The study was undertaken to establish the dynamics of protons, especially those in methyl groups by the methods of 1H NMR, inelastic incoherent neutron scattering and quantum chemistry calculations.
Calculation of the theoretical vibrational spectra by the methods of quantum chemistry ( density functional theory methods -DFT) permits determination of the frequency and intensity of the normal modes.
The low-temperature Gexp(ν) spectrum was compared with that calculated by the methods of quantum chemistry in the isolated molecule approach.
G(ν) spectra The optimisation of the molecule structure and the force field calculation (as the second derivative of the molecule energy with respect to the atom displacement) performed by the methods of quantum chemistry permitted determination of the positions of normal modes in the vibrational spectrum and the amplitude of the atoms' displacements from the equilibrium position.

Ono et al.[19] reported a possible chemistry of phenol assisted liquefaction: cellulose is degraded to cello-oligosaccharides and glucose by sulfuric acid catalyst, then its pyranose ring structure is subject to decomposition and then recombination of its decomposed fragments and phenols would occur in the process of liquefaction.
Therefore, it is possible to adjust the structure and properties of the end resulting liquefied products by controlling these reaction conditions.

This cable structure arises from the comparison of integration between CNT-PA6 and PA6-PA6.
When the bond between CNTs and matrix is stronger, the cable structure may be found.

So controlling of the crystal structure of PVDF membranes became very important.
Recent years,ionic liquids (ILs) are attracting much attention for applications in many fields of chemistry and industry due to their chemical stability, thermal stability, low vapor pressure and high ionic conductivity properties.
For the pure PVDF membranes, a more dense structure was found, and no obvious pore structure appeared at surface of the membranes.
As for the cross-section structure of the membrane, with the addition of ionic liquid, large finger-like pore structure formed, and a more sponge-like structure also appeared at the bottom surface of the membrane (M2 and M3).
Otherwise, the enhanced pore structure also increased the hydrophobic of PVDF membranes.

The key elements that induce pattern collapse during a drying step are the capillarity forces between structures and the adhesion forces which are dependent of the surface energy of the structures [1-2].
To continue the wet clean after Fin etch on structures having even higher aspect ratios, a drying technique using a surface functionalization chemistry (SFC) has been evaluated and introduced.
A qualitative analysis of the collapsed structures vs non collapsed structures is shown in figure 1.
Typically, 24 structures are measured over 13 locations (312 inspected structures in total).
Using a clean with the SFC implies the implementation of a post treatment which has to preserve the FIN structures to remove organic contamination that may cause gate leakage while preserving the FIN structures.
