    “…Distinctively, the feature of the synthesised γ-NA5 pellet from the conventional powder-like catalyst is that it eases the separation of the used catalyst from the biomass ash, and subsequently facilitates regeneration solely by calcination process. The loading of 20 wt.% optimised amount of catalyst itself has successfully shorten the completion of gasification process up to 135 min, which is highly feasible for a large scale industrial usage after considering the cost of the catalyst, facile preparation method, and catalyst’s effectiveness towards gasification.…”

    “…[Image: see text] Visible-lightdriven C–TiO(2) nanocomposites were prepared via a simple calcination and acid etching process. The C–TiO(2) nanocomposites were characterized by X-ray photoelectron spectroscopy, Raman spectroscopy, X-ray diffraction, transmission electron microscopy, and high-resolution TEM. …”

    “…A novel double-shelled hollow (DSH) structure of ZnTiO(3) microrods was prepared by self-templating route with the assistance of poly(diallyldimethylammonium chloride) (PDDA) in an ethylene glycol (EG) solution, which was followed by calcining. Moreover, the NH(3) gas-sensing properties of the DSH ZnTiO(3) microrods were studied at room temperature. …”

    “…This work reports for the first time the production and characterization of sol-gel materials based on a six-oxide basic system (SiO(2)–P(2)O(5)–CaO–MgO–Na(2)O–K(2)O). It was shown that calcination played a role in inducing the formation of crystalline phases, thus generating glass-ceramic materials. …”

    “…X-ray diffraction shows that thermochemical decomposition is not complete and that the sulfur present in the residue exists in the form of CaSO(4) and CaS at 1150 °C. After calcination of phosphogypsum, the analysis of the residues obtained shows that they have a chemical composition almost identical in terms of quality to that of clinker, which can further be used in the cement production.…”

    “…Here, we present a facile method for large-scale fabrication of highly compressible, temperature resistant SiO(2)-Al(2)O(3) composite ceramic sponges by blow spinning and subsequent calcination. We successfully produce anisotropic lamellar ceramic sponges with numerous stacked microfiber layers and density as low as 10 mg cm(−3). …”

    “…Here, we report a novel entropy-driven strategy to stabilize Pd single-atom on the high-entropy fluorite oxides (CeZrHfTiLa)O(x) (HEFO) as the support by a combination of mechanical milling with calcination at 900 °C. Characterization results reveal that single Pd atoms are incorporated into HEFO (Pd(1)@HEFO) sublattice by forming stable Pd–O–M bonds (M = Ce/Zr/La). …”
