CMZP and Mg-doped Al2TiO5 Thin film Coatings for High Temperature Corrosion Protection of Si3N4 Heat Exchangers
Silicon nitride (Si3N4) is a potentially good ceramic material for industrial heat exchangers. However, at elevated temperatures and in coal combustion atmospheres its lifetime is severely reduced by oxidation. To increase its corrosion resistance, the formation of a protective oxidation barrier …

Ultrasensitive CMOS-compatible lab-on-a-chip integrated photonic sensors with wideband operation
… The two preferred material platforms are silicon nitride (Si3N4) and silicon carbide (SiC) since they provide desired properties, such as a wide transparency window, a medium refractive index, and compatibility with standard complementary metal-oxide-semiconductor (CMOS) fabrication …

Nano-scale evaluation of moisture damage in asphalt
… adhesion within the asphalt binder. In addition, silicon nitride (Si3N4) tips are used. Silicon nitride resembles aggregate molecules (e.g. silica aggregate) that are used to produce asphalt concrete or pavements. Thus adhesion value measured using a silicon nitride tip can be considered as the …

Stability and bandwidth investigation of alternative structures for nanopore sensors
… Membranes with various thicknesses of Al2O3, Si3N4 and SiO2 stack con gu- rations were fabricated. The fabricated membranes were analyzed and drilled through by focused e-beam sputtering in TEM. The membranes were tested in 0.1 M and 1 M KCl solutions for IV characteristics, noise level and AC …
