DESY Research Points to Liquid Oxygen in Earth’s Core

Using a special high-pressure chamber, scientists have discovered two new iron oxides in experiments at DESY's X-ray light source PETRA III and other facilities. The discovery points to a huge, hitherto unknown liquid oxygen source in the lower mantle of the Earth. The team, led by Dr. Elena Bykova from...

Japanese Researchers Superconduct Graphene

Scientists in Japan have developed superconductive graphene, according to research published in ACS Nano. Graphene is a single-atomic carbon sheet with a hexagonal honeycomb network. Electrons in graphene take on a special electronic state called the Dirac-cone, where the electrons behave as if they have no mass. This allows the...

NASA Introduces WFIRST, a “Wider Set of Eyes” on the Universe

After years of preparatory studies, NASA is formally starting an astrophysics mission designed to help unlock the secrets of the universe—the Wide Field Infrared Survey Telescope (WFIRST). With a view 100 times bigger than that of NASA’s Hubble Space Telescope, WFIRST will survey large regions of the sky in near-infrared...

Gravitational Waves Detected 100 Years after Einstein’s Prediction

Scientists have for the first time observed ripples in the fabric of spacetime called gravitational waves, confirming a major prediction of Albert Einstein’s 1915 general theory of relativity and opening an unprecedented new window onto the cosmos. The discovery was made possible by the enhanced capabilities of Advanced LIGO, a...

Researchers Designing Safer Cryotherapy Devices

Researchers at the University of Texas at Arlington and the University of Texas at Austin are developing a state-of-the-art cryotherapy device, one that can stimulate blood flow to keep tissue healthy and minimize potential side effects, and what are believed to be the first formal protocols for effective and safe...

Cryofab Honored by Rothman Institute

The Rothman Institute has nominated Cryofab (CSA CSM), a manufacturer of cryogenic equipment, for New Jersey Family Business of the Year for 2015, recognizing the company's impact on the community and its perseverance, business success and commitment to family.

Liquid Hydrogen

Hydrogen becomes a liquid at 20K and 1 bar. Liquid hydrogen (LH2) is an important substance in industry, transportation and research. Industrial uses of hydrogen include applications in the electronics, glass, chemical and metal processing fields. In these applications, the hydrogen is generally used as a room temperature gas but...

Superconducting Radiofrequency Cavities

Superconducting radio frequency (SRF) cavities represent an important application of cryogenics and superconductivity. SRF cavities are a technology for accelerating charged particle beams via the transfer of radiofrequency (RF) energy to the beams via resonant structures. As such, they are frequently found in large particle accelerators used for scientific research....

Thermal Radiation Shields

Actively cooled thermal radiation shields are a common feature of cryostats whose lowest temperature is less than 77K. These shields, which typically operate at temperatures between that of LN2 and 40K, block thermal radiation from higher temperatures from reaching lower temperature cryogenic components or fluids. Since the heat radiated from...

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...
