Sulfur and a polystyrene derivative were combined to form thermally-healable and recyclable composite materials with dramatically increased structural integrity versus sulfur alone.
We have developed a method for laser beam manipulation by using a colloid of nickel nanorods produced by electroplating chemistry. It is shown that the shape of the laser beam passing through a colloid of nickel nanorods can be altered by varying the applied magnetic field. This effect is caused by multiple scattering and diffraction of the laser beam by the nanorods. Compared with spherical nanoparticles, magnetic nanorods are better suited for illumination applications because they are stable in a rotating magnetic field. By rotating the diffraction pattern, one can illuminate a large area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
