Maglab Scientists Use NMR in Battle Against Influenza

Scientists at the National High Magnetic Field Laboratory (Maglab) (CSA CSM) have detailed the mechanism that activates influenza and permits it to reproduce in human cells. The research, published in Structure, shows for the first time how protons move through the virus’s M2 proton channel and portends the development of...

LHC ends 2015 with a cliffhanger

The final Large Hadron Collider results of the year are in. Particles circulated in the LHC at CERN on December 13 for the last time in 2015, and, two days later, the two large general-purpose experiments, ATLAS and CMS, presented their results from LHC Run 2. Both experiments saw an...

QuAIL project announces advances in quantum tunneling achieved on D-Wave 2X

NASA welcomed members of the news media on December 8 to tour its Quantum Artificial Intelligence Laboratory (QuAIL) at Ames Research Center, providing attendees a rare glimpse inside the facility that houses the 1,097-qubit D-Wave 2X quantum computer. Researchers on NASA’s QuAIL team are using the system to investigate areas...

Improved LUX sensitivity helps redefine dark matter search parameters

Scientists working on the Large Underground Xenon (LUX) dark matter experiment are closer to ruling out the possibility of dark matter detections at low-mass ranges. The new findings come after researchers enhanced LUX's ability to look for WIMPS, or weakly interacting massive particles, and thereafter reexamined data collected during LUX's...

TRIUMF and KEK strengthen partnership to advance physics research

At a signing ceremony hosted on December 4 at the Canadian Embassy in Japan, the heads of Canada’s TRIUMF and Japan’s KEK signed a new partnership agreement to enhance research collaborations between the two centers and promote joint projects in the areas of subatomic physics, accelerator science and materials science.

Researchers developing shoebox-sized particle accelerator

The Gordon and Betty Moore Foundation in November awarded $13.5 million to Stanford University for an international effort, including key contributions from the Department of Energy’s SLAC National Accelerator Laboratory, to build a working particle accelerator the size of a shoebox. The technique, based on a technology known as “accelerator...

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...

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...
