Synchrotron X-ray tomography and scanning electron microscopy were applied to elucidate the spatial distribution of discharge product (NaO2) in the carbon cathode of sodium-oxygen batteries. Various batteries were discharged galvanostatically and their cathodes were analyzed. We observe a particle density gradient along the cathode that scales with the current density applied. Besides, we show ...
This paper proposes a novel design for hybrid engine air-particle separator filter (HEAPS) that combines the vortex tube (VTS) with inertial particle (IPS) to enhance separation efficiency. Helicopters often operate in harsh environments, such as deserts, and landing on unprepared runways poses severe risk turboshaft engines due ingestion of dust sand. can result significant damage engine's rot...
Separators are used to protect cathodes from biofouling and to avoid electrode short-circuiting, but they can adversely affect microbial fuel cell (MFC) performance. A spray method was used to apply a polyvinyl alcohol (PVA) separator to the cathode. Power densities were unaffected by the PVA separator (339±29mW/m(2)), compared to a control lacking a separator in a low conductivity solution (1m...
A numerical analysis of the turbulent and strongly swirling flow field of a uniflow cyclone and its performances is described. The gas flow is obtained by the use of the Reynolds stress model while, the determination of particle flow is ensured by the use of a Stochastic Lagrangian model. The flow features are examined in terms of tangential, axial and radial velocities, pressure drop and separ...
Decay studies of very neutron-deficient nuclei ranging from 39 Ti to 49 Ni have been performed during a projectile fragmentation experiment at the GANIL/LISE3 separator. 49 Ni, half-lives and decay spectra have been measured. In a few cases, γ coincidence measurements helped to successfully identify the initial and final states of transitions. In these cases, partial decay scheme are proposed. ...
The combination of HPLC and mass spectrometry has great promise for the toxicology laboratory. In the past five years, significant progress has been made toward producing a reliable interface for these techniques. Thermospray, liquid ion evaporation, ion-spray, and the particle beam separator are all viable "second generation" approaches with significant advantages and disadvantages. I review t...
