Room-temperature ferromagnetism in nanoparticles of superconducting materials [PDF]

open access: yes, 2007
Nanoparticles of superconducting YBa2Cu3O7-delta (YBCO) (Tc = 91 K) exhibit ferromagnetism at room temperature while the bulk YBCO, obtained by heating the nanoparticles at high temperature (940 degree C), shows a linear magnetization curve.

Synthesis of tripodal catecholates and their immobilization on zinc oxide nanoparticles [PDF]

open access: yes, 2015
A common approach to generate tailored materials and nanoparticles (NPs) is the formation of molecular monolayers by chemisorption of bifunctional anchor molecules. This approach depends critically on the choice of a suitable anchor group.
