Ammonia losses during swine wastewater treatment were examined using single- and two-chambered microbial fuel cells (MFCs). Ammonia removal was 60% over 5 days for a single-chamber MFC with the cathode exposed to air (air-cathode), versus 69% over 13 days from the anode chamber in a two-chamber MFC with a ferricyanide catholyte. In both types of systems, ammonia losses were accelerated with ele...

A novel lithium ion sulfur battery is formed by coupling an activated ordered mesoporous carbon-sulfur (AOMC-S) cathode and a nanostructured tin-carbon anode. The lithium ion cell has improved reversibility, high energy content and excellent cycle life.

Full simulation of the CDC cathode data is made with the image charge method and ion statistical model. The model well reproduces the actual cathode charge distribution and shows reasonable agreement of the spatial resolution with the measurement. The simulation code is implemented in GSIM and lls raw data table, hence this can be used in studying tracking trigger and developing reconstruction ...

We present here measurements of plasma display panel PDP ignited by SrO and SrCaO cold cathodes with high yield of ion-induced secondary electron emission high i . SrOand SrCaO-cathode PDPs attain high luminous efficacy at low applied voltage, where the breakdown voltage is 30% lower than that of ordinary MgO-cathode PDP. Current and emission measurement clearly demonstrates that SrOand SrCaO-c...

The time evolution of soft modes in a quantum gauge field theory is to first approximation classical, but the equations of motion are non-local. We show how they can be written in a local and Hamiltonian way in an Abelian theory, and that this formulation is particularly suitable for numerical simulations. This makes it possible to simulate numerically non-equilibrium processes such as the phas...

Cathode spot motion influences the physical characteristics of arc plasma and the related macroparticles (MPs) in resultant films; these MPs limit the application of arc ion plating (AIP). In this paper, a scanning radial magnetic field (SRMF) was applied to the cathode surface to control the cathode spot motion and reduce the MP contamination in the deposited films. It was shown that film surf...
