High Pressure Milling Vial – evico magnetics

It involves high-energy ball milling in an especially designed vial, allowing in-situ monitoring of temperature and, more importantly, of hydrogen pressure by incorporating a newly developed gas-temperature measurement system as well as a radio emitter into the vial lid. An external receiver transmits the data to a data acquisition computer.
