NTL9 folding at constant pH: The importance of electrostatic interaction and pH dependence
(2016-07-12)
The folding process of the N-terminal domain of ribosomal protein L9 (NTL9) was investigated at constant-pH computer simulations. Evaluation of the role of electrostatic interaction during folding was carried out by including ...
pH dependence of the voltammetric response of Polyaniline
(Elsevier Science SA, 2017-01)
Voltammetric studies of Polyaniline (Pani) films were carried out in solutions of 3.7 M sulphate solutions of constant ionic strength and pH values comprised in the range between − 0.6 and 3.0. The results show that if the ...
Modeling the acid-base surface properties of aquatic sediments
(Springer, 2010-03)
We propose a model that explains the acid-base surface properties of clastic sediments from two Argentinean reservoir lakes. The model uses potentiometric titration data sets and fixed parameters such as the apparent ...
Self-Assembled Nanostructures of Peptide Amphiphiles: Charge Regulation by Size Regulation
(American Chemical Society, 2019-06)
Self-assembled nanostructures of peptide amphiphiles (PAs) with molecular structures C16K2 and C16K3 (where C indicates the number of carbon atoms in the alkyl chain and K is the lysine in the head group) were studied by ...
Non-monotonic behavior of weak-polyelectrolytes adsorption on a cationic surface: A Monte Carlo simulation study
(Elsevier, 2021-01)
In this work, the weak polyelectrolyte (PE) adsorption on a strong cationic surface is studied with constant pH Monte Carlo simulations using a coarse-grained model. When a large number of PE chains is added to the system, ...
Role of divalent cations, pH, Cytoskeleton components and surface charge on the adhesion of Trycomas Vaginalis to a polystyrene substrate
(Fundação Oswaldo Cruz. Instituto Oswaldo Cruz., 2020)
Lysozyme adsorption in pH-responsive hydrogel thin-films: the non-trivial role of acid-base equilibrium
(Royal Society of Chemistry, 2015-07)
We develop and apply a molecular theory to study the adsorption of lysozyme on weak polyacid hydrogel films. The theory explicitly accounts for the conformation of the network, the structure of the proteins, the size and ...
