Nitrofreeze Cryogenic Solutions Dry Ice Blasts for Historic Restorations

By Ryan Taylor, Nitrofreeze Cryogenic Solutions Dry ice blasting is used in a wide range of historic restoration projects, including a recent one completed in Rockport, Mass., in July of this year. Nitrofreeze Cryogenic Solutions was contracted to dry ice blast barn board wood inside a fishing hut to lighten...

Zero-Loss Liquid Hydrogen Storage and Transfer Technology Transforms the Hydrogen Economy

By Greg Gosnell, CEO of GenH2 Corp. Hydrogen is essential to reducing carbon emissions and transitioning away from fossil fuels. Yet storage and transfer losses of up to 40% have limited its cost-effectiveness and slowed adoption. The key to unlocking hydrogen’s potential lies in Zero-Loss Controlled Storage Technology. By minimizing...

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...

Cryobiology

Andreas Sputtek Past President Society for Cryobiology sputtek@uke.uni-hamburg.de or http://www.sputtek.de/. The word cryobiology (from the Greek words “cryo” = cold, “bios” = life, and “logos” = science) literally signifies the science of life at low temperatures. In practice, this field comprises the study of any biological material or system (e.g.,...

Cryogenic Insulation

James E. Fesmire Cryogenics Test Laboratory NASA Kennedy Space Center james.e.fesmire@nasa.gov Introduction In today’s world, the use of cryogenics and low-temperature refrigeration is taking a more and more significant role. From the food industry, transportation, energy, and medical applications to the Space Shuttle, cryogenic liquids must be stored, handled, and...
