Abstract

nanofluídos. a presente invenção refere-se a um nanofluído fabricado por irradiação nuclear de uma mistura que compreende um precursor e um fluido de base. a invenção se estende a um método de fabricação do nanofluído. a invenção também se estende a um sistema para utilização na fabricação do nanofluído. a combinação da dosagem de irradiação uniforme resulta em substancialmente nenhuma sedimentação das nanopartículas suspensas. observou-se que o nanofluído formado possui melhores propriedades em comparação com aqueles conhecidos na técnica.
