Refractories are defined as "non-metallic materials having those chemical and physical properties that make them applicable: for structures, or as components of systems, that are exposed to environments above 1,000 °F (...

Abstract Multi-component nanofluids have attracted increasing attention for advanced heat transfer and energy systems; however, experimental data on oxide-based quadri-hybrid nanofluids, particularly regarding their coup...

We have studied the effect of the pelletization pressure on microstructural and electrical transport properties of superconducting ceramics with starting composition given by the formula Bi 1.65Pb 0.35Sr 2Ca 2.5Cu 3.5O 1...

Abstract A novel biphasic Dy2Hf2O7-HfO2 composite was synthesized via a solid-state reaction route for potential thermal barrier coating (TBC) applications. X-ray diffraction confirmed that the reaction between Dy2O3 and...

Abstract Concrete production’s environmental impact has driven the use of supplementary cementitious materials like sawdust ash (SDA) and admixtures such as Conplast to enhance sustainability and performance. This stud...

Abstract A promising approach for constructing visible-light-responsive photocatalysts with superior activity is realized through the surface grafting of wide-band-gap semiconductors with earth-abundant elements. Consequ...

Abstract The glass transition temperature ( $$\:{T}_{g}$$ ) is a pivotal parameter for amorphous polymers, influencing their behavior under different thermal properties. Assessing $$\:{T}_{g}$$ is crucial for evaluating ...

Abstract Nitrogen-doped carbon dots (CDs) were prepared from essential fluorescent amino acids, such as lysine (Lys), phenylalanine (Phe), tyrosine (Tyr), and tryptophan (Trp) by two routes, microwave and teflon-lined au...
