There and Back Again-The Journey of LiNiO2 as a Cathode Active Material.
Angewandte Chemie, 2019This Review provides a comprehensive overview of LiNiO2 (LNO), almost 30 years after its introduction as a cathode active material. We aim to highlight the physicochemical peculiarities that make LNO a complex material in every aspect.

Improved Sofc Cathodes and Cathode Contact Layers
2008SOFC development at Forschungszentrum Julich is aiming at high power density and high durability to achieve cost reduction in manufacturing and installation. For higher power density the work on materials development has been focused on improving the cathode performance by modification of the component thickness, the microstructure and the choice of ...

Cathode and Anode Optimization in a Virtual Cathode Oscillator
IEEE Transactions on Dielectrics and Electrical Insulation, 2007We are fabricating and testing several different types of cathodes for the same vircator driven by a single shot Marx generator and pulse forming line (300 kV, 60 ns, 30 Omega). The cathodes types, each with an emitting area of ~32 cm2, include the original velvet with a new geometry, carbon fiber, pin-array, and an array of all metal cathodes.

Publisher Summary This chapter discusses the cathode used in a solid oxide fuel cell (SOFC). The cathode possesses sufficient electronic conductivity to support electron flow in the oxidizing environment at the operating temperature. In general, maximum possible cathode conductivity is desirable to minimize ohmic losses.

Dependence of cathode aperture in pulsed hollow-cathode discharges
Applied Physics Letters, 1992The effect of electric field penetration in the hollow-cathode region of self-initiated pulsed hollow-cathode discharge is investigated. The discharge is operated in hydrogen at pressures between 30 and 200 mTorr with applied voltages between 10 and 30 kV.

The Hopping Electron Cathode for Cathode Ray Tubes
2004Publisher Summary The hopping electron cathode (HEC) is a novel low-drive electron source that can be used in cathode ray tubes (CRTs) to reduce the cost of the set electronics and to improve the image quality. It is based on a self-regulating secondary emission process enabling transport of electrons over insulating structures.

Collisionless instability of the cathode sheath in a hollow-cathode discharge
Physical Review Letters, 1993High-intensity periodic variations of the potential fall across the cathode sheath are observed in a low-pressure magnetic-field-free hollow-cathode discharge. These potential variations cause modulation of the discharge current, reaching a depth of almost 100%.

The cathode ray oscillograph, since its invention by Braun, has developed along three lines. The major types of tubes are the high voltage tubes with a fluorescent screen, the high voltage tubes with internal photographic equipment, and the low voltage tubes. This paper follows the structural development of commercial tubes.
