Motor Protein Dynamics Guide Brain Disease Drug Targeting; Cryo-EM Technology at Work

The cell cytoskeleton is modulated by motor proteins, known as dyneins, that generate force and movement on microtubules to control a wide range of biological processes, including motility, cell division, and intracellular transport. Mutation of Lis1, a key dynein regulator, can lead to the rare mental developmental disorder lissencephaly, or...

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...

Joule-Thomson Effect

The Joule-Thomson (JT) effect is a thermodynamic process that occurs when a fluid expands from high pressure to low pressure at constant enthalpy (an isenthalpic process). Such a process can be approximated in the real world by expanding a fluid from high pressure to low pressure across a valve. Under...

Current Leads

One of the challenges of using superconducting magnets is the connection of the magnet to a room temperature power supply. This is accomplished via current leads. The trick is that current leads should ideally have a low heat leak, since they connect room temperature to cryogenic temperature, while at the...

Multilayer Insulation

Multilayer insulation (also referred to as superinsulation) is a key component in the reduction of heat leak to cryogenic systems due to thermal radiation. MLI consists of a series of uncooled reflective surfaces placed in the vacuum space between two surfaces, one warmer than the other. Generally speaking, for ideal...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...

Liquefied Natural Gas

Liquefied Natural Gas as it relates to the Field of Cryogenics John W. Bonn VJ Systems, LLC johnbonn@vjsystems-lic.com Today the world is looking for a cleaner fuel and Liquefied Natural Gas (LNG) plays a large part in achieving this goal. LNG in a liquid form is at -162°C (-259°F) and...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
