Winners of Bernd T. Matthias Prize for Superconducting Materials announced

Three scientists have been named as recipients of the 2015 Bernd T. Matthias Prize for Superconducting Materials, an international prize awarded for innovative contributions to the field. The prize will be formally presented during the 2015 International Conference on Materials and Mechanisms of Superconductivity in Switzerland this August.

Two CryoTel CT-Fs return to Earth on the Dragon X

NASA confirmed on May 21 that the Space X Dragon successfully splashed down at 12:42 EST in the Pacific. The spacecraft was returning from the International Space Station with two POLAR freezers incorporating a CryoTel CT-F cryocooler in each.

SC study’s reported successes and failures provide valuable data

In their paper "Exploration of new superconductors and functional materials, and fabrication of superconducting tapes and wires of iron pnictides" published in Science and Technology of Advanced Materials, researchers report on four years of extensive research on around 1,000 materials, with detailed insights learned from the new superconducting materials discovered...

LHC arrives at the next energy frontier

The Large Hadron Collider (LHC) is collecting data again for the first time in two years. After powering back on in April and seeing its first record-energy collisions in May, the LHC began colliding particles at a steady rate to provide data for research on June 3. During Run II,...

GTI’s David Carroll assumes presidency of IGU

On June 5, David Carroll, Gas Technology Institute (GTI) president and CEO, assumed the additional role of president of the International Gas Union (IGU) for a three-year term at the closing ceremony of the World Gas Conference in Paris. With the growth of natural gas in the global energy landscape,...

Helium-3

Helium-3 (3He) is one of the two stable isotopes of helium. The other is the much more common Helium-4 (4He). Neither of these isotopes should be confused with He II, which is the second liquid phase of 4He. He II was discussed in this column in the Spring 2010 edition...

Cryopumping

Cryopumping refers to the use of cryogenic temperatures to produce vacuum in enclosed spaces. More broadly, it can also refer to the removal of gases via cryogenic temperatures from a flow stream or enclosure without necessarily resulting in vacuum pressures. This is an important application of cryogenics and is used...

Thermal Acoustic Oscillations

Thermal Acoustic Oscillations (TAO) are a common event in cryogenic systems that can have significant adverse effects on the performance of the system. TAOs are sustained pressure oscillations that can occur in tubes containing gas, closed at one end (the warm end) that have a very large temperature gradient along...

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?
