Helium is valued as a gas for lifting, breathing, leak detection, shielding, its inert properties and as a liquid for cooling. Many industries can benefit from its unique properties to optimize performance and productivity, reduce labor costs, and make operations safer.
Jul 24, 2008· This month has seen the centenary of the first liquefaction of helium, the lightest noble gas: On July 10, 1908, a complicated apparatus working in the laboratory of Heike Kamerlingh Onnes in Leiden, Holland, managed to produce 60 ml of liquid helium, at a temperature of Kelvin, or −269°C.
Using liquid helium, Kurti, coworkers and others have succeeded in obtaining temperatures of a few microkelvins by the adiabatic demagnetization of copper nuclei. Helium has other peculiar properties: It is the only liquid that cannot be solidified by lowering the temperature.
Liquid helium is inherently extremely pure — far more pure than even Grade 5 helium actually, and liquid is the most efficient way to move product. Therefore, for helium suppliers to purposely offer a lower grade helium, they would actually have to add new operational methods and separate processes and transport specifically geared for the lower purities.
degassing, the sample was exposed to nitrogen gas at liquid nitrogen temperature ( oC) at a series of precisely controlled pressures. Free space (dead volume of the tube) determination was done by volumetrically using helium before measurement of adsorption isotherm.
Hence, the normal crusher which was used to reclaim materials, such as waste tires, nylon, plastic and many polymer materials at atmospheric 12 temperature is being replaced by a cryogenic crusher. • In the cryogenic crusher, the property of the milled material is usually very sensitive to temperature change.

Sep 11, 2014· Introduction to Liquid Helium in Space, Part 1 Helium in Space SHOOT Superfluid Helium OnOrbit Transfer. The Cryogenics Fluids Branch has developed a practical application the fountain effect, a superfluid helium pump. After testing on the ground, the pump flew in the space shuttle as the Superfluid Helium On Orbit Transfer (SHOOT) project.
Helium Flotation How Helium Balloons Work | HowStuffWorks. The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air.
