Atomic-resolution images provide fresh insights into a mysterious state found in superconducting materials
Superconductivity describes the state of certain materials when they conduct electric currents without any resistance. For superconductivity to develop, these materials generally have to be cooled to temperatures ...
Salt power: Watt's next in rechargeable batteries?
Reza Shahbazian-Yassar thinks sodium might be the next big thing in rechargeable batteries.
Chemists find smallest number of water molecules needed to form an ice crystal
Scientists first to mimic nature's vital potassium ion channel
(Phys.org) -- An international team of scientists, including chemist Xiao Cheng Zeng of the University of Nebraska-Lincoln, has created what is in effect a nanoscale sieve that is very selective in what it ...
Making sodium-ion batteries that are worth their salt
(PhysOrg.com) -- Although lithium-ion technology dominates headlines in battery research and development, a new element is making its presence known as a potentially powerful alternative: sodium.
Under pressure, sodium and hydrogen could undergo a metamorphosis, emerging as a superconductor
(PhysOrg.com) -- In the search for superconductors, finding ways to compress hydrogen into a metal has been a point of focus ever since scientists predicted many years ago that electricity would flow, uninhibited, through ...
Ground-based lasers vie with satellites to map Earth's magnetic field
(PhysOrg.com) -- Mapping the Earth's magnetic field to find oil, track storms or probe the planet's interior typically requires expensive satellites.
Water Motions Revealed (w/ Video)
(PhysOrg.com) -- Gaze into a glass of water, and you're unlikely to see much more than your own reflection. But gaze a little deeper using a microscope -- or, better yet, a series of laser pulses and detectors ...
The smell of salt air, a mile high and 900 miles inland
The smell of sea salt in the air is a romanticized feature of life along a seacoast. Wind and waves kick up spray, and bits of sodium chloride - common table salt - can permeate the air.
Jets on Saturn's moon Enceladus not geysers from underground ocean
Water vapor jets that spew from the surface of Saturn's icy moon Enceladus are not really geysers from an underground ocean as initially envisioned by planetary scientists, according to a study led by the ...
Flatland physics probes mysteries of superfluidity
(Physorg.com) -- If physicists lived in Flatland—the fictional two-dimensional world invented by Edwin Abbott in his 1884 novel—some of their quantum physics experiments would turn out differently (not ...
