Environmental Comprehensive Multiphase NMRreference-entry
Аннотация: Comprehensive multiphase (CMP)-NMR spectroscopy provides the ability to study all bonds in all phases in natural, unaltered samples. CMP-NMR probes comprise a lock, magic-angle gradients, magic-angle spinning, are fully susceptibility matched and use high-power circuitry to permit the full range of solution-, gel-, and solid-state NMR experiments. As such, it represents a key step forward in environmental research, where, for example, the overall properties of a soil are of environmental relevance and understanding complex associations, aggregations, interactions, and reactions in situ are the key to unravel its environmental properties. CMP-NMR spectroscopy allows the transfer, kinetics, degradation, and interactions of contaminants between phases to be elucidated and monitored in real time. Materials with complex multiphase structure such as plants, air particles, sediments, soils and tissues are ideally suited to CMP-NMR analysis. Processes that convert one phase into another, for example, the conversion of biomass to bioethanol, can also be probed in detail by CMP-NMR spectroscopy. CMP-NMR spectroscopy will likely find widespread application not only in environmental research but also in fields such as medicine, biochemistry, biology, heterogeneous catalysis, or any other area that deal with samples containing more than one phase.
