Omani and Chinese R&D Entities to Study Hydrogen Liquefaction

The Sustainable Energy Research Centre (SERC), a prominent Omani research facility based at Sultan Qaboos University (SQU), has announced a partnership with China’s SinoScience Clean Energy Technology Co. Ltd. The collaboration aims to identify technologies that will enable the liquefaction of green hydrogen for export. SinoScience, headquartered in the Chinese...

For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI)

NASA Webb Identifies Frozen Water in Young Star System

Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system. Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris...

South Korea to Invest $39.2M in Large-Scale Liquid Hydrogen Carriers

South Korea has announced plans to invest 55.5 billion won ($39.2 million) in the development of large-scale liquid hydrogen carriers, with the goal of launching a demonstration ship by 2027. The project is part of the country’s broader effort to take a leading role in the emerging global hydrogen economy....

Interlune Secures Helium-3 Agreements with Maybell Quantum and U.S. Department of Energy

Interlune, a U.S.-based space resources company, has signed landmark agreements to supply lunar-sourced helium-3 to both Maybell Quantum and the U.S. Department of Energy (DOE). Maybell Quantum will be Interlune’s first commercial customer, receiving thousands of liters of helium-3 annually from 2029 to 2035. The helium-3 will support Maybell’s advanced...

Atomic-Scale Imaging Unlocks New Paths to Next-Gen Superconductors

Atomic-scale imaging reveals that chalcogen atoms play a crucial role in Cooper pairing in Fe-based superconductors, offering new insights into high-Tc superconductivity mechanisms. Superconductivity in quantum materials, whether the Cooper pairing on the Fermi surface is mediated by phonons or by electronic fluctuations, is fundamentally described by Bardeen-Cooper-Schrieffer (BCS) theory....

Superconductivity Inspires New Dark Matter Contender

As traditional dark matter candidates—such as weakly interacting massive particles (WIMPs), axions, and primordial black holes—continue to elude detection, theorists are exploring more exotic possibilities. Guanming Liang and Robert Caldwell of Dartmouth College have proposed a new dark matter model inspired by the physics of superconductivity [1]. Their proposal draws...

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...

Thermal shock on steel cylinder when dropped into liquid nitrogen

We are a research team at the University of South Florida, studying the “thermal shock” on a steel cylinder when it is dropped into liquid nitrogen. We want to make sure that the thermocouple does not get influenced by the surrounding LN2. Any advice?

Getter materials to absorb out gassed materials?

Here’s one for the scientists: We would like to sell vacuum insulated pipe for high temperature fluid applications. Are there any good getter materials that we can place in the vacuum space of our VJP to absorb outgassed materials at elevated temperatures?
