Book Review: The Safe Use of Cryogenic Technologies by Robert Done

It is becoming common for large-scale scientific projects to include cryogenic systems provided by other countries. Examples of this include CERN, the European Spallation Source, ITER and the PIP II project at Fermilab (CSA CSM). While these contributions are quite valuable, one of the big challenges in such projects is...

Cool Fuel: Hydrogen, Lenses and Lasers, Oh My!

The bar for getting the suffix of PhD after your name is high – you have to fundamentally change the philosophy in a field. As a faculty member responsible for training some of these individuals, I’m sometimes faced with the conundrum that advancing the philosophy implies that I have to...

Groundbreaking Alternative to Invasive Breast Cancer Surgery Now Available in Monroe NJ

Patients in Central New Jersey with early-stage breast cancer can now access a highly effective treatment that does not require traditional invasive surgery. Performed at Princeton Radiology's Minimally Invasive Care Center in Monroe Township by interventional radiologist Kenneth R. Tomkovich, MD, the procedure, called cryoablation, uses a small needle and...

INEOS Announces over €2 Billion Investment in Green Hydrogen Production

INEOS has announced that it is to invest more than €2 billion into electrolysis projects to make zero carbon, green hydrogen across Europe. Its first plants will be built in Norway, Germany, Belgium with investment also planned in the UK and France. The announcement was made on October 18. INEOS,...

Heating Up Quantum Science Education with Laser Cooling

A series of interactive workshops developed by Columbia University physicist Sebastian Will and STEMteachersNYC will give educators tips and tools to cover quantum science in their classrooms. If you imagine a laser, you might think of beams of light popping balloons or slicing through a metal slab like butter. Lasers...

Laurentis Energy Partners Launches Helium-3 Production

Laurentis Energy Partners, in the fall of 2021, launched its program to produce Helium-3 (He-3), a rare and valuable isotope used in quantum computing, neutron research, border security and medical imaging. Laurentis will obtain the He-3 from tritium stored at the Darlington Nuclear Generating Station, about 100 kilometers east of...

Regenerators

Regenerators or regenerative heat exchangers are a key component of cryocoolers such as pulse tube cryocoolers (Cold Facts, August 2014). Regenerator performance greatly affects the coefficient of performance of cryocoolers. Improvements in regenerator design and, in particular, regenerator materials have been an important factor in the improvement of the performance...

Pulse Tube Cryocoolers

The development of pulse tube cryocoolers has been a significant topic of research and development over the past 20 or so years. Pulse tube cryocoolers have a number of advantages over other types of cryocoolers and are now available commercially. In order to understand pulse tube cryocoolers, it’s best to...

Thermal Expansion

Thermal expansion refers to the change in size (length or volume) that a material undergoes as its temperature changes. In cryogenic systems this effect can be quite large and must be allowed for in the design. In isotropic materials, which include most engineering materials, the thermal expansion is the same...

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...
