Award Abstract # 1701077. Superfluidity in Helium Nanodroplets. This project focuses on the properties of nanoscopic droplets made from helium, which remains liquid at temperatures down to absolute zero (-460 °F). At low enough temperatures, the droplets lack any viscosity, at which point they are said to be superfluid.

Key to the effect is helium's unique ability to remain liquid down to absolute zero (–459.67 degrees F, or –273.15 degrees C), the temperature at which atoms theoretically stop moving.

At 2.2 kelvin, the liquid helium suddenly began to behave strangely, flowing without apparent viscosity. The state reminded Kapitsa of a superconductor, so he dubbed it a "superfluid." Theorists quickly connected some of the dots: liquid helium-4 was a Bose-Einstein condensate whose atoms congregated at a ground state, creating a viscosity ...

Liquid Helium-3: The low-temperature properties of the rare isotope provide a basis for a new theory of liquids. J. G. Daunt Authors Info & Affiliations. Science. 26 Feb 1960. Vol 131, Issue 3400. pp. 579 - 585. DOI: 10.1126/science.131.3400.579.

The helium shortage that last year forced many scientific users to get by with less than half of their pre-2022 usage levels has eased a bit, according to a wide variety of users. (See " Helium is again in short supply," Physics Today online, 4 April 2022.) Yet prices continue to soar above the already high levels of a year ago, they say.

When liquid helium-3 is cooled to millikelvin temperatures, it transitions into a state of matter called a superfluid. From the outside, superfluid helium-3 looks like a simple, transparent medium. Nevertheless, its internal structure is extremely rich and is often described as "the Universe in a droplet" . In helium-3, some atoms ...

One selling point: the tremendous cost savings. "We've captured approximately 2,500 liters of liquid helium — nearly 2 million liters of helium gas — since June 2022," says Samrat Amin, the director of Core Research Facilities operations. At today's average price of liquid helium, the recovery system has already saved the …

Helium is named after the Greek word for the sun, helios, as it was first identified in the sun's corona (the sun is composed of 25% helium). The second most abundant element in the universe, helium is scarce on Earth. A product of nuclear fusion and radioactive decay, it is the lightest noble gas, colorless, odorless, and inert with a low ...

Solid and liquid phases. Helium is the only element that cannot be solidified by lowering the temperature at ordinary pressures; this must be accompanied by a pressure increase. The volume of solid helium, 3 He and 4 He, can be decreased by more than 30% by applying pressure. Solid helium has a projected density of 0.187 ± 0.009 g/mL at 0 K ...

And Stuart Brown, a UCLA condensed-matter physicist, says his cost for liquid helium jumped 15% this spring, even though UC has a systemwide helium supply contract from Matheson. "No supplier has told me the stops are off, you can get all the helium you need," says Joseph DiVerdi, a Colorado State University chemist who orders …

Here are 10 things you may not know about superconductivity: Onnes was also first to create liquid helium, which he did on July 10, 1908. Helium becomes liquid at 4.2 K and is the coolant of choice for low-temperature superconductors in such modern applications as particle accelerators, superconducting magnets, magnetic resonance …
