Par-Baked Goods Gain Ground with Cryogenic Freezing

Fresh-from-the-oven signature breads at retail were once almost the exclusive province of fine restaurants, but the rise of commercial par-baking has made it possible for any restaurateur or food retailer to produce even artisan breads without skilled labor. "Cryogenic freezing of par-baked goods is giving commercial bakers who have only...

UTA Hosts DUNE16 Collaboration Meeting

Over 150 leading international physicists convened in early January at The University of Texas at Arlington to collaborate on the game-changing particle physics experiment known as the Deep Underground Neutrino Experiment, or DUNE.

IUPAC adds four superheavy elements to periodic table

The International Union for Pure and Applied Chemistry (IUPAC) welcomed the new year with a bang, confirming the discovery of four new elements and once again shaking up the periodic table. Elements 113, 115, 117 and 118 complete the seventh row of the table. Each has been assigned a temporary...

Lockheed cuts F-35 part cost with cryogenic machining system

Lockheed Martin engineers have demonstrated a 52 percent increase in cutting speeds associated with roughing and finishing operations on large titanium airframe components for the F-35 program. The tests made use of an Okuma MA-600HII horizontal machining center equipped with 5ME’s patented cryogenic machining system.

NIST researchers enhance photon detection accuracy

National Institute of Standards and Technology (NIST) researchers announced on January 5 advances in the fabrication of superconducting nanowires that improve the precision of detecting individual particles of light by 74 picoseconds.

Oxford and Zurich Instruments collaborate to improve low temperature measurements

Oxford Instruments NanoScience (CSA CSM) on January 7 announced a new technical collaboration with Zurich Instruments, a leader for digital lock-in amplifiers, focused on combining equipment from both companies in order to reduce the time between installation and measurement in cryogenic systems.

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...

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

ASTRONOMY IN SPACE by Peter V. Mason, retired, Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere. On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
