And it is expected that this information will be reflected in the XRD pattern. In this study, the lumines-cence data and XRD patterns of Sm-doped TiO2 accumulated by our group are used to construct a model to p
Crystal plane control refers to controlling the exposed crystal plane of TiO2 through surfactant treatment and surface heteroatom adsorption. Due to the low surface energy of the (101) crystal plane of anatase, it is thermodynamically more stable, and the exposed surface is often the (101) crysta...
Density functional theory calculation further proved that the oxygen vacancies at the interface between Ni nanoparticles and CeO2 could greatly enhance the adsorption of lignin dimers, and thus revealed that Ni nanoparticles neighboring the oxygen vacancies were the catalytic sites for the efficient cut ...

Preparation of Zn–Mg–Al/LDH. Full size image An X-ray diffractometer (Empyrean X-ray Diffractometer from PANalytical) was used to detect the XRD patterns of LDH before and after adsorption with Cu Kα radiation (λ = 1.5405 Å, 40 kV, 35 mA), using 2θ = 5–80◦). ...
The other method is free energy calculation using a subnano-scale spherical crystal embedded in the glass model. This method, which we called Free-Energy Seeding Method (FESM), allows us to evaluate free energy change as a function of crystal radius and to identify critical size of the ...
In order to check this assumption, the crystal growth velocities of the samples were compared at specific viscosity values. For this purpose, viscosities values obtained by beam bending and rotation viscometry were fitted by the Avramov-Milchev-equation. This enabled the calculation of viscosity ...
Full size table The crystal growth velocities of the studied glasses were determined byin situhot stage microscopy and recently published in ref.28. The crystal growth velocities of sample Nb0.1 are shown as a function of the temperature inFig. 1a) (data inTable 2). It can be seen that ...
The physical-chemical characterization showed that the adopted synthesis method allows obtaining NPs with uniform shape and size and promotes the introduction of Fe into the titania matrix, finally affecting the relative amounts of the three occurring polymorphs of TiO2 (anatase, rutile and brookite)....
Compared with a polycrystalline NCM, the primary particles of single- crystal nickel-rich NCM materials without grain boundaries are composed of a large single grain in micron size, which can effectively mitigate the particle microcracking. Simultane- ously, the basic structure of single-crystal with...
