We employ 50 ns molecular dynamics simulations to study the distribution, orientation, and of 1,6-diphenyl-1,3,5-hexatriene (DPH) fluorescent probes in a dipalmitoylphosphatidylcholine (DPPC) bilayer. find no evidence for clustering DPH molecules, our results show that does not prefer be embedded membrane center where free volume is largest. Rather, prefers accommodated hydrophobic acyl chain region DPPC, oriented such long axis along its rodlike shape approximately aligned direction bilayer...
We consider the properties of free pyrene probes inside gel- and fluidlike phospholipid membranes unravel their influence on membrane properties. For this purpose, we employ atomic-scale molecular dynamics simulations at several temperatures for varying concentrations. Molecular show that molecules prefer to be located in hydrophobic acyl chain region close glycerol group lipid molecules. Their orientation is shown depend phase membrane. In fluid phase, pyrenes favor orientations where they...
We have used atomistic molecular dynamics simulations to consider 1,6-diphenyl-1,3,5-hexatriene (DPH) fluorescent probes in a fluid dipalmitoylphosphatidylcholine bilayer with 5 and 20 mol % cholesterol (CHOL). show that while DPH affects number of membrane properties, the perturbations induced by depend on concentration membrane. For example, we find influence mass density distribution lipids across promote ordering acyl chains around probe. Yet, these get relatively weaker for increasing...
Abstract Antimicrobial polyvinylidene fluoride (PVDF) membrane modified by dodecyltrimethyl ammonium bromide (DTAB) has been electrospun using simple one‐step technology, where the modifying agent DTAB is dissolved in spinning solution. X‐ray photoelectron spectroscopy and electrokinetic analysis confirm reliably presence of on nanofibers surfaces; shows changes zeta potential due to modification DTAB. diffraction that electrospinning converts part α phase (≈40%) present PVDF powder into β...
Abstract Natural Na-montmorillonite (MMT) with the formula (Na0.67K0.01Ca0.02)(Al2.90Mg0.59 Fe3+ 0.49Ti0.01)(Si7.92Al0.08)O20(OH)4was intercalated octadecylamine (C18H39N) (ODA) varied MMT/ODA ratios. The basal spacings d(00l) of natural and Na-MMT ODA were determined by XRD analysis. set diffractions: d(001) = 56 Å, d(002) 28 d(003) 18 d(004) 14 d(005) 11 Å for saturated Na-MMT/ODA intercalate indicates existence highly ordered periodic structure double-layer in silicate interlayer spacing....
