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.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
