Bluefors is delighted to announce that Greg Parker has become President, Cryocoolers, effective August 3. In his new role, Greg will lead the Cryocoolers business based in Syracuse, New York, and become a member of the Bluefors Group Leadership Team. He succeeds Rich Dausman, who has decided to retire after...

The Hidden Giants of Industry: How Heat Exchangers Quietly Power Almost Everything You Use

Headlines are not sought after, records are not broken, nor are they going viral, but they are among the most important machines in the modern world: heat exchangers. Even if it’s in massive oil refineries, skyscrapers, industrial food manufacturing, or massive data center operations, these technologies move tremendous amounts of...

Cold Radioactive Molecules Offer a Tabletop Route to New Physics

A new method of stabilizing radioactive molecules could open the door to sensitive searches for physics beyond the Standard Model. The approach, which involves cooling radium-bearing molecules to just above absolute zero, offers a tabletop alternative to experiments that use particle accelerators to look for violations of fundamental symmetries. According...

Hydrogen: Clean Fuel of the Future—If We Can Find a Cheap and Clean Way to Ship It

Many experts refer to hydrogen as “the fuel of the future.” It is expected to help decarbonize the global economy in two main ways: Burning it or feeding it into a fuel cell produces storable energy with no carbon emissions, just water. It can also be used in place of...

SEALSQ and GlobalFoundries Partner on Post-Quantum Security

SEALSQ Corp (Nasdaq: LAES) (“SEALSQ“) and GlobalFoundries (Nasdaq: GFS) (GF) recently announced a strategic Memorandum of Understanding (MoU) to co-develop across secure semiconductor platforms, Post-Quantum Cryptography (PQC) and emerging semiconductor-based quantum computing technologies. The partnership leverages GF’s process technology leadership and manufacturing capabilities alongside SEALSQ’s expertise in hardware-based certified security,...

H2-Aero Symposium: An Industry-Academia-Government Push to Decarbonize Aviation and Airports with Hydrogen

Hydrogen offers a great potential to commercialize zero emission aviation and fuel, using up to ~1/3 less energy and having lower costs at scale to produce than SAF. The symposium highlighted the latest advances in hydrogen aerospace and liquid hydrogen. Left unabated, Aviation is projected to emit over 20% of...

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...

Scottish Researchers Develop 100kW Superconducting Motor for Aircraft

Scottish researchers have demonstrated a 100kW superconducting motor that could pave the way for future electric aircraft. The prototype, created in the Applied Superconductivity Laboratory (ASL) of the University of Strathclyde in Glasgow, is one of the first attempts in the world to develop a fully superconducting axial-flux motor for...

Air Separation and Liquefaction

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...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
