Talvez deva tentar algumas variações de ortografia:
transaction metals » transition metal (Expandir a busca), transitions metals (Expandir a busca), transaction level (Expandir a busca)
reactive reduction » reactive production (Expandir a busca), relative reduction (Expandir a busca), selective reduction (Expandir a busca)
reaction reduction » detection reduction (Expandir a busca), friction reduction (Expandir a busca), reaction equation (Expandir a busca)
oxygen reaction » oxygen reduction (Expandir a busca), oxygen reaeration (Expandir a busca), oxigen reactive (Expandir a busca)
of transaction » of translation (Expandir a busca)
of transition » of translation (Expandir a busca), of transmission (Expandir a busca), the transition (Expandir a busca)
metals oxygen » total oxygen (Expandir a busca)
complexes of » complex of (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Fazer uma busca fuzzy pode resultar em termos de grafias semelhantes: (( Macrocyclic complexes of transition metals oxygen reactive reduction ) OR ( macrocyclic complexes of transaction metals oxygen reaction reduction ))~.
• As palavras AND, OR e NOT pode ocasionar problemas na busca; tente utilizar as aspas: "(( Macrocyclic complexes of transition metals oxygen reactive reduction ) OR ( macrocyclic complexes of transaction metals oxygen reaction reduction ))".
• Adicionar um caractere curinga pode recuperar variações da palavra buscada: (( Macrocyclic complexes of transition metals oxygen reactive reduction ) OR ( macrocyclic complexes of transaction metals oxygen reaction reduction ))*.
