Cryogenics Impacts Life Sciences

“It’s too hot, it’s too cold.” We have all heard those famous words from family, friends, coworkers or feedback from instrumentation. Whether it is to control temperature in a confined environment, rotating equipment, or bioprocessing, cryogens are utilized throughout industries.  At times, valves are overlooked as an integral part of...

Ovarian Tissue Cryopreservation Offers Hope in Canada

A monumental program centered on ovarian tissue cryopreservation is offering hope to women and girls across Canada. Dr. James Benson, a world-renowned cryobiology expert, leads this transformative initiative. This medical procedure safeguards healthy ovarian tissue before cancer treatments can harm it, ultimately enabling female patients to have biological children in...

Why Are Quantum Technologies So Cool?

Efforts to build a useful quantum computer are underway, with startup companies competing alongside the big leaders in information technology. Other quantum technologies are already part of our everyday lives, from MRI scanners in hospitals to atomic clocks, which are used to keep precise track of time on GPS satellites...

Nanoparticles Show Quick and Easy Way to Target Cancer

Researchers have been exploring the use of injectable nanoparticles that can quickly home in on a microscopic tumor. It’s a novel technique that could pave the way for the early detection of small tumors that may not show up on traditional imaging technologies. In a study published in the October issue of...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

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...
