Lightweight Supramolecular Material for Compressed Hydrogen Storage

A team of chemists from the University of Hong Kong, Northwestern University, and Duke University has developed a supramolecular material capable of compressing hydrogen for storage without being too heavy. Their study, published in Nature Chemistry, demonstrates the use of porous organic crystals for hydrogen storage. Hydrogen has long been...

Cryogenic Therapy Puts the Freeze on Esophageal Cancer

Patients with esophageal tumors often experience malignant dysphagia, or difficulty swallowing due to an obstruction, complicating their treatment and preventing them from eating normally. The Advanced Center for Therapeutic Endoscopy at WVU Medicine J.W. Ruby Memorial Hospital is the first in West Virginia to offer an innovative solution to this...

First Modern Liquid Oxygen Manufacturing Plant To Be Constructed At Tatu Industrial Park

Hewatele, a company based in Kenya that focuses on providing medical-grade oxygen and other healthcare solutions, held a groundbreaking ceremony for the construction of East Africa’s first modern liquid oxygen manufacturing plant, designed to address the rising demand for medical-grade liquid oxygen in healthcare facilities throughout the region. The advanced cryogenic medical...

Rising Helium Demand Set to Double by 2035

A new report from IDTechEx suggests that global helium demand is set to double by 2035, driven by the wide-ranging applications of this vital element. Helium, a finite yet critical resource, is indispensable across multiple industries. From medical imaging to semiconductor manufacturing, helium’s unique properties—such as high thermal conductivity, chemical...

Superconductor Offers Possible Room-Temperature Bridge

A new superconducting compound offers a bridge to more practical superconductors with a potentially attractive range of applications, according to new research. And the new material’s strange magnetic behavior recalls classic superconductors of decades ago—but this time in a material that’s already demonstrated its near-room-temperature bona fides. Lanthanum hydrides—which combine atoms of the...

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...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Elie K. Track Hypres, Inc. elie@hypres.com http://www.hypres.com/ Primary standards involve the exact definition and realization of units of measurement for various quantities, time, length, mass, voltage, resistance, current, etc. International agreements based on the latest scientific knowledge define those units, and their realizations vary depending on the unit itself. For...

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...
