We use density functional theory calculations to characterize the early stages of fluorination of silver's (100) and (110) surfaces. In the Ag(100) surface, the hollow site is the most favorable for F adatoms. In the Ag(110) surface, three adsorption

Based on the Density Functional Theory calculations, we propose a new pathway toward compounds featuring flat [AgF2] layers which mimic [CuO2] layers in high-temperature oxocuprate superconductor precursors. Calculations predict the dynamic (phonon)

In this letter, we propose ternary nickel hydrides MNiH2 (M = Li, Na) as new materials that mimic cuprate physics but have important differences and interesting properties. Ni-H bands are wider than in oxides due to shorter bond lengths and covalency

We have successfully prepared two novel mixed-valence compounds of silver, Ag(I)Ag(II)F3 and Ag(I)2Ag(II)F4. They may be considered to be long-sought strongly electron-overdoped Ag(II)F2. Their crystal structures indicate that both belong to the Clas

We present a new compound in the silver cobalt fluoride system, featuring paramagnetic silver (d9) and high-spin cobalt (d6), synthesized by solid state method in an autoclave under F2 overpressure. Based on powder X ray diffraction, we determined th

The crystal structure of KAgF3 was studied by powder neutron diffraction. KAgF3 exhibits at all temperatures an orthorhombic symmetry in space group Pnma that allows for several distortions with respect to the ideal cubic perovskite structure. At all

The use of image sequences in the form of video frames recorded on data storage is very useful in especially when working with large and complex structures. Two cameras were used in this study: Sony NEX-5N (for the test object) and Sony NEX-VG10 E (f

We apply a novel chemical capacitor setup to facilitate metallization of ionic hydrides, LiH and MgH2. It turns out that the amount of holes doped to a single layer of these materials may reach 0.72 per H atom without structure collapse; concomitant

We present theoretical study of relative stability as well as of the magnetic and electronic properties of AgF2 and CuF2, in two related structural forms: orthorhombic (ambient pressure form of AgF2) and monoclinic (ambient pressure form of CuF2), us

The Landsat 8 satellite which was launched in 2013 is a next generation of the Landsat remote sensing satellites series. It is equipped with two new sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). What distinguishes
