whereas that of Sm2Co17magnets ranges from 80 to 240 kJ/m3. The size of the Sm–Co magnet industry worldwide was approximately 1400 tons of alloy in 2014 [33]. Sm–Co magnets are relatively expensive and subject to price fluctuations because the cobalt market is very price...
Everledger described its solution to trace and document the origin of diamonds, and how this can help ensure sustainable practices throughout the 3TGs and cobalt trade (through promising technologies including “bar codes” such as fingerprinting, dust environment monitoring, isotopes, spectrographic ...
There are only a limited number of electrolytes that show reversible Mg plating/stripping; but many of these electrolytes contain volatile solvents such as tetrahydrofuran (THF)13,15,16 or dimethoxyethane (DME)17. Electrolytes based on less volatile or nonvolatile solvents are desired31,32. More ...
