“…In this study, we report on the structural, magnetic, and optical properties of Tb(3+)-doped CeF(3) nanocrystals prepared via a polyol-assisted route, followed by calcination. X-ray diffraction analysis and electron microscopy investigations have shown the formation of a dominant Ce(0.75)F(3) nanocrystalline phase (of about 99%), with a relatively uniform distribution of nanocrystals about 15 nm in size. …”

“…Furthermore, using this framework‐bound template, Fe atoms can be included selectively at this site in the framework by direct synthesis, as confirmed by annular dark field scanning transmission electron microscopy and Rietveld refinement. Calcination removes the organic molecules to give large pore framework solids, with BET surface areas up to 540 m(2) g(−1) and two perpendicular sets of channels that intersect to give pore space connected by 12‐ring openings along all crystallographic directions.…”

“…Due to the higher sublimability of nano-MoO(3) particles than commercial MoO(3), they more easily enter into the channels of HMCM-49 and associate with Brønsted acid sites to form active MoC(x)-type species under calcination and reaction conditions. Compared with commercial MoO(3) modified MCM-49, nano-MoO(3) modified MCM-49 exhibits higher methane conversion (13.2%), higher aromatics yield (9.1%), and better stability for the methane aromatization reaction.…”

“…A pseudo-second-order (PSO) kinetic model is applied to test the experimental adsorption equilibrium isotherms, according to both the Langmuir and Freundlich models and the characteristic parameters for each model are determined. The calcined versions of both NGM-1 and NFM-1 fit the Langmuir model with maximum sorption capacities of 0.36 and 0.26 g/g for the preferred adsorption enantiomers, d-valine and l-valine, respectively. …”

“…According to the XRD results, the re-ultrasonic effect did not change the crystal phases, and the tetragonal and orthorhombic crystal phases were preserved. The effect of the calcination time was investigated too; an increase in it led to a decrease in the irregular nanorods size but an increase in the crystallite size.…”
