Coercivity Improvement in Ce‐Containing (Nd,Pr)‐Fe‐B‐Based Sintered Magnets by Application of the 2‐Powder Method

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the magnetic properties and microstructures of 2PM‐manufactured Ce‐containing (Nd,Pr)‐Fe‐B magnets. The addition of Nd and Dy significantly enhances coercivity by 25% and 81%, respectively, attributed to core‐shell structures.

Interfacial tension and hydrogen-ion concentration [PDF]

open access: yesProceedings of the Royal Society of London. Series B, Containing Papers of a Biological Character, 1931
(1) Long chain carboxylic acids dissolved in benzene show regular changes in interfacial tension against aqueous "buffered" solutions as the hydrion concentration of these is altered. A fall in interfacial tension starts at p h 5·5 and extends over the range of 4·0 p h
