Efficient Helium Separation Of Graphitic Carbon Nitride Membrane

An efficient membrane for helium separation from natural gas is quite crucial for cryogenic industries. However, most experimentally available membranes fail in separating helium from small molecules in natural gas, such as H2, as well as in 3He/4He isotopes separation. … Continue reading

The Unbearable Lightness Of Helium May Not Be Such A Problem After All

Helium gas – essential for MRI scanners, semiconductor manufacture (and according to some, party balloons) – may not be on the verge of running out after all. Previous studies had raised concerns that we were getting close to a world … Continue reading

Metastable Helium

The delightful hue of this low-pressure helium gas is a side-effect of the RF discharge that keeps it in a metastable state. When a handheld Tesla coil is activated in the vicinity of these long, transparent tubes of helium, they … Continue reading

We May Not Be Running Out Of Helium After All

Helium is the second most abundant element in the Universe, but it’s relatively rare on Earth – so much so that some have called for a ban on party balloons to ward off a worldwide shortage. However, a team of … Continue reading

Volcano And Early Warning: Helium Anomaly May Add Knowledge

The 2014 eruption of Mount Ontake in Japan–which resulted in 58 deaths, with 5 people still missing–may have occurred because a helium isotope increased in the 10 years prior to the mountain’s major disruption. In fact, that helium isotope may … Continue reading
