ASC to Hold All-virtual Conference October 24-November 7

The 2020 Applied Superconductivity Conference (ASC) will be held virtually over two weeks beginning October 24 and will offer a combined virtual platform for plenary, oral and poster presentations, a conference exhibition, a new program for young professionals called ELEVATE, virtual breakouts, coffee breaks and other features.

A Quantum Thermometer to Measure the Coldest Temperatures in the Universe

On August 20, Trinity College Dublin announced that physicists from the college have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. These ultracold temperatures arise in clouds of atoms, known as Fermi gases, which are created by...

Lake Shore Cryotronics Acquires Janis Research’s Laboratory Cryogenics Business

On August 5, Lake Shore Cryotronics (CSA CSM) announced the acquisition of Janis Research’s Laboratory Cryogenics (CSA CSM) business—a move that unites two of the world’s foremost providers of cryogenic and material characterization solutions for low temperature research. The acquisition of the Woburn MA-based business allows Lake Shore to now...

Barber-Nichols Wins 2020 CMA Aerospace Manufacturer of the Year Award

Barber-Nichols, a supplier of electronics enhanced turbomachines and turbomachine-based subsystems for the aerospace, defense and cryogenics industries, was named one of the winners of the fifth annual Colorado Manufacturing Awards (CMA)—hosted by CompanyWeek and Manufacturers Edge, a NIST Manufacturing Extension Partnership partner—as “Aerospace Manufacturer of the Year.” Winners were announced...

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...
