Functional groups on support membranes are important for the preparation of high-performance membrane adsorbers (MAs). In this work, effects different functional adsorption performance MAs were studied through surface modifications such as alkali treatment, oxidation treatment and polydopamine (PDA) deposition. Our experiment results indicate that chemical bonds prone to form between C-F PVDF a...

results the mean kt/v was 1.27 ± 0.28 in high-flux and 1.10 ± 0.32 in low-flux membrane which, these differences were statistically significant (p = 0.017). the mean of urr was 0.65 ± 0.09 in high-flux and 0.61 ± 0.14 in low-flux membrane, which these differences were not statistically significant (p = 0.221). patients and methods forty hemodialysis patients participated in this cross-over clin...

heterogeneous proton exchange membranes (pem) are synthesized using the dry phase inversion technique. the casting solutions are prepared by dispersing a finely ground cation exchange resin particle in n,n-dimethylacetamide (dmac) solution of polyvinyl-chloride (pvc). results show that ion exchange capacity is increased with the addition of 1 %-wt nanosilica (from 0.14 to 0.27 meq/g) while it i...

Dendrimers are exotic multi-functional ligands and expected to give rise better extraction/transport results as compared the mono-functional ligands. Diglycolamide (DGA) based dendrimers scarcely reported literature on their transport studies very limited. Transport of Am(III) Eu(III) across a PTFE (polytetrafluoroethylene) flat sheet supported liquid membrane containing generation 1 dendrimer ...

in this work a new resistance model has been presented based on that of henis-tripodi which can be used for interpretation of gas permeation data in composite and asymmetric membranes. in contrast to the previous works, in this model the fraction of the support layer surface that includes the pores filled with coating material has been taken into account. the influences of the filled pores on s...

Spontaneously occurring neuronal oscillations constitute a hallmark of developmental networks. They have been observed in the retina, neocortex, hippocampus, thalamus and spinal cord. In the immature hippocampus the so-called ‘giant depolarizing potentials’ (GDPs) are network-driven membrane oscillations characterized by recurrent membrane depolarization with superimposed fast action potentials...

Eukaryotic membrane proteins play many vital roles in the cell and are important drug targets. Approximately 25% of all genes identified in the genome are known to encode membrane proteins, but the vast majority have no assigned function. Although the generation of structures of soluble proteins has entered the high-throughput stage, for eukaryotic membrane proteins only a dozen high-resolution...

We present a continuum model trained on molecular dynamics (MD) simulations for cellular membranes composed of an arbitrary number lipid types. The is constructed within the formalism dynamic density functional theory and can be extended to include features such as presence proteins membrane deformations. This framework represents paradigm shift by enabling that access length scales order micro...
