DOE Announces $25 Million to Develop Next Gen Electric Machines for Industrial Energy Savings

The Department of Energy (DOE) on March 11 announced $25 million in funding aimed at advancing technologies for energy-efficient electric motors through applied R&D. The DOE intends to select eight to twelve projects that leverage recent technical advancements in nanomaterials research, high temperature superconductivity, magnet development and deployment of lead-free,...

NASA Glenn Invites the Public To Go Behind-The-Scenes

NASA’s Glenn Research Center in Cleveland will open its doors once a month beginning April 2 for a behind-the-scenes, one-hour guided tour of one of its world-class research facilities. Glenn tours, held through October, are part of NASA Glenn's 75th Anniversary. Two open house opportunities at Lewis Field in Cleveland...

Preserving the Innocents: Biosample Storage at -190°C

by Julian Warhurst, julian.warhurst@brooks.com; John Fink, john.fink@brooks.com; Tiffany Holmes, tiffany.holmes@brooks.com; Matthew Albert, matthew.albert@brooks.com; Bruce Zandi, bruce.zandi@brooks.com It seems to be universally accepted that storing at -190°C in a liquid nitrogen (LN2 )vapor-phase freezer is the best technique for biosample preservation. Brooks Automation (CSA CSM) decided to explore this idea further,...

Scientists Prep for DUNE Neutrino Study

Over 150 physicists from around the world collided at The University of Texas at Arlington in early January to further collaboration on DUNE, the Deep Underground Neutrino Experiment. The international project, scheduled for completion in the early 2020s, will shoot a neutrino beam from Fermi National Accelerator Laboratory (CSA CSM)...

Superconducting Radio Frequency Activities at CERN

CERN has a long history in superconducting radio frequency (SRF) technology. What started with a few SRF cavities in the 1980s has now become a major field of activity. Today CERN is not only running a variety of superconducting RF installations and projects but is also preparing for a new...

Next Generation Multilayer Insulation with Discrete Spacer Technology, Parts 1 and 2

Cryogenic thermal engineers are familiar with multilayer insulation (MLI), developed in the late 1950s as lightweight insulation for cryogenic propellants. MLI is used as high performance thermal insulation for launch vehicles, spacecraft, cryogenic tanks, dewars and spaceborne instruments. MLI operates in high vacuum, where its performance exceeds other insulations by...

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...

Cryogenic Finishing

The following 3 articles discuss the uses and procedures of various type of cryogenic finishing. 1) By Robin A. 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...

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....
