Vicente Seabra Telles e a criação da nomenclatura em português para a Química 'Nova' de Lavoisier

In 1787, Lavoisier and coworkers published a 314-page book entitled Méthode de nomenclature chimique in which a novel system for the naming of compounds and elements was presented. The Brazilian chemist Vicente Coelho de Seabra Telles (1764-1804) was responsible for translating it into Portuguese. Telles proposed the adoption not only of the Latin etymology, but decided to use Latin suffixes as well, because of the similarity between Latin and the Portuguese language. In doing so, he made the names of the compounds in Portuguese bear a closer resemblance to the names in Latin than to those in French or Spanish.

A etimologia de biomoléculas com metais de transição como auxiliar na aprendizagem de Química Biológica

Numerous functional biomolecules are associated with metals, i.e. the metallobiomolecules; more specifically, some are dependent on transition metals required for several crucial biological roles. Nevertheless, their names can lead to ambiguous interpretations concerning the properties and performances of this group of biological molecules. Their etymology may be useful by providing a more perceptive insight into their features. However, etymology can lead to incongruous conclusions, requiring an especially careful approach to prevent errors. Examples illustrating these subjects shall be examined.
