Direct-current plasma-assisted

NiO nanowalls were S3mthesized directly on the nickel foil by the plasma assisted oxidation method. The height of the nanowall is over 100 nm, the thickness is less than 40 nm. The first discharge capacity at the current rate of 448 mA/g is 1253 mAh/g and the reversible capacity is 794 mAh/g. When increasing the current density to 895 and 1343 mA/g, the reversible capacities were 833 and 506 mAh/g, respectively. It shows good capacity retention capability at different current rates. ... 

Mass Spectrometric Detection. The very small volumetric flow rates of less than 1 pi,/min from electrophoresis capillaries make it feasible to couple the effluent directly to the Ionization source of a mass spectrometer. The most common sample-introduction and ionization interface for this purpose is currently electrospray (Section 20B-4), although fast atom bombardment, matrix-assisted laser desorption-ionization (MALDI) spectrometry, and inductively coupled plasma mass spectrometry (ICPMS) have also been used. Because the liquid sample must be vaporized before entering the mass spectrometry (MS) system.
