Abstract: Calcite is a common scale in water cooling systems treated and controlled with Organic phosphonates.
These three phosphonate additives are similar in structure.
Their ionized structures and names are shown Figure 1.

Abstract.
It was demonstrated that the chemical composition and physical structure of ceramics are the major factors initiating the osteoinduction of biomaterials and determining their osteoinductive capacity [1, 2].
So the composite materials in this experi- ment have the similar structure to that of osteoin- ductive calcium phosphate ceramics.
Besides microstructure, the chemistry may be another important factor influencing osteoinductivity of the calcium phosphate ceramics.

It was known that its structure was divided into two layers; the coated glass and the metal substrate (Fig. 1 b) [12-14].
Compositions and structures of the glass samples were also analyzed using a Jeol 5410 LV SEM equipped with an Oxford Instruments INCA Penta FETx3 analytical system at Maejo University (Chiang Mai, Thailand).

The point when a sufficient measure of filler is stacked, the filler particles get closer and structure linkages, which bring about an initial conducting way through the entire material.
At last, at high stacking of the filler, the expanding number of conducting ways structures a three-dimensional system.

Abstract.
The acetic acid method is mostly reacted in fixed bed reactor, including many advantages, such as reduced backmixing, higher selectivity due to contacting with the catalyst effectively, simple structure.
This assiduous research is based on the ideas of green chemistry.
Finally, its structure under the microscope is shown in fig.1.
