Bluefors Joins Chicago Quantum Exchange

Bluefors has joined the Chicago Quantum Exchange, strengthening CQE’s Midwest roots as the region expands efforts to build a quantum supply chain, expand innovation capacity, and scale a quantum workforce. Bluefors plays a vital role in all three areas. We opened our first US-based Bluefors Lab in Chicago last year,...

NASA Set to Test Orbital ‘Gas Station’ Technology to Propel Moon and Mars Missions

NASA’s LOXSAT mission aims to test orbital fuel transfer, potentially turning spacecraft into “gas stations in space” for lunar and Mars missions. A groundbreaking NASA mission could soon transform how astronauts travel to the moon and beyond. The upcoming Liquid Oxygen Flight Demonstration (LOXSAT) will test critical technologies for storing...

AI has a power delivery problem. Superconductivity offers a path forward

AI is changing what power delivery must do, and new approaches are required Growing AI energy demand is not only forcing data centers to address generation challenges, but also how power is delivered. As power density rises and timelines tighten, high-temperature superconductors (HTS, also known simply as superconductors) are moving...

Molecular Qubit Achieves Single-Photon Quantum Control

A team of researchers report a single organic molecule can now store, manipulate and read out quantum information one molecule at a time using light. They add that their work hints at a possible new quantum modality built from chemically engineered molecules rather than fabricated semiconductor defects. The study, published...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. You are encouraged to read Cryo Central’s History...

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...

Assistance with resolving a sealing problem?

We are fabricating piping components for refrigeration service. These components must be leak checked at 15 bar (218 psig). We are using a gas test media that is 25% helium and experiencing difficulty on maintaining a seal on the flanged connections. Do you know anyone or any references that could...

Cryogenic data on leather and nomex

Could anyone please help me out with the following cryogenics data: Leather — mechanical properties at 77 K or lower Nomex — thermal conductivity @ 4 to 50 K I lost the data I had some time ago and although this should be easily accessible, I can’t find any reference...
