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,...

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...

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

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...

Need help with temperature dependent model

I am a fourth-year student at New Zealand University. My name is Xu Ke. I have a project to generate a temperature dependent model for inductor, capacitor and diode by using PLECS. PLECS is software which acts as a toolbox for MATLAB. In my models, the temperature is very low,...

In what form is water available in LN2?

Does anybody know in what form water is available in LN2? There probably is a block of ice in the bottom of the tank. But as water comes in many shapes, I can imagine snow or crystals floating free in the LN2. When water is available in LN2, could small...

Separating gases using cryogenics

We are looking for some consulting engineers who understand how to separate gases using cryogenics. We have a new process which takes biomass and converts it to 5 gases and we need to separate these gases into their pure forms. Thanks for your help. Malcolm Draper Energy Research Group LLC...
