Proceedings of the Eleventh Latin American Conference on the Applications of the Mössbauer Effect, La Plata, Argentina, 9-14 November 2008.
The broad scope of the Applications of the Mössbauer Effect to interdisciplinary subjects makes this volume an outstanding source of information to researchers and graduate students, who will find the unique results of Mössbauer spectroscopy a valuable aid and complement to their research in conjunction with other techniques. In this volume, applications to mineralogy, catalysis, soil science, amorphous materials, nanoparticles, magnetic materials, nanotechnology, metallurgy, corrosion, and magnetism, have been put together in original works produced by invited speakers and different research teams across the continent.
