Entropy-Tailored Fast-Charging Sodium Layered Cathodes

Journal of the American Chemical Society
O3-type layered transition metal (TM) oxides are widely used as cathode materials for Na-ion batteries due to their high energy density potential, enabled by the state of charge (SoC)-dependent transition from octahedral (O-type) to prismatic (P-type) structures during Na-ion (de)sodiation.

Cathodic hydrogen charging and mechanical properties of copper

Journal of Materials Science, 1994
The influence of cathodic hydrogen charging on some mechanical properties of copper was studied. Hydrogen charging was found to decrease both the ultimate tensile strength and the failure strain of copper. The surface layers of copper were hardened, but they recovered to their prior hardness with time passed after hydrogen charging.

Distribution of Cathode Charge in a Multiwire Proportional Chamber

IEEE Transactions on Nuclear Science, 1984
Detailed measurements have been made of the lateral distribution of induced charge on wire cathodes in a multiwire proportional chamber. The results are in close agreement with the predictions of a theoretical model in which the effect of ground planes behind the cathodes, avalanche angular localisation, and signal processing are included.

Effect of cathodic charging on the mechanical properties of aluminum

Metallurgical Transactions A, 1988
The effects of cathodically charged hydrogen on the mechanical properties of pure aluminum have been studied through the use of tensile and microhardness tests. The effects have been further examined with TEM observations of the microstructural changes that accompanied the charging.

Peculiarity of hydrogen distribution in steel by cathodic charging

Journal of Alloys and Compounds, 2003
Steel surfaces of machines undergo corrosion protection most commonly by means of electrodeposited Zn, Cd, Ni, Cr etc. with chemical or electrochemical surface pretreatment for deposition. To preserve the surface geometry steel wire and strips undergo cathodic electrocleaning in an alkaline bath and cathodic etching or pickling in acid solutions.

Defects Induced in Copper by Cathodic Charging of Hydrogen

Journal of The Electrochemical Society, 1989
Scanning and transmission electron microscopes were used to study the effect of cathodic charging of hydrogen on the defect structure of bulk copper foils. Cathodic charging of hydrogen over an extended period of time (~24h) resulted in a considerable reduction in the ductility of copper foils.

Space-charge waves in a double-cathode tube

Proceedings of the IEEE, 1972
A double-cathode tube is working in the space-charge region. A small-signal theory for such a tube, including transit-time effects, yields the result that two space-charge waves are traveling inwards from each of the cathodes.

Cathode charge sampling readout system for MWPC

Nuclear Instruments and Methods in Physics Research, 1983
Abstract In order to reach a horizontal spatial resolution of about 0.1 mm in the two arms spectrometer of the CERN UA-6 experiment, it is planned to add to the MWPC an induced charge cathode readout system. The construction of the chambers and the cathode readout electronics are described. Results of preliminary tests are given.

Charge localization on the surfaces of oxide-coated cathodes

British Journal of Applied Physics, 1960
Anomalous results obtained while using the Kelvin method of determining contact potential differences between oxide-coated cathodes and an evaporated gold film reference surface in an atmosphere of hydrogen have been investigated. Very high contact potential differences have been associated with a separation of charge from ionized gas on the passage of
