You are cordially invited to the 20th Topical Meeting of the International Society of Electrochemistry, which will be held in Buenos Aires, Argentina from 19 to 22 March 2017. Buenos Aires, located on the western shore of the estuary of the Rio de la Plata, is the cosmopolitan capital of Argentina, known for its European atmosphere, passionate tango and vibrant nightlife. It has a population of about 3.5 million and is lively all year round with plenty of cultural activities, long tradition in visual arts with many important art galleries and museums. Every April one of the top five book fairs in the world is celebrated in the city, oriented to general public as well as to the literary community. Buenos Aires defines itself as a multicultural city, being home to multiple ethnic and religious groups. Since the end of the 19th century the city, and the country in general, has been a major recipient of millions of immigrants from around the world, particularly from Italy and Spain and Latin America, and more recently from Asia, making it to be considered as one of the most diverse cities in Latin America. From Buenos Aires you can visit some of the most fascinating places of Argentina, such as the near infinite flat lonely pampas, the splendid Iguazu waterfalls, the multicoloured mountains in the highs of the northern Puna, the stunning glaciers in the south or the sparsely populated, steppe-like plains of Patagonia.
