When cooled, it only condenses into a liquid at the stunningly low temperature of roughly 4.2 Kelvin, or -269C/-452F. Plus, under normal atmospheric conditions, helium will not freeze even at ...

since it does not account for the gradual 'freezing in' of the Debye frequencies. According to our conception the quantum states of liquid helium would have to correspond, so to speak, to both the ...

“The applications, they’re a little bit sexier than filling party balloons. Liquid helium is the coldest substance on the planet and it’s used as the refrigerant for the super-conducting ...

It took some detective work, but they think they know what was the cause. The MRI machine uses liquid helium to cool its powerful magnets. Turns out the helium had leaked and over 5 hours about ...

To keep their molecular hydrogen liquid below its freezing point, team leader Takamasa Momose and colleagues at UBC confined small clusters of hydrogen molecules inside helium nanodroplets at 0.4 K.
