Goodwill Cryogenics Releases Cryo-Founders Calendar

This month, India’s Goodwill Cryogenics produced and shipped the first-ever “Cryo-Founders Calendar.” Dr. Vinod Chopra, Goodwill’s founder, designed it as a tribute to 12 legends of cryogenics. Each month features a different leader in the field of cryogenics with a short bio and list of notable achievements. Included in this...

Pakistan’s First Private LNG Shipment Expected by December

Pakistan’s first private LNG shipment, comprising approximately 130,000 cubic meters, is scheduled to arrive at Karachi by the end of November, according to Ghiyas Abdullah Paracha, chief executive officer of Universal Gas Distribution Company. He stated that he appreciated the government’s approval for the private sector to import LNG and...

LCWS Participants Publish ‘Sendai Statement’ in Support of the International Linear Collider

Scientists gathering in Sendai, Japan, for a scientific conference about a possible future particle physics project to lead the next generation of research following the Large Hadron Collider at CERN in Geneva reaffirmed their commitment to engage in the construction and scientific exploitation of the International Linear Collider as a...

New Payload Fairing from RUAG Space Enables Quieter Journey to Space

RUAG Space (CSA CSM) has successfully developed and tested a new, low shock jettison system funded by the Future Launchers Preparatory Program (FLPP) of the European Space Agency (ESA). The program develops technologies for future European launch vehicles and upgrades of existing launch vehicles. This system enables a quieter and...

LN2 Freezing of Live Bacteria in Dairy Products Boosts Productivity, Lowers Costs

GEA, an Australian electrical component company, has now launched a nitrogen freezing pilot plant for bacteria which takes a novel approach: freezing the bacteria in droplets using a liquid nitrogen bath outside the freeze dryer, then drying the pellets via the normal procedure. By freezing bacteria into pellets before drying,...

Thales Cryogenics, Eindhoven Receives NASA Awards

NASA has awarded the cryogenics department at Thales, Eindhoven two recognitions at its 2019 Honors ceremony held at the Jet Propulsion Laboratory in Pasadena the week of November 11. Both were awarded for Thales’ contribution to the success of the ongoing ECOSTRESS mission. The group received the NASA Group Achievement...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
