NMC and the carbon black were first mixed in a planetary ball mill for hours, followed by addition of the dissolved binder and then further mixed for 1 hour. The slurry was thereafter coated on a carboncoated aluminum sheet and dried at 120°C. The mass loadings ranged between mg/cm 2 for the dried electrodes.

GasSensing Membrane Electrodes; Biocatalytic Membrane Electrodes; The electrodes in Chapter are selective toward ions. In this section we consider how we can incorporate an ionselective electrode into an electrode that responds to neutral species, such as volatile analytes, such as CO 2 and NH 3, and biochemically important compounds, such as amino acids and urea.

Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...
