Beam-Beam Compensation Scheme Doubles Proton-Proton Collision Rates at RHIC

Accelerator physicists at the US Department of Energy's (DOE) Brookhaven National Laboratory have successfully implemented an innovative scheme for increasing proton collision rates at the Relativistic Heavy Ion Collider (RHIC), an accomplishment that should in turn produce more data for scientists to sift through to answer important nuclear physics questions,...

Maxwell’s demon as a self-contained, information-powered refrigerator

Scientists at Aalto University in Finland have created an autonomous Maxwell’s demon that makes it possible to analyze the microscopic changes in thermodynamics. The nano-scale device may also facilitate the design of future computers.

Scientists study new alloy that gets tough at low temperature

Just in time for the icy grip of winter: A team of researchers led by scientists from the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has identified several mechanisms that make a new, cold-loving material one of the toughest metallic alloys ever.

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...

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...

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...

Separated layers of ice over a pipe

I want to know that why there are different layers of ice over a pipe carrying a cryogenic fluid, each layer separated with clear marks / lines? What do these layers signify?
