A homogeneous photocatalyst on a stable substrate is required for photocatalytic reactors in wastewater treatment. ZnO films were synthesized on stainless steel prepared by the spray pyrolysis technique at different deposition temperatures (350 to 50...

Lanthanide-doped Ca₂Nb₂O₇ offers versatile and tunable luminescence properties. Previous studies have shown that Pr³⁺-doped and Pr³⁺/Er³⁺ co-doped Ca₂Nb₂O₇ ceramics exhibit non-destructive mechanoluminescence, up- and down-conversion luminescence, an...

Perovskite solar cells (PSCs) have emerged as one of the most rapidly advancing photovoltaic technologies of the past decade, progressing from the initial demonstration of 3.8% power conversion efficiency (PCE) in 2009 to certified single-junction ef...

Dense Ce,Pr-doped YAG transparent ceramics (YAG:Ce,Pr) with enhanced red emission were fabricated by pressureless sintering in air at 1600 °C. Fine YAG powders containing 0.2 mol% Ce and varying amounts of Pr (0.04–0.32 mol%) were synthesiz...

This in vitro study evaluated the effect of two silane coupling agent application techniques (dry air and thermally activated warm air) on the interfacial properties and shear bond strength (SBS) of lithium disilicate veneers fabricated with two desi...

A comparative compositional screening of combustion behavior and phase formation during self-propagating high-temperature synthesis in B₂O₃–Al–C and B₂O₃–Mg–C mixtures was performed under the same open-air laboratory condition...

TiB₂ ceramics have a wide range of applications due to their exceptional properties. However, high relative density must be achieved to enable their use in cutting tools, wear-resistant components, body armor, and extreme environment applications. In...

This in vitro study evaluated the effects of simulated gastric acid exposure on surface roughness, color change, translucency, and mass change in four monolithic CAD/CAM restorative materials with different microstructural compositions. Rectangular s...

This study investigates the key material properties governing the long-term stability of ceramic heat-storage media exposed to severe high-temperature and high-humidity conditions (up to 950 °C under high-steam partial pressure). Candidate cerami...

Crystalline solids melt at well-defined material-specific temperatures T_m via first-order phase transitions, whereas glasses undergo continuous transformations from solid to molten states at glass transition temperatures T_g, resembling second-order t...

Production of short-fiber-reinforced carbon/carbon composites (SF-C/C composites) is typically based on the pyrolysis of short-fiber-reinforced plastics (CFRPs) produced by compression molding. The production of C/C composites is generally a highly t...

High-entropy oxide (HEO) nanoceramics based on (Y_0.2La_0.2Gd_0.2Eu_0.2Er_0.2)₂O₃ were synthesized at 600 °C for 10 min under pressures of 2, 4, 6, and 8 GPa using High-Pressure–Low-Temperature (HPLT) technology, and the resulting structural, ph...

This study presents an initial effort to develop Low-Temperature Cofired Ceramics (LTCC) using local bio-sourced materials: Saint Jacques shells and slate tiles. Chemical analysis confirms that the Saint Jacques shells provide CaO and CaCO₃, while sl...

To realize the remanufacturing of cast iron components, a WC-reinforced Fe-based composite powder was designed, and the WC/Fe-based composite coating was deposited on the HT250 substrate by laser cladding. The melting and dissolution mechanism of WC...

(Bi_0.5Na_0.5)TiO₃ (BNT)-based ceramics have attracted much attention for energy storage applications, but some fundamental issues remain unclear—in particular, how the conduction mechanism changes with composition and what role oxygen vacancies...

Thermal treatment of clay minerals induces a sequence of dehydration, dehydroxylation, and recrystallization reactions that control the properties of ceramic materials, calcined clays, and other high-temperature products. This review examines how vib...

This study evaluates the rapid tooling feasibility and structural significance of utilizing digital light processing (DLP)-printed alumina as a near-net-shape ceramic mold-insert preform route for replication of curved polymer optics. While conventio...
