Communications to the Editor mass number 235 showed that the intensities of the peaks at m/e 235.384 and 235.357 ([nB1310B71H22]+ and [11B1510B51H2o]+, respectively) diminished much more rapidly than that at m/e 235.315 ([11B101OB11H16]+). This(5) L.

Fig. 6. X-ray photoelectron spectroscopic analysis of chromium carbide coatings electroplated at various anode-cathode voltages and carbonate/chromium ratios: Cr2p region. (A): C032-/Cr = 0.26, VA_c = 0.50V: (B): C03Z-/Cr = 0.42, VA-c = 0.51V; (C) CO32-/Cr = 0.81, VA.c = 0.53V.solutions where K2CrO4 or Cr(III) is the source of chromium. Higher current efficiencies could probably be obtained if dendrite formation could be suppressed. Variables which could be manipulated are concentrations, voltage, and temperature.
