The development of a new generation of membranes based on conducting polymers has been the subject of a recent line of research in the Department of New Materials at CIDETEC, in association with the LEIA Technological Centre.
This involves a field of work wherein the excellent advantages presented by electro-dialysis conventional membranes (continuous separation, low energy consumption, ease of combination with other separation processes, absence of additives) are combined with other, highly promising, properties shown by conducting polymer membranes, with special reference to the possibility of manipulation of the pore size by means of the application of potential differences. These developments target the increasingly specific demands from industrial sectors: surface coating/treatment sector (automobile, printing, locksmiths, machine-tools, etc.), chemicals, agricultural feeds, pharmaceuticals and textiles, etc.
The interest provoked by conducting polymers for their application in membrane technologies is explained when we look at the fundamental specification which an ion interchange membrane has to have: great selectivity, low electric resistance to minimise specific energy consumption and low electro-osmotic flow in order to obtain the maximum possible concentration of salts in the concentration compartment.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
