Synchronous Electrical Conductance‐ and Electron Tunnelling‐Scanning Electrochemical Microscopy Measurements

Scanning electrochemical microscopy, 52. Bipolar conductance technique at ultramicroelectrodes for resistance measurements.

The bipolar conductance, BICON, technique for the measurement of solution resistance, based on the application of microsecond current pulses, as originally described by Enke and co-workers for measurements with conventional electrodes, was extended for use with ultramicroelectrodes, with a focus on its application in scanning electrochemical microscopy (SECM). When the plateau time used to make...

Isolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy

Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...

Ultrathin Layer Cell for Electrochemical and Electron Transfer Measurements

An electrochemical cell based on electrodes of near-atomically-smooth platinum on mica surfaces with an interelectrode gap width (ro) adjustable with piezoelectric drive elements with a resolution of ca. 1 8, for distances of 0 to >500 nm is described. Measurements of the steady-state current for solutions of Fe(CN),3-/4show good agreement with electrochemical thin layer cell equations derived ...

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...
