In this study, new chemistry is explored through a simple, efficient and cheap method to synthesize surfactants from palm oil fatty acids.
The chemical structure is the important factor controlling the physico-chemical properties of any substrate.
Therefore, with oleic acid as a starting point, significant structure changes can be introduced requiring only straight forward chemistry.
These compounds can be identified by using MS-ToF and 1HNMR by molecular weight and structure elucidations.

The N2 sorption isotherm exemplified in Fig. 1a exhibited IUPAC type IV pattern with H2 hysteresis loop, indicating the existence of the mesoporous structure.

The similar modification of electronic structure can be induced by chemical compression via non-isoelectronic substitution in the rare-earth sublattice.
This might be due to Ce and Eu intermediate valence states which are explored in this work by means of X-ray absorption fine structure (XAFS) spectroscopy along with such parameters of local crystalline structure as interatomic distances.

In order to obtain an important azobenzene liquid crystal with high birefrience, click chemistry reaction was used to preparation the compound.
In addition, the synthesized compound was characterized by FT-IR and 1H-NMR to confirm the consistent structure, and the liquid crystal phase behaviors of phase sequences were investigated by polarizingmicroscope (POM).
When the azobenzene LC-doped blend is incorporated into an optical structure, this allows for phototuning of the spectral properties [11].
Such blends can be incor-porated into arbitrary optical structures through the use of holo-graphic photopolymerization [12].
The synthesized compound was characterized by FT-IR and 1H-NMR to confirm the consistent structure, and the liquid crystal phase behaviors of phase sequences was investigated by polarizingmicroscope.
