Abstract: Active magnetic regenerative (AMR) refrigeration is expected to be used for hydrogen liquefaction owing to its wide operating temperature range. In a previous study, a reciprocating type of ...

The scientists thus innovated on an alternative method using magnetic refrigeration and magnetocaloric materials. The method involves transferring heat from the materials to a heat sink via strategic ...

It’s a ramp-up from last July, when China placed restrictions on gallium and germanium exports after enduring years of ...
