A Stabilization Mechanism of Zirconia Based on Oxygen Vacancies Only
, 2002 The microscopic mechanism leading to stabilization of cubic and tetragonal forms of zirconia (ZrO$_2$) is analyzed by means of a self-consistent tight-binding model.

Microwave synthesis of ZrO₂ and yttria stabilize ZrO₂ particles from aqueous precursor solutions [PDF]
, 2012 Zirconia and Yttrium stabilized zirconia are well-known ceramic materials. Scaling down the dimension of these ceramics can result in a faster sintering process at lower temperatures.

X-ray photoemission spectroscopy determination of the InN/yttria stabilized cubic-zirconia valence band offset [PDF]
, 2007 The valence band offset of wurtzite InN(0001)/yttria stabilized cubic-zirconia (YSZ)(111) heterojunctions is determined by x-ray photoemission spectroscopy to be 1.19±0.17 eV giving a conduction band offset of 3.06±0.20 eV.

Absence of Ferromagnetism in Mn-doped Tetragonal Zirconia
, 2011 In a recent letter, it has been predicted within first principle studies that Mn-doped ZrO2 compounds could be good candidate for spintronics application because expected to exhibit ferromagnetism far beyond room temperature.

Catalytic coatings on steel for low-temperature propane prereforming to solid oxide fuel cell (SOFC) application [PDF]
, 2009 Catalyst layers (4–20 lm) of rhodium (1 wt%) supported on alumina, titania, and ceria–zirconia (Ce0.5Zr0.5O2) were coated on stainless-steel corrugated sheets by dip-coating in very stable colloidal dispersions of nanoparticles in water.

Advanced Engineering Materials, EarlyView.In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...
