Nanoscale Ultra-Fast Microscopy is Now in Your Hands

Semiconductors are foundational components of modern energy, communication, and myriad other technologies. Research on tailoring the underlying nanostructure of semiconductors for optimizing device performance has been ongoing for decades. Now, in a study recently published in Scientific Reports, researchers from the University of Tsukuba and collaborating partner UNISOKU Co., LTD.,...

Tiny Quantum Electronic Vortexes in Superconductors Can Circulate in Ways Not Seen Before

Within superconductors there are little tornadoes of electrons known as quantum vortices that can occur, vortices that have important implications in superconducting applications such as quantum sensors. Now a new kind of superconducting vortex has been found, according to an international team of researchers.[1] Egor Babaev, professor at KTH Royal Institute...

Early Universe Crackled with Bursts of Star Formation, Webb Shows

Among the most fundamental questions in astronomy: how did the first stars and galaxies form? NASA’s James Webb Space Telescope is already providing new insights into this question. One of the largest programs in Webb’s first year of science is the JWST Advanced Deep Extragalactic Survey, or JADES, which will...

RFID Tagging Technology Streamlines Cryogenic Sample Management

Ziath, an Azenta Life Sciences company, announced a revolution in cryogenic sample management – the Ri-Track Mirage 2D barcoded tube whole rack reader. Traditionally, identifying the identity of frost-covered racks of 2D barcoded tubes taken from low temperature storage has been a time-consuming and error-prone process. Drawing upon proprietary Radio Frequency...

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...

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...
