Surface charge effects on the redox switching of LbL self-assembled redox polyelectrolyte multilayers
(Elsevier Science Sa, 2007-01-15)
The effect of surface charge on the electron transfer and charge propagation in layer by layer (LbL) electrostatically self-assembled redox poly-electrolyte multilayers (PEMs) has been studied. Thin films comprised of ...
Microphase separation and aggregate self-assembly in brushes of oppositely charged polyelectrolytes triggered by ion pairing
(American Institute of Physics, 2020-10)
This work applies a molecular theory to study the formation of lateral self-assembled aggregates in mixed brushes composed of polyanion and polycation chains. In order to overcome the well-known limitations of mean-field ...
Polyelectrolyte complexes for assisting the application of lignocellulosic micro/nanofibers in papermaking
(Springer, 2018-08)
A novel procedure based on the addition of polyelectrolyte complexes (PECs) onto the pulp containing lignocellulosic micro/nanofibers (LCMNF) is presented. This procedure allows increasing paper strength avoiding an excessive ...
Imim-DEHP reverse micelles investigated with two molecular probes reveals how are the interfacial properties and the coordination behavior of the surfactant
(Elsevier Science, 2020-09)
Aqueous reverse micelles (RMs) generated with the ionic liquid (IL)-surfactant 1-methylimidazolium bis-(2-ethylhexyl)phosphate (imim-DEHP) and the biocompatible solvents methyl laurate (ML) and isopropyl myristate (IPM) ...
Polyaniline for improved blue energy harvesting: Highly rectifying nanofluidic diodes operating in hypersaline conditions via one-step functionalization
(American Chemical Society, 2020-05-25)
Solid-state nanochannels have attracted substantial attention of the scientific community due to their remarkable control of ionic transport and the feasibility to regulate the iontronic output by different stimuli. Most ...
Chitosan-bovine serum albumin complex formation: A model to design an enzyme isolation method by polyelectrolyte precipitation
(Elsevier Science, 2010-06)
Interactions between a model protein (bovine serum albumin-BSA) and the cationic polyelectrolyte, chitosan (Chi), have been characterized by turbidimetry, circular dichroism and fluorescence spectroscopy. It has been found ...
A Comprehensive and Comparative Analysis of the Fucoidan Compositional Data Across the Phaeophyceae
(Frontiers Media, 2020-11)
In the current review, compositional data on fucoidans extracted from more than hundred different species were surveyed through the available literature. The analysis of crude extracts, purified extracts or carefully ...
Ethanol adsorption on MgO surface with and without defects from a theoretical point of view
(Elsevier Science, 2009-04-20)
In this work, the ethanol adsorption on a perfect MgO(1 0 0) surface, and also on topologic surface defects of MgO, is studied. Terrace, edge and corner sites were analyzed, whose O and Mg ions are five, four and three ...
