Physicists have found "electron pairing," a hallmark feature of superconductivity, at temperatures and energies well above the critical threshold where superconductivity happens.
While trying to replicate another team's finding, Stanford physicists recently stumbled upon a novel form of magnetism—predicted but never seen before—that is generated when two honeycomb-shaped lattices of carbon are carefully stacked and rotated to a special angle.
Technicians and engineers at NASA have recently tested a key part of the James Webb Space Telescope deployment choreography by successfully commanding Webb to deploy the support structure that holds its secondary mirror in place. This is a critical milestone in preparing the observatory for its journey to orbit. The...
The European Space Agency's Euclid mission, set to launch in 2022, will investigate two of the biggest mysteries in modern astronomy: dark matter and dark energy. A team of NASA engineers recently delivered critical hardware for one of the instruments that will fly on Euclid and probe these cosmic puzzles.
Researchers at the University of Illinois at Urbana-Champaign, collaborating with scientists at the SLAC National Accelerator Laboratory, have shed new light on how disparate states can exist adjacent to one another. Illinois Physics post-doctoral researcher Matteo Mitrano, Professor Peter Abbamonte and their team applied a new X-ray scattering technique, time-resolved...
Researchers used 3D porous Polycaprolactone (PCL) scaffolds with combined extrusion-based cryogenic 3D printing and freeze-drying in an attempt to overcome existing limitations like affordability, lack of efficiency in fabrication and inferior process control.
Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...
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...
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...
We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?
Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
I am looking for data on Carbon Fibres Reinforced Plastic at temperatures between 4 and 300K. I would appreciate it if someone could give me some hints on where to find it.
