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.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
