objective(s): in our study, graphene oxide-tio2 nanocomposite (go/tio2) was prepared and used for the enrichment of rutin from real samples for the first time. materials and methods: the synthesized go/tio2 was characterized by x-ray diffraction, scanning electron microscopy, and ft-ir spectra. the enrichment process is fast and highly efficient. the factors including contact time, ph, and...
Microbial mats are characterized by high primary production but low growth rates, pointing to a limitation of growth by the lack of nutrients or substrates. We identified compounds that instantaneously stimulated photosynthesis rates and oxygen consumption rates in a hypersaline microbial mat by following the short-term response (c. 6 h) of these processes to addition of nutrients, organic and ...
