DOE Announces New Lab Consortia to Advance Hydrogen, Fuel Cells

On June 23, the US Department of Energy announced that it will invest up to $100 million over five years in two new DOE National Laboratory-led consortia to advance hydrogen and fuel cell technologies research and development. One consortium will seek to achieve large-scale, affordable electrolyzers which use electricity to...

Rice Physicist Earns Grant to Study Magnetism

On June 23, the Department of Energy’s Office of Basic Energy Sciences awarded Rice University experimental physicist Ming Yi a five-year grant to explore the details of magnetism in two-dimensional materials. She and her colleagues seek to learn the origin of magnetism in bulk materials that are exfoliated for use...

Electricity Transmission Reaches Even Higher Intensities at CERN

In CERN’s superconducting equipment testing hall, an innovative transmission line has set a new record for the transport of electricity. The 60-meter long link has transported a total of 54,000 amperes (54 kA, or 27 kA in either direction). The line has been developed for the High-Luminosity LHC (HL-LHC), the...

Scientists Use Pressure to Make Liquid Magnetism Breakthrough

Using two flat-top diamonds and a lot of pressure, scientists at Argonne National Laboratory (CSA CSM) have forced a magnetic crystal into a spin liquid state, which may lead to insights into high temperature superconductivity and quantum computing.

CERN Researchers Create, Study New Exotic Atom at Paul Scherrer Institute

A team of researchers from CERN’s Atomic Spectroscopy and Collisions Using Slow Antiprotons (ASACUSA) collaboration have taken experimental equipment from CERN to the Paul Scherrer Institute near Zurich to create a theoretically predicted, but never before verified, exotic atom and made first measurements of how it absorbs and resonates with...

Latest in Defining Cryogenics

Adiabatic Demagnetization Refrigeration

Reaching temperatures below 1K requires different techniques than the various helium gas cycles found in large scale refrigeration plants and small cryocoolers. One of these techniques is Adiabatic Demagnetization Refrigeration (ADR). This technique takes advantage of the fact that the entropy of paramagnetic materials in a magnetic field is lower than...

Cryogen-Free

A cryogen is any fluid that operates at cryogenic temperatures (below roughly 150K – 120K). Using this definition, helium gas at 40K is a cryogen. Another more restrictive definition is to use cryogen to refer specifically to liquids at cryogenic temperatures. This is generally how it is used in the...

Cryostats and Cryocoolers

A cryostat is any device designed to maintain things (including fluids) at cryogenic temperatures. In general usage, cryostats tend to be passive devices rather than providing active cooling. In this usage, cryostats keep things cold by thermally isolating them from room temperature. This generally is accomplished by a combination of...

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...

Effect of cryogenic freezing on tone of bell?

I have been making bells for a few years out of Bell Bronze, 87% Copper. Would cryogenic freezing have any effect on the tone of a bell if I had it treated after casting? Your help would be appreciated.

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?

Could boxes of paper records be freeze-dried?

In the event of a disaster such as a flood, could boxes of paper records be freeze-dried? Could cryogenics help in the recovery efforts?
