It was found that SBS modified bio-asphalt had higher viscosity than the base binder to some degree, and the effect of bio-oil on SBS bio-binder viscosity was small when the bio-oil content and testing temperature were high.
Herein, three new types of nano-GOs functionalized with polyethylene glycol (nGO-PEGs) were synthesized by varying the PEGylation degree, and their effects on Escherichia coli (E. coli) were carefully investigated.
In this study, one subway station in Beijing City is taken as the case, considering the unique features of urban development (e.g. high density and diversity), five objectives are taken to account in our model, including rail transit ridership, compactness, accessibility, conflict degree, and environmental effects.
