Many historic structures in the word were built using natural cement [2].
Restoration of historic structures has become eminent, instead of demolishing them.
The chemistry of cement and concrete.

Introduction The production of functional activated carbon materials originating from renewable resources using benign and economically processes is becoming a hot topic in material chemistry nowadays [1].
A proportion of K will be intercalated into carbon layer to form carbon-potassium intercalation compounds, so the carbon structured is destroyed and generates micropores.
It seems that the porous structure of activated carbon contributes to the high specific capacitance at higher scan rates.

Discussion PAL studies of the free volume in polymer sorbents and membranes of intrinsic microporosity, such as PTMSP, amorphous Teflons (AF), novel spiro-linked benzodioxane polymers PIM [4,8,11] of the rigid structure are interesting because of the large scale of variations of the size and shapes of EFV in these materials.
Results on dynamic simulation of size distributions of EFV in a number of polymers (Fig.3 [3]) show that the distributions drdrn /)()(  are not of Gaussian type, have essential asymmetry and correspond more to heterogeneous structure of polymer glasses.

So TiCN can be used in many fields, such as machine, chemistry, automobile and aerospace etc[1].
The structure of as-synthesized materials was ex situ monitored by X-ray diffractometry (XRD) with Cu Kα radiation.
Finally the developed TiCN structure is seen after milling for 50 h.

For a long time many experts and scholars have research on te bauxite of rocks and minerals, chemistry, sedimentary environment, provenance, mineralization age [1-11].
Binary structure of bauxite is clear, generally, diaspore takes the content of 40%-95% in the middle- upper part, the rest are mainly clay minerals like kaolinite, chlorite and illite etc.
Clay rocks exhibit homophaneous structure.

The structure of the films was investigated by X-ray diffraction.
Analysis of the fine structure of X-rays absorption by Co atoms showed that Co occupies Zn position in the lattice [10].

Finite element analysis is used extensively in the design of structures and sub-components.
Rubber materials are deformed, their network structure lose their stiffness due to modification and reformation, and damping properties change.

Microwave Synthesis and Catalytic Applications of Novel Cobalt Incorporated Nickel Phosphate Isak Rajjak Shaikh and Sang-Eon Park* Lab. of Nano-Green Catalysis and Nano Center for Fine Chemicals Fusion Technology, Dep't of Chemistry, Inha University, Incheon 402-751, Korea.
Recently, we discovered the nanoporous nickel (II) phosphate VSB-5 having very interesting zeolitic properties.4 The VSB-5 structure is based on a 1D 24-ring channels system, consisting of HPO4, PO4, and water molecules bound directly to octahedrally coordinated Ni 2+ .
Green colored novel cobalt incorporated nickel phosphate material was obtained and its structure was confirmed and characterized by powder X-ray diffraction (XRD) pattern, Scanning Electron Microscopy (SEM), UV-Vis diffuse reflectance spectroscopy (UV-DRS) and thermo gravimetric analysis (TGA).

Experimental Paracetamol with chemical structure shown in Fig. 1 was purchased from Aladdin Chemistry and used as received.
Fig. 1 The chemical structure of Paracetamol A stock solution of paracetamol (APAP) was prepared fresh with deionized water before each run.
