In the present study, the corrosion potential （Eco,） behavior of the duplex SS UNS S32760 was recorded simultaneously with the in situ marine biofilm formation in two areas at Arraial do Cabo, Southeastern Brazil. The biofilm at Forno Harbor （an anthropogenically disturbed area） was characterized by higher relative abundances of Bacteria at day 2, followed by diatoms （especially Navicula sp.） on day 10 and dinoflagellates on day 18, whereas no clear trend was recorded at Cabo Frio Island （an undisturbed area）. The ennoblement of Ecor values was site-dependent. In a complementary laboratory assay, biofilms were removed and the Eco values registered in sterile conditions for the subsequent 10 days and corroborated in situ results. Understanding biofilms and SS interactions has important implications for materials science and engineering decisions as well as helping to fill in imnortant gaps in this knowledge.展开更多

The criticism pointed out the way for the solution of the ecological problems and showed the seeds of ecological civilization. The paper reveals the ontology about ecological civilization and generation and elimination of crisis through analyzing the Marxist thought of ecological civilization in manuscripts. The paper believes that Marxist thought of ecological civilization may enlighten us to carry forward and develop it with guidance, sense and theory. We sincerely expect that the thought of ecological civilization will be rooted in the hearts of the people deeply by means of the rise of ＂green＂ concept and the education of ecological ethics. The paper has important theoretical and practical value on deeply understanding the relationship between human and nature with scientific development angle of view, conquering the ecological crisis of globalization scientifically and building and developing ecological civilization of Chinese characteristic socialism energetically.展开更多
