Not just in terms of performance (e.g. time to completion), but also in terms of power consumed to complete these necessary tasks. At the system… (More)
Surface enhanced Raman spectroscopy using a gold substrate and excitation at 514 nm can detect sub parts per million quantities of asphaltene and thereby petroleum. This simple format and sensitivity make it transformative for applications including sample triage, flow assurance, environmental protection and analysis of unique one of a kind materials.
