Real and Hypothetical Intermediate-Valence Ag(II)/Ag(III) and Ag(II)/Ag(I) Fluoride Systems as Potential Superconductors.

With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...

Generation of Ag-Ag(2)O complex nanostructures by excimer laser ablation of Ag in water.

Pulsed laser ablation in liquid (PLAL) has been well established as a facile method to produce nanoparticles from bulk materials, but it is still insufficient for fabricating anisotropic and complex nanostructures, especially without the use of surfactants. Here, we demonstrate that silver (Ag) nanosheets can be produced by pulsed excimer laser ablation of bulk Ag in water via laser re-processi...

STM-induced formation of Ag islands on Ag(111)

The formation of triangular-shaped adatom islands and vacancy islands on Ag(111) at room temperature is observed in a local growth experiment. The tip of a scanning tunneling microscope (STM) vibrating normal to the surface leads to a local modification. Atoms are removed from flat terraces and renucleate as adatom islands. Simultaneously with the modification process the surface is imaged with...

AG codes and AG quantum codes from the GGS curve

In this paper, algebraic-geometric (AG) codes associated with the GGS maximal curve are investigated. The Weierstrass semigroup at all Fq2-rational points of the curve is determined; the Feng-Rao designed minimum distance is computed for infinite families of such codes, as well as the automorphism group. As a result, some linear codes with better relative parameters with respect to one-point He...
