Laser solid-phase synthesis of graphene shell-encapsulated high-entropy alloy nanoparticles

Oct 18, 2024 (Nanowerk News) Rapid synthesis of high-entropy alloy nanoparticles (HEA NPs) offers a new opportunity to develop functional materials in various applications. Although some methods have successfully produced HEA NPs, these methods generally require rigorous conditions such as high pressure, high temperature, restricted atmosphere and limited substrates, which...

Shape-shifting ceramic nanomembranes offer new possibilities for robotics and flexible electronics

Oct 17, 2024 (Nanowerk Spotlight) Ceramic nanomembranes, which are thin films of oxide materials with thicknesses typically measured in nanometers, have emerged as a promising platform for creating highly flexible and functional structures. These materials combine the mechanical strength of ceramics with the flexibility of nanoscale membranes, making them suitable...

Magnetic octupoles overcome problems with antiferromagnets

Oct 17, 2024 (Nanowerk News) Physicists at RIKEN have demonstrated how ultrafast, low-power-consumption memory devices could be realized by replacing conventional magnetic materials with novel ones ("Current-driven fast magnetic octupole domain-wall motion in noncollinear antiferromagnets"). In conventional hard disk drives, the magnetic disk has to be physically moved to read...
