The paper draws attention to three commercial forms of cathode-ray oscillograph which may be employed in the study of very high-frequency alternating or impulsive electrical phenomena.The behaviour of a stream of cathode rays in electrostatic and magnetic fields is first dealt with, and the penetrating power of cathode rays through matter is considered

Layered Li-rich oxides (LROs) that exhibit anionic and cationic redox are extensively studied due to their high energy storage capacities. However, voltage hysteresis, which reduces the energy conversion efficiency of the battery, is a critical ...

Effect of Eliminating Water in Prussian Blue Cathode for Sodium‐Ion Batteries
Advanced Functional Materials, 2022Prussian blue analogs (PBAs) are promising cathode materials for sodium‐ion batteries (SIBs) due to their low‐cost, similar energy density comparable with that of LiFePO4 in lithium‐ion batteries, and long cycle life. Nevertheless, crystal water (≈10 wt%)

Rhombohedral prussian white as cathode for rechargeable sodium-ion batteries.
Journal of the American Chemical Society, 2015A novel air-stable sodium iron hexacyanoferrate (R-Na1.92Fe[Fe(CN)6]) with rhombohedral structure is demonstrated to be a scalable, low-cost cathode material for sodium-ion batteries exhibiting high capacity, long cycle life, and good rate capability ...

Cathode-Ray Presentation of Chromatograms [PDF]
Nature, 1960 FROM the results of investigations on nylon capillary columns1, it became apparent that there were two possible applications for the capillary system. The columns could be used to produce very high efficiencies with elution times of 10–60 min., or the high efficiencies could be sacrificed and chromatograms developed in a matter of seconds, with ...

Devices in which phosphors are excited by means of cathode rays have great practical importance: cathode-ray tubes are used for television, oscilloscopes, electron microscopes, etc. Cathode rays are a beam of fast electrons; the accelerating voltage in a television picture tube is high (> 10 kV).

Radioactivity in cathode ray tubes
Health Physics, 2004While surveying used computer equipment out of a zone posted as a Contamination Area, 100% of the computer monitors surveyed had levels of radioactivity that were significantly above background. The radioactivity was primarily on the front face of the cathode ray tube and was not amenable to decontamination.

The modern cathode-ray oscilloscope is designed as a measuring instrument, and is the most useful of all electronic test devices. So great is its versatility that workers in every branch of scientific activity now find the instrument to be almost indispensable.

The study of the passage of electricity through gases had lagged behind the corresponding study on metals and liquids. Faraday himself had engaged in research on electrical discharges in gases as early as 1838 but was hampered by the inefficiency of his vacuum pumps.
