The Ni-Zn-AA LHS has stability at pH 5-6 due to its lowest amount of ascorbic acid that released from the structure.
LHS and LDH have brucite-like structure so it provides the ability of ion exchange.
Based on the shown data in Table 1, it could be concluded that the layered structure of Ni-Zn LHS was formed completely.
It confirmed the presence of ascorbic acid in LHS structure.
The Ni-Zn-AA LHS has stability at pH 5-6 due to its lowest amount of ascorbic acid that released from the structure.

Existing Model for AEC Model Structure .
Therefore, the atmospheric environment capacity model in urban agglomeration shall be the structure with two purposes: the least pollution treatment costs (largest allowed emission or least abatement) and the least loss from contamination hazard (loss for human health + loss from biology + material loss), and the restrained conditions: environmental quality not exceed the NAQQS and restrained by the technology of control the pollution, i.e.: Max ∑discharging volume from every pollution source Min ∑ loss for human health + loss from biology + material loss Subject to pollutant concentration in the air in every control point ≤ NAAQS emission rate from each pollution source ≤ national quality standard emission rate from each pollution source ≥ least emission rate by present control technology Thus if we want to establish such models, we must know the method of quantitative calculation for measured loss from atmospheric contamination hazard.

The development of new easy-to-clean or even self-cleaning surfaces has recently been the main research field for ceramic tile industries that are investigating different surface structures using nanoparticles and nanocoatings.[5] In fact, among the different and interesting properties of nanomaterials, they are characterized by a mean diameter below the light wavelength and thus they are transparent if applied on a substrate or dispersed in a matrix.
TiO2 is a common semiconductor material that has three crystal structures: anatase, rutile and brookite, with atanase showing a greater photocatalytic activity than the other types of TiO2 polymorphs.

Carbon blacks (CB) are a kind of attractive carbonaceous material because its mesoscopic structure, particle shape and surface properties are special [1].
The surface chemistry of the organic portion of the recovered carbon black obtained at low pyrolysis pressures is close to that of the commercial carbon black N330 initially present in the rubber.
Modification resulted in the substantial changes to the inherent properties like surface chemistry and morphology of the commercial carbon black to explore its potential as sorbent.
Momose M [42] invented an aqueous carbon black dispersion liquid contains a surface modified carbon black and a non-ionic surfactant having acetylene structure.

In general,95% industry solid wastes come from the following industries: the mineral industry, the production and supply of electric power and steam, the industry of ferrous metals, chemistry industry, the industry of nonferrous metals, food and tobacco manufacturing industry, building materials and other nonmetal mineral manufacturing industry, manufacturing industry of machine, electronics and equipment.
In order to improve resources efficiency of social production and establish recycling economy, a series of reformatory products and industry structure adjustment are necessary.
Material industry actively adjusts the industrial structure, changes present condition of high resource and energy consumption to realizing harmony and reasonable allocation among resources, environment and materials so as to expanding requirement of culture and living.

Three-dimensional network structure of binder formed via crosslinking reaction at high temperature, entraps pigments on textiles.
Existence of double bonds in natural rubber (cis-1,4-polyisoprene) gives a potential of crosslinking reaction when the latex exposes to high curing temperature and the network structure of rubber film may somehow be formed in a similar way as the synthetic binder (Fig.3).

The mineralogy was determined using X-Ray diffraction identifying the following phases: Ca5(PO4)3OH, Ca2P2O7, Ag3PO4, Ca5(PO4)3F and CaF2; the oxidation state of elements was determined by X-ray photoelectron spectroscopy; the morphological structure was studied by scanning electron microscopy and atomic force microscopy.
The presence of fluorine influences the crystal structure of HA forming fluorohydroxyapatite which has a higher chemical stability and lower solubility [6].
The major material variables that could influence the host response includes bulk material composition, micro or nano structure, morphology, crystallinity, surface chemical composition, surface topography, corrosion parameters, ion release profile, metal ion toxicity (for metallic materials), degradation profile, among others [15].
