New lives for old reverse osmosis (RO) membranes

The overall objective of the present work was to estimate by membrane autopsy the level of performances degradation of old reverse osmosis (RO) membranes/modules in order to envisage their reuse A mechanistic approach using the Spiegler-Kedem-Karchalsky mo ...

2010

Structure and thermodynamics of crystalline membranes are characterized by the long-wavelength behavior of the normal-normal correlation function G(q). We calculate G(q) by Monte Carlo and molecular dynamics simulations for a quasiharmonic model potential ...

One of the key factors to obtain large displacements and high efficiency with dielectric electroactive polymer (DEAPs) actuators is to have compliant electrodes. Attempts to scale DEAPs down to the mm or micrometer range have encountered major difficulties ...

Making giant unilamellar vesicles via hydration of a lipid film

Suliana Manley

This unit describes protocols for making giant unilamellar vesicles (GUVs) based on rehydration of dried lipid films. These model membranes are useful for determining the impact of membrane and membrane-binding components on lipid bilayer stiffness and pha ...

Numerical simulation and optimization of multi-step batch membrane processes

A simple numerical technique is presented for batch membrane filtration design. The underlying model accounts for variable solute rejection coefficients, and it has a modular structure which permits to easily describe the batch process involving different ...

IMPROVED LARGE-AREA AND HIGH-DENSITY NANOSTENCIL LITHOGRAPHY

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. Currently, large area pattern transfer using nanostencil lithography is ...

Two-phase partition profiling of drugs and ionisable compounds

Lipophilicity of compounds with therapeutic interest represents one of the most important physicochemical parameters in predicting and interpreting transport processes across biological barriers. This property is commonly measured as a drug | membrane part ...

Permeation liquid membrane as a tool for monitoring bioavailable Pb in natural waters

In order to predict metal bioavailability by microorganisms in natural waters, analytical speciation techniques such as the permeation liquid membrane (PLM) are required. A planar sheet PLM has been characterized by measuring Pb fluxes in the absence and p ...

Study of polyelectrolyte complex formation applying the synthetic boundary technique of analytical ultracentrifugation

Jutta Christine Wandrey, David Hunkeler

Polyelectrolyte complex membrane formation has been studied, online, using the synthetic boundary technique of an Optima XL-I anal. ultracentrifuge. This recent method, established by the first author, has now been evaluated concerning its sensitivity to m ...

Membrane interaction of TNF is not sufficient to trigger increase in membrane conductance in mammalian cells

Françoise Gisou van der Goot Grunberg

Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
