CUORE Reaches Its Operating Temperature

The Cryogenic Underground Observatory for Rare Events experiment (CUORE) reached a new milestone in late January when its detector reached its operating temperature of 10 mk. The detector has 19 towers formed from 988 Tellurium oxide crystals, and it weighs nearly 1,650 lbs. Engineers finished installing the detector into the...

Improving LED Screens with Scotch Tape and Laser Beams

Researchers at the Ultrafast Laser Lab at the University of Kansas have created a new bilayer material that someday could lead to more efficient and versatile light emission. Each layer, formed by combining atomically thin layers of molybdenum disulfide and rhenium disulfide, measures less than one nanometer in thickness.

New Report Details Communication Best Practices for Science Labs and Facilities

The InterAction Collaboration, a group of science communicators from 18 laboratories and institutions from 11 countries, has issued a new report summarizing communication best practices. It covers more than a dozen categories of communication and outreach activities, including managing reputational risks through communications, strategic approaches to communications and outreach, traditional...

ISRO Successfully Tests the GSLV MkIII Cryogenic Upper Stage

The Indian Space Research Organization (ISRO) completed a flight duration test for the cryogenic upper stage of its GSLV MkIII in mid-February. The move marked a significant milestone, according to ISRO, as the 640-second test was the last in series of engine and stage development hot tests before the launch...

Industry Team Developing High-Efficiency Hydrogen Compressor

Sustainable Innovations, Inc., Greenway Energy and Savannah River National Laboratory have announced a partnership designed to maximize the benefits of two cutting edge hydrogen compressor technologies by combining them into one hybrid compressor with both high reliability and efficiency.

Highview Expands LAES Offerings in NYC

Highview Power Storage, a designer and developer of large-scale energy storage solutions for utility and distributed power systems, has agreed to enter ACRE, New York City’s business incubator for smart cities, smart grid and clean energy at the Urban Future Lab (UFL) located at the NYU Tandon School of Engineering.

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
