Separation properties of supported ionic liquid-polydimethylsiloxane membrane in pervaporation process

Pervaporation separation properties of water-butan-l-of binary mixtures were measured with the use of three supported liquid membranes at 37 C, namely PDMS, 1-ethenyl-3-ethyl-imidazolium hexafluorophosphate-PDMS, and tetrapropyl-ammonium tetracyanoborate-P ...

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 ...

The multiple roles of PtdIns(4)P - not just the precursor of PtdIns(4,5)P2

Giovanni D'Angelo

The phosphoinositides (PIs) are membrane phospholipids that actively operate at membrane-cytosol interfaces through the recruitment of a number of effector proteins. In this context, each of the seven different PI species represents a topological determina ...

Proteome analysis of the plasma membrane of Mycobacterium tuberculosis

Stewart Cole

The plasma membrane of Mycobacterium tuberculosis is likely to contain proteins that could serve as novel drug targets, diagnostic probes or even components of a vaccine against tuberculosis. With this in mind, we have undertaken proteome analysis of the m ...

Computer simulation of uranyl uptake by the rough lipopolysaccharide membrane of pseudomonas aeruginosa

Matteo Guglielmi

Heavy metal environmental contaminants cannot be destroyed but require containment, preferably in concentrated form, in a solid or immobile form for recycling or final disposal. Microorganisms are able to take up and deposit high levels of contaminant meta ...

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 ...

A high-performance compact electromagnetic actuator for a PMMA ball-valve micropump

Martinus Gijs, Christophe Yamahata, Meng Shen

We present the microfabrication and characterization of a reciprocating-type poly(methylmetacrylate) (PMMA) ball-valve micropump which is actuated with a high-performance and compact electromagnetic circuit of centimeter size. We have improved by finite el ...
