Natural van der Waals heterostructural single crystals with magnetic and topological properties

Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, ...

Cosmic radiation causes fluctuations in global temperatures, but doesn't cause climate change

(Phys.org)—Unlike electromagnetic radiation, which consists of massless and accelerated charged particles, galactic cosmic rays (CR) are composed mostly of atomic nuclei and solitary electrons, objects that have mass. Cosmic ...

Solitary acoustic waves observed to propagate at a lipid membrane interface

(Phys.org) —Defining the essential character of the action potential of neurons has proven to be an elusive task. As typically happens, the biggest advances seem to have been made early on. In this case it was Hodgkin and ...

Metallic-to-semiconducting nanotube conversion greatly improves transistor performance

(Phys.org) —Future transistors made of semiconducting single-walled carbon nanotubes (s-SWNTs) have the potential to perform much better than today's transistors. However, when SWNTs are grown in bulk, only about two-thirds ...

Physicists extend special relativity beyond the speed of light

(Phys.org)—Possibly the most well-known consequence of Einstein's theory of special relativity is that nothing can travel faster than the speed of light, c. According to the mass-energy equivalence formula E = mc2, an object ...

A second look at supernovae light: Universe's expansion may be understood without dark energy

(PhysOrg.com) -- The 2011 Nobel Prize in physics, awarded just a few weeks ago, went to research on the light from Type 1a supernovae, which shows that the universe is expanding at an accelerating rate. The well-known problem ...

Tiny battery is also a nanomotor

(PhysOrg.com) -- Measuring just 3.6 micrometers long, one of the smallest batteries ever made won’t be powering our electronic devices anytime soon, but it does serve as a self-powered nanomotor that is surprisingly ...
