Over the past few years there has been great progress in electrochemistry in Spanish and Portuguese speaking countries. This Special Issue contains a small fraction of the papers presented at the XXI meeting of the Iberoamerican Electrochemical Society (Sociedad Iberoamericana de Electroquimica, SIBAE) that was held in La Serena, Chile from April 6 to April 11, 2014. La Serena is the second largest beach resort in Chile. The skies of northern Chile are known around the world for their sharpness. Not far from La Serena are located several world class observatories featuring some of the largest telescopes in the world.

The SIBAE Meeting is organized every two years and gathers scientists working in electrochemistry mostly from Latin America, Spain and Portugal. Meetings are held both in the Americas and in Europe. Chairman of this meeting was Dr. Soledad Bollo and the scientific committee was headed by Dr. Arturo Squella. The meeting featured six plenary lectures by: Dr. Gerardine Botte, Ohio University; Dr. Gustavo Rivas, Cordoba University, Argentina; Dr. Laurie Peter, University of Bath, United Kingdom; Dr. Ignacio Sires, University of Barcelona, Spain; Dr. Carmen Andrade Perdrix, National Research Council of Spain; and Dr. Daniel Belanger, Université de Quebec, Montreal, Canada.

A total of 435 papers were presented including 15 semi-plenary lectures, 161 oral presentations and 274 poster presentations which were distributed among the following Symposia: (i) electrochemical energy conversion, (ii) corrosion and electrodeposition, (iii) electroanalysis, industrial and environmental electrochemistry, (iv) electrochemistry of materials, (v) fundamental electrochemistry and (vi) molecular electrochemistry and bioelectrochemistry.

We heartily thank Prof. Gerardine Botte and Dr. Kenneth Howell for offering the possibility of publishing this special issue for the first time after a SIBAE Meeting. We are also deeply grateful to all authors and reviewers for their effort and time. Guest Editors: José H. Zagal and Ricardo Schrebler.
