Ratermann Keeps Valves and Industry Confidence Flowing

By Jocelyn Navarro, Ratermann Manufacturing For companies working with cryogenic and industrial gas systems, valve failure isn’t just a maintenance issue; it’s a safety risk. Pressure relief valves must operate with precision under intense thermal and mechanical stress. That’s why Ratermann Manufacturing has made valve recertification a central part of...

Lake Shore Reduces Helium Costs to Maximize Research Efficiency

By Rachael Floyd, Director of Product Management for Cryogenic Systems, Lake Shore Cryotronics The Rising Price of Helium Helium is a nonrenewable resource that is increasingly difficult to obtain reliably. Once released into the atmosphere, it is irretrievable. Limited availability and few sources of production are driving helium prices upward....

Cryo-EM at University of Cincinnati Reveals the Invisible and Transforms Structural Biology

By Megan Burgasser For the first time, researchers at the University of Cincinnati have visualized the structure of two key protein partners involved in inflammation and immune signaling. This breakthrough—published in the Proceedings of the National Academy of Sciences—not only uncovers the structure of the ADAM17 enzyme in complex with...

Tiny Cryogenic Device Cuts Quantum Computer Heat Emissions By 10,000 Times

Researchers have developed a tiny device that extinguishes one of the biggest heat sources in quantum computers, cutting their running costs and potentially bringing these machines closer to commercial reality. Most quantum computers operate at temperatures close to absolute zero (459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) using specialized cooling equipment to...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

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...
