Introduction Emulsion polymerization process and formulation determine the particle structure, configuration and surface properties of emulsions, also decided the stability of emulsions [1].
The particle structure and size of emulsion were observed by laser particle size analyzer and scanning electron microscopy morphology (SEM).
Particle structure, configuration and size.

The XRD analysis presents that the filler material has an amorph and crystalline structure.
All material has amorf base structure of lignin at 2θ ~ 22° [32].
Distinct peaks at 28.6° and 31.9° was a response of crystaline structure [33], [34].
The goal was to understand the resulting structure and compatibility of the material.
Both lignin and lignosulfonate exhibited amorphous and crystalline structures.

Interestingly, IONPs with different surface chemistries show different levels of toxicity.
The much broader, multi-component, peak between 2500 and 2000 cm-1 strongly visible in the spectrum from Part A is suggested to originate from and stretches in organic structures, where X, Y and Z may represent any of the atoms C, N, O and S [66].

Advances in Studies on the Adsorption of Dyes in Wastewater using Mesoporous Materials Xingxing Gu1, a, Ya Han1, b, Jinjin Chen1, c and Jianrong Chen1•2, d 1 College of chemistry and life sciences, Zhejiang normal university, Jinhua, China 2 College of geography and environmental sciences, Zhejiang normal university, Jinhua, China agarygu2010@163.com, bhanya19850113@163.com, ccjjcg@sina.com dcjr@zjnu.cn Keywords: mesoporous materials; dye; adsorption; wastewater Abstract.
Due to their large surface areas, high pore volumes, relatively even distributions of pore sizes, surfaces enriched with unsaturated groups and orderly long-range structures, the mesoporous materials have been widely applied in industries such as chemical, biomedical, environmental protection and functional materials.
The mesoporous materials have become effective adsorbents own to their unique structures and characteristics such as huge surface areas, high pore volumes, relatively even distributions of pore sizes, surfaces enriched with unsaturated groups and orderly long-range structures.
Their pore structures are readily collapsed after calcination.
In recent years, M41S family of mesoporous materials, such as MCM-41 [20-22], doped MCM-41 [23] and silane-modified MCM-41 [24,25] et al., have been accepted as one of the appropriate adsorbents for the removal of dyes from wastewater due to their unique mesoporous pore structure characterized by high surface area and pore volume (Table 1).

It has been established that the alloys have a composite structure: inclusions of continuously solid solutions based on chromium and tungsten, as well as chromium aluminides Al3(Cr, W, Fe)2, which have increased microhardness values (12.9 GPa) are distributed in the aluminum matrix.
When setting the tasks of this study, of particular interest is the use of oxide phases (scheelite concentrate) using aluminum as a reductant and obtaining a tight ingot, which will make it possible to form a uniformly distributed strengthening structure inside the aluminum matrix alloy.
