Researchers inadvertently boost surface area of nickel nanoparticles for catalysis

Scientists have discovered that a technique designed to coat nickel nanoparticles with silica shells actually fragments the material - creating a small core of oxidized nickel surrounded by smaller satellites embedded in a silica shell. The surprising result may prove useful by increasing the surface area of nickel available for catalyzing chemical reactions.

Researchers achieve significant breakthrough in topological insulator based devices

Researchers have, for the first time, successfully demonstrated room temperature magnetisation switching driven by giant spin-orbit torques in topological insulator/conventional ferromagnet heterostructures with an extremely low current density, that can address the issue of scalability and high power consumption needed in modern spintronic devices.

Freezing electrons makes them get in line

New research suggests that electrons in a two-dimensional gas can undergo a semi-ordered (nematic) to mostly-ordered (smectic) phase transition, which has been discussed in physics theory but never seen in practice before.
