Indian Student to Research Liquid Hydrogen with Monash University

A Ph.D. student from India is conducting groundbreaking research with Monash University’s Department of Civil Engineering after being selected as the recipient of the prestigious Australian government-funded Maitri Scholars Program. Chennai native Rohith Prakash will focus on advancing the safe transport and storage of liquid hydrogen, with a particular emphasis on...

Rising Helium Demand Set to Double by 2035

A new report from IDTechEx suggests that global helium demand is set to double by 2035, driven by the wide-ranging applications of this vital element. Helium, a finite yet critical resource, is indispensable across multiple industries. From medical imaging to semiconductor manufacturing, helium’s unique properties—such as high thermal conductivity, chemical...

Cryogenic Therapy Puts the Freeze on Esophageal Cancer

Patients with esophageal tumors often experience malignant dysphagia, or difficulty swallowing due to an obstruction, complicating their treatment and preventing them from eating normally. The Advanced Center for Therapeutic Endoscopy at WVU Medicine J.W. Ruby Memorial Hospital is the first in West Virginia to offer an innovative solution to this...

First Modern Liquid Oxygen Manufacturing Plant To Be Constructed At Tatu Industrial Park

Hewatele, a company based in Kenya that focuses on providing medical-grade oxygen and other healthcare solutions, held a groundbreaking ceremony for the construction of East Africa’s first modern liquid oxygen manufacturing plant, designed to address the rising demand for medical-grade liquid oxygen in healthcare facilities throughout the region. The advanced cryogenic medical...

Superconductor Offers Possible Room-Temperature Bridge

A new superconducting compound offers a bridge to more practical superconductors with a potentially attractive range of applications, according to new research. And the new material’s strange magnetic behavior recalls classic superconductors of decades ago—but this time in a material that’s already demonstrated its near-room-temperature bona fides. Lanthanum hydrides—which combine atoms of the...

Latest in Defining Cryogenics

Refrigerators and Liquefiers

Two of the most common terms used in cryogenics are “refrigerator” and “liquefier.” These terms describe similar and, as will be seen, in some cases identical components. A refrigerator provides cooling (that is, absorbs heat) at cryogenic temperatures. Refrigerators typically put a working fluid (such as helium) through one of...

Air Separation

Air separation is one of the largest, as well as earliest, industrial applications of cryogenics. In this process, cryogenic temperatures are used to separate air into its constituent gases: nitrogen (78.08%), oxygen (20.95%), argon (0.93%) and carbon dioxide (0.3%). Trace gases such as krypton, neon, xenon and helium total far...

Coefficient of Performance and Figure of Merit

The coefficient of performance (COP) is used to describe the effectiveness of refrigerators, including those operating at cryogenic temperatures. The COP is defined as the amount of heat removed at the cryogenic operating temperature of the refrigerator divided by the amount of work that must be applied to remove the...

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...

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?
