Both Frozen and Fresh Embryos Offer Similar Chances of Baby after IVF for Most Women

For women using in vitro fertilization to have a child, using either fresh or frozen embryos results in similar success rates for most women, according to an international team of researchers.

Researchers Engineer Ultra Sensitive Temperature Sensor

Researchers in Brazil have created an optical thermometer capable of measuring temperatures from 750 to 80 K. It operates in real time and in well-defined regions with a spatial resolution ranging from a centimeter to a micrometer. It also has practically no effect at all on the temperature of the...

Researchers Cool Chip Below 3 mK, Establish New Low Temperature Record

Physicists at the University of Basel in Switzerland have succeeded in cooling a nanoelectronic chip to a temperature lower than 3 mK. The research team used magnetic cooling to cool the electrical connections as well as the chip itself.

Dark Energy Survey Publicly Releases Data Trove

Scientists on the Dark Energy Survey publicly released data from the project's first three years during a special session held at the American Astronomical Society meeting in Washington DC. The release includes information on about 400 million astronomical objects, from distant galaxies billions of light-years away to stars in our...

Separate Research Teams Advance Quantum Simulators

Researchers at the Harvard-MIT Center for Ultracold Atoms and at the Joint Quantum Institute at the University of Maryland have announced complementary advances in quantum studies that constitute a major step towards the realization of large-scale quantum machines.

ITER Passes 50 Percent Marker on Journey to First Plasma

The International Thermonuclear Experimental Reactor (ITER), a project to prove that fusion power is both sustainable and producible on a commercial scale, reached a major milestone at the end of 2017 when construction work towards “First Plasma” passed 50 percent.

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...

You are encouraged to read Cryo Central’s History...

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...

Need help comparing chest freezers and upright freezers

Currently we use in our Biobank an upright -80 freezer to store all our samples. We are planning to buy a fully automated bio-repository storage that will do the picking of samples under restricted conditions. But in the meantime I foresee that we have to pick the samples manually. The...

Need recommendations for cryogenic vials

I am looking into standardizing our range of bio storage tubes (cryogenic vials). These will be for both blood and tissue samples and their derivatives. Any recommendations, comments on Micronics, Nalgene, Nunc and or others that are suitable for long term -80 C and -196 C storage, DNA/RNA suitable, would...

We need a custom machine for flash freezing of water

We are an ice making company and have started a new project, which is related to flash freezing of water. It is based on cryogenics technology and we need a custom made machine. I would kindly ask you to pass me a few companies who would be interested in such...

Looking for a pump suitable for cold liquids

I would like to construct a small cooling circuit (appr. 50 x 50 cm) pumping liquid at a temperature down to -120°C from a cold reservoir to the specimen to be cooled. The tubes and connections are not a problem, but does somebody know a pump (suction/compression for circulation) suitable...
