Josephson current and $\pi-$state in ferromagnet with embedded superconducting nanoparticles

, 2010
On the basis of Usadel equations we investigate superconductor/ferromagnet/superconductor (S/F/S) hybrid systems which consist of superconducting nanostructures (spheres, rods) embedded in ferromagnetic metal.

Electronic structure of porphyrin-based metal– organic frameworks and their suitability for solar fuel production photocatalysis [PDF]

, 2015
Metal–organic frameworks (MOFs) can be exceptionally good catalytic materials thanks to the presence of active metal centres and a porous structure that is advantageous for molecular adsorption and confinement.

Metallic Spintronics and Surface Science

Hyomen Kagaku, 2011
Electrons convey not only an electric charge but also a magnetic charge. Spintronics aims to achieve electronic devices with new capabilities by using both the charge and spin of electrons in solids. This area is now developing with advances in surface science.
