The structure of all the products was confirmed by their melting points, spectral data (IR, 1H-NMR).
From the analysis of the spectra, the IR spectral data was in good accordance with the given structure.
From the analysis of the spectra, we deduced that formylation reaction happened completely, and the product was the anticipated structure.
Products were at a high purity, and their structures were in conformity with the anticipated structures.

The chemical structure of QBPEAS was characterized by IR and 1H-NMR.
The structures and surface morphologies were characterized by IR, 1H-NMR, TEM, SEM, etc..
The molecular structure can influence the film morphology.
In a short, all of the above results indicate that molecule has the due structure.

This indicates the formation of small structures due to breaking of chain like structures of n-Butanol in the mixtures.
Also the systematic increase in the relaxation time indicates that the formation of small structures is concentration dependent.
Molecules of mixture may form multimers structures via hydrogen bonding in such a way that the effective dipole gets reduced.

There are three zirconia crystal structures: monoclinic, tetragonal and cubic phase.
The structure of whole matrix is rarefaction.
This microporus structure is very good for use.

Keywords: friction reduction, SiO2 nanoparticle, functionalization, molecular dynamics, quantum chemical calculation.
In order to achieve the desired low friction property by functionalization of the nanoparticles, atomic scale investigations such as surface structure and its property optimizations are necessary.
Application of computational chemistry methods is an effective way to analyze atomic-scale properties and to optimize the surface structure in order to customize its properties.
The QC coefficients have been adjusted to reproduce the binding energies and electronic structures of each reactant calculated by the first-principle parameterization.
