Chemistry of ash-deposits on gas turbines hot parts: Reactivity of nickel, zinc and iron oxides in (Na, V, S) molten salts E.
This paper distinguishes the interactions between NiO on one hand and both ZnO and Fe2O3 on the other hand in the general complex chemistry of ash.
DTA analysis of these melts show that small zinc incorporation in Ni3V2O8 structure does not change its melting temperature or its refractory properties.
Indeed, the addition of ZnO significantly alters the ash chemistry of the Na2O-V2O5-NiO ternary system by creating a fusible NaVO3-Zn(VO3)2 phase (TMP ≈ 580°C).

In addition, the nature of the ionic liquid structures provides it with the flexibility to switch the anion part in order to attach the relevant functional group into the cation part without altering the cation chemistry.
The predictive model depends on the uni-molecular quantum chemistry calculations.
The (T moleX) Graphical Interface was utilized to create the molecules from the basic atoms and optimize the structure of the lower energy.

It is well known that the pore structure (pore volume, surface area and pore-size distribution) plays an important role in the gas adsorption on activated carbons.
Plenty of investigations were committed into the aspect of the micro structure of activated carbon and their relationship with capacity for adsorbates[4, 5].
For this purpose, it is necessary to develop ACs with similar textural properties but different surface chemistry.

The optimized structures in CDCl3 were in good agreement with the experimental data.
Most of the recent literature concerning this ligand has been focused chiefly on the selective oxidation of sulfides to sulfoxides in synthetic organic chemistry [1-13].
The ligand has been rarely studied in terms of its structure or spectroscopic properties.
We also found that the optimized structure of R4 in CDCl3 was similar with R2, it might be confirmed that R4 was not the possible structure in solvent.

In the images of non-irradiated polypropylene, the supramolecular structures have a more distinct structure and “smooth edges” (Fig. 2, a).
The effect of ionizing radiation (expansion of the MWD, the appearance of polar groups) leads to the formation of less perfect supramolecular structures when the melt is cooled - the edges of the spherulites are broken, the structure of the structures does not have a strict form (Fig. 2, b).
The presence of structured areas leads to an increase in roughness.

Looking to the future, the quantitative understaning the 4f orbital of RE contribution still need to rely on the further development of quantum chemistry theory and method.
To uncover the secret, the first thing is to understand the inner structure of the rare earths.
Not filled with electrons, the 4f electronic shell structure of rare earth elements determines that rare earths and their compounds have important magnetic properties.
The author believes that this is mainly due to its unique atomic structure; especially the 4f orbital contribution to bonding in reaction cannot be ignored.
