Manchester Group Discovers New Family of Quasiparticles in Graphene-Based Materials

A group of researchers led by Sir Andre Geim and Dr Alexey Berdyugin at the UK University of Manchester have discovered and characterized a new family of quasiparticles named "Brown-Zak fermions" in graphene-based superlattices. The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of...

Preparatory ‘Pre-lab’ Proposed for ILC

On September 10, the International Committee for Future Accelerators announced the structure and members of a new organizational team to prepare a “pre-laboratory” for an International Linear Collider in Japan. The ILC International Development Team, which consists of an executive board and three working groups—governing the pre-lab setup, accelerator, physics...

REBCO HTS Wire Manufacturer SuperPower Relocates to New Facility

On August 24, SuperPower Inc. (CSA CSM), a wholly owned subsidiary of Japan’s Furukawa Electric Company, Ltd., announced that it has completed its move and is now operating from a new facility in Glenville NY. The company is a world leader for the development and manufacturing of REBCO-based second generation...

Berkeley Lab Selected to Lead Next-Generation Cosmic Microwave Background Experiment

The largest collaborative undertaking yet to explore the relic light emitted by the infant universe has taken a step forward with the US Department of Energy’s selection of Lawrence Berkeley National Laboratory (Berkeley Lab) to lead the partnership of national labs, universities and other institutions that will carry out the...

Cryogenics Contributes to Lifesaving Pandemic Treatments, Research

For the past seven months, the US has been fighting alongside the rest of the world to reign in COVID-19. From cutting-edge research and technical developments to recovery routines and last-line-of-defense treatments, cryogenics has played a number of roles—some expected and some surprising—to aid in the international response to the...

Birth of Cloned Przewalski’s Foal Offers Genetic Diversity for Endangered Species

On August 6, 2020, the world’s first successfully cloned Przewalski’s horse was born in Texas at the veterinary facility of a ViaGen Equine collaborator, Timber Creek Veterinary. The foal, born to a domestic surrogate mother, is a clone of a male Przewalski’s horse whose DNA was cryopreserved 40 years ago...

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...

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...
