Disease relevance of Electric Conductivity

 

High impact information on Electric Conductivity

  • Here we report the percolation threshold for molten iron-sulphur compounds of approximately 5 vol.% in solid olivine, based on electrical conductivity measurements made in situ at high pressure and temperature [5].
  • The I(V) characteristics of MIM structures formed with these SAMs are measured and simulated according to theoretical tunneling models for electrical conductivity through thin organic layers [6].
  • Our electrical conductivity measurements of fluid oxygen under dynamic quasi-isentropic compression show that a nonmetal-metal transition occurs at 3.4 fold compression, 4500 K, and 1.2 Mbar [7].
  • Measurements of the mass uptake, thickness change, and electrical conductivity of such composites indicate that swelling of the polymer film, and thus its normalized resistance response, is beyond that expected by mass uptake alone upon exposure to acetic acid vapor [8].
  • This, along with a favorable electric conductivity of the carrier electrolyte solution, contributed to a 20 nmol/L (2.5 ppb) limit of detection for bromate in the CZE stage [9].

Anatomical context of Electric Conductivity

 

Associations of Electric Conductivity with chemical compounds

  • They enhanced the electrical conductivity of the medium only slightly so that a new cell electrophoresis separation medium could be prepared, which contained 30 mM NaCl together with or without 1 mM CaCl2 but did not generate problems of overheating the fluid [20].
  • Electrical conductivity across a polyacrylamide-filled capillary decreases during the separation of DNA sequencing fragments [21].
  • This is consistent with electrical conductivity measurements, which demonstrate that this material is highly sensitive to the presence of a reducing gas such as carbon monoxide [22].
  • Mesoporous silicon doped with 3.0 x 10(19) B atoms cm-3 (p(+)-type) is an insulating material which dramatically increases its electrical conductivity when exposed to traces of gaseous NO2; nitrogen dioxide chemisorption at the surface generates carriers, the population of which is readily evaluated through the intensity of IR absorption [23].
  • Electrical conductivity measurements of neutral phenyl viologen, the first such measurements of a neutral viologen, reveal that it is a significantly better conductor than the radical cation [24].
 

Gene context of Electric Conductivity

  • Culture medium containing up to 100 ng/ml of IL-1 beta or IL-6 was inoculated with A. actinomycetemcomitans (serotypes a, b and c) or P. gingivalis and growth was monitored by measuring changes in electrical conductivity every 3 min for up to 48 h [25].
  • Cell model calculations for the electrophoretic mobility, electrical conductivity and sedimentation potential in concentrated suspensions of colloidal particles with low zeta potentials are reviewed with particular emphasis on an Onsager relation between sedimentation potential and electrophoretic mobility [26].
  • In this study, soil organic carbon was extracted with electrolytes (deionized H2O and Na- or Ca-based electrolytes) of electrical conductivity bracketing those found in Delta leaching and runoff conditions [27].
  • CONCLUSION: Changes in FFM, assessed by total body electrical conductivity, were different from the results obtained by classic nitrogen balance [28].
  • The resulting TEM specimens have a self-supporting structure, good thermal and electrical conductivity while showing a well-polished surface resulting from the ion milling process [29].
 

Analytical, diagnostic and therapeutic context of Electric Conductivity

  • PURPOSE: To determine whether combining acetic acid instillation before radiofrequency (RF) ablation can improve local tissue electrical conductivity, RF energy deposition, intratumoral heating, and tumor necrosis in a large animal model [30].
  • The rate of OH radical-induced strand break formation of single-stranded poly(U) in N2O/O2-saturated aqueous solution was studied by measuring the time-dependence of the electrical conductivity following pulse radiolysis [31].
