NASA to send up teachers on SOFIA

NASA has selected six teachers to work with scientists aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA) during research flights in May and June. This is the first team of educators selected to participate in SOFIA’s Airborne Astronomy Ambassadors program.

LBNE Takes a “Hive’s Worth” of Experts

In the May symmetry, in an article titled, “LBNE: the inside buzz on a new science project,” Amelia Williamson Smith reports that planning and designing the $900 million Long Baseline Neutrino Experiment takes more than a village. It takes a hive’s worth of scientists, engineers, technicians, accountants, and other specialists...

More than 15,000 attend Goddard Open House

NASA’s Goddard Space Flight Center in Greenbelt MD hosted more than 15,000 visitors under gray but rain-free skies on May 14. The Explore@NASA Goddard event was the center’s first open house since 2008, according to Robert Garner of the Center.

Berkeley Lab Researcher Wins DOE Early Career Award

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...

Seeking alloy that keeps elastic property down to 10K

I am looking for a metal (alloy) that supports high temperatures (at least 1600K) and keeps its elastic property at low temperatures down to 10K. Rhenium is a good one because it does not become brittle. But it is quite expensive. Pure tungsten and molybdenum enter in the brittle regime...

Searching for a freezer that does not need electricity

I’m student of University of Barcelona. We do technical cryogenic research and we are searching for a cryogenic portable freezer that does not need electricity. We can’t find any company that offers something like this. The product we are looking for is the typical portable freezer for food or drinks...

FEP Encapsulated O rings in the cryogenic process

Can you please advise if FEP Encapsulated O rings are used within the cryogenic process and what materials? I have been asked by my company to write about FEP Encapsulated O rings for a training seminar.

Need material property data for polycrystalline / sintered ceramics

I am a ME grad student currently working on the design of a detector array / focal plate of a scientific space instrument operating at a temperature of about -80…-100°C. Although this is not in the cryogenic temperature range, I would like to address two questions to you as the...
