Cold Facts Digital – The go-to place for Cryogenics and Superconductivity

New Superconductor Could Lead to Quantum Computing Breakthrough

Superconductivity is the property of zero electrical resistance at ultralow temperatures and was discovered in 1911 by the Dutch physicist Kamerling-Ohnes. It plays a crucial role in many industries and technologies, ranging from quantum computing to energy. “Superconductors are amazing materials which have many strange and unusual properties,” explained Joe Carroll,...

Cryogenic SRAM IP Demonstrator Taped Out

sureCore’s cryogenic SRAM is a building block for any digital sub-system, that is capable of operating from 77K (-196° C) down to the near absolute zero temperatures needed by Quantum Computers (QCs). Standard cell and IO cell libraries have been re-characterized for operation at cryogenic temperatures, thereby enabling an industry...

New Bolometer Could Lead to Better Cryogenic Quantum Technologies

A new type of bolometer that covers a broad range of microwave frequencies has been created by researchers in Finland. The work builds on previous research by the team, and the new technique could potentially characterize background noise sources and thereby help to improve the cryogenic environments necessary for quantum...

Success in Harsh Environments: Signaling the Future of Cryogenic Communications

XMA, with its space heritage spanning from low-Earth orbit (LEO) to deep space exploration units, embarked on a journey to enter the supply chain for quantum computing more than 10 years ago. The driving force behind this industry expansion was XMA’s success in cryogenic temperatures down to approximately 4 K...

Air Gases Can Benefit the Environment

Overview-The commercial production of oxygen and nitrogen supported the industrial revolution in the late 19th century and up to the mid-20th. Oxy-acetylene cutting and welding were important for projects like the Eiffel Tower, the Panama Canal and the Central Valley Project Corporation hydropower plants. Oxygen, nitrogen and argon refined steelmaking...

Analyzing Transcritical CO2 Compression and Pumping Pathways

Supercritical carbon dioxide exhibits anomalous behavior in the vicinity above the critical point. The Irish physical chemist Thomas Andrews (1863) was the first who studied the supercritical behavior of carbon dioxide. He explained his observations of the fluid state above the critical point as follows: “…the surface of demarcation between the...

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...

Definition or max temp which defines “cryogenic”?

Please help me with a definition: I am calculating material and fabrication costs for a quote for a hydrocarbon meter station.

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?

Data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K.

I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
