Surface active ionic liquids: Study of the micellar properties of 1-(1-alkyl)-3-methylimidazolium chlorides and comparison with structurally related surfactants
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
The impetus for the increasing interest in studying surface active ionic liquids (SAILs; ionic liquids with long-chain ""tails"") is the enormous potential for their applications, e.g., in nanotechnology and biomedicine. ...
Monomeric nature of dengue virus NS3 helicase and thermodynamic analysis of the interaction with single-stranded RNA
(Oxford University Press, 2014-10)
Dengue virus nonstructural protein 3 (NS3) is a multifunctional protein formed by a superfamily-2 RNA helicase linked to a protease domain. In this work, we report results from in vitro experiments designed to determine ...
Proteins as nano-carriers for bioactive compounds. The case of 7S and 11S soy globulins and folic acid complexation
(MDPI, 2018-02)
Isolated 7S and 11S globulins obtained from defeated soy flour were complexated with folic acid (FA) in order to generate nano-carriers for this important vitamin in human nutrition. Fluorescence spectroscopy and dynamic ...
Free-radical polymerization induced macrophase separation in poly(methyl methacrylate)/dimethacrylate blends: experiment and modeling
(Pergamon-elsevier Science Ltd, 2013-09-13)
This work presents the analysis of a polymerization-induced macrophase separation taking place during free-radical copolymerization of styrene and dimethacrylate in the presence of poly(methyl methacrylate) (PMMA) as a ...
Improvement of the amphiphilic properties of a dialkyl phosphate by creation of a protic ionic liquid-like surfactant
(Royal Society of Chemistry, 2017-09)
In the present work we have synthesized, via acid-base reaction between bis-(2-ethylhexyl)phosphoric acid (HDEHP) and 1-methylimidazole, a new protic ionic liquid: 1-methylimidazolium bis-(2-ethylhexyl) phosphate (imim-DEHP) ...
Optimal clarification of emulsified oily wastewater using a surfactant/chitosan biopolymer
(Elsevier Ltd, 2018-08)
The presence of emulsified oils in wastewater from the petroleum and petrochemical industry causes a significant environmental concern. The effect of chitosan (CH) and sodium dodecyl sulfate (SDS) doses on the destabilization ...
Radiolabeling and biological characterization of TPGS-based nanomicelles by means of small animal imaging
(Elsevier Science Inc, 2017-01)
Introduction In recent years, nanomedicines have raised as a powerful tool to improve prevention, diagnosis and treatment of different pathologies. Among the most well investigated biomaterials, D-α-tocopheryl polyethylene ...
Combination of protic ionic liquid-like surfactant and biocompatible solvents to generate environmentally friendly anionic reverse micelles
(Royal Society of Chemistry, 2019-06)
In the present work we have formulated environmentally friendly anionic reverse micelles (RMs) by the combination of a protic ionic liquid-like surfactant with biocompatible nonpolar solvents. Thus, the protic ionic liquid, ...
Síntese de nanolátex para aplicação como controlador de filtrado em cimentação de poços petrolíferos

New additives applied to wells cementing have been developed in search
of more and more efficient cement slurry systems for application in critical
scenarios, especially those cases where the risk of gas migration is ...
Rational design of nanocarriers based on gellan gum/retrograded starch exploiting polyelectrolyte complexation and ionic cross-linking processes: A potential technological platform for oral delivery of bevacizumab
(2021-12-01)
The structural fragility of monoclonal antibodies (mAbs), such as bevacizumab (BVZ), is a critical parameter for oral administration and can limit the use of several technologies to produce oral nanocarriers for these ...
