Impedance spectroscopy and membrane potential analysis of microfiltration membranes. The influence of surface fractality
(Pergamon-Elsevier Science Ltd, 2018-03)
In this work, the proper charge density of a microfiltration membrane has been determined by using two different methods. Firstly, the ionic transport of a KCl solution has been investigated by simultaneous measurements ...
Structural basis of molecular recognition of the Leishmania Small Hydrophilic Endoplasmic Reticulum-associated Protein (SHERP) at membrane surfaces
(Elsevier, 2011)
The 57-residue small hydrophilic endoplasmic reticulum-associated protein (SHERP) shows highly specific, stageregulated expression in the non-replicative vector-transmitted stages of the kinetoplastid parasite, Leishmania ...
Xylene isomerization in a ZSM-5/SS membrane reactor
(Springer, 2008-06)
A membrane reactor containing different types of ZSM-5/porous SS membranes was used to perform the xylene isomerization reaction. The parent Na-ZSM-5 layer was synthesized by secondary growth on top of porous stainless ...
Membrane localization of Junín virus glycoproteins requires cholesterol and cholesterol rich membranes
(Academic Press Inc Elsevier Science, 2013-01)
Arenavirus morphogenesis and budding occurs at cellular plasma membrane;however, the nature of membrane assembly sites remains poorly understood. In this study we examined the effect of different cholesterol-lowering ...
Interaction of a polyarginine peptide with membranes of different mechanical properties
(Multidisciplinary Digital Publishing Institute, 2019-10)
The membrane translocation efficiency of cell penetrating peptides (CPPs) has been largely studied, and poly-arginines have been highlighted as particularly active CPPs, especially upon negatively charged membranes. Here ...
Breakdown of classical paradigms in relation to membrane structure and functions
(Elsevier Science, 2021-02)
Updates of the mosaic fluid membrane model implicitly sustain the paradigms that bilayers are closed systems conserving a state of fluidity and behaving as a dielectric slab. All of them are a consequence of disregarding ...
Acid-doped ABPBI membranes prepared by low-temperature casting: Proton conductivity and water uptake properties compared with other polybenzimidazole-based membranes
(Electrochemical Society, 2016-01)
Phosphoric acid doped ABPBI (poly [2,5-benzimidazole]) membranes were prepared with a new low temperature casting procedure (ABPBI-ET), and their water uptake and proton conductivity were measured. The results were compared ...
Properties of polyethersulfone ultrafiltration membranes modified with polyethylene glycols
(John Wiley & Sons Inc, 2013-04)
Polyethersulfone ultrafiltration membranes have been prepared using polyethylene glycols (PEGs) of 400, 1000, and 10,000 gmol, as additive with dimethylacetamide as solvent. Infrared analysis proves that PEG leaves almost ...
Efficient Removal of Heavy Metals from Aqueous Solutions through Functionalized γ-Graphyne-1 Membranes under External Uniform Electric Fields: Insights from Molecular Dynamics Simulations.
(American Chemical Society, 2021)
Carbon-based nanosheet membranes with functionalized pores have great potential as water treatment membranes. In this study, the separation of Hg(2+) and Cu(2+) as heavy metal ions from aqueous solutions using a functionalized ...
Trans-membrane Fluorescence Enhancement by Carbon Dots: Ionic Interactions and Energy Transfer
(American Chemical Society, 2019-06)
We report on trans-membrane interactions between blueemitting carbon dots (CDs) and fluorescein. Hydrophobic CDs with a positive surface charge are embedded as-synthesized in the lipophilic sheet of the bilayer membrane ...
