This is a specialized scientific term primarily used in crystallography, materials science, and solid-state physics. It is universally understood in academic and industrial settings in both Brazil and Portugal. The term 'unit cell' is often preferred in English-language scientific publications, though 'elementary cell' remains a valid and historically significant term. In Brazil, both 'célula elementar' and 'célula unitária' are accepted in academic contexts.
