In this thesis, we intend to develop the sol-gel technology (a chemical way to make glass) from the traditional "raw" materials side to a novel technology allowing realization of innovative products in the field of micro- and nanotechnology. We first prese ...
Bacteria, as well as higher organisms such as sea anemones or earthworms, have developed sophisticated virulence factors such as the pore-forming toxins (PFTs) to mount their attack against the host. One of the most fascinating aspects of PFTs is that they ...
The removal of natural organic matter (NOM) using nanofiltration (NF) is increasingly becoming an option for drinking water treatment. Low molecular weight LMW organic compounds are nevertheless only partially retained by such membranes. Bacterial regrowth ...
The growing demand for high levels of recombinant proteins of medical and pharmaceutical interest stimulates the development of cell bioprocess technology. Spin-filter technology is employed in order to reach high levels of such compounds. The aim of this ...
Evaluation of solar treatment in the absence and presence of TiO2 has been made to assess its effectiveness in reducing bacterial load with respect to drinking water standards. Field experiments under direct solar radiation were carried out using a compoun ...
This paper reports on the technology development and characterization of polyimide-based, microfluidic channels with integrated nanoporous membranes. A layer transfer and lamination technique is used to fabricate flexible microchannels from spin-on polyimi ...
An apparatus for retaining magnetic particles in self-assembled magnetic particle structures in a liquid flow, comprises a micro-channel (5) and magnets (1,2) for generating a substantially static magnetic field across the micro-channel (5) such that magne ...
A detrimental effect on the survival of bacteria Escherichia coli KI2 was observed after photocatalytic exposure. The reactions have been carried out in a batch photoreactor using mainly titanium dioxide (TiO2) P-25 Degussa as a catalyst. Illumination was ...
Compliance with the U.S. drinking water standard for arsenic (As) of 10 μg L-1 is required in January 2006. This will necessitate implementation of treatment technologies for As removal by thousands of water suppliers. Although a variety of such technologi ...
The spin-dependent transport in multiwall carbon nanotubes, obtained by chemical vapour deposition in porous alumina membranes, has been investigated. The zero-bias anomaly is shown to follow the typical power law GT(-alpha) (eV/kT). In the nanotubes conta ...
