The structure of lignosulfonate has some relationship to water reducing property.
The relationship between water reducing properties and lignin structure has not been understood clearly, efforts should be made to investigate the molecular structure and chemical modification of lignin in order to improve the characteristics of lignin.
Effects of Oxidation Condition on LS Structure Researches on model compounds[9,10] find that lignin is a three dimensional high molecular compound which is composed of phenyl propane units linked through ether and carbon-carbon bonds.
Hydroxyl group in lignin structure includes phenolic hydroxyl and aliphatic hydroxyl groups.

The single crystal X-ray structure of Fe(TMPP)Cl, recrystallized by vapor diffusion of diethyl ether into dichloromethane solution, was determined.
The crystal structure and Raman results provide further support for the hypothesis that the supramolecular interactions, including C-H···π and C-H···Cl hydrogen-bond interactions, and π···π interactions influence the excitonic enhancement of the n4 band when exciting with near-IR wavelengths.

The molecular structure of imidazoline is consist of three parts (its molecular structure is shown in Fig.1): a five-atom ring with nitrogen element (part A), a long hydrocarbon chain (part B, R1), and a pendant side chain with an active functional group (part C, R2).
Zhang Jun et al. [10] evaluated the corrosion inhibition performance of four1-R-2-undecyl -imidazoline compounds (R=CH2COOH (A), CH2CH2OH (B), CH2CH2NH2 (C) and H (D)) for carbon steel by using quantum chemistry and molecular mechanics methods.

Then the nanoparticles were encapsulated within a polysiloxane shell to form core-shell structured particles.
In both cases nanoparticles are in good dispersion and present a clear core-shell structure.
Emission spectra of nanoparticles before (core) and after encapsulation (2SiOx /Gd ) prepared by NaOH and Bu4NOH addition Conclusions: Core-shell structured nanoparticles Gd2O3:Tb3+ /SiOx have been successfully synthesized by a two-step process.

One potential strategy could be by using hydrotalcite (HT) that have a layered structure which carries positive charge at each layer which are compensated with anions at the interlayer region [14].
