Hyundai Nexo Sets Hydrogen Fuel Cell Distance Record

Celebrity explorer Bertrand Piccard drove Hyundai’s Nexo SUV 484 miles across France in November, setting a new world record for the longest distance traveled in a hydrogen-powered vehicle on a single tank. Within the category of zero-emissions options, the hydrogen fuel cell is constantly being eclipsed by electric power. But...

Cryogenics Secures Volatile Car Batteries in Transit

Early in December, researchers from Warwick Manufacturing Group (WMG) at the University of Warwick UK, in collaboration with Jaguar Land Rover engineers, froze batteries with liquid nitrogen. Research suggests this would allow lithium car batteries—costly and dangerous to move—to be transported safely in a much cheaper and environmentally friendly way.

Electronic Map Reveals ‘Rules of the Road’ in Superconductor

In a study published in the American Physical Society journal Physical Review X (PRX) in early December, Rice University physicist Ming Yi and colleagues offer up a band structure map for iron selenide, a material that has long puzzled physicists because of its structural simplicity and behavioral complexity. The “roadmap,”...

Tour ITER in Virtual Reality

ITER, the world’s largest fusion tokamak, is currently under construction in southern France. Now, operational facilities are under construction including the First Plasma plant and tokamak building. The consortium, comprising representatives from 35 nations, has introduced an interactive worksite tour to keep the public informed on site progress and encourage...

European Space Agency Approves Record Budget To Meet New Challenges

European Space Agency (ESA) members approved a record $15.97 billion budget in late November in Seville, Spain, to secure Europe's position in space exploration as the United States and China press ahead. Funding will allow ESA a full series of programs and additional scientific work including increased Earth observation to...

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...

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?
