This paper compares the polarization losses associated with the various diffusion-reaction-conduction processes in molten carbonate cathodes. The comparisons are made by estimating each type of loss in terms of component electrochemical potentials in joules/mole; this allows diffusive, charge-transfer, and ohmic losses to all be put on equal footing. For characteristic parameter values, diffusi...

Constrained by large ohmic and radiation losses, plasmonic nanolasers operated at visible regime are usually achieved either with a high threshold (10(2)-10(4) MW cm(-2)) or at cryogenic temperatures (4-120 K). Particularly, the bending-back effect of surface plasmon (SP) dispersion at high energy makes the SP lasing below 450 nm more challenging. Here we demonstrate the first strong room tempe...

We investigated the electron transport properties of n-GaN under an Ohmic-metal. Hall measurement results were compared for (A) before Ti-based metal deposition, (B) after deposition but annealing, (C) Ohmic and (D) Ohmic-metal removal, where multi-probe-Hall device measurements are required (C), while others, (A), (B), (D), can be characterized by conventional measurements. The elucidated that...

in this research the effect of conventional and ohmic pasteurization and storage time at different temperatures on some bioactive components of aloe vera gel juice was investigated. aloe vera gel juice was pasteurized conventionally and ohmically at 90 ºc for 1 min. the effect of pasteurization on vitamin c, total phenolic content  and juice color was evaluated. the samples pasteurized conventi...

In the Winterberg scheme, a charge neutralized intense high-Z ion beam is axially injected into a mirror magnetic field, where it undergoes isothermal compression without significant loss of forward beam velocity. During compression , an azimuthal current is induced in the beam which then leads to ohmic heating of the beam. Simultaneously, the beam density increases to a collision dominated reg...

The influence of a coaxial dielectric rod on eigenvalues, ohmic losses, transverse field structure, and beam-wave coupling coefficients is investigated for TE modes gyrotron cavity. It shown that such insert, when made from moderate-loss material, results in strong attenuation all cavity modes, with the exception those having caustic radii much larger than insert radius. proposed to employ load...
