High-Resolution Cryo-EM Starts Focusing on Accessibility

Structure-based designs are integral to advancing drug discovery, and in this regard, cryogenic electron microscopy (cryo-EM) has emerged as a pivotal tool for achieving high-resolution structures of proteins and protein complexes. Particularly noteworthy is its utility in elucidating the structures of protein classes that have historically resisted crystallization. Cryo-EM’s pivotal...

Cryogenic Etch Re-Emerges

Cryogenic etch, sometimes called cryo etch, is one of two ways to enable deep silicon or high-aspect ratio (HAR) etches in devices, where the features are long, narrow and deep. The other and most popular method is the two-step Bosch process, where you etch out a part of the structure...

Tokamak Energy’s Fusion Magnet System Passes Cryogenic Tests

UK-based Tokamak Energy’s superconducting magnet system, which is being built to replicate fusion energy power plant forces, has passed significant milestone cryogenic tests. Creating fusion energy requires strong magnetic fields to confine and control the extremely hot hydrogen fuel, which becomes a plasma several times hotter than the center of...

RegO Adds Pressure Regulators for Cryogenic Vessels

RegO Products has unveiled its latest breakthrough: the CBE504 Series of Half-Inch Pressure Builder-Economizer Regulators. Designed to enhance cryogenic vessel operations, these regulators prioritize pressure control and product preservation. The CBE504 Series boasts numerous improvements over the previous CB504 model, including a more compact form factor and a broader range...

Stability

Stability refers to the ability of a device employing superconductors to remain in its superconducting state after part of the superconductor transitions back to its normal conducting state due to a disturbance. While the concept can apply to many superconducting devices—transmission lines, generators, motors, etc.—it is most commonly considered in...

Cable-in-Conduit Conductors

Cable-in-Conduit Conductors (CICC) are a common form of superconducting cable used in large-scale applications. There are several varieties of CICCs, but they all consist of many small, stabilized superconducting wires contained within a conduit through which a coolant (typically supercritical He II) flows. Figure 1 shows the cross section of...

Bayonet Coupling

A bayonet coupling is a demountable joint that allows for quick and easy connection and disconnection of cryogenic components, including transfer lines, cryostats, liquefiers and refrigerators. Bayonets provide a number of advantages, chief among them the ability to connect and disconnect the bayonets while components they connect are still at...

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...

Looking to purchase new LN2 freezer: any suggestions?

I will be purchasing a new liquid nitrogen freezer soon, but I am limited by space restrictions. The freezer cannot be more than 38 inches wide. However, it would be beneficial if the freezer holds a high number of racks such as 24. In addition, we prefer not to purchase...

Affordable flow meter to measure LN2 flow through a pipeline

I am trying to find out if anyone knows of or has used an affordable flow meter that can measure liquid nitrogen flow through a pipeline. It doesn’t need to be very accurate as it’s really to allow people in different departments to allocate cost rather than for scientific measurement....
