“…One of the most important cerium compounds and the most widely employed is cerium (IV) oxide, also known as ceria, a non-natural, ionic solid which crystallizes the ongoing research about ceria mostly orbits in areas, such as heterogeneous catalysis, photocatalysis, fuel cell technology and biological mimetization. [87] The most unique property of ceria relies on the fact that it is prone to form oxygen vacancies defects, making it suitable for reduction-oxidation processes and catalytic activity systems. Such oxygen vacancy defects improve the oxygen diffusion rate in the ceria lattice, and considerably assist in the high performance of the catalytic reactions.…”

Antonio Pigafetta, a Florentine navigator who went with Magellan on the first voyage around the world, wrote, upon his passage through our southern lands of America, a strictly accurate account that nonetheless resembles a venture into fantasy. In it he recorded that he had seen hogs with navels on their haunches, clawless birds whose hens laid eggs on the backs of their mates, and others still, resembling tongueless pelicans, with beaks like spoons. He wrote of having seen a misbegotten creature with the head and ears of a mule, a camel's body, the legs of a deer and the whinny of a horse. He described how the first native encountered in Patagonia was confronted with a mirror, whereupon that impassioned giant lost his senses to the terror of his own image. This short and fascinating book, which even then contained the seeds of our present-day novels, is by no means the most staggering account of our reality in that age. The Chronicles of the Indies left us countless others. Eldorado, our so avidly sought and illusory land, appeared on numerous maps for many a long year, shifting
