation will be fully study taking into account the screening strategy proposed by Zhang et al. Additional results include the measurement of nadolol stereoisomers solubilities,...
Monolith technology in isolation of human immunoglobulin G subclasses
Leblebici, P.; Rodrigues, A.E.; Pais, L.S.In the present study, a method was developed for the separation of hIgG into its subclasses with the advantages of monolithic technology. pH elution was applied using Protein A monolith column in a stepwise method and conditions were optimized. Since IgG3 has very low affinity to Protein A, elution was occurred immediately upon injection of the sample. IgG1 and IgG4 were eluted simultaneously under the applied ...

Comprehensive insights into lignin oxypropylation reaction
Cateto, C.A.; Barreiro, M.F.; Rodrigues, A.E.; Belgacem, N.Polyols resulting from oxypropylation are a mixture of oxypropylated lignin and some low molecular weight products (polypropylene oxide oligomers). Normally these oligomers are left in the final mixture since they constitute useful co-monomers, lowering the Tg and the viscosity of the resulting liquefied lignin. In this work a series of polyols based on Alcell lignin have been produced using L/PO ratios (Lignin...
Hexane isomers sorption on the rigid framework MOF MIL-100(Cr)
Mendes, Patricia; Silva, José A.C.; Rodrigues, A.E.In this work we studied the hexane isomers sorption on the MIL-100(Cr) [1]. The first part of the study was related to the pattern MIL-100(Cr) solid, the second dealt with the MIL-100(Cr) grafted with EtAp (Ethylamine pure) and the third with MIL-100(Cr)MEDA (Methyl ethylene diamine). The synthesis and characterization of MIL-100 (Cr), MIL-100(Cr)EtAp and MIL-100(Cr)MEDA was performed at Institut Lavoisier de V...
Porous solids for biogas upgrading
Silva, José A.C.; Rodrigues, A.E.In this work, we will present sorption equilibrium, kinetic and fixed bed data of CO2, CH4 in MOF-508b and zeolite 13X at 303, 323 and 343 K and partial pressures up to 4.5 bar. These data are fitted with appropriate isotherm models. At the same time single, binary and ternary breakthrough curves were measured to provide required data to develop and validate a mathematical model based on the LDF approximation f...

Multicomponent hexane isomers sorption on MOF ZIF-8
Mendes, Patricia; Silva, José A.C.; Rodrigues, A.E.; Horacajada, Patricia; Serre, ChristianThe main goal of this research focuses on the development of an adsorptive process to separate hexane isomers (kinetic diameter very similar) in order to improve the quality of gasoline measured by the octane number (RON). In this investigation, studies of sorption equilibrium of hexane isomers: n-hexane (RON 25), 3-methylpentane (RON 75), 2,3-dimethylbutane (RON 103) and 2,2-dimethylbutane (RON 94) were perfor...
