LCLS X-ray Laser Reveals Ultrafast Riboswitch in Action

Scientists have used the powerful X-ray laser at the Linac Coherent Light Source (LCLS), located at the Department of Energy’s SLAC National Accelerator Laboratory, to take the first ever snapshots of an ultrafast riboswitch, a gene regulator that can switch individual genes on and off. According to the research team,...

Stanford Study Suggests Battery Power Will Trump Hydrogen Fuel Cells

Stanford researchers say communities would be better off investing in electric vehicles that run on batteries instead of hydrogen fuel cells, in part because a hydrogen infrastructure provides few additional energy benefits for communities beyond clean transportation.

CoEPP and IHEP to Collaborate on Future Experiments

At a ceremony held Nov. 8 in Beijing, representatives from the ARC Center for Particle Physics at the Terascale (CoEPP) and the Institute of High Energy Physics (IHEP) signed a Memorandum of Understanding to establish scientific exchange, collaboration and cooperation between the two organizations.

Cooling Technique Improves Antiproton Mass Measurement

Scientists from CERN's ASACUSA experiment have announced a new precision measurement of the mass of the antiproton relative to that of the electron, a result based on spectroscopic measurements of approximately two billion antiprotonic helium atoms cooled to temperatures near absolute zero.

ASC 2016 Highlights Progress in Superconductivity

Over 1,600 researchers and engineers from 36 countries gathered in Denver September 4-9 for ASC 2016, attending plenaries, poster sessions and meetings under the watchful gaze of the Colorado Convention Center’s Blue Bear. Celebrating its 50th year, the conference covered a wide range of topics, from superconducting electronics detectors and...

2016 ASC Best Student Paper Contest

The Applied Superconductivity Conference's Best Student Paper Contest recognizes outstanding presentations made at ASC by full-time students. The ability to describe one’s research, by succinctly capturing key results and ideas in written form as well as by presenting and defending the work in front of an audience of experts, is...

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...

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...
