Induced Flaws in Quantum Materials could Enhance Superconducting Properties

In a surprising discovery, an international team of researchers, led by scientists in the University of Minnesota Center for Quantum Materials, found that deformations in quantum materials that cause imperfections in the crystal structure can actually improve the material’s superconducting and electrical properties.

The groundbreaking findings could provide new insight for developing the next generation of quantum-based computing and electronic devices.

The research just appeared in Nature Materials, a peer-reviewed scientific journal published by Nature Publishing Group.

“Quantum materials have unusual magnetic and electrical properties that, if understood and controlled, could revolutionize virtually every aspect of society and enable highly energy-efficient electrical syst...

Glycerin is Safe, Effective in Psoriasis Model

Patients with psoriasis have reported that glycerin, an inexpensive, harmless, slightly sweet liquid high on the list of ingredients in many skin lotions, is effective at combatting their psoriasis and now scientists have objective evidence to support their reports.

They found that whether applied topically or ingested in drinking water, glycerin, or glycerol, helps calm the classic scaly, red, raised and itchy patches in their psoriasis model, Dr. Wendy Bollag, cell physiologist and skin researcher at the Medical College of Georgia and Charlie Norwood VA Medical Center and her colleagues report in the International Journal of Molecular Sciences.

The studies also provide more evidence of the different ways glycerin enables the healthy maturation of skin cells through four stages...

New research into metal-rich asteroids reveals information about the origins and compositions of these rare bodies that could one day be mined. Metal-rich near-Earth asteroids, or NEAs, are rare, but their presence provides the intriguing possibility that iron, nickel and cobalt could someday be mined for use on Earth or in Space.

New research, published in the Planetary Science Journal, investigated two metal-rich asteroids in our own cosmic backyard to learn more about their origins, compositions and relationships with meteorites found on Earth.

These me...

Unusual Material could Improve the Reliability of Electronics and other devices

Crystalline sheets
Random twists between layers of crystalline sheets block heat going through the layers, but still maintain good heat flow along the sheets. Researchers measure an astonishing factor of 900 in the difference in heat flow.

Moving heat around where you want it to go—adding it to houses and hairdryers, removing it from car engines and refrigerators—is one of the great challenges of engineering.

All activity generates heat, because energy escapes from everything we do. But too much can wear out batteries and electronic components—like parts in an aging laptop that runs too hot to actually sit on your lap. If you can’t get rid of heat, you’ve got a problem.

Scientists at the University of Chicago have...
