With sensitivity being the Achilles? heel of nuclear magnetic resonance (NMR), the superior mass sensitivity offered by micro-coils can be an excellent choice for tiny, mass limited samples such as eggs and small organisms. Recently, complementary metal oxide semiconductor (CMOS)-based micro-coil transceivers have been reported and demonstrate excellent mass sensitivity. However, the ability of broadband CMOS micro-coils to study heteronuclei has yet to be investigated, and here their potential is explored within the lens of environmental research. Eleven nuclei including 7Li, 19F, 31P and, 205Tl were studied and detection limits in the low to mid picomole range were found for an extended experiment. Further, two environmentally relevant samples (a sprouting broccoli seed and a D. magna egg) were successfully studied using the CMOS micro-coil system. 13C NMR was used to help resolve broad signals in the 1H spectrum of the 13C enriched broccoli seed, and steady state free precession was used to improve the signal-to-noise ratio by a factor of six. 19F NMR was used to track fluorinated contaminants in a single D. magna egg, showing potential for studying egg?pollutant interactions. Overall, CMOS micro-coil NMR demonstrates significant promise in environmental research, especially when the future potential to scale to multiple coil arrays (greatly improving throughput) is considered. |

The objective of this study was to research the cassava production chain in Araguaia Valley Region (Goias state, Brazil) from the perspective of the Transaction Costs Economics. The Araguaia Valley Region comprises the municipalities of Aruana, Britania, Buriti de Goias, Corrego do Ouro, Fazenda Nova, Itapirapua, Jussara, Matrincha, Montes Claros de Goias, Novo Brasil and Santa Fe de Goias. The region has an area of 18,451 square kilometers and a population of about 72,000 inhabitants (26% living in rural areas). |
