| Summary: | The use of strong magnetic field gradients and high magnetic fields generated by permanent magnets or superconducting coils has found applications in many fields such as mining, solid state chemistry, biochemistry and medical research. Lab scale or industrial implementations involve separation of macro- and nanoparticles, cells, proteins, and macromolecules down to small molecules and ions. Most promising are those attempts where the object to be separated is attached to a strong magnetic nanoparticle. Here, all kinds of specific affinity interactions are used to attach magnetic carrier particles to mainly objects of biological interest. Other attempts use a strong paramagnetic suspension for the separation of purely diamagnetic objects, such as bio-macromolecules or heavy metals. The application of magnetic separation to superconducting inorganic phases is of particular interest in combination with ceramic combinatorial chemistry to generate a library of
e.g.
cuprate superconductors.

| Bibliography: | Mitra Iranmanesh received her PhD from University of Bern, Switzerland in 2015 where she conducted her research on synthesis of superconductors and magnetic separation with Prof. J. Hulliger. She was awarded a fellowship from the Swiss National Foundation (SNF) in 2016 and joined TANMS center at UCLA engineering school. Currently she is working with Prof. G. Carman on magnetostrictive thin films and their application in strain-mediated multiferroics devices. Jürg Hulliger was born in 1953 in Zurich, Switzerland. At ETH he studied chemistry and graduated in physical chemistry. In 1984 he received a PhD from the University of Zurich. After a post-doctoral stay at the State University of Pennsylvania, he moved to the institute of Solid State Physics at ETH to conduct research into crystal growth. In 1993 he took up his position as a full professor of chemistry at the University of Bern (Switzerland). His research fields are chemistry, physics and crystal growth of materials. Since 2004 Jürg Hulliger has been a fellow of the Royal Society of Chemistry. ObjectType-Article-2 SourceType-Scholarly Journals-1 ObjectType-Feature-3 content type line 23 ObjectType-Review-1 |
