Fixed denture durability is characterized as a period of time for which a dental appliance satisfies functional and esthetic requirements. First of all, its durability is based on the properties of materials it is made of, and depends, at the same time, on the characteristics of biological environment, in which the denture is placed. The purpose of this study was a long-term monitoring of chang...

Zinc-air batteries have several advantages in comparison with the lithium-ion technology as they enable use of earth-abundant elements, work at low cost, are lightweight, and also much safer application. In addition to chemistry related zinc electrode, efficient stable bifunctional catalysts required for oxygen reduction reaction (ORR, discharging) evolution (OER, charging) on air-electrode sid...

Employing first-principles calculations we study the structural, electronic and magnetic properties of the [Sc1−xVx]C and [Sc1−xVx]Si alloys. In their equilibrium rocksalt structure all alloys are non-magnetic. The zincblende and wurtzite structures are degenerated with respect to the total energy. For all concentrations the alloys in these lattice structures are half-metallic with the gap loca...
