Superconductivity at 18 K in potassium-doped C60
THE synthesis of macroscopic amounts of C60 and C70 (fullerenes)1 has stimulated a variety of studies on their chemical and physical properties2,3. We recently demonstrated that C60 and C70 become
Sodium Hydride as a Powerful Reducing Agent for Topotactic Oxide Deintercalation: Synthesis and Characterization of the Nickel(I) Oxide LaNiO2
The capability of sodium hydride as a reducing agent in oxide deintercalation reactions is explored. The Ni(III) perovskite LaNiO3 can be reduced topotactically to LaNiO2, isostructural with the
Bulk superconductivity at 38 K in a molecular system.
It is shown that superconducting Cs(3)C(60) can be reproducibly isolated by solvent-controlled synthesis and has the highest Tc of any molecular material at 38 K, and the observed Tc maximum is attributed to the role of strong electronic correlations near the metal-insulator transition onset.
An Adaptable Peptide-Based Porous Material
A crystalline porous solid with adaptable porosity is reported, in which a simple dipeptide linker is arranged in a regular array by coordination to metal centers, suggesting an energy landscape similar to that required for protein folding.
Designing switchable polarization and magnetization at room temperature in an oxide
This work combines ferroelectricity and ferromagnetism at room temperature in a bulk perovskite oxide, by constructing a percolating network of magnetic ions with strong superexchange interactions within a structural scaffold exhibiting polar lattice symmetries at a morphotropic phase boundary.
Designed Multifunctional Nanocomposites for Biomedical Applications
The assembly of multifunctional nanocomposite materials is demonstrated by exploiting the molecular sieving property of SBA‐16 nanoporous silica and using it as a template material and the functionalization approach is extendable to other applications, e.g., fluorescence–magnetic dual‐imaging diagnosis.
