Promising graphene catalyst obtained from sticky rice

Recently, researchers from Tsinghua University, Queen Mary University of London, and Institute of Metal Research, Chinese Academy of Sciences, have reported a promising graphene catalyst obtained from sticky rice, and revealed ...

Physicists propose method for braiding light

(Phys.org)—Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would have an unusual ...

Topological protection in mechanical metamaterials

Researchers at Leiden University, the Netherlands, showed that certain crystal defects in mechanical metamaterials can harbour topologically protected motions. These mechanical states are analogues of protected electronic ...

Cosmology in the lab using laser-cooled ions

Scientists would love to know which forces created our universe some 14 billion years ago. How could – due to a breaking of symmetry – matter, and thus stars and galaxies, be created from an originally symmetrical universe ...

Searching for defects in space

Topological defects in space may have developed fractions of a second after the Big Bang. Simulations of these wormlike entities and a comparison of the simulations with cosmic background radiation measurements by the Planck ...
