Cornell Researchers Create First Self-Assembled Superconductor

After nearly two decades’ worth of research, a multidisciplinary team at Cornell has created a self-assembled, three-dimensional gyroidal superconductor. Ulrich Wiesner, a materials science and engineering professor who led the group, says it’s the first time a superconductor, in this case niobium nitride (NbN), has self-assembled into a porous, 3-D...

Phosphine as a Superconductor?

Phosphine is one of the newest materials to be named a superconductor, a material through which electricity can flow with zero resistance. Scientists first liquefied phosphine in 2015, squeezing it under high pressure in a diamond vice to achieve superconductivity, and now a group of researchers from the University of...

LHC Art Exhibition Opens at the National Academy of Sciences

While the Large Hadron Collider (LHC) is technically tucked away in Geneva, visitors to a new art exhibition in Washington DC may have just been afforded the most unique view available of the facility. “Jonathan Feldschuh: Large Hadron Collider” is a collection of seven paintings inspired by the world’s largest...

Argonne Scientists Inspire the Next Generation of Computational Thinkers

The City of Chicago and the US Department of Energy's (DOE's) Argonne National Laboratory (CSA CSM) came together this winter for a "My Brother's Keeper" event, a one-day hands-on workshop connecting the dots between computational thinking and science, technology, engineering and math (STEM) careers for 8th grade students attending the...

Electrons and Liquid Helium Advance Understanding of Zero-Resistance

Research conducted by the Quantum Dynamics Unit at Okinawa Institute of Science and Technology Graduate University (OIST) in Japan could represent an important step in understanding two-dimensional semiconductors. The unit's latest paper, published in "Physical Review Letters", describes anomalies in the behavior of electrons in an electrons-on-liquid helium two-dimensional system.

Brooks introduces p-Chip Technology for More Reliable Sample Tracking and Security

Brooks Automation (CSA CSM), a global provider of automated sample storage systems and consumables for compound management and biorepositories, has introduced its first commercial sample storage tube incorporating p-Chip® tracking technology. The p-Chip, a unique electronic microtransponder ID tagging technology, is 100 times smaller, far less expensive and more reliable...

Space Cryogenics

Space cryogenics is, somewhat obviously, the application of cryogenics to space exploration and science. The use of cryogenics in space optimizes the launching of vehicles, provides power and life support to spacecraft and is critical for many scientific observations.Space cryogenics has a number of challenges and has driven both pure...

Exergy

The science of thermodynamics plays a major role in cryogenics. It underlies the various refrigeration cycles, from Carnot to Brayton (Cold Facts Vol. 32 No. 2) and Joule-Thomson, is a fundamental part of the definition of terms such as coefficient of performance (Cold Facts Vol. 31 No. 1) and even...

Cryogenic Treatment

Cryogenic treatment is the process of cooling materials to cryogenic temperatures temporarily to improve their material properties at room temperature. This is distinct from cooling materials down to cryogenic temperatures to take advantage of phenomena such as superconductivity that only occur at cryogenic temperatures. Cryogenic treatment, sometimes also referred to...

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...

Presence of alloying elements in tool steels

I want to expand my knowledge of cryogenics in general and tool steels in particular. Specifically, I am keenly interested in learning about the presence of alloying elements in tool steels and how their presence in various combinations affects the performance of tool steels after cryogenic treatment.

Pros and cons of barcoding samples

I was wondering if I could ask for input on pros and cons of barcoding. We are in the process of trying to decide if we should start barcoding our samples and I’m just not sure if this is feasible for our organization. We have numerous sites all over the...
