The Mobilities of Electrons.
In a recent paper' it was shown that the electrons could presumably travel through N2 and H2 gases!in a free state at atmospheric pressure. It was found in some cases impossible to evaluate the mobilities of these electrons with the low frequencies of commutation available. The values of the mobilities indicated by these results appeared to be so much higher than the values obtained by earlier ...
متن کاملEditorial: Surveillance and Mobilities
The editorial introduces the pieces in this special issue on surveillance and mobilities. It draws out the key themes of the issue, asking: what is meant by ‘mobility’ and why it deserves such a focus; what are the goals and purposes of the surveillance of mobilities; and finally, what are the consequences. It proposes a simple typology of mobilities: ‘what moves’ (body, transactions, and artef...
متن کاملEditorial: Mobilities, Immobilities and Moorings
Mobility has become an evocative keyword for the twenty-first century and a powerful discourse that creates its own effects and contexts. The concept of mobilities encompasses both the large-scale movements of people, objects, capital and information across the world, as well as the more local processes of daily transportation, movement through public space and the travel of material things wit...
متن کاملChanges of Apparent Ionic Mobilities in Protoplasm
The normal P.D. across the protoplasm of Valonia macrophysa is about 10 mv. negative (inwardly directed). On adding 0.01 M guaiacol to the sea water the P.D. becomes positive and then slowly returns approximately to the normal value. In many cases this behavior is not much affected by raising the pH and so increasing the concentration of the guaiacol ion but in other cases such an increase make...
متن کاملMobilities of cation-macrocyclic ligand complexes
Formation constants for complexion between alkali metal cations and the crown ether 18C6 in the solvent 2-cyanopyridine at 3OoC were determined from conductance measurements. The method allows for precise determination of these formation constants up to values of K around 10" mol-' dm3. The method also f. permits accurate evaluation of association equilibrium constants between the complex speci...
