The sensing characteristics of a yttria-stabilized zirconia (YSZ)-based sensor utilizing a NiO sensing-electrode (SE) towards toluene (C(7)H(8)) and interfering gases (C(3)H(6), H(2), CO, NO(2) and C(2)H(5)OH) were evaluated with a view to selective C(7)H(8) monitoring in indoor atmospheres. The fabricated YSZ-based sensor showed preferential responses toward 480 ppb C(2)H(5)OH, rather than the...

SOFC solid electrolytes are known for their ionic conductivity characteristics, which increase with increasing operating temperature. Using COMSOL Multiphysics numerical simulation, analysis of power performance yttria-stabilized zirconia (YSZ) and lithium sodium carbonate – gadolinium-doped ceria ({LiNa}2CO3-GDC) was conducted to determine the potential these in application SOFC. The YSZ diffe...

This study aims to investigate the microstructural alterations, mechanical properties, sliding wear behavior, and corrosion properties of Al-15%Mg2Si composites with different contents yttria-stabilized zirconia (YSZ). YSZ (0, 3, 6, 9 wt.%) were fabricated using stir-casting technique. The characterized by means optical microscopy (OM), scanning electron (SEM) equipped energy-dispersive spectro...

Ceramic dental crowns composed of yttria-stabilized zirconia（YSZ）were fabricated by stereolithographic additive manufacturing（STL-AM）. The YSZ composite appeared translucent on crown surfaces. In graphic modeling, installation structures were designed to hold and mount the object with free nanoparticles dispersed in acrylic resins obtain a paste-like consistency for STL processing. An ultraviol...

The influence of electrode configuration on the impedancemetric response of nitric oxide (NO) gas sensors was investigated for solid electrochemical cells [Au/yttria-stabilized zirconia (YSZ)/Au)]. Fabrication of the sensors was carried out at 1050 °C in order to establish a porous YSZ electrolyte that enabled gas diffusion. Two electrode configurations were studied where Au wire electrodes wer...

The validation of a ball-on-ring, equibiaxial flexural strength method to obtain the transverse rupture (TRS) right cylindrical ceramic specimens was performed in this study. Validation test achieved using commercially available engineered high purity alumina disks and finite element (FE) model analysis. validated fixture then used TRS Weibull statistical analysis MgO-partially stabilized zirco...

Thermal barrier coatings (TBCs) are commonly used to protect gas turbine components from high temperatures and oxidation. Such consist of ceramic top coats metallic bond coats. The mismatch in thermal expansion the coat, coat component material is one main factor leading failure coating system. Columnar-structured offer an enhanced tolerance strain during cycling. On a flat coated surface, thes...

During the last years, interest in application of additive manufacturing (AM), also known as 3D printing, becomes extremely popular various fields medicine including dentistry. Currently, metal and ceramic materials are most often used for dental prosthetics manufactured by printing. The yttria-stabilized zirconia (YSZ) ceramics has become best alternative metal-based restorations. In this rega...
