zeroBOG™ Empowers Sustainable Operations

by Lennis Perez and Edward Tay, Sulzer The need for efficient and sustainable management of cryogenic gases extends far beyond traditional LNG applications. Enabling the recovery and reuse of boiloff gases, or BOG, across sectors such as hydrogen, e-methane and ammonia, supports the transition to low-carbon fuels and helps operators...

Liquid Air Comes of Age in Manchester

by Mark Vyvyan Robinson, Business Development Director, Highview Power As electricity systems integrate increasing volumes of renewable generation, the requirement for long-duration energy storage has become a defining challenge of the global energy transition. In northwest England, the city of Manchester and the surrounding Greater Manchester region are now home...

NASA Inches Closer to Martian Laser Communication

by Charlie Danaher, Danaher Cryogenics Bridging Interplanetary Distances Having a conversation between someone on Earth and Mars is not as science fiction as it used to be. That is thanks to scientists at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and their successful demonstration of the Deep Space Optical...

Vacuum Chambers Answer Quantum Demands and UHV Transfer Needs

by Mel Janecka, Atlas Technologies Quantum computing companies and research facilities often find aluminum and titanium vacuum chambers to be better equipped to maintain purity and ultrahigh-vacuum (UHV) status. Plus, the chambers are non-magnetic and perform effectively within cryogenic conditions, critical for keeping qubits stable. Qubits, the basic units of...

Kathleen Amm’s Evolution in Cryo

When Kathleen Amm describes how she entered cryogenics, she does not point to a single defining moment. Instead, her path began with movement. In the early 1990s, she followed her thesis advisor Justin Schwartz from the University of Illinois to Tallahassee as the National High Magnetic Field Laboratory was opening....

WOMEN in CRYOGENICS and SUPERCONDUCTIVITY

Alexandria Burger, Bluefors – Manufacturing Engineer Manager Current projects: My current focus is leading a team to improve manufacturing efficiencies for 2026. These efficiency improvements will not only offset the increasing costs of materials but also allow us to reduce lead times. I also contribute to manufacturing documentation, 6S events,...

Two-Phase Flows

Two-phase flows are those flows in which there is a mixture of two physical states (solid, liquid or vapor). In cryogenic applications, such flows are almost always a mixture of a cryogenic liquid along with its corresponding vapor. A mixture of liquid helium and helium vapor would be a typical...

Supercritical Fluids

A supercritical fluid is defined as a substance whose temperature and pressure exceed those of its critical point. Every pure substance has a critical point that is defined in thermodynamic space by a critical temperature and a corresponding critical pressure. For example, the critical point for helium has a critical...

Brayton Cycle

The Brayton cycle is one of the many thermodynamic cycles used to generate cooling at cryogenic temperatures. Strictly speaking, when referring to cooling we should call this the reverse Brayton cycle as the original Brayton cycle describes the process of power generation or propulsion via a gas turbine. In many...

Air Separation and Liquefaction

by Nils Tellier, PE, President, EPSIM Corporation (CSA CSM) nils@epsim.us All illustrations courtesy EPSIM Corporation Background History of Air Separation and Liquefaction This section builds on a rich history of methods to develop deep refrigeration and cryogenic liquefaction during the 19th Century. 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...

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...

Thermal conductivity of niobium, tantalum, lead, tin

I am interested in the thermal conductivity and other properties of low temperature superconductors. Specifically I am interested in materials like Niobium, Tantalum, Lead and Tin. Would you know of a publication that dealt with thermal properties in general and also gave specific data on these materials?
