Nanometer‐Sized Nickel Hollow Spheres

Abstract

In the “From our sister journals” section of Issue 8/9 of Small (pp. 780–781), we highlighted the above-titled paper by Z. Xu and co-workers, which will soon be published in Advanced Materials and is currently available online through that journal’s Early View service (DOI: 10.1002/adma.200500174) . Unfortunately, incorrect text was used in the report for this article, for which we apologize. The correct text is given below: Hollow nickel spheres of 50–60 nm diameter have different properties from bulk nickel. For example, the authors demonstrate that the spheres exhibit a long-range magnetic ordering transition at 575 K and enhanced coercivity. The facile synthesis of such spheres by mild hydrothermal redox reaction of nickel dodecylsulfate with NaH2PO2 is described.
