NMR imaging of salt-water ice
Abstract Salt-water ice was imaged in a 2Tesla, horizontal 310 mm bore NMR imaging system at 85 MHz. 50 mm diameter ice cylinders were placed in a temperature-controlled chamber in the NMR system and imaged at temperatures from −20° to 0°C. Paramagnetic Cu 2 SO 4 at a low concentration was added to...
