Tech Xplore / Half-millimeter-thick battery could be worn in a wrinkle-smoothing patch
(Phys.org)—As the batteries under development in today's research labs are looking less like large blocks of metal and more like pieces of plastic wrap, their novel applications are coming closer to reality. One of the latest ...
Phys.org / Magic states offer surprisingly low error rates for quantum computing
(Phys.org)—Quantum computers hold a special allure, as they offer a way to harness quantum phenomena and put it to use to do things that are impossible for ordinary computers. But as powerful as quantum computers could be, ...
Phys.org / Loophole in theory offers insight into the 'lithium problem'
(Phys.org)—There's not as much lithium in the universe as predicted, and scientists aren't sure why. According to the theory of big bang nucleosynthesis (BBN), isotopes of the three lightest elements—hydrogen, helium, and ...
Tech Xplore / Glasses-free 3D display is made with tiny spherical lenses
One of the most common methods of creating the illusion of 3D is the autostereoscopic display, which is based on parallax: each eye is presented with a slightly different angle of a scene. Often this is done with many tiny ...
Phys.org / Buckybomb shows potential power of nanoscale explosives
(Phys.org)—Scientists have simulated the explosion of a modified buckminsterfullerene molecule (C60), better known as a buckyball, and shown that the reaction produces a tremendous increase in temperature and pressure within ...
Phys.org / Na-ion batteries get closer to replacing Li-ion batteries
(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion (Na-ion) ...
Phys.org / Could classical theory be just as weird as quantum theory?
Quantum mechanics is often described as "weird" and "strange" because it abandons many of the intuitive traits of classical physics. For example, the ideas that the world is objective, is deterministic, and exists independent ...
Phys.org / Pen draws flexible circuits using half-meter long carbon nanotube fibers
(Phys.org)—While it may look like researchers from Tsinghua University in Beijing are sketching out an idea for a circuit on a piece of paper, they're actually using a special pen that draws real circuits using carbon-nanotube-based ...
Phys.org / Magnetic material's unusual heating effect could fry cancer cells at the perfect temperature
(Phys.org)—When exposed to a varying magnetic field, some conductive materials undergo a temperature increase of about 3-5 K over several minutes. This effect is called induction heating, and it occurs because small electric ...
Phys.org / Rapidly reconfigurable waveform generator on a CMOS chip could be used for high-speed wireless communication
(Phys.org)—An arbitrary waveform generator can, as its name implies, generate waves of almost any shape by controlling the amplitude, frequency, phase, and other wave characteristics. Waveform generators working in the radio ...
Phys.org / Nano switch could store memory using coordinated 'dance' of atoms
(Phys.org) —In one of the tiniest switches ever made, five atoms appear to "dance" around each other in a complex choreographic sequence, with their final arrangement corresponding to one of two stable states. This concerted ...
Phys.org / Scientists go to great lengths to extend superlow friction
(Phys.org)—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or "superlubricity," was known to exist only on the nanoscale. Then ...
Phys.org / No Big Bang? Quantum equation predicts universe has no beginning
(Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark ...
Phys.org / Kitchen sponge supercapacitor has many porous benefits
By dipping small pieces of an ordinary kitchen sponge into solutions of nanoscale electrode materials, scientists have created a light-weight, low-cost supercapacitor that benefits from the sponge's porous structure. The ...
Phys.org / Nuclear pasta may offer insight into strange world of neutron stars
(Phys.org)—Neutron stars, which form when massive stars collapse under their own enormous gravity, are some of the densest objects in the universe, second only to black holes. Yet while little is known about the interiors ...
