  1. An #OpenSource, low-cost multinuclear #NMR #spectrometer operating in the mT field regime:

    -high spectral resolution
    -arbitrary #RF pulse programming
    -requires #LabVIEW
    -cost: k$ 20 (mainly PXI waveform generator & digitizer alone)
    -cost could be driven down by half using a home-built RF amplifier made with high-power operational amplifiers

  2. #cNMR: #OpenSource compact time-domain hydrogen (1H) #NMR system for field deployment:

    -based on a 0.5 T permanent magnet
    -emphasizes relaxation times rather than chemical shifts, enabling material property analysis without large magnets or complex spectral processing
    -requires #LabVIEW
