Modeling of batch and semi-batch membrane filtration processes

A mathematical frame for modeling batch and semi-batch membrane filtration processes is provided. The approach followed in this work uses the feed concentrations as a basis for the calculations, rather than the concentration factor. A practical computation ...

Memory effects of ion-selective electrodes: Theory and computer simulation of the time-dependent potential response to multiple sample changes

Nico de Rooij

A straightforward theoretical description of the time-dependent response of ion-selective membrane electrodes to multiple sample changes is presented. The derivation makes use of an approximation for the ion fluxes in the membrane, and of the superposition ...

Single-molecule motions of oligoarginine transporter conjugates on the plasma membrane of Chinese hamster ovary cells

Hui Wang

To explore the real-time dynamic behavior of molecular transporters of the cell-penetrating-peptide (CPP) type on a biological membrane, single fluorescently labeled oligoarginine conjugates were imaged interacting with the plasma membrane of Chinese hamst ...

In situ fabrication of a polyacrylamide membrane in a microfluidic channel

Martinus Gijs, Virendra Kumar Parashar, Jean-Baptiste Robert Orhan

We present a novel technological approach for the in situ realization of a micron-thin poly-acrylamide membrane in the center of a microfluidic channel. The membrane is formed by interfacial polymerization of an inner stream of monomer solution in between ...

Reusability of nanostencils for the patterning of Aluminum nanostructures by selective wet etching

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

One of the major advantages of stencil lithography is the possibility to use stencils many times. However, when stencils contain nanoapertures, the clogging of the membranes limits the useful life time of the stencils. The clogging is due to the accumulati ...
