Because it is chemically inert, it is also used as a gas shield in robotic arc welding and as a non-reactive atmosphere for growing silicon and germanium crystals used to make electronic semiconductor devices. Liquid helium is often used to provide the extremely low temperatures required in ...

Today, there is a critical shortage of helium-3, regular heliums lighter, more elusive cousin. The supply crunch was probably inevitable. The crisis, however, was entirely man-made, and somebody should have noticed before the red light came on.HENRY TERRELL...

A basic hologram is easier to setup than you might think. HowStuffWorks It doesn't take very many tools to make a hologram. You can make one with: A laser: Red lasers, usually helium-neon (HeNe) lasers, are common in holography. Some home holography experiments rely on the diodes fro...
His theory was inspired by the less common isotope of helium, namely 3He4, the first experimental platform for testing the theory. Decades later, the theory was also applied to strongly correlated metals, known as heavy-fermion systems5. Leggett, reviewing liquid 3He6, writes that it is “...

Step 2: Add a Helium miner The next step is to find out the plus (+) symbol to add a Helium miner, for example, the RAK Hotspot Miner, to the app. The chosen miner needs to be plugged in to operate, and a tiny red light will confirm that it is working. Then, a button on th...
