Techno-Economics of Liquid Hydrogen Supply for Australian Antarctic Operations

Antarctic research productivity relies on consistent access to energy. Increased availability of cheaper and cleaner energy could enhance the research capacity at Antarctic stations and expand the frequency of research flights using aircraft such as the Basler BT-67 (a modified DC3) to map climate change impacts on glaciers. The Australian...

Meet the 2025 Young Professionals

Qian Bao, 37 What is your educational and professional background? I completed my undergraduate studies in Mechanical Engineering at Shanghai Jiaotong University, China. Following that, I earned my Master’s degree from Tohoku University in Japan, where my research focused on computational fluid dynamics simulations involving two-phase flow. Specifically, I worked...

Superconductivity Mystery: Scientists Challenge a 50-Year Theory of Electron Behavior

A recent study found that the Hubbard model failed to accurately predict the behavior of a simplified one-dimensional cuprate system. According to scientists at SLAC, this suggests the model is unlikely to fully account for high-temperature superconductivity in two-dimensional cuprates. Superconductivity—the ability of materials to conduct electricity without energy loss—holds...

IBM to Invest $150 Billion in U.S. Over Next Five Years to Aid Quantum Push

IBM has announced plans to invest $150 billion in the United States over the next five years, marking one of the most significant commitments by a major tech company to bolster American manufacturing and emerging technologies. A substantial portion of this investment, over $30 billion, will be directed specifically toward...

A New Chapter for Carbon Capture

As industries worldwide race toward decarbonization, reliable solutions that balance emissions goals with energy demands remain elusive. But a new partnership between Bloom Energy (NYSE: BE) and Chart Industries (NYSE: GTLS) signals a promising shift—one that could redefine how energy-intensive sectors like data centers and manufacturers approach carbon capture and...

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...

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...

What is the temperature range of cryogenics?

Could you please tell me what is the temperature range of cryogenics? In other words, is -100°F considered cryogenic, or does it start lower? Could I expect to see some extended life in D2 stamping dies? What would the recipe be to achieve the desired results using cryogenics?
