Helium II
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate
A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...
Cold Technology for Pest Control
While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...

Rhodes, Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Cryogenic Deflashing is employed to remove undesired residual mold flash that remains on molded parts after they are removed or ejected from the...
Seeking technical publication that explains the science behind the cryogenic treatment of aluminum
Would you know of a technical publication that would list the benefits and explain the science behind the cryogenic treatment of aluminum, specifically a 356-T6 aluminum cylinder head casting? Eddie Phillips
Source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K
Can anyone recommend a source of emissivity data for aluminum and aluminized Mylar at room temperature, 77K and 4.2K? Also, I would be interested in finding a facility that can measure this information. Any information will be greatly appreciated. William Einziger, GE Healthcare
Looking to purchase new LN2 freezer: any suggestions?
I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...
Affordable flow meter to measure LN2 flow through a pipeline
I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
