Commonwealth Fusion Systems Signs PPA with Italian Energy Company Eni

By Zachary Skidmore Google-backed nuclear fusion firm Commonwealth Fusion Systems (CFS) has signed a Power Purchase Agreement (PPA) with Italian energy firm Eni for power from its ARC power plant in Chesterfield County, Virginia. In July, CFS became one of the first fusion firms to sign a PPA with a...

New Entanglement Breakthrough Links Cores of Atoms, Brings Quantum Computers Closer

Quantum entanglement — once dismissed by Albert Einstein as “spooky action at a distance” — has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum practitioners, the reality is rather more mundane: entanglement is a kind of connection between particles that is the quintessential feature...

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...

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...

Designing a liquid oxygen bath

I’m designing a Liquid Oxygen Bath to place composite coupons in the bath and soak 96 samples for intervals of 8 hours, 24 hours, 7 days, 21 days, 42 days, 62 days and 90 days.

Metallic Salts Normally Used to Produce Ultra-Low Temperatures?

Regarding the method known as the Adiabatic Demagnetization of Paramagnetic Salts: What metallic salts are normally used to produce the ultra-low temperatures used for near-absolute-zero cryogenic research? Which salts are the most efficient? Which make the best cooling agents? And which are used most commonly by physicists? I am looking...
